1879.] PHYTOPHAGOUS COLEOPTKRA. 779 



base and apex ; surface rather more deeply punctured than the head. 

 Scutellum elongate, pubescent. Elytra much wider than the thorax, 

 parallel, convex, the space below the base very slightly transversely 

 depressed ; humeral callus prominent, smooth ; surface very deeply 

 punctate-striate, the interstices costate and partly, especially towards 

 the sides, transversely wrinkled, here and there covered with more 

 minute punctures, and covered with long whitish stiff hairs. Base 

 of the femora and tibiae fulvous, apex of latter and the tarsi 

 piceous. 



This species, which was sent over by Mr. Champion in numerous 

 specimens, may be readily known from others by its metallic bronze 

 colour and the deep punctured striae on the elytra. 



Genus Colaspoides, Castlenau. 



11. Colaspoides batesi, sp. nov. 



Broadly ovate, convex ; shining metallic green, base of antennae 

 and palpi fulvous ; head and thorax obsoletely punctured, elytra 

 distinctly punctate-striate. 



Length 2|-3 lines. 



Hab. Costa Rica. 



Head impunctate on the vertex, with a distinct fovea in the mid- 

 dle, clypeus bounded on either side by a deep depression, punctured 

 and obsoletely transversely wrinkled ; labrum aeneous ; antennae 

 longer than half the length of the body, the four basal joints fulvous, 

 the rest black ; apical joint of palpi piceous. Thorax transverse, 

 nearly three times as broad as long, narrowly margined, surface 

 convex, obsoletely punctured. Scutellum large, oblong, impunctate. 

 Elytra slightly wider at the base than the thorax, convex, and obso- 

 letely obliquely depressed below the humeral callus ; surface covered 

 with numerous irregular rows of distinct but not deep punctures ; 

 interspaces smooth, impunctate. Underside, legs, and tarsi metallic 

 green, the latter rather darker. 



To be distinguished from C. smaragdula, Lefev., and other allied 

 species by its uniform coloration of the legs and tarsi and the obso- 

 lete punctuation of the thorax, as well as by the colour of the 

 labrum. 



12. Colaspoides peruana, sp. nov. 



Oblong, convex. Dark violaceous blue, shining ; palpi, base 

 of antennae, and the legs fulvous ; thorax distantly, elytra closely 

 punctate-striate. 



Length 4 lines. 



Hab. Chanchomayo, Peru. 



Head deeply but distantly punctate, front impressed in the mid- 

 dle with a longitudinal groove ; labrum fulvous ; mandibulae black : 

 antennae rather more than half the length of the body, filiform ; the 

 third and fifth joints of equal length ; second joint small, ovate ; the 

 four basal joints fulvous, the rest black. Thorax more than three 

 times as broad as long, very convex, the sides and the posterior mar-
