lute il a separate species. These differences, which will sufficiently describe 

 it, arc as follows : The margins of the vertex do not connect so closely in 

 front. The median carina of the pronotum is higher and more rounded on 

 top, the southern specimens having it more elevated than the northern ; the 

 angle of the anterior margin less obtuse and advanced farther upon the 

 occiput ; tlie posterior angle decidedly acute, and somewhat prolonged. 



Color. — Thorax generally, though not always, darker than in the former 

 species ; in some specimens there are two yellow dots on the middle of the 

 sides of the pronotum, one above the other, and the front and hind margins 

 are dotted with olive, but these markings are not uniform. The dark ray 

 of the wings, near the front margin, is not more than half as long as in the 

 former species, extending but one-third the distance to the base ; this is 

 remarkably uniform. The posterior femora generally have two oblique dull- 

 yellowish bands on the exterior face, and also a paler and more distinct ring 

 near the apex. 



Dimensions. — Not very uniform. 9 Length, 1.12 to 1.25 inches; elytra, 

 1 to 1.05 inches ; 3 Length, 1 to 1.12 inches.

CE. carinata, Scudd., is very closely allied to this ; and although I have 

 described it as a distinct species on the authority of Dr. Scudder, yet I do 

 not think they are different.

Closely allied to and scarcely distinct from CE. xanthoptera, Burm. 

 Face, seen from the side, slightly arcuate ; frontal costa but slightly sulcate 

 on lower half; sides parallel. Median carina cristate, sharp, arcuate, entire; 

 lateral carinte nearly obsolete ; anterior margin at the middle jirojecting 

 slightly on the occiput; apex acute-angled. Elytra and wings passing the 

 al)domen. Posterior femora passing the abdomen in the male. 



Color. — Head blackish, profusely streaked, and spotted with dull bluish- 

 white ; frontal costa and upper half of the clypeiis edged with whitish ; 

 palpi blackish, the joints tipped with luteous. Pronotum dull dark-brown 

 with a short pale streak extending from the lower edge of the eye. Basal 

 third of the elytra dark-brownish fuscous; rest an ashy-brown, profusely and
