19161 GiraultÌÔNe Encyrtida from North America 41 inflatus Lubbock, the famous honey ant of Central Australia, recently received from the Museum of South Australia, shows that what I described as Camponotus (Mynnamblys) aurofasciatus (p. 817) is merely the hitherto undescribed minor worker of Lub- bock's species. Fore1 is probably right in assigning it to the subgenus Mrymophyma.
NEW ENCYRTIDAE FROM NORTH AMERICA.
BY A. A. GIRAULT,
Bureau of Entomology, U. S. Department of Agriculture. Signiphora flavopalliata occidentalis Howard. Two females from Chrysomphalus aurantii citrinus, Avondale, Cal., October 24, 1911. P. H. Timberlake. 14527 D. Signiphora thoreauini sp. nov.
Female: Length, 0.55 mm. Differs markedly from aleyrodw in having the antennal club all black, the cephalic part of the mesoscutum is only slightly darkened, the band on the abdomen is slightly shorter. From basilica in lacking the disto-marginal spot on the abdomen, the less colored cephalic thorax, the wholly black club and its greater length. From lutea as from aleyrodis and in its greater slenderness.
From one female on a slide labelled "From Aspidiotus hederce on Soy, Santa Barbara, Cal., November 14, 1911. P. H. Timber- lake. 14594 C." Type: Catalogue No. 19809, U. S. N. M., the above specimen.
Neosigniphora elongate sp. nov.
Female: Length, 1.35 mm. Rather long in proportion to its width. Agrees with the description of Signiphora australica Girault (the legs, however, dark except the yellow tarsi and the yellow dusky front legs) ; fore wings clearer near tip and under all of submarginal vein; the marginal cilia at apex are over half the greatest wing width. Hind wings broad. Differs notably from australica in the antennal club which is slender, six or more times Pncht 23:41-49 (1916). hup Wpsycht einclub or@3/23-IMl.htinl

the foregoing female.
Aneristus oculatipennis sp. nov.
Female: Length, 1.65 mm. Black, the tarsi white; apex of .
scutellum very narrowly around the margin and a broad band across the scutum just back of the, cephalic margin, yellowish white; band on scutum occupying somewhat over a third of the surface. Propodeum centrally at apex suffused with yellowish. Body very finely scaly, the head and thorax with numerous, small setigerous punctures, densest on the scutum. Cephalic femora strongly compressed.
Fore wings hyaline but with a large, three- fourths-complete circular smoky ring from somewhat less than the distal two thirds of the marginal vein and extending beyond the venation, its open fourth facing the caudal wing margin and partly closed by a fainter dusky stripe opposite the opening and along the caudal margin; the distal margin of the ring is less than its width (not diameter) from the blade's apex; this ring makes a central, large ocula some distance distad of middle, opposite distal marginal vein. Stigma1 vein sessile, minute, globular. Middle tibia1 spur long and stout as in normal encyrtids. Axillae ad- vanced. Parapsidal furrows mere sutures. Caudal femora and tibia compressed, the tibias with stiff black bristles dorsad and with two stout, black, subequal spurs. Mandibles broadly sub- truncate but bidentate as in Baoanusia, the first tooth shorter than the large truncate second one.
Scape pale beneath; flagellum
subcylindrical, the funicle joints a little flattened, 1 nearly as long as the scape, three-fourths longer than wide at apex, 3 a little longer than wide, much larger than the pedicel; club 1 slightly wider than long. One distinct ring-joint. Maxillary palpus %jointed, the second joint ending in a long slender bristle; labials 1-jointed and similarly terminated.
Club well-defined.
From five females reared from Saissetia oleoe, Catacaos, Peru. The date of the rearing is September 14, 1912. Rust, collector.

