490 Longicornia Malayana, 



Dark brown, pubescence dull and opaque ; head with 

 six fulvous-rose spots, four in front and two on the 

 cheeks ; prothorax grayish-brown, mottled with dark 

 brown, coarsely punctured, a slightly elevated line in the 

 middle anteriorly in the male, less marked in the female ; 

 elytra less strongly punctured than the prothorax, each 

 with six slightly raised lines, two of which are a little 

 more prominent than the others, three or four narrow 

 waved ashy bands, the basal one indefinite and more or 

 less broken up and divided ; body beneath and legs ashy, 

 speckled with pale brown; antennee reddish-brown. 



Length 9 lines. 



The male of this species has the prothorax much 

 less dilated than any of the preceding, and the female 

 shows little more than a rough line on each side. 

 M. Blanchard^s figure of Tiuesi^ternus adsjjersus agrees 

 tolerably well with P. Jiexuosa, but his description does 

 not. 



The following is referred to Polyxo, from its evident 

 affinity to the present species, but all traces of a margi- 

 nate side to the prothorax have disappeared.
