projecting over clypeus at internal angles with a small hook; clypeus strong, 

 swollen, roughly three-Iobed, the central lobe the largest, tips strongly hirsute. 



Pronotuni densely and coarsely punctate; anterior surface slightly convex, 

 light yellow with numerous brown markings, sparingly pubescent with rather 

 long hairs; suprahumeral horns projecting outward and very slightly back- 

 ward; lateral surfaces not pubescent, brown with two transverse light bands, 

 the anterior broad and irregular in about center, the posterior narrower and 

 regular just before apex of j^osterior process; posterior process gradually acute, 

 extending beyond internal angles of tegmina. 



Tegmina hyaline, tips sriioky, bases opaque and lightly punctate ; five apical 

 and three discoidal cells. Undersurface of body very dark brown. Femora 

 dark brown above; tibise and tarsi ferruginous. 



Length, 9 mm.; width between humeral horns, 5.5 mm. 



Internal male genitalia. Styles stout, varying much in the length 

 of the cephalic part which, at its greatest length, is shorter than the 

 part caudad of the connective, the sharply pointed caudal portion 

 bearing two rows of long hairs; connective longitudinally keeled, 

 when open nearly twice as long as wide, base concave, apex nar- 

 rowed but obtuse; oedagus, viewed laterally, much as in Ceresa 

 bubalus, but with dorsal process usually more pointed apically and 

 the ventral process distinctly narrower and more acute apically. 



Distribution: Van Duzee reports this species from Nova Scotia, 

 Ontario, New York, New Jersey, Pennsylvania, Maryland, North 

 Carohna, Ohio, lUinois, Iowa, Kansas, Missouri, Dakota, Colorado, 

 Texas, New Mexico and Montana. It is therefore one of our most 

 widely distributed species. In Kansas specimens have been taken in 

 Douglas, Miami, Neosho, Bourbon, Pottawatomie, Riley, Shawnee 

 and Saline counties. 



Hosts: The usual host for this species is elderberry. Funkhouser 

 gives the following additional hosts: Locust, oak, sycamore, sweet 

 clover, blackberry and butternut.

The following is the original description: 



A little smaller and paler than diceros, to which it is closely allied. Prono- 

 tum as in diceros, but with the suprahumeral horns more acute and recurved 

 and tipped with black, and the apex longer and more slender. Face, front 

 and superior surface of the pronotum greenish- or yellowish-white with scarcely 

 a trace of the maculations found in dicero^i; apex of the head less produced, 

 the tylus scarcely longer than the cheeks. Sides of the pronotum paler, fer- 

 ruginous, becoming somewhat fuscous posteriorly, irrorate with paler and 

 marked with a pale marginal line and sometimes with an oblique median 

 vitta; protracted apex whitish with a black tip and ferruginous median vitta; 

 outer surface of the suprahumerals dark ferruginous, differentiated from the
