Front femur and tibia slightly flattened beneath, their surfaces not 

 irregular, the tarsus eiliate ; middle femur with regular and convex 

 inferior surface ; the tibia seen from in front with its inferior edge at 

 the basal third strongly dilated and angulate ; tibia three-quarters as 

 long as the tarsus; metatarsus seven-tenths as long as the remaining 

 segments together ; fourth segment about as long as broad ; hind tibia 

 four-fifths as long as the tarsus ; the metatarsus as long as the remain- 

 ing segments united ; the fourth segment slightly longer than broad. 

 Radial cross-vein a little less distant from R^ than is M3+4 from M^ on 

 the borders of the cell R^+r,- 



First segment of the abdomen seen from above deeply concave ; the 

 abdomen closely, rather coarsely punctate at base, sparsely and more 

 minutely at apex ; truncate surface of last segment extensive, the 

 superior processes acute, the inferior small blunt tubercles; process of 

 the third ventral segment with a median 'groove on its summit, ante- 

 riority with 2 blunt teeth. 



Squama with a patch of setae on the outside but with only short, 

 appressed and inconspicuous pubescence within ; the sagitta short and 

 stout, trigonal, the angles sharp, the apex moderately obtuse ; uncus 

 deflexed, contracted just beyond the apex of the sagitta, with a ridge 

 but no barb beneath. 



$. Colored as in the males, except the front is black or mostly so, 

 the mesopleura, metapleura, and propodeum more largely tawny, the 

 mesonotum posteriorly with a medial ferruginous wash. Front and 

 vertex closely, rugosely, behind the ocelli sparsely, punctate ; clypeus 

 very coarsely and deeply and densely punctate ; mesonotum densely 

 punctate on the flattened but not depressed posterior portion, punctu- 

 late but more or less obsoletely so in the middle, and with scattered, 

 coarser punctures ; scutellum with a weak median carina at base, sub- 

 obsoletely punctulate, sides of propodeum sharply mucronate ; abdomen 

 opaque, very densely punctured.
