punctures and wrinkles; surface otherwise with rather coarse reticu- 
late wrinkling. Wing-Venation: radial cell 3.8-4. 1 times as long as 
wide ; areolet large, intercubiti strongly convergent above, 2nd abscissa 
of radius 0.7-0.8 times as long as 1st intercubitus; 2nd recurrent 
slightly inclivous or nearly vertical, gently and almost evenly out- 
curved or more strongly curved on upper ^ ; disco-cubitus broadly 
angled, without or with a short to moderately long ramellus ; nervulus 
a little antefurcal to interstitial; mediella gently arched throughout; 
upper part of nervellus 1.6- 1.7 times as long as lower; axillus close 
to hind-margin of wing. Propodeum: short and high, faces sub- 
equal : basal moderately sloping behind, apical almost vertically 
declivous; spiracle 1 .2-1.3 times as long as wide; basal trans-carina 
sharp throughout, in places a little irregular, strongest and forming 
low-crescentic or subcuneate cristae laterad; apical trans-carina de- 
tectable but very irregular, especially medially; cristae of apical 
trans-carina exceptionally large and strongly projecting ligulate; 
median longitudinal carinae vague or weak and irregular, areola 
definitely wider than long in position ; lateral longitudinal carinae 
irregularly traceable basad, becoming stronger between trans-carinae 
and, especially, as they continue onto cristae behind ; surface strongly 
reticulately wrinkled, a little more weakly sculptured basad of basal 
trans-carina. 1st gastric segment: no expansion at base of petiole; 
postpetiole moderately broadened, 1.1-1.3 times as wide apically as 
long from spiracle to apex ; ventro-lateral carina traceable throughout, 
strongest on postpetiole ; dorso-lateral carina traceable throughout, 
sharp on postpetiole ; dorsal carinae finely detectable on most of petiole 
and base of postpetiole, strongest apiead ; surface of postpetiole smooth 
and shining with fine, rather weak micro-reticulation which fades out 
near apex and small, obscure, scattered punctures that emit moderately 
short, mostly well-separated setae. 2 nd gastric tergite : a little dully 
shining, with distinct fine and weakly granular micro-reticulation 
and numerous small, very obscure punctures that emit short, largely 
widely-separated setae which may become somewhat longer and 
denser, but not extensively overlapping, laterad and apiead. G aster : 
rather elongate fusiform ; setae of following tergites may be generally 
somewhat denser than those on 2nd. Ovipositor : sheathed portion 
0.3 times as long as fore-wing; straight, moderately slender, com- 
pressed; nodus low, with a rather large, shallow notch; dorsal valve 
with a long, nearly direct to slightly concave taper between notch 
and apex; ventral valve with fine, well-spaced oblique ridges on tip; 
tip 0.16-0.19 times as high at notch as long from notch to apex. 
Male: differs from female as follows: Color: no pale band on
