extending back to basal angles of hemelytra; base of scutellum 



poorly defined (p. 546) Pithanus 



Antennal segment i, in length, greater than width of vertex; pro- 

 notum extending back to basal angles of hemelytra; hemelytra

 middle of abdomen (p. 546) Mimoceps 



3. Head strongly exserted, eyes placed near middle and thus far 



removed from anterior margin of pronotum (p. 547) Collaria

 pronotum or nearly so 4 



4. Pronotum impunctate or nearly so 5

glabrous, at most with very short pubescence 6 



Antennal segments thickly covered with erect black hairs; body
