NEW PHYTOPHAGOUS COLEOPTERA 197 



Allied to R. alternata and R. nigripennis Baly. Separated from 

 either by the shining and impunctate head and thorax , the 

 finely punctured elytra and the colour of the anterior femora. 



The genus Rhyparida, established Ijy M.'' Baly, seems to 

 rival in the numbers of its species the genus Colaspis of the 

 new world, which it resembles somewhat in general appearance. 

 The emargination of the four posterior tibiae and the bifid claws 

 distinguish principally the genus Rivjparida which however con- 

 tains some species which on account of the convexity of the 

 anterior thoracic episternum ought to be separated and placed 

 in another genus. The determination of the species is often very 

 difficult more than 70 having been described by M.'^ Baly. I 

 am compelled to augment again considerably this number, as 

 those contained in the present collection seem all of them un- 

 described as an examination of M.'" Baly's types in the British 

 Museum, has proved to me. 



12. Rlxyparicla, strig-icollis, n. sp. 



Light fulvous. Head impunctate. Thorax closely strigose-punc- 

 tate. Elytra strongly punctate-striate, more finely towards the apex. 



Length 2 lines. 



Head opaque , impunctate with the usual longitudinal groove ; 

 episteme distinctly separated, as broad as long, finely and ra- 

 ther closaly punctured , its anterior margin distinctly concave at 

 the middle ; eyes almost entire. Antennae rather more than half 

 the length of the Ijod}? , entirely fulvous. Thorax twice as broad 

 as long , the sides regularly rounded , all the angles devoided of 

 any tubercles, surface very closely and finely punctured , the 

 punctures at the sides having the appearance of striae. Scu- 

 tellum distinctly broader than long. Elytra very obsoletely de- 

 pressed below the base , strongly punctate-striate , the punctua- 

 tion close but finer towards the apex, the space in front of 

 the lateral margin somewhat compressed and advanced in shape 

 of a blunt ridge. Anterior tiljiae in the male, dilated at its 

 latter half.
