ing metasternum, the latter never grooved for the reception of the 

 legs. The contractile or "doubling-under" power is therefore 

 much less than in the tribes which follow. Bight genera are either 

 represented in the collection at hand or should occur in the State. 



KET TO THE IXDIANA GENEHA OF ANOBIIJSII. 



n. Front coxte contiguous or narrowly separated (except in OUgomerus 



sericans) ; process of prosteruum usually ending in a sharp point. 



&. Last joint of both labial and maxillary palpi elongate, spindle-shaped ; 



antennjE usually 10-jointed. V. Oligomekds. 



66. Last joint of maxillary palpi parallel and obliquely truncate ; last 



joint of labial paljii broadly triangular: antennse 11-jointed. 



VI. Sitodbepa. 

 on. Front ooxte distinctly or even widely separated ; iirostemal process mth 

 parallel sides ; antenna; usually received between the coxie in repose. 

 c. Antennre nut serrate, joints 9 to 11 long. 

 d. Tarsal claws with a broad basal tooth ; form oblong, densely pu- 

 bescent and ornamented with tufts of erect hairs. 



VII. Teichodesma. 

 (Id. Claws not toothed. 



c. Ventral segments free, sutures distinct; tarsi narrow. 



/. Metasternum deeply excavated in front. Anobiuii. 



//. Metasternum not deeply excavated in front, at most a little 



concave. 



g. Third ventral segment short; tibite not produced on the outer 



side at apex. VIII. Hadbobeegmus. 



gg. Third ventral segment long; tibiae acutely produced on the 



outer side at apex. Micbobeegma. 



CO. Ventral segments firmly united, their sutures, except the first 



faint or obliterated at middle; tarsi stouter and broader.

Pi'ont and middle coxffi without an intervening cavity for the 

 reception of the antennna ; first, third and fourth ventral segments 

 nearly eciual and shorter than second and fifth. One species has 

 been taken in Indiana, while another may occur.
