and raised at the base, the apex rounded and swollen, an oblique 

 narrow yellow basal line, and at about the middle another, but dilated 

 outwardly, the two forming together an interrupted X mark ; femora 

 moderately clavate, the posterior with a spine at its extremity, tarsi 

 slightly curved, densely clothed with golden-yellow hairs internally on 

 its lower half, tarsi rather short 5 antennse with a silvery pubescence, 

 the terminal joints very strongly dilated. Length 11 lines. 



Near ;S^. coarctata, Fab., but with the prothorax shorter and more 

 rounded at the sides, its surface longitudinally marked with fine, 

 wavy, more or less connected lines ; the elytra much longer and 

 narrower, and more decidedly contracted in the middle, &c. &c.

Sthelenus morosiis. 



S. fuscus, opacus ; elytris abbreviatis, singulis maculis elongatis tiibus 

 flavis', antennis articulo secimdo longiore, incrassato, piloso. 



Hah. Caraccas. 



Dark brown, opake, with a few stiiF black hairs ; head wider than 

 the prothorax, and about one-half its length, covered with large, coarse, 

 often confluent pimctures, somewhat transversely arranged, especially 

 on the vertex, front slightly concave ; lip small, ferruginous ; palpi of 

 nearly equal length, pale ferruginous ; prothorax nearly cylindrical, a 

 little constricted towards the base, the disk with numerous fine trans- 

 verse irregular plaits 5 scutellimi rather elongate, roimded behind, 

 somewhat concave ; elytra coarsely punctured, much wider than the 

 prothorax, nearly flat above, curved slightly inwards at the side, not 

 extending beyond the base of the fourth abdomiaal segment, each 

 having three oblong longitudinal patches (the last two nearly con- 

 tinuous) of bright-yellow, curved, appressed hairs ; legs rather short, 

 tibiae and tarsi slender ; body beneath pitchy bi'own ; antennae scarcely 

 longer than the body, the third joint thicker than the basal, and largest 

 of all, hairy, the seventh to the eleventh inclusive short and a little 

 dilated. Length 8 lines. 



The above applies exclusively to the male ; the female is smaller, 

 more ferruginous, with longer antennae, the terminal joints not 

 dilated, but the third as thick in proportion as in the male. Instead 

 of referring this species to the genus Sthelenus of M. Buquet, it will 

 perhaps be thought that it would have been more advisable to have 

 considered it as the type of a new one. I regard Sthelenus, however, 

 as very closely connected with Ozodes, Lew. ; and as in that genus we 

 find the prothorax more or less nodose, and the third (and sometimes 

 the fourth and fifth) joints of the antennae considerably incrassated.
