una basali, alteins duabus paulo post medium ; pedibus 

 brevibus, robustis. 

 Long. 8 lin. c?. 



Of less cylindrical form than the preceding, the elytra 

 tapering towards the apex, and each prolonged there 

 into an elongate black spine ; the thorax is oblong, 

 rounded in the middle, and very closely covered with 

 large punctures, or fovese, giving a reticulate appear- 

 ance; lying across the middle are four black spots, 

 beside one on each side on the anterior margin. Ely- 

 tra coarsely punctured, and with minute punctures on 

 the interstices between the larger ones ; setose, the apical 

 third nearly smooth and shining ; the basal eburneous 

 spot is large and oblong, bordered with black behind ; 

 the two posterior spots consist of a smaller inner one, 

 and a much larger outer one, the smaller a little in ad- 

 vance of the other, and separated distinctly from it; they 

 are edged with black before and behind. The legs are 

 short and stout, the hind femora not reaching, by a long 

 way, the apex of the elytra; the knees are black. 



This very distinct species occurred only at Para- 



Genus Opades. 

 Lacordaire, Gen. viii. 288.- 



1. Opades vittipennis, n. sp. 



Elongatus, cinnamomeo-fuscus, pube subtili sericea 

 vestitus ; elytris oblongis, vix convexis, sutura et vittis 

 utrinque tribus obscurioribus notatis.

Differs from 0. costipennin , according to the descrip- 

 tions of Buquet and Lacordaire, in its broader and less 

 cylindrical form, and in the colour of its fine dense pu- 

 bescence, which in 0. costipennis is " greenish-gray," 

 and in our species is of a dingy brown, or cinnamon- 

 brown hue. Both species have two elevated and almost 

 spiniform black tubercles on the disc of the thorax. The 

 dark vitt^e of the elytra lie along the interstices of the 

 costae, and are distinctly seen only in certain lights.
