288 (- ). Bkachynus pulchelltjs sp. nov.

 ish-blue; sides of meso- and metasterna and entire abdomen fuscous. An- 

 tennae with joints 3 and 4 almost black. Thorax longer' than wide, the base 

 gradually constricted, its disk more convex and hind angles acute and more 

 distinct than in perplexus. Elytra almost smooth, the humeri distinct.

Vigo and Posey counties; scarce. February 14-April 18. 

 From cordicollis, our only other small species with the third and 

 fourth joints of antenna dark, it differs in the thorax being much 

 narrower and less constricted, and with less prominent hind angles. 

 This is one of the first species to appear in spring and is the only 

 one besides tormentarius which has been taken in the winter months. 

 It occurs in low, sandy localities.

 middle. Elytra but little wider behind, obsoletely costate, nearly or quite 

 covering the abdomen ; humeri evident but narrow. Length 8-9 mm.
