content: Chrysops bishoppi, new species (Plate XXXI, fig. 26; Plate XXXVII, fig. 107) Color. Yellow with black abdominal pattern ; wing picture dilute. Size. Length,8mm.to10mm. Structural and Color Characters. Female: Vertex, frons and sides of genae yellow pollinose; frontal callus black; frontoclypeus and oral margins of genae denuded yellow ; the pits on each side of the frontoclypeus and a tiny spot on the outer side of the oral margins of the genae, fuscous. Palpi yellow. Antennae variable; usually the scape and pedicel yellow with their outer and upper surfaces black, black pubescent; flagellum black, brown or yellowish at thebase. Dorsum of thorax and scutellum green-gray pollinose, sparsely yellow pubescent, the former with three fuscous stripes; pleurae and venter yellowish-gray pollinose, the former with yellow pile. Dorsum of abdomen yellow; the first tergite with a black quadrate posteriorly emarginate spot beneath the scutellum, second tergite with a median black geminate figure, not attaining the posterior margin; tergites III and IV with a more or less double black geminate figure confined to the anterior half of the tergites; tergites V and VI more or less corresponding to the preceding, except the pattern seems to be composed of two posteriorly emarginate black spots confined to the anterior margins of the tergites; remaining tergite -black with a yellow hind margin. Venter of abdomen yellow with a small median black spot on segment I which may connect with another on segment II ; segments III to V usually with a trace of black in the center confined to the anterior margins; remaining segments black with yellow hindmargins. Halteresbrown. Wings as figured; the picture very dilute brown; usually the in- fuscation of cell R is interrupted by hyaline before the apex. Legs orange-yellow; the joints, apical portion of front tibiae and entire tarsi, apices of middle and hind tarsi, fuscous. Male: Quite similar to the female, easily associated, exhibiting the usual sex differences and more melanism. The black figures of the abdominal dorsum are more extensive, the median geminate spot on tergite II thicker, in one specimen a black spot is present on each side. Cell 2d M of the wing exhibits about the same degree of infuscation as R. Legs like the female, but with more fuscous as follows: Dominant on the front coxae, large basal portions of front and hind femora, and ex- treme base of middle femora. Comparative Notes. Separated from C. furcata Walker by the dilute wing picture, different abdominal pattern, absence of a black spot on each side of the frontoclypeus, and greater predominance of yellow on the abdomen and legs. The black frontal callus and abdominal picture should at once distinguish this species from C. coloradensis Bigot. Remarks. Described from reared specimens variously determined as C. coloradensis Bigot and C. furcata Walker. Type Data. Holotype: Female, Topaz, California, June 7, 1919, Bishopp, No. 9916.
