168 * PHYTOPHAGA. 



8. Fidia lateralis. 



Oblong, black below ; above, and the antennae and legs, fulvous, shining ; thorax rugose-punctate ; elytra 

 punctate-striate, with a lateral longitudinal black band. 



Length If line. 



Head finely but very closely rugose-punctate, obscure fulvous ; clypeus light fulvous, square-shaped, rugose- 

 punctate ; antenn£e nearly as long as half the body, fulvous, last five joints much thickened, piceous ; 

 thorax cylindrical, dark fulvous, very closely rugose-punctate, sparingly pubescent; scutellum broadly 

 ovate, piceous ; elytra transversely depressed below the base, very closely punctate-striate, the puncturing 

 distinct to the apex, fulvous, shining, the sides occupied by a longitudinal black band from the shoulder 

 to nearly the apex ; underside black, legs and tarsi fulvous. 



Hab. Mexico, Orizaba {Salle). 



The only species to which the present one, of which a single specimen is contained 

 in M. Salle's collection, can be compared, is F. pedestris, from which it differs sufficiently 

 in the black underside, the closely punctured thorax, and the black elytral stripe. 



9. Fidia unistriata. 



Oblong, black, shining ; antenna piceous, their base fulvous ; thorax very distantly punctured, finely pubescent ; 



elytra deeply depressed below the base, finely punctate-striate, the suture and a stripe from the shoulder 



to the apex covered with fine white hairs. 

 Length 2-2| lines. 



Hab. Guatemala, San Geronimo, La Tinta, Chacoj (Champion). 



At first sight this species seems identical with F. albovittata, which it resembles 

 closely ; but as all the specimens from Guatemala show the same distinctive characters, 

 I must consider them to represent a distinct form, which may be separated from 

 F. albovittata as follows :— The insect shows a much more shining black upper surface ; 

 the antennse, instead of being entirely fulvous, have the base only of that colour ; the 

 thorax is more remotely punctured and entirely devoid of the central white line ; the 

 elytra, instead of having four pubescent stripes, have only a lateral stripe besides the 

 sutural one. These characters are constant in all the specimens before me. 



10. Fidia atra. 



Subcylindrical, convex ; black, closely covered with greyish-white pubescence. 



Length 2 lines. 



Head closely punctured, pubescent ; antenna? half the length of the body, black, the third and fourth joints 

 of equal length, the last five joints distinctly thickened; thorax cylindrical, widened at the middle, 

 punctured and pubescent like the head ; scutellum subtriangular, its apex obtusely rounded, thickly 

 covered with white hairs ; elytra with a circular depression below the base, obsoletely and closely punctate- 

 striate, the interstices also minutely punctured, closely covered with rather long whitish hairs ; underside, 

 legs, and tarsi black. 



Hab. Mexico, Oaxaca (Edge). 



Of this very distinct species, which is easily known by its entirely black colour, only 

 a single specimen was obtained by Herr Hoge.
