carina on each side; the tegument between the carinae fuscous, rest of 

 carapace dark brownish to blackish. A paratype from near the type

 cence; face with poorly defined punctures, clypeus not so closely punc- 

 tured as the face, its anterior margin narrowly truncate, slightly refiexed, 

 front and vertex finely sculptured, occiput and cheeks, with indistinctly 

 defined punctures more shining than on the face, postocellar line apparently 

 as long as the ocellocular line but not much more if more than half the

 pronotum partly striate, shining, mesonotum sculptured like the face, 

 mesopleurae shining, sternauli present on the anterior third, mesopleurae 

 divided transversely near the middle by a furrow, the upper half divided 

 longitudinally by a shallow depression that is transversely striate, lower 

 half of mesopleurae and anterior half of upper half polished, scutel more 

 coarsely sculptured than the mesonotum, tegulae and base of wings yel-
