392 OETHOPTEEA. 



<$ . Minor. Tibiis anticis nonnunquam subtus immaculatis. 



Var. Elytra nigro punctulato. — [Costa Rica.] 



2 . Long. 30-36 ; pronot. 9 ; proc. vertic. 2 ; elytr. 51-57 ; femor. post. 31 ; ovipos. 31-33 millim. 



c?. Long. 27; pronot. 8; elytr. 40; vertic. 1-3; femor. post. 23 millim. 



Hab. Mexico, Teapa in Tabasco (H. H. Smith) ; Costa Kica (Bogers), Rio General, 

 Pacific coast [var. minor]. 



This species is very like C. pichinchce, Boliv., in colour, but it is much larger, and has 

 the process of the vertex twice as long as in that insect, and not at all conic, and the 

 elytra reaching much further beyond the hind femora. It differs from C. guttatus, 

 Serv., in its longer ovipositor and shorter elytra ; and from C. mesticanus in having 

 the four anterior femora maculated with black. C. aztecus should be placed near 

 C. mawillosus (Fabr.), from which it may be distinguished by the shorter and broader 

 process of the vertex, not attenuated at the tip, and by the spotted femora.

This species is fulvous or testaceous in colour, but the markings are variable. The 

 elytra are frequently dotted with black, and sometimes have the anterior margin brown. 

 The pronotum generally has a brown marginal stripe, which is continued on to the 

 principal vein of the elytra.
