Figures 2, 25, 27, 30 
Vertex entirely black; rostrum reddish brown, with 
weakly defined grayish stripe on each side ; thorax reddish 
brown laterally, entirely black dorsally; the 1st to 6th 
abdominal segments black dorsally and ventrally, last few 
abdominal segments of male reddish brown, the hind 
border of the third tergite of male prolonged into a small 
semicircular process, 6th abdominal segment furnished 
with a single anal horn, reddish brown in color. Fore 
wing : length, 14 mm. ; width, 3.55 mm. ; membrane light 
grayish brown, without markings except for a slight sus- 
picion of grayish brown at the apex ; pterostigma promi- 
nent, indicated by grayish brown color ; the wing apex ob- 
tuse, broader than in the preceding species. Hind wing : 
length, 13 mm. ; width, 3.5 mm. ; similar to fore wing, c? 
genitalia : genital bulb rounded, coxopodites long ; harpa- 
gones short and stout, the outer margin smoothly curved, 
the inner margin with a greatly reduced median tooth 
which cannot be seen from ventral view and a large basal 
concave area ; hypandrium inconspicuous ; hypovalvse 
rather straight, reaching nearly to the base of the harpa- 
gones ; parameres simple and stout, usually not extending 
beyond the tips of coxopodites, each consisting of a single 
spindle-shaped stalk, formed by the outer strongly sclero- 
tized part; the distal inner margins of parameres fur- 
nished with a series of long barbs ; preepiproct slightly 
narrow towards the apex, with a wide U-shaped distal 
incision ; sedeagus with small lateral processes and a pair 
of long apical processes, the inner margins of the latter 
nearly parallel to each other.

Holotype (<?) : Mt. Taipai, Shensi; July 14, 1943; 
Chuan Lung Lee; in my own collection. 
This species belongs to the centralis group, having the 
same wing marking as the preceding species, but the body 
color and the structure of male genitalia, especially the 
short parameres, make its recognition easy.