19161 GiraultÌÔNe Encyrtidce from North America 43 Types: Catalogue No. 19211, U. S. N. M., four females on two tags plus a slide bearing appendages.
Nebaocharis gen. nov. (Ectromini)
Female: In Ashmead's table runs to Anusia Foerster but differs in having the antenna1 club solid, the ovipositor exserted for three fourths the length of the abdomen, wings are present in the shape of large scales and the head is not so long, not so nar- rowed beneath the eyes, the cheeks short. Also the pronotum is less conical, shorter than the scutum or scutellum. Abdomen slender, depressed, its segments very indistinct. Head subquad- rate but somewhat narrower toward the mouth (cephalic aspect), the face lenticular but the short, rather shallow scrobes forming a short semi-circle. Axillae apparently rather widely separated. Hind tibia1 spur single.
Type: N. hemipterus, sp. nov.
Nebaocharis hemipterus sp. nov.
Length, 1.00 mm. Dark brown, the abdomen, antennae, ex- truded valves of the ovipositor and the hind legs, purplish black; scutellum nearly black. Legs, including the caudal tibia just below knee and the caudal tarsus, yellow. Body glabrous or nearly but the head coarsely scaly. Pedicel not flattened, slightly longer than wide, slightly longer than funicle 3 which is slightly the longest, 6 subequal to 2, 1 cupshaped and smallest, all wider than long and compressed; club conical, no wider than the funicle and about half its length. Scape greatly dilated. Flagellum clothed with very short hairs.
Described from one female in the U. S. N. M. collections, labelled "Colorado, 2019. C. F. Baker." Type: Catalogue No. 19312, U. S. N. M., the specimen on a tag, the head and a hind leg on a slide.
Xanthoencyrtus Ashmead ( = Scelioencyrtus Girault.) . The original description of Xanthoencyrtus disagrees with my own of Scelio2ncyrtus, which is correct. The club is %jointed,
and the genus must at present be regarded as an Ectromine. Xan-
tho2ncgrtus nigroclavatus Ashmead appears to be common in the United States; through the Bureau of Entomology I have seen a series of both sexes labelled "Webster No. 11811, Elkpoint, S. D.

Formicencyrtus gen. nov. (Encyrtini)
Female: Head ant-like, held nearly horizontally. Runs close to Anusia Foerster but the abdomen is somewhat as in Anastatus, that is depressed (the ovipositor shortly extruded) but in shape it is broadly oval (dorsal aspect), the second segment occupying about half of the surface, segment 6 two thirds as long as 2, the others short. The wings are like large scales but veinless and inconspicuous.

Fisher."
Type: Catalogue No. 19316 U. S. N. M., a female on a tag; five female paratypes.
Ceraptroceroideus Gen. nov. (Encyrtini) . Female: In my table of genera runs to Ceraptrocerus Westwood but wingless, the head is not oblong but subquadrate (cephalic aspect) and the second segment of the abdomen occupies nearly half of the surface, the sixth next largest, two-thirds the length of the second. Pronotum extremely short. Scutum wider than long but as long or nearly as the normal scutellum whose rounded apex reaches to the base of the abdomen. Axillae separated for some distance. Vertex flat, the face inflexed, the frons prominent. Vertex of moderate width. Mandibles with the inner two teeth formed by a concaved broad second inner tooth whose lateral or dorsal apex is acute.

Purplish black, the scutellum except lateral and caudal margins narrowly and the rest of the dorsal thorax, except the tegulas and much of the surface of the scutum, reddish brown. Head purplish black, the vertex bright lemon yellow, except the lateral margins unnarrowly along the eyes and the cephalic margin broadly. Face with a broadly curved, narrow lemon yellow stripe across it just under the vertex far dorsad of the antennae, its (lateral) ends terminating under the eye ends. Lateral ocellus in the mesa1 margin of the lateral black border of thevertex, over its diameter from the eyes. Head finely scaly. Eyes partly on the vertex, the cheeks longer than them. Cephalic legs purple

