surface otherwise moderately strongly reticulately wrinkled. Propo- 
deujn: rather strongly reticulately wrinkled, except more weakly 
sculptured basad of basal trans-carina. 1st gastric segment: post- 
petiole finely to rather strongly and granularly micro-reticulate but 
becoming smooth and polished apicad, with scattered, small, shallow 
punctures emitting moderately long, not much overlapping setae 
mostly apically and laterally. 2 nd gastric tergite: mat to dully shin- 
ing, finely and granularly micro-reticulate with scattered small to 
medium-sized, mostly superficial punctures emitting long, rather ir- 
regularly spaced setae that average a little to very much shorter 
than their interspaces. G aster: setae of following tergites more or 
less consistently overlapping, much denser than on 2nd. male: 
Color: differs from female as follows: flagellum less definitely brown- 
ish-stained, with a more or less incomplete white annulus on segments 
11 (in part) or 12 to 18 or 19 (basally) ; reddish staining a little 
duller and less extensive; white blotch on clypeus larger and mostly 
fused with white on face; white band of dorsal margin of pronotum 
reaching from opposite end of notaulus only about 2/3 the distance 
to tegula; white on mesopleuron broken up into a large blotch on 
lower 1/2 anteriorly and a smaller, detached blotch in hind-corner; 
apical margin of mesopleuron more dully whitish; no white laterally 
on 1st gastric segment; lateral and apical white bands on tergites 2-4 
narrower, subapical band on 2nd especially narrow and brownish- 
suffused ; fore-coxa black with piceous staining and broadly white 
anteriorly; fore-trochanter whitish below; white blotch on mid-coxa 
much smaller; hind-legs broken off beyond coxa. Length of fore- 
wing: 8.4 mm. Malar Space: 0.7 as long as basal width of mandible. 
Temple: 0.5 as long as eye in dorsal view. G aster: slender, com- 
pressed toward apex, setae about as in female. 
Specific name: Compsa is derived from the Greek adjective 
kompsos t which means “elegant” or “pretty”.
