Rostrum deeply excavate, the centre depressed ; the 

 external dorsal borders thick, strongly raised, sinuous in out- 

 line, incurved towards base, rather coarsely punctate. Head 

 strongly convex, sublaevigate, minutely transversely strigose 

 posteriorly, with scattered obsolete punctures in front, with 

 a semi-circular impression running from behind crests across 

 the front of the head, ill -defined above, deeper laterally ; 

 with a small bidentate, supra-ocular crest on either side, 

 the processes small, dentiform, the posterior the larger; 

 forehead feebly convex between the crests; head separated 

 from rostrum by a deep transverse sulcus, somewhat V-shaped 

 in centre. Prothorax (7x7 mm.) subquadrate, widest in 

 front of middle, the sides sloping very gradually towards 

 base, much more abruptly towards apex ; anterior margin 

 truncate, with a small, obtusely-angulate projection behind 

 eye; disc feebly convex, somewhat flattened above; with a 

 -deep circumferential sulcus, interrupted in the middle line, 

 immediately behind apex, and with a wider concave depressed 

 area at base; median line impressed anteriorly, thence hardly 

 traceable; set with flattened, irregularly polygonal, contiguous 

 granules, the facets fitting into each other; with four small 

 dentiform tubercles on either side, an anterior pair on apical 

 declivity, and a posterior pair near latero-basal angle ; sides 

 with granules more rounded, not extending more than about 

 halfway towards coxae. Elytra (14 x 9 mm.) elongate, widest 

 near base, gradually rounded towards apex, the latter some- 

 what produced, with a mucroniform projection, separated by 

 a narrow emargination, on each side; base truncate, with a 

 small dentiform tubercle on each side at humeral angle; disc 

 flattened above, strongly declivous posteriorly; puncto-striate, 

 striae narrow, punctures small, connected transversely by 

 irregular sulci, frequently running across whole width of 

 elytron; interstices not raised, granules depressed, flattened, 

 confluent laterally; the whole sculpture confused, consisting 

 of a series of wavy transverse elevations and depressions. 

 Beneath flattened over basal ventral segments, the first seg- 

 ment somewhat hollowed out between the posterior coxae. 

 Metasternum and two basal ventral segments with scattered 

 granules, apical segments not granulate, somewhat rugosely 

 punctate. Anterior fihkie without siTbapical emargination; 

 all with moderately conspicuous granules on the under- 

 surface; tarsi short, flattened, with peculiar claw-joint char- 

 acteristic of the genus. 



9 . More ovate than the male. Head and rostrum 

 similar. Prothorax (5*5 x 6 mm.) smaller, widest about 

 middle, tubercles at sides rather stronger, mesial line 

 impressed throughout. Elytra (16x9 mm.) longer, more
