 1844, 114. 



Oblong-oval, convex. Pic-eons, feebly shining; antenna ami legs dull 

 vellow elytra each with about ten sinuous, more or less connected yellow- 

 sh Zk o'ne of which is a reverse, crescent or Cose t ; , su arc , n ,,

 ^al in whTth; surface deeply and rather coarsely and elcely pmrctat* 

 Elytra two-thirds longer than wide, more coarsely and sparsely punctate

Laporte end Lawrence counties; rare. June 10-June 14. Oc- 

 curs on decaying twigs. Casey's type of A. maoulata^ from In- 

 diana-Levette collection-without definite locality. It is probably 

 of not more than varietal rank. 



Incolia longipennis Casey, elongate, parallel, blackish, sides of 

 thorax and streak on elytra paler, length 3.8 mm., was described as 

 being doubtfully from Indiana.
