Psyche 
[October 
upper row forming a nearly straight line, its bristles equidistant 
with the lateral one close to the eye; ocellar tubercle and median 
frontal groove distinct. Antennae small, round; arista strongly 
pubescent, one-fourth longer than the head height. Palpi rather 
large, with strong marginal bristles near tips. Cheeks each 
with three strong downwardly directed macrochaetae and a series 
of smaller bristles extending to the base of the antenna. Meso- 
notum rather long, highly convex; one pair of dorsocentral bris- 
tles set as far apart as the lateral corners of the scutellum. 
Scutellum nearly twice as broad as long, with two marginal 
bristles, but no trace of a second pair. Propleura with a tuft of 
small bristles above, several more below near the coxa and a 
series of minute ones between, along its posterior margin. Meso- 
pleura entirely bare. Abdomen with some short hairs at the 
sides of the second and third segments, but without distinct 
lateral tufts; first three tergites completely chitinized; fourth 
with a short basal chitinized band and a very narrow median 
stalk-like chitinized strip, but with the sides entirely mem- 
branous; segments five and six chitinized as usual (these may be 
the sixth and seventh if two segments are included in the struc- 
ture described above as the fourth, which I think may possibly 
be the case); next segment short and very narrow, pale; last 
narrow, tubular, black. Legs rather slender; fore tarsi slightly, 
but distinctly thickened, the second and following joints but 
little more than twice as long as broad. Cilia of hind tibia in a 
single row, rather delicate, the larger ones near the middle of 
the tibia about two thirds as long as its width; internally at the 
tip the hind tibia bears three comb-like transverse rows of minute 
bristles. Costa extending to distinctly beyond the middle of the 
wing, its bristles long and rather closely placed; first section 
barel}^ longer than the second; third nearly half as long as the 
second (22:19:9); fork of third vein not very acute, the cell 
rather large; fourth vein strongly curved near base, more weakly 
so beyond, recurved at the extreme base; fifth nearly straight; 
sixth weakly bisinuate, seventh faintly curved. 
Type from Taihorin, Formosa, July, 1911 (Sauter). 
This is a very distinct species, resembling the Formosan A. 
curtifrons Brues, from which it differs by the long costal cilia.
