 differing in having the scutellum armed behind with a more emar- 

 ginate plate, the plate bilobed and brownish, in having decidedly 

 shorter antennal scapes which do not reach to the cephalic ocellus, 

 the scrobicular cavity terminating before that ocellus at a point 

 nearly the diameter of the ocellus away (in Tumidicoxa the cephalic 

 ocellus touches the apex of the scrobicular cavity), in being generally 

 smaller in stature and in having the posterior femora beneath armed 

 with flve to six moderately large subequal or unequal teeth followed 

 by three minute ones near the apex and close together. Scape 

 ringed or marked with whitish or yellowish white ; the funicle joints 

 are shorter, after the third, wider than long; club obtusely pointed 

 or eise subtruncate and sometimes longer than wide. Vertex some- 

 what broader. Species black, non-metallic, marked with yellow or
