■ 



Elongate, narrow, subcylindrical, opaque above, black, the prothorax usually with a stripe along the sides 

 (sometimes extending inwards and leaving the base and a median vitta black, sometimes reduced to a 

 small spot), and the elytra each with a very broad vitta on the outer part of the disc (leaving the suture 

 broadly, and the lower margin very narrowly, black, the sutural stripe often more or less sinuate 

 externally or quadrangularly dilated at about the middle), sanguineous or rufous. Eostrum ( $ ) 

 gradually curved from the base, moderately stout, shorter than the prothorax, somewhat closely punctate 

 to near the tip, the basal portion broad and narrowly sulcate, ( 5 ) much longer, rather slender, and 

 almost smooth, the peduncle of the submentum armed with a small acute tooth in front in this sex. 

 Prothorax a little longer than broad, subcylindical, constricted in front, feebly bisinuate at the base ; 

 sparsely, very finely punctate. Scutellum long and narrow, shallowly sulcate. Elytra very little wider than 

 the prothorax, long, subparallel, finely punctate-striate. Pygidium long, conical, closely punctate. First 

 ventral segment slightly depressed down the middle in the $ . Femora fringed with long hairs beneath. 



Var. Elytra black, the sixth interstice only with a ferruginous streak, the prothorax with a similarly- 

 coloured broad marginal vitta (in one specimen extending inwards, so as to leave an elongate, basally- 

 dilated stripe, and a small spot on each side of it at about the middle, black). (Fig. 9.)

Apparently not rare in the Mexican State of Guanajuato. A small, narrow, elongate, 

 parallel-sided form, with a very broad rufous stripe on each elytron, the sides of the 

 prothorax also usually more or less marked with red. The variety with the rufous 

 coloration on the elytra reduced to a narrow streak on the sixth interstice is from 

 Guatemala.
