 have the terminal hook feeble and in addition are suj^plied with 

 a small subapical tooth, both in the posterior being very 

 indistinct. 



M E L A N T E R I O S O M A, n.g. 



Head moderately convex, not concealed; ocular fovea indistinct. 

 Eyes rather narrowly ovate, coarsely faceted. Rostrum moder- 

 ately long, not very thin, not passing mesosternum, feebly curved, 

 slightly dilated in front of antennee. Antennc^. thin; scape the 

 length of funicle, inserted nearer apex than base of rostrum; two 

 basal joints of funicle moderately elongate; club small, ovate, free. 

 Protliorax slightly transverse, subconvex, sides rounded, apex 

 feebly produced and much narrower than base, base feebly bisin- 

 uate; ocular lobes obtuse. Scutellavi r,uboblong. Elytra cordate, 

 considerably wider than and not thrice the length of prothorax, 

 shoulders and apex rounded. Pectoral canal wide and rather 

 deep in front of anterior coxfe, these excavated and distinctly 

 separated. Mesosternal plate depressed, transverse, slightly 

 concave, apices raised and slightly produced, base truncate. 

 Metasternum shorter than basal segment of abdomen; episterna 

 moderately large. Abdomen large, sutures distinct; 1st segment 

 not twice the length of 2nd, intercoxal process rounded and 

 rather wide; intermediates not depressed, their combined length 

 more than that of 2nd or 5th. Leys rather long; femora moder- 

 ately stout, feebly grooved, and all rather acutely dentate ; 

 posterior terminated near apex of abdomen ; tibiee bisinuate 

 beneath; tarsi narrow except the 3rd joint which is rather 

 wide and deeply bilobed; claw-joint long and thin, strongly 

 exserted, claws feeble. Ovate, moderately convex, punctate, 

 squamose, winged. 



Allied to Melanterius but separated on account of the rostrum 

 not passing the mesosternum; from Psydestis it differs in the 

 coarsely faceted eyes and larger 2nd abdominal segment.
