FAMILY XXXVII. ELATEKIDJE. 



about three inches in length, subdepressed, and has a row of pale 

 yellow spots along middle of back and another each side. In the 

 dark these glow very brilliantly with a greenish-yellow phosphores- 

 cent light. Henshaw claims that this is not the larva of M. piceus. 

 but that of a species of PJiengodes.

Resembles piceus in form and structure; differs mainly by characters 

 given in key. The thorax is proportionally shorter, being as broad as long 

 and is somewhat more coarsely punctured. Length 22-26 mm. 



Vigo and Parke counties ; rare. June 12- -June 17. 



1472 (4517). Melanactes puncticollis Lee, Proc. Phil. Acad. Nat. Sci., 



VI, 1852, 68. 



Elongate, rather slender. Black, shining. Thorax longer than wide, 

 somewhat narrowed in front, slightly rounded on sides, which are less 

 strongly margined than in the two preceding species ; disk rather finely and 

 sparsely punctured, more densely on the sides ; hind angles slightly di- 

 vergent. Elytral intervals subconvex, finely and rather densely pmietu- 

 late. Length 18-21 mm. 



Marion, Vigo and Knox counties ; scarce. May 23-June 25. Oc- 

 curs beneath rubbish. 



1473 (4518). Melanactes consors Lee, Trans. Amer. Phil. Soc, X, 1853, 



495. 



Elongate, robust. Black, not very shining. Thorax not longer than 

 wide, as wide at middle as at hind angles, more convex than in any of the 

 preceding species ; sides broadly rounded, strongly margined ; disk densely 

 and coarsely punctured, median dorsal line not distinct, somewhat smooth. 

 Elytra slightly narrower than thorax, more obtusely rounded at apex than 

 in any except piceus; strife distinctly punctured; intervals slightly convex, 

 finely punctulate, transversely wrinkled. Length 23 mm. 



Vigo County ; rare. June 19. A single specimen taken from a 

 blackberry bush. Described from Nebraska. 



Subfamily III. PEROTHOPINAE. 



In this subfamily the antenna? are well separated at base and 

 arise from small pits beneath well-marked frontal ridges, at a dis- 

 tance in front of the eyes ; the mouth is inferior ; labrum transverse, 

 curved in front, closely united with the clypeus ; presternum slightly 

 lobed in front, the spine very short ; front coxa? small, globular, 

 without trochantin ; middle coxa? oval with a small trochantin ; hind 

 coxa? transverse, the plates broadly dilated on the inner side ; tarsal 

 claws with comb-like teeth. The subfamily is represented by the 

 single genus :
