OSBORN AND BALL STUDIES OF NORTH AMERICAN JASSOIDEA. 59 



a narrow light one and two lateral longitudinal lines reddish- fuscous. 

 Elytra with the first sector as far as the first fork and the veins on 

 clavus broadly light, interrupted on the outer claval veins before the 

 tip, remainder of nervures, the claval suture, the internal areas on 

 clavus and a more or less definite saddle extending across the back 

 between the apices of the two claval nervures, brownish-fuscous. The 

 color is subject to great variation but the two round spots on the vertex 

 persist in almost black forms. 



Genitalia: V, ultimate ventral segment twice wider than long, the 

 posterior margin very slightly sinuate either side of a shallow median 

 notch ; p\ gofers short, broad, scarcely twice longer than width of base. 

 d^, valve short, truncate ; plates broad, half longer than wide, trun- 

 cate at apex, the bases enclosed by the inflated p) gofers whose tips, 

 slightly exceeding the plates, are thickly set with coarse hairs. 



This is a widely distributed species. Specimens are at hand from 

 Ont., N. Y., D. C, Ky., Ala , Miss., la., Kan., Neb., VVyo., Colo., 

 Arizona, Cal., and Vera Cruz, .VI ex. 



The larvae somewhat resemble the adult in form ; very short and 

 plump, head slightly wider than thorax, wing pads flaring, in the pupae 

 reaching the fourth abdominal segment, abdomen short, plump, the tip 

 elevated so that the visible part of each segment is narrowest above. 



Color: Creamy-white with heavy fuscous spots and bands. Vertex 

 with the two round spots and median band as in adult, the markings 

 next eye heavier. Face with the sutures and a few arcs on the front 

 fuscous as in adult, thorax with a narrow median light line between 

 two broader dark ones that expand on the anterior margin of each 

 segment, an irregular dark blotch behind each eye extending as a band 

 back to the inner angle of the wing pad, then obliquely outward along 

 the inner margin, a pair of narrow wedge-shaped lines between these 

 and the median one on the posterior segment, an oblique line on the 

 wing pad and a marginal line on the outer and posterior margin, 

 brownish-fuscous. Each abdominal segment with a broad brownish 

 dark band on the anterior margin, venter light. Length of pupje 

 about 2 mm.
