264 Mr. F. P. Pascoe's Descriptions of New Genera 



In the poststernal process and triangular scutellum this species 

 departs from the rest of the genus ; the colour is also peculiar. 



DORCASTA. 



Head narrow, the face inferior, eyes deeply emarginate, the upper 

 portion very narrow, antennae approximate, as long as the body, 

 the joints gradually diminishing from the first (second excepted), 

 thickened throughout and ciliated beneath ; thorax narrow, longer 

 than wide ; elytra scarcely wider than the thorax, slightly dilated 

 at the side, apiculate externally ; legs very short, meso-tarsus 

 toothed. 



Very nearly allied to Spalacopsis, Newman, but differs in the 

 undivided although deeply emarginate eye. With Systene,* Apro- 

 sopiis, Tetraglenes and Eucomatocera these insects form a small 

 natural group, distinguished by their thickened antennae, very 

 generally divided eyes, inferior face, and narrow linear form. 

 Ectalo&ia is, perhaps, an aberrant genus of the same group. 



Dorcasta oryx. 

 D. angusta, sub-parallela, hirsuta, fusca, albo-lineata ; elytris 



thorace vix latioribus. Para. 

 Narrow, brown, pubescent ; head, thorax and elytra nearly 

 parallel^ with rows of short oblique hairs ; from behind the eye 

 and extending along the sides of the prothorax and elytron two 

 whitish lines, which on the latter are accompanied by two ob- 

 scurer intermediate ones ; legs and antennae dark brown. 

 Length 3^ lines. 



Dorcasta crassicornis. (PI. XXVI. fig. 5.) 



D. validiuscula, hirsuta, albo-lineata j elytris thorace latioribus. 

 Brasilia ? 



Closely resembling the former but stouter, the elytra wider 

 than the thorax, tlie antennae very much thicker and more strongly 

 ciliated ; a longitudinal groove on the vertex, and a narrow line 

 on the middle of the prothorax, which extends to the scutellum. 



Length 4 lines. 



In Mr. Saunders's collection, without a locality. 



OCALEMIA. 



Head prolonged in front, eyes very large, round, antennae of 



* Substituted for Entheia, Guer., which had been previously used for a genus 

 of ScydiniCiiida:.