================================================================================

48 Psyche [April
Middle legs purple except the same tarsal joints and the distal two- thirds of the tibiae, this latter white portion with a black cinctus at its middle. Caudal legs all purple, except the three proximal tarsal joints and a broad white cinctus a little proximad of the middle of the tibiae. Abdomen shining, subglabrous. Dorsal thorax scaly, the scutellum more densely so; scutum with sparse pubescence. Antennae wholly flat. Pedicel triangular, slightly longer than funicle 6. Scape greatly dilated. Funicle joints decreasing in width, increasing in length distad, 6 somewhat wider than long, 1 over twice so, all the joints with their distal margin concave. Club conico-cylindrical, its first joint subquadrate, largest. Fore wings with black, scattered stiff bristles disco-distad and from its cephalic margin, with a fuscous dash across at the thickening of the submarginal vein, a dusky spot against the apex of the venation and an irregular dusky blotch across the apex. What appears to be the male is very different-winged, the marginal vein somewhat longer than wide, the postmarginal just developed, the stigma1 very short, half the length of the marginal. The wings are hyaline and fully developed. Vertex flat but shorter than in the female, the frons less prominent. The antennae are filiform, the club solid, the scape only compressed-cylindrical, somewhat shorter than the club; pedicel globular; funicle joints cylindrical, 1 longest, nearly twice longer than wide, 6 somewhat longer than wide. Funicle and club with rather long, scraggly hairs.
The legs are concolorous except the proximal four tarsal joints of the first two pairs of legs, the proximal joint of caudal tarsi, the cephalic knees and tips of cephalic tibiae, middle knees and tips of middle tibiae and a white central cinctus on middle tibiae (therefore, two concolorous cincti; the knees include the base of the tibiae and the apex of the femur). The fore femur, caudal femur and tibia are compressed. The head of the male is wholly concolorous.
Described from two males, one female "From Aspidiotus he- lianthi Parr on Eugerion canadense, Wellington, Kans., October 8, 1908. E. G. Kelly." Types: Catalogue No. 19317, U. S. N. M., the above specimens on tags with a slide bearing a male head and fore wing and female head, legs, antenna and fore wings. One male a paratype.

Giruult-New Encyrtidce from North America Paracopidosomopsis Gen. nov. (Encyrtini) . Female: The same as Berecyntus Howard but the mandibular teeth are small and subequal. Type: B. floridanus Ashm. This species is closely allied with the so-called Copidosoma truncatellum Dalman (at least specimens from Europe in the U. S. National Museum, so labelled) which is congeneric, but the Amer- ican species differs in having a distinct, rectangular fuscous patch against the stigmal and marginal veins with a more suffused area caudad of it, while in the European species the wings are hyaline. Otherwise the two are certainly much alike. Mr. A. B. Gahan has identified a series offloridanus as truncatellum but for the present I do not think the two-can be regarded as the same. These speci-
mens were labelled "Laf. 11. Lafayette, Ind., J. J. D. Reared
from cabbage Plusia larva."
Berecyntus Howard.
In my table of genera runs to Copidosomopsis Girault but differs in the following essentials: The marginal vein is somewhat longer than wide, the postmarginal distinct, about half the length of the marginal, the abdomen is broader, flat and subcordate, the stigmal vein is slightly longer than the marginal. Axillae rather broadly joined. Mandible with the third tooth minute, the first long, over twice the length of the second which is over four times the size of the third. Ring joint very minute. Club solid, obliquely trun- cate. Hind tibia1 spur single, the middle one enlarged. Genal suture absent. Scrobes not reaching to the middle of the face yet distinct, of tolerable length, forming an inverted "V." Club wider than the funicle and about three fourths its length. Berecyntus bakeri Howard, var. gemma, var. nov. Female: Length, 1 .I$ mm. Metallic blue-green, the middle knees and all tarsi except the distal joint, reddish-brown, the vena- tion blackish, the fore wings lightly infuscated from the head of the submarginal vein distad to the apex. Funicle joints increasing gradually in width distad, 1 quadrate not half the length of the pedicel, subequal to 2, 6 somewhat wider than long. Pedicel dis- tinctly longer than wide at apex, nearly half the length of the club which is a little shorter than the body of the scape. Hind wings
