EUPHRYTUS. 209 
6. Euphrytus fulvicornis. 
Bluish-black ; the antenne, head, and thorax fulvous; elytra dark bluish or greenish, opaque, very finely 
geminate-punctate-striate. 
Length 2-23 lines. 
Hab. Mexico, Ventanas and Milpas in Durango (Forrer). 
Closely allied to L. varipennis, but differing from it by the entirely fulvous antenne 
and by the opaque and silky appearance of the elytra, the punctuation of which is 
extremely fine, and in some specimens scarcely perceptible. The thorax is impunctate, 
and shaped as in E. varipennis; the femora are also unarmed. The specimens received 
are apparently all females. 
7. Euphrytus umbrosus. 
Elongate, subcylindrical, dark sneous, the base of the antenne pale; thorax finely and closely punctured ; 
elytra more strongly and very closely punctured, the interstices at the apex convex. 
¢g. The antenne more than half the length of the body; the posterior femora toothed. 
@. The antenne much shorter; the posterior femora unarmed. ~ 
Length 3 lines. 
Hab. Mexico, Chilpancingo, Omilteme, and Tepetlapa, all in Guerrero, Cuernavaca in 
Morelos (H. H. Smith). 
Of darker general colour than ZH. wneus; the antenne black (the second to the fourth 
joints excepted) and much shorter, the terminal joint in the male curved and widened ; 
the legs dark neous; the tooth on the posterior femora in the male smaller and shorter, 
and the intermediate tibie curved near the apex. The armed femora and dark legs 
distinguish it from E. simplex ; and the shorter antenne and their colour from the last- 
named species and from £. varicornis also. 
8. Euphrytus varicornis. 
Elongate, obscure dark bronze ; antenne testaceous, the seventh and the two terminal joints fuscous; thorax 
very closely punctured ; elytra very closely semipunctate-striate ; legs testaceous; femora unarmed. 
Length 3 lines. 
Hab. Mexico, Chilpancingo, Iguala, and Amutla, all in Guerrero (Hoge, H. H. Smith). 
E. varicornis is very closely allied to E. simplex, and is possibly only a variety of 
that species; it differs principally by the colour of the antenne, which is constant in 
the eight examples before me. The thorax is also rather longer and devoid of any 
depression. In the specimens which I suppose to be the females the antenne are only 
half the length of the body. 
9, Euphrytus pallidus. (Tab. XL. fig. 13.) 
Elongate, entirely pale flavous; thorax minutely and closely punctured; elytra more strongly and very closely 
punctured, the interstices slightly raised on the disc, distinctly costate near the apex. 
Length 23 lines.
