DESCRIPTIONS OF SOME NEW SPECIES OF SOUTH 



AMERICAN CHRYSOMELINiE. 



By Martin Jacoby, F.E.S. 



In 1876 Kirsch has described, in the ' Deutsche Ent. Zeitsch.,' 

 some species of Dorypliora, and placed them in the genus Chrijso- 

 mcla, under which heading they figure also in the Catalogue of 

 Duvivier. It is most remarkable that, although the genus Dorij- 

 pliora is about the most easily to recognize amongst the whole 

 of the Phytopliaga, and Kirsch knew well apparently this genus, 

 he should have retained the name of CJirysomela for it, since this 

 genus has no true representative in South America. 



DORYPHORA SANGUINIPENNIS, D. Sp. 



Below metallic violaceous ; head and thorax black, shining, nearly 

 impuuctate ; elytra light rei\, very finely punctured in irregular rows, the 

 sutural and lateral margins narrowly black. Length, 9 lines. 



Head black, impunctate at the vertex ; the clypeus very finely and 

 sparingly punctured ; the eight lower joints of the antennfe black, the others 

 wanting ; thorax strongly transversely convex, at least three times broader 

 than long, the sides strongly rounded, narrowed at the base, the anterior 

 angles mucronate, the disc shining, with some very fine punctures at the 

 sides only, the centre impimctate, with a small fovea at the sides ; scutelhim 

 black ; elytra very convex, parallel, of reddish orange colour, very narrowly 

 margined with black, the surface very finely, not very closely, punctured, the 

 punctixres very irregularly arranged in rows, the interstices impunctate ; 

 under side and legs violaceous blue ; mesosternal process moderately long, 

 acute, slightly curved. 



Hab. Venezuela (my collection). 



This large-sized species is of similar shape as D. hatesi, and 

 seems allied to D. augur, Stal, in coloration, but differs in the 

 nearly impunctate thorax and the finely punctured elytra. 



DoRYPHORA OBLIQUEFASCIATA, n. Sp. 

 Black; head and thorax greenish, opaque, finely punctured; elytra 

 closely geminate punctate-striate, flavoiis, the suture and two transverse 

 oblique bands, one before, the other below the middle, piceous or greenish, 

 Ijength, 5 lines.
