THE CANADIAN ENTOMOLOGIST. 71 NEW NORTH AMERICAN TRYPETID^. BY D. W. COQUILLETT, WASHINGTON, D. C. Trypeta (Acidia) tortile, ii. sp.,?. Wholly yellow except a black dot above each vving ; ovipositor brown; bristles black; scutellum bearing four bristles ; thorax and abdomen shining; ovipositor flat, veiy broad, nearly as long as the last two abdominal segments. Wings hya-line, the anal cell, bases of marginal, sub-marginal, and of the first basal cell, also the apex of the second basal cell, yellow ; a black spot on furca-tion of the second and third veins, and one on lower half of vein at apex of anal cell ; a brown band commences on costa between apices of auxiliary and of first vein, and extends to the discal cell, going over the small cross-vein and continuing as a yellowish streak into the discal cell ; a second brown band commences on the costa between apices of the first and second veins, and crosses the wing, passing over the posterior cross-vein, and near its terminus sending a spur into the third posterior cell ; apex of wing from slightly beforeapex of the second vein to beyond tip of fourth vein, brown ; first and third veins bristly. Length, 5 mm. Washington (O. B. Johnson). A single specimen. The colouring of the wings somewhat resembles Figure 9, Plate X., of Loew's " Monographs," Part III., but the fifth vein is not bordered with brown ; the brown at the apex of the wing is separated at the costa from the preceding cross-band ; the band crossing the discal cell is scarcely perceptible, etc. Trypeta (Rhagoletis) /ormosa, n. sp., ^ $ . Black, the head and its appendages (except the ocellar tubercle and occiput), a line reaching from humeri to each wing, scutellum except the sides at base, halteres and legs, yellowish ; thorax and scutellum sub-opaque, the abdomen shin-ing ; proboscis slender, geniculate, the apical half bent downward ; sides of front and scutellum each bearing four bristles ; ovipositor compressed, slightly exceeding the last four abdominal segments in length ; wings hyaline, marked with three cross-bands and two spots of brown, extreme base of wing smoky ; the first cross-band begins at first vein and extends over veins at bases of discal and third posterior cells, stopping near mid-dle of axillary cell where it is much widened ; the second band begins on costa between apices of auxiliary and first veins and extends over small cross-vein, and through the discal and third posterior cells to the wing margin, its greatest width occurring at the fifth vein ; a brown costal spot between apices of first and second veins, extending across marginal and
