 Black, shining, elytra and abdomen sparsely pubescent; thorax and legs 



reddish-yellow; antennae dusky, the basal joint paler. Head behind the 

 eyes with numerous fine punctures and short hairs. Elytra together slightly 

 wider than long, coarsely, rather closely and very roughly punctate. Ab- 

 domen as wide at base as elytra, thence strongly tapering to apex, coarsely 

 and rather closely punctate. Length 5-5.5 mm. 



Kosciusko and Putnam counties; scarce. April 17-October 17. 

 Oc- ur beneath vegetable debris close to water. The fifth dorsal ab- 

 dominal siy:ment is often pale at apex.

 Hlark. shining; antenna? piceous. usually paler at base; legs dull yel- 

 low, varying to piceous. Otherwise as in fl.avicollis. Length 4.5-6 mm. 



Throughout the State; frequent, March 2( (-October 31. 



XXVIII. HETEROTHOPS Steph. 1831. (.Gr., "different + eye.") 



Smnll spindle-shaped species having the head with three or four 

 coarse punctures, the front one nearly at middle of inner margin of 

 eye; thorax as in AcylopJiorus, the disk with two punctures on 

 middle of apical half and two smaller ones on apical margin. Males 

 with the sixth abdominal segment emarginate. Two of the three 

 species have lic'Mi taken in Indiana.
