166 Psyche [Sept.-Dec.
MILLIPEDS PRINCIPALLY COLLECTED BY
PROFESSOR V. E. SHELFORD IN THE
EASTERN AND SOUTHEASTERN STATES
BY H. F. LOOMIS
Coconut Grove, Florida
In 1942 and 1943, Professor V. E. Shelford, University of Illinois, Champaign, Illinois, made extensive collections of mil- lipeds in many of the states east of the Mississippi, with some collecting having been done in northeastern Mexico in 1942. These collections were sent to me for study, the result of which constitutes a large part of this paper. Records of established species have been limited to specimens that could be completely identified; no records of females or immature specimens, of which there were considerable numbers referable only to the genus, have been included as they appeared to be of little faun- istic value. Descriptions of several new forms collected by others have been included in the paper but where a collector is not named in connection with any species, new or old, he is understood to have been Professor Shelford. Type specimens are deposited in the Museum of Compara- tive Zoology, Cambridge, Massachusetts. Paratype specimens, where available, have been deposited in the U. S. National Museum.

CLEIDOGONZDB
Pseudotremia sublevis sp. nov.
One male (type) and a dozen other specimens including ma- ture females and juveniles collected in Tony's Cave, Giles Co., Virginia, May 9, 1943 by H. W. Jackson, Virginia Agricultural Experiment Station, Blacksburg, Virginia. Diagnosis: In the princeps series but with even fewer dorsal tubercles than found in P. vaZga and with less prominent shoul- ders than other species in the series; gonopods differing from all other species.
Fig. 1. Pseudotremia sublevis. a, Gonopods ; b, Ninth leg ; c, Bifid laminae. Description: Size large, exceeded only by princeps, maximum length 30 mm.; body cylindrical, not rapidly reduced in width at either end, the females even less fusiform than the males with body widest at about segment 9 or 10; color slate blue- gray.

168 Psyche [Sept.-Dec.
Ocelli 18 or 19, in 6 series paralleling the back margin of the head, 4,4,4, 3, 2, 1 ; counting forward, 5,14,4, 3, 2, 1. First segment with lateral limits sharply angled, not at all swollen; shoulders of segment 2 small but thereafter increasing in size and thickness to segment 6 or 7 after which their prom- inence decreases and no definite shoulders are evident after segment 20; none of the shoulders elevated as in princeps or simulans. In the type, tubercles are present adjacent to the shoulders as far forward as segment 7 or 8; but in the other specimens the dorsal surface of segments smooth and shining and with no tubercles on the anterior half of the body and with only a few small indistinct ones near the posterior margin ad- jacent to the shoulders of segments at the third quarter of the body behind which none are present, the tubercles small and most of them appear to be preceded by a tiny longitudinal ridge; dorsal setae short, stiff and acute.

segments slightly darker; narrow anterior margin of the first segment from behind the eyes across itshiddle bright terra- cotta, as also are the apex of the last segment and adjacent margin, margins of anal valves and the apex and free margins of the preanal scale; eyes black; antennae and legs dark horn brown.
Head with ocelli in five series paralleling the antenna1 socket - 6, 8, 9, 8, 7; clypeus having six setigerous fovea on each side; cardo of mandibles deeply concaved to receive the an- tennse, its lower edge high, forming an acute crest, lower an- terior corner produced forward into an acute lobe. Anterior margin of first segment slightly produced forward for a short distance on each side just below the eye; lower limits narrowly rounded. Second segment with downward pro- jection narrow. Surface of body finely and rather sparsely punctate, the punctae slightly more numerous on the hindbelt. Gonopods as shown in figure 2, a and b.
Seventh segment long at the middle ventrally, not in the least elevated, completely hiding the gonopods within the body. Coxse of legs 3,4, and 5 produced into moderately conspicu- ous simple conic lobes; coxae of legs 6 and 7 with smaller lobes. RHINOCRZCIDB

as compared to the size of the body; distal arm of each nearly straight in vertical view, stout, paralleling the opposite arm and terminating in two divisions which together bear some resemblance to a cupped hand with its palm outward and op- posed by the thumb.
Type: C. plancus spec. nov.
Cheiropus plancus spec. nov.
Two males, one the type, from Thomasville, Ga., July 27, 1942, collected from "climax magnolia-beach" woods, No. M-18 10; another male, Gainesville, Florida, July 24, 1942, collected in hammock, No. M-17 79.
Fig. 3. Cheiropus plancus. a, Left gonopod, posterior view ; b, Left gonopod, outer lateral view.
Length 38-40 mm., width 10 mm. Surface of dorsum quite coarsely coriaceous. Head and antennae brown, legs white; segments with dorsum brown except along posterior margin, the back half of the lateral carinae and their outer portion in front.
Gonopods as shown in figure 3, a and b.
Fourth sternum of the male narrow, scarcely exceeded by the fifth which is definitely narrower than those following; none of the anterior sterna with tubercles. In one male the posterior sternum of the segments back of the middle of the body has a

