2. Hucyciotropis barynotus, sp. n. (Tab. X. fig. 18.) 
9. Black, covered with a greyish clay-coloured pubescence above, dotted with black-brown in the sutural and 
_alternate interspaces of the elytron; shaft of antenna and tarsi rufous, the latter and antennal segments 
7 and 8 pubescent white; pubescence of underside sparse, in speckles. 
Rostrum half as broad again as long, flat, feebly depressed transversely at base, with a naked mesial line. 
Frons densely rugulose. Eye somewhat oblique, direction of the long axis crossing rostrum. Antenna 
reaching to base of prothorax ; segment 3 twice as long as 2, longer than 4, 8 hardly half as long again 
as apically broad, 10 twice as broad as long; 11 rufescent. 
Prothorax strongly convex, a little wider at base than at apex, side rounded from carina to apex. Elytra 
truncate at base, not emarginate, shoulder-angles not projecting, sides parallel from base to beyond 
middle, then rounded; dorsum convex, suture not much depressed, alternate interspaces all somewhat 
convex, especially the third ; a rounded prominent basal gibbosity. 
Anterior coxe not close together. Mesosternal process feebly tuberculate at apex. Intercoxal projection of

& more than twice as long as apically broad, very much narrower than 9; 11 a little broader than 
long, rounded. 
Prothorax longer than broad, widest at carina, strongly convex, with indication of a central gibbosity. Elytra 
peculiar in shape, emarginate at base, gradually and strongly elevate from base to middle, then gradually 
rounded-declivous, appearing subglobular, apart from base; regularly punctate-striate, the interspaces 
slightly convex, alternate ones a little more raised and more obviously chequered brown and luteous.
