220 HYMENOPTERA. 



yellow ; middle of mesothorax with smaller punctures than lateral 

 fields ; base of metathorax dullish, except a narrow basal band crossed 

 by ridges , tegulse small, ferruginous; wings dusky, nervures and 

 stigma (which is narrow) ferruginous ; legs largely dark chestnut-red; 

 the anterior knees, spot near apex of anterior femora behind, basal 

 streak on their tibia, large basal mark on hind tibiae, and most of hind 

 basitarsus yellow ; hind legs with much silver-white hair ; abdomen 

 green, constricted laterally at the sutures ; sides of apical segment 

 minutely denticulate ; ventral hair white, except a minute tuft of yel- 

 low at extreme apex. 



Related to C. nasalis Friese, but easily separated by the 

 face-markings and the sculpture of the mesothorax. The 

 eyes, in the dry state, are light ferruginous, those of nasalis 

 are black.

 with ochreous dorsally, with black bristles intermixed on scutellum and 

 posterior half of mesothorax ; mandibles black, with a faint reddish

 the followi ig three united ; flagellum, especially the apical half, dark 

 ferruginous beneath ; third antennal joint a little shorter than fourth ; 

 tegulse moderate, rufotestaceous ; wings yellowish, the apical margins 

 broadly and conspicuously infuscated ; b. n. meeting t. m. ; second 

 s. m. square, receiving first r. n. a little beyond the middle ; third s. m. 

 longer than first ; legs black with light yellowish hair ; middle femora 

 with a large ferruginous patch in front ; hind femora red, clouded 

 with black apically ; hind tibiae red ; hair on inner side of hind basi- 

 tarsus largely black or nearly so, but partly red ; spurs red ; abdomen

 and bright warm yellowish-ferruginous ; basal parts of the segments 

 densely punctured and minutely tuberculate ; fifth segment and apex 

 with black hair, but red at sides of fifth ; apical plate very narrow ;
