552 PHYTOPHAGA. 



specimens the bands are more or less connected and occupy nearly the entire disc, in 

 others they are only indicated by small spots. 



We figure a typical example from the Volcan de Atitlan, and the var. b from San 



Isidro. 



114. Diabrotica hirsuta. 



Piceous, the head black; thorax obscure piceous, obsoletely bifoveolate; elytra flavous, closely pubescent, the- 

 suture, a lateral spot at the middle, and a transverse band near the apex, black. 



Length \\ line. 



Head not longer than broad, black, the frontal tubercles distinct, the vertex with a few minute punctures ; 

 antennae two thirds the length of the body, the third joint twice the length of the second, the four lower 

 and the three apical joints obscure testaceous, the intermediate ones nearly black; thorax subquadrate, 

 constricted near the base, the surface impunctate, with a small fovea on each side, of a pale piceous 

 colour ; scutellum black ; elytra closely punctured, the punctuation arranged in nearly regular rows 

 (more distinct below the shoulders) and consisting of small and larger impressions, the disc closely 

 covered with whitish pubescence, an elongate spot at the sides extending from below the shoulders to the 

 middle, a narrow transverse band extending across the suture near the apex, and the suture narrowly, 

 black; the base of the femora yellowish-white, the rest of the underside and the legs piceous. 



Hab. Mexico, Colima city {Edge). 

 A single specimen. 



115. Diabrotica depressa. 



Broadly ovate, depressed, testaceous, the antennae stained with piceous above ; thorax transverse, obsoletely 

 bifoveolate ; elytra irregularly punctured, testaceous, with a transverse band at and another below the 

 middle (connected at the suture), and a small spot at the base, black. 



Var. Elytra almost entirely black, the base and the sides with testaceous spots. 



Length 2^-3^ lines. 



Head with a more or less distinct fovea on the vertex, the latter impunctate, sometimes stained with piceous 

 at the base ; the frontal tubercles elongate, nearly contiguous, and joined to the clypeus ; antennas but 

 little shorter than the body, the apex of each joint testaceous, the first joint entirely of that colour, the 

 others piceous above, the third joint twice the length of the second but distinctly shorter than the fourth ; 

 thorax strongly transverse, more than twice as broad as long, the margins nearly straight, the surface 

 flattened, impunctate, and with a small obsolete fovea on each side ; scutellum broad, testaceous ; elytra 

 flattened, finely punctured anteriorly, the posterior portion nearly impunctate, the black pattern of 

 variable shape (somewhat resembling the letter oc), the apical and basal portions testaceous, the latter 

 with one or two small black spots ; the underside and femora testaceous, the tibise and tarsi more or less 

 piceous ; the first joint of the posterior tarsi longer than the following two joints together. 



Hab. Mexico, Cordova (SalU). 



This is a species of a peculiarly broad and flattened appearance, possessing, however, 

 all the structural characters of Diabrotica. The thorax is broader than in most of the 

 allied forms, being nearly as wide at the base as the elytra. The elytral markings are 

 somewhat in the form of the letter #, and of variable thickness, the anterior hook 

 being sometimes connected with another black stripe extending upwards to the 

 shoulders, the small black spot at the base in some specimens nearly obsolete, in others 

 well-marked ; in the variety the black colour predominates to such an extent as only
