straight, densely ciliate. Cerci ciliate, more or less depressed, 

 sublanceolate, distinctly longer than the lamina. 



The species comprised in this genus resemble the females of 

 Ejnlcmij^ra very much in shape and colour, and also in the more 

 or less united valvules of the females, but diifer very much in the 

 two sexes being without a trace of elytra or wings. Nearest to 

 them in general resemblance come some of the conspicuously- 

 banded species of Plntyzosteria, like P. halteata, Ardrossanensis, 

 &c. I have therefore placed them here provisionally, though 

 perhaps a better position could be found. The systematic posi- 

 tion of this new genus is indicated in the synopsis, post p. 

 The generic name is an allusion to the resemblance mentioned 

 above. The three species possess a type of colouring peculiar to 

 them, and characterised by the double pair of light and dark 

 bands of the abdominal segments.

 antenna? slender, ciliate, blackish, much longer than half the 

 body. Pronotum slightly truncate in front, laterally with 

 numerous small, deeply -impressed dark dots ; disk with numerous 

 brownish-red, irregular spots and streaks arranged in a circular

 underside reddish-brown, coxre bordered pale-yellow, tibae and 

 tarsi mostly dark-brown. Abdomen yellowish above, with 

 numerous red impressed dots, angles obtuse, not produced ; hind- 

 margin very broadly dusky olive, sometimes absent in segments 

 six and seven ; ventral segments two to five with a broad greenish- 

 olive band bordered very narrowly Avith yellow anteriorly, 

 segment seven concolorous, segments seven to eight with the
