AMERICAN DIPTERA. 339 



tion of the dorsum, well outside of and parallel to the median 

 stripe. 



So far as I know this is the only specimen of this species 

 recorded. Both antennas had lost the third segment and style 

 before being sent to me for study. 



CALLINICUS. 



Callinicus Loew, Cent., X, 32, 1872. 



Callinicus is close to Deromyia in form of body, but is easily 

 separated from it by the absence of the tibial spurs. Head 

 moderately broad, face broad, the whole slightly convex; 

 mystax of stiff hairs extending up to the antennas, longer near 

 the oral margin. Antennas of moderate length, not approx- 

 imate, the basal segments short, cylindrical, the first stouter 

 and a little longer than the second, both well clothed with 

 bristles and hair; third segment longer than the first two 

 taken together, of nearly equal width throughout; style short, 

 distinct, stout at base, tapering to a point, apparently two- 

 jointed. Thorax moderately convex, with short hair on the 

 dorsum and with well-developed bristles on the posterior mar- 

 gin of the scutellum, on the posterior callosities, and forming 

 a double row over the base of the wing; there are also a 

 varying number of scattered shorter bristles on the dorsum 

 before the scutellum. Abdomen stout, moderately convex, 

 toward the tip but little attenuated. Legs rather long, strong, 

 lightly pilose ; the hind tibiae toward the apex not thicker. 

 The fore femora on the hind side above, the middle pair on 

 the anterior side and again on the upper posterior side at the 

 tip, and the hind pair on the anterior side above and at tip, 

 with scattering bristles; the tibiae and tarsi with bristles as 

 usual; the terminal bristles of the middle tibiae on the inner 

 side are directed inward, while in all the other genera of the 

 Dasypogoninas except Chrysoceria, they are directed more 

 downward ; claws well developed, pulvilli normal. All the sub- 

 marginal and posterior cells wide open; the wings when folded 

 nearly equaling the abdomen in length. 



Type. — Callinicus calcaneus Loew.
