tween bases of antennae, emarginate below; vertex with an 
anterior row of three brown spots, middle row of two black 
marks connected by a line, and a posterior row of three 
brown spots. Last segment of labial palpi short, slender, 
curved, fuscous. Antennae short, heavily clavate; scape 
pale with apical fuscous ring; pedicel dark; flagellum 23- 
24 segmented, the first two or three segments more or less 
fused, shiny-fuscous basally, reddish brown in middle; a 
dark band at base of club, club yellow-buff. 
Pronotum pale, a single dark band each side, narrower 
in front of furrow, often interrupted at furrow. Scutelli 
pale with bilobed anterior brown spot and thin median 
posterior black line. Coxae with basal and preapical brown 
spots, connected on mid and hind coxae. Femora pale, an 
apical dark stripe on posterior side of fore-femur, anterior 
side of mid and hind femora. Fore and mid tibiae with sub- 
basal and preapical dark bands, hind tibiae pale. Tarso- 
meres pale with narrow apical dark bands. 
Abdomen ( $ ) : brown, first tergite dark, second with 
narrow pale band and a pair of large posterior pale spots, 
third and fourth tergites with paired basal, intermediate, 
and apical spots, remaining segments with basal and apical 
spots only. Gonarcus and parameres (Figures 11, 12). 
Ectoprocts short, slightly produced posteriad below. ( 2 ) : 
tergites dark with a pair of apical pale spots on each. 
Many prominent setae on thorax, coxae, and femora. 
Most tibial setae black. Abdominal setae white, black on 
ectoprocts and terminal segments of female. 
Wings: longitudinal veins pale, interrupted with dark 
at intersections of cross veins. Cross veins almost all dark, 
the membrane beside them bordered with dark, giving an 
effect of uniformly distributed short transverse brown 
dashes over wing; somewhat paler on hind wing.
