 vex. Color pale dull yellow, front pic-

 in imtnaculatu. Elytra mure coarsely and

 Fig. 408. < 3. (After Forbes.) antennal club of male, paler color and 

 more roughly punetm-ed elytra distinguish this species. It and the

 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 Cycloccphala. One of the two 

 known North American species occurs in the State.* 



1850 (5868). DYSCINETUS TRACHYPYGUS 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.

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



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



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

 tate, the latter otherwise as in trachypygits. Elytra minutely iilutaceous, 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 Henryvillc, 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.
