FAMILY L. — SCABABiEIMS. 



broadly rounded, hind angles rounded, surface finely and sparsely punc- 

 tate. Elytra with rows of very fine, feebly impressed punctures ; the side 

 margins in female often thickened near middle. Cylindrical elevation of 

 prosternum behind the front coxre distinctly visible when viewed from the 

 front. Length 12-14.5 mm. 



Vigo, Putnam and Posey counties; scarce. May 12-July 30. 



1849 (5862). Cyclocephala villosa Burin., Handb. Ent., V, 1856, 54. 



Resembles the preceding but more con- 

 vex. Color pale dull yellow, front pic- 

 eous ; clypeus reddish-yellow. Thorax as 

 in immaculata. Elytra more coarsely and 

 roughly punctate, the rows of punctures 

 ill-defined ; surface viewed from side finely 

 and sparsely pubescent. Prosternal ele- 

 vation scarcely visible, when viewed from 

 the front. Length 11-14 mm. (Fig. 408.) 



Marion and Putnam counties; 

 scarce. July 1-July 30. The longer 

 antennal club of male, paler color and 

 more roughly punctured elytra distinguish this species. It and the 

 preceding fly after dusk and are attracted by light, being seldom 

 seen by day.

XXX. Dyscinetus Harold. 1869. (Gr., "bad + moving. ") 



The characters of this genus have been sufficiently set forth in 

 the key and the remarks under Cyclocephala. One of the two 

 known North American species occurs in the State.* 



1850 (5868). Dyscinetus teachypygus Burm., Handb. Ent., V, 1856, 79. 



Elongate-oblong. Piceous-black, shining; antennae and legs dark red- 

 dish-brown. Clypeus almost truncate in front, sides diverging, surface 

 sparsely, shallowly and rather finely, front more coarsely, punctate. Tho- 

 rax one-half wider than long, sides feebly curved, hind angles rounded, 

 front ones acute ; surface coarsely, sparsely and irregularly punctate. Ely- 

 tra each with four feebly raised lines, these with a row of fine, variolate 

 punctures each side ; intervals broader, with three or four very irregular 

 rows of similar punctures. Length 15-18 mm. 



Occurs beneath rubbish along the sandy shores of lakes and 

 larger streams throughout the State; frequent. April 8-October 



^Dyscinetus barbata Fab., Mant. Ins., I, 1787. 10. 



Elongate-oval. Uniform mahogany-brown, shining. Head and thorax very finely and very sparsely punc- 

 tate, the latter otherwise as in irachypygus. Elytra minutely alutaceous, wholly without punctures. Length 

 18 mm. 



This is a West India species, one specimen of which was taken by Max Ellis at porch light on the State For- 

 estry Reservation near Henry ville, Clark County. It was evidently introduced by commerce, and as only a single 

 specimen was taken it is not included in the regular list. Identified for me by Frederick Blanchard.
