A REVIEW OF THE AMERICAN SPECIES OF THE GENUS PALLOFTERA.
BY CHARLES W. JOHNSON,
Boston Society of Natural History, Boston, Mass. In a recent study of the species of Palloptera, including the type of P. jucunda Loew, in the Museum of Comparative Zoology, it seemed that some discrepancies existed that should be corrected. Prior to Dr. A. L. Melander's paper1 no figures accompanied the - original descriptions, and this may account for some of the errors. A comparison of the figure of the wing of P. jucunda by Melander with the type shows a marked difference (although the series of P. juczindn shows some variation) and is apt to be misleading, å´
especially since there is a much larger species having practically the same wing pattern as that figured for P. jucunda. The wing figured, as P. jucunda in Williston's Manual of North American Diptera, 3d edition, page 80, is P. superba. I have been unable to find an American species agreeing with the European P. arcuata Meig. It was determined by Coquillett and recorded from Mt. Washington, N. H., by Mrs. Annie T. Slosson, but none of the specimens I have collected there and at Mt. Desert, Me., agree with that species. Submitting a sketch of the wing of a specimen taken at Base Station, Mt. Washington, to Mrs. Slossom, she writes : "I have looked, up the unique specimen of P. arcuata. It is in poor condition, abdomen missing, but wings perfect. They are exactly like your figure, clouded at the tip, not extending along the costa."

Thorax and scutellum yellow, shining, with fine brown hairs, one prominent dorso-central and four large mar- ginal scutellar bristles. Abdomen yellow, third, fourth, and fifth segments brown. Legs including the coxse light yellow, halteres yellow. Wings hyaline, first veins but slightly clouded, tip of wing and posterior cross-vein broadly clouded with brown. Length, male 4.5 mm., female, including ovipositor, 5' mm. -
Seven specimens.
Holotype, Bar Harbor, Me., Aug. 10, 1920 (C. W. J.). Al-lotype, Northeast Harbor, Me., July 1, 1909 (Dr. C. S. Minot), and two paratypes, Bar Harbor, Aug. 15, and Base Station, Mt. Washington, N. H., Aug. 15, 1916 (C. W. J.), in the collection of the Boston Society of Natural History. Para- types are also in the Museum of Comparative zoology; U. S.Na- tional Mnseum, Mrs. Slosson's and the author's collections. Palloptera jucunda Loew (Fig. 2).
In addition to the type locality, Sitka, Alaska, and the locali- ties recorded by Melander, I have specimens before me from Parro- quet Island, Labrador, July 21, 1887 (S. Henshaw), Mus. Comp. Z061.; Midvale, Montana, Aug. 25 (0. E. Brown) ; Logan, Utah, Sept. 1915 (H. B. Hagan). Cranbrook, B. C., ~&t. 12 (C. Garrett).
Palloptera albertensis sp. nov. (Pig. 3). Front dark yellow, opaque, orbits, face and occiput light yel- low, antennae yellow (third joint wanting). Thorax and scutel-
lum yellow, subshining, with macrochaetse similar to P. jucunda. Abdomen yellow, with a narrow black dorsal line expanding to- ward .the top, ovipositor brown, forming about two-fifths the length of the entire abdomen.
Legs and halteres yellow. Wings, near the end of the first vein and base of the costal margin, yellowish. Length, including the ovipostor, 7 mm.

figured by Melander resembles this more than it does the typical jucunda, yet there are variations of the latter in which the wing markings approach this species. The brown costal margin has a ,
spot of slightly lighter shade just beyond the tip of the first vein, scarcely noticeable to the naked eye. In jucunda this spot in the costal margin is usually much larger and hyaline. Pall~pt~era similis Johnson (Fig. 4)..
Since . describing this species from Fort Kent, Me. (Psyche, 1910, vol. 17, p. 2.33), I have taken it on the carriage road, Mt. Washington, N. H., at about 2,500 feet, July 24, 1915. The wing pattern resembles that d P. setosa Melander.
