594 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA. [Nov. 16, 



and the apex of the elytra metallic rufo-aureous, margined with 

 green. 



Length 4 lines. 



Upper part of the head rufo-aureous, remotely and deeply punc- 

 tate, lower part metallic bluish green, more tinely punctate, labrum 

 and the four basal joints of the autennse fulvous, rest of the joints 

 black. Thorax long for this genus, about twice as long as broad, the 

 anterior margin straight, the sides evenly rounded, all angles acute 

 but not produced ; surface remotely but deeply punctate, intermixed 

 ■with minute punctures, coloured like the upper part of the head, 

 margined with metalHc green ; scutellum pentagonal, smooth, of the 

 latter colour. Elytra not wider at the base than the thorax, deeply 

 punctate near the sides, finer and much more distantly towards the 

 apex, the punctures at the latter placed regularly in double rows, 

 otherwise confusedly arranged ; extreme apex brilliant metallic green, 

 bordered with rufo-aureous above, but not extending to one third of 

 the length of the elytra. 



This species is also found in the Amazonian region. 



Mus. Jacoby. 



Genus Eumolpus, Weber. 



25. Eumolpus prasinus, Erichs. 



Amongst the normal-coloured specimens an entirely black variety 

 has been collected, which, however, does not differ in other respects. 



26. Eumolpus surinamensis, Fabr. 



Genus Colaspoides, Casteln. 



27. Colaspoides cupreipennis, sp. nov. 



Subrotundate, convex. Rufous ; last seven joints of the antennae 

 black ; elytra greenish aureous, shining, finely punctate. 



Length 3 lines. 



Head impunctate ; clypeus separated from the front by a more or 

 less triangular transverse groove ; jaws black ; antennae two thirds 

 the length of the body, third joint one third longer than the fourth, 

 four basal joints fulvous, the others black, rather compressed from 

 the seventh joint. Thorax narrow, about three times as broad as 

 long, the anterior margin not produced, sides rounded, fulvous, sur- 

 face smooth, impunctate. Scutellum subtriangular, impunctate, 

 aeneous or |iur|)lish. Elytra convex, rounded towards the apex, 

 obsoletely obliquely depressed round the humeral callus; surface 

 finely semipunctate-striate, the punctuation not very closely placed, 

 dark greenish or purplish aeneous. Underside and the legs entirely 

 rufous. 



Closely allied to C. bicolor, Oliv., but distinguished by the colour of 

 the elytra, which is blue in this species ; it may, however, be but a 

 local variety of that insect. 



Mus. Godman and Salvia.