tiny conic tubercle behind, near the coxal joint of each leg. In the other 2 males there are no sternal tubercles. Following the gonopods the first joint of the legs has a small, slenderly conic #
tubercle at the ventro-distal limit in 2 males but not in the other; spine at end of second joint of the legs long and slender. Cleptoria shelfordi sp. nov.
A single male (M-1780) collected in cruising oak-pine woods, De La Howe Forest, Station 11, Georgia, July 10, 1942. Diagnosis: As with most species in this family, shelfordi differs principally from its relatives in modifications of the gonopods.
Fig. 4. Cleptoria shelfordi. Left gonopod, posterior view.
Description: Body strongly arched, 58 mm. long and 13 mm. wide; posterior edge of lateral keels slightly overlapping the anterior edge of the ensuing ones; dorsal surface finely coria- ceous.
Color of dorsum light brown (in alcohol) to the base of the lateral keels which are colorless; head generally light brown with the antennae considerably more dilute brown; legs and ventral surfaces colorless.
Gonopods as shown in figure 4.
Sternum between the fourth legs narrow, with two small, high tubercles mesially in contact; fifth sternum wider and



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

with a pair of broader, lower, well separated tubercles; sixth sternum with a pair of small tubercles; seventh sternum with fainter elevations bearing a few stiff, erect setae; sternum im- mediately behind the gonopods with two small, separated clus- ters of erect setse; anterior sterna of segments 9 to 17 usually with a small, faint tubercle on either side behind, adjacent to the leg; posterior sterna with a more prominent tubercle in the same relative position.
Beginning near the middle of the body the first joint of the succeeding legs has a small conic tubercle at the disto-ventral limit; second joint of all legs with the customary spine long and stout.
A remarkable peculiarity of the type is that the eighth seg- ment, which appears normal in other particulars, is without any suggestion of legs.

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

174 Psyche [Sept .-Dec.
Length 36 mm., width 10 mm. Dorsum somewhat flattened, broadly convex, the surface slightly coqiaceous, lateral keels thin with pores on upper surface. First segment with lateral limits extending somewhat further ventrad than in any species of related genera, much exceeding the keels of the ensuing seg- ments.
Gonopods of the form shown in figure 5, a and b with the apical arms crossing each other when at rest. Fig. 5. Stelgipus agrestis. a, Right gonopod, posterior view; b, Right gonopod, mesial view.
Basal joint of legs behind middle of body with a small acute apical tooth below; second joint of all legs with the usual disto- ventral spine well developed.
Sternum between the third legs narrow and occupied by two small, round, contiguous tubercles; fourth sternum wider, with two small conic tubercles slightly separated and bearing one or two stiff setae; ensuing sterna wider and without tubercles; all sterna from segment 4 to the middle of the body with a trans- verse oval area containing a few small setae; from segment 8 caudad the posterior sterna have a small, broadly conic tubercle near each leg, the anterior sterna with smaller tubercles only on segments behind the middle of the body; sterna behind the gonopods slightly narrower than in related genera.

Seven specimens, including three mature males (1 the type) collected under bark of orange trees at Venice, La., February 17, 1944 by Morris Gordon, Division of Foreign Plant Quaran- tines, Bureau of Entomology and Plant Quarantine. a
Diagnosis: The great development of the two median rows of tubercles of the penultimate segment into a backwardly pro- duced lobe that far surpasses the tip of the last segment distin- guishes this milliped of the Cajun country from its Mexican relatives.
Description: Body white or light yellow but the vertex of head and metazonites with what appears to be a light but gen- .
era1 accumulation of dark organic matter adhering to the sur- face; dorsum high and very strongly arched with lateral keels projecting outward almost horizontally from very low on the sides, their outer extremities at the same level as the coxse; length of male 7.5 mm., female 8 mm.
Head with vertex abruptly raised on either side of the median line into a narrow tongue-like elevation rounded in front ad- jacent to the antenna1 socket with its outer limit behind con-

Segment 2 with keels projecting at right angles to the long axis of the body, not produced forward; three lobes on the outer margin but only two lobes on the outer margin of the keels on all segments thereafter except the poriferous ones where the posterior lobe is replaced by the large, slenderly conic, truncated pore process.
Segments with four major dorsal longitudinal series of tuber- cles, three tubercles in each row; the outer row of tubercles on each side less conspicuous than the inner row; small scattered granules present between the large rows of tubercles; keels with- out tubercles or granules. On segments 17 and 18 the outer rows of large tubercles are reduced in size and are almost lacking from segment 19; on segment 18 the two inner rows of tuber- cles are enlarged and also are slightly produced beyond the
