EPITEIX. 351 



A single specimen in the Salle collection, agreeing with the short description given 

 by Crotch, is probably referable to this species. E.fuscula is certainly the largest 

 species, amongst those which have black elytra, with which I am acquainted. The 

 thorax is very strongly and closely punctured, and might almost be called rugose- 

 punctate ; the elytra are also very deeply and regularly punctate-striate, closely covered 

 with long yellowish pubescence, and their interstices are slightly longitudinally convex ; 

 the antennae and tibiae are fulvous. 



The species is of a much more broadly ovate shape than any other described here or 

 by Von Harold ; and as Crotch also remarks that E. fuscula is broader than E. cucumeris, 

 it is very probable that the Mexican specimen is identical with Crotch's species. 



13. Epitrix convexa. 



Ovate, subcylindrical, very convex, black ; antennae and tibise fulvous ; thorax closely and strongly punctured ; 



elytra with a strong basal elevation, distinctly punctate-striate, the striae visible to the apex ; epistoma 



rugose, subcostate. 

 Length 1 line. 



Hab. Guatemala, San Juan in Vera Paz (Champion). 



Of this species only a single specimen was obtained by Mr. Champion. I am not 

 able to unite it with any of the other described species. The principal points of 

 distinction are :— The head, although impunctate, generally has a few deep punctures 

 close to the inner margin of the eyes, and the epistoma is deeply longitudinally rugose 

 or channelled ; the antennae are entirely fulvous, as well as the tibiae. The shape of 

 the insect is more robust, cylindrical, and convex than any of the preceding species ; 

 the elytra are without pubescence (perhaps owing to abrasion), and the base is much 

 more strongly raised than is generally the case. E. lucidula, Har., has the straight 

 thoracic groove in common with the present species, but in the latter, besides the 

 general different shape, the elytral punctuation is distinct to the apex ; in E. lucidula 

 it is almost obliterated. E. puberula, Bohem., of which I have specimens named by 

 Boheman for comparison, seems to be more closely allied to E. convexa than to any 

 other species with which I am acquainted ; but the former is smaller and of different 

 shape, and the elytral basal elevation much less distinct ; the rugose epistoma would 

 furnish another good character of separation. 



14. Epitrix intermedia. (Tab. XXI. fig. 3.) 



Black ; basal joints of the antennas, base of the tibiae, and tarsi fulvous ; thorax strongly and closely punctured ; 



elytra without basal elevation, deeply punctate-striate to the apex, the interstices convex and pubescent. 

 Length 1^ line. 



Hab. Mexico, Orizaba, Guanajuato (coll. Salle); Guatemala, Volcan de Agua 



(Champion). 



In its larger size this species resembles E. murina, Harold, from which I am obliged
