638 Longicornia Malayana. 



Demonax ? palliatus. (PI. XXII. fig. 8.) 



D. nigro-fuscus^ opacus, elytris (basi excepta) flavo- 

 cinnamomeis. 



Hah. — Gilolo. 



Blackish-brown, opaque, a large round spot on each 

 side of the prothorax posteriorly, and the elytra, except 

 a small portion of the base, yellowish-cinnamon, the latter 

 very pure and uniform, the spots dull and indistinct ; body 

 beneath dark brown, the breast, mesosternura, epipleurs9 

 of the metasternum, and a curved band on the abdomen, 

 including the posterior angles of the first and the whole 

 of the second abdominal segment, lemon-yellow ; legs dull 

 brown, the tarsi pale ferruginous ; antenna3 brown, gra- 

 dually paler outwards, more than half the length of the 

 body ((J ?); head with a carina on each side from the 

 lower part of the eye to the mouth, no median carina; 

 prothorax globose, a little narrower at the apex than at 

 the base, the elytra rather narrower than the prothorax, 

 their apices slightly emarginate, scarcely spined at the 

 outer angle. 



Length 7 lines. 



Denionax ? oitelanurus. 



D. flavo-ochraceus ; capite, prothoracis macula triangu- 



lari basali, elytrisque basi, nigro-fuscis. 

 Hab. — Batchian. 



Yellowish-ochraceous ; the head, a triangular spot at 

 the base of the prothorax, and slightly along the base of 

 the elytra, blackish-brown; body beneath pale ashy, the 

 last three abdominal segments black ; legs blackish-brown, 

 tarsi ochraceous ; antennae dark brown, paler outwards, 

 three-fourths the length of the body; frontal carinas as 

 in the last ; the prothorax less globose, the elytra more 

 tapering posteriorly. 



Length 5^ lines. 



This and the above are two very distinct species, quite 

 difierent in coloration from all their congeners, and 

 having the prothorax broad and strongly rounded at the 

 sides. I originally intended to place them in a distinct 

 genus, but as each is represented only by a single indivi- 

 dual, the former judging from the abdomen a female, the 

 latter a male, the data for such a step are scarcely suffi- 

 cient.
