cui-\ing sharply out in front in a strongly marked course ; pre- 

 ocular sulcus short, lightly marked ; pre-ocular process small ; 

 eyes not deeply set in orbits, convex, rather prominent ; two 

 supra-orbital punctures on each side. Antennte setaceous. Pro- 

 thorax transverse (5-3 x 9 mm.) ; sides hardly narrowed to 

 anterior angles, sub-parallel on anterior third ; posterior angles 

 widely rounded, not marked ; anterior angles wide, obtuse, hardly 

 advanced ; Irnse decidedly lobate, the lobe rounded behind, a 

 strong sinuosity on each side of the basal lobe ; border strongly 

 reflexed, a little wider at anterior and posterior angles, narrower 

 on basal lobe ; marginal channel wide ; median line strongly 

 impressed ; a well marked transverse line defining basal part ; 

 four marginal punctures on each side, the anterior and posterior 

 as usual in the genus, the two intermediate ones placed about 

 midway between them a considerable distance apart.* Elytra 

 oval (13-3 X 9-3 mm.), widest about middle, convex, rather 

 depressed on disc, strongly declivous to apex and sides, abruptly 

 declivous to peduncle ; sides strongly rounded ; base sub-emargi- 

 nate between shoulders ; humeral angles prominent ; apex obtuse ; 

 border reflexed, more lightly so towards apex, thickened and up- 

 turned at each humeral angle to form a strong pr-ominent obtuse 

 projection ; margin wide, most so and flattened on apical curve ; 

 a strong discoidal puncture on apical third of each elytron, placed 

 a little nearer the suture than the margin just behind beginning 

 of apical declivity ; four or five fine punctures in a curved 

 row, with a larger puncture below them, on base of each elytron ; 

 a row of punctures along margin ; suture forming a strong depres- 

 sion. Prosternum strongly impressed between coxae, truncate 

 on base ; one or two setigerous punctures on each side just before 

 base. Legs light : anterior tibife tridentate externally, the upper 

 tooth small ; external ridge with two light projections above 

 larger teeth ; inferior ridge strongly serrate, not extending to 

 apex ; apical plate projecting strongly below tarsus at apex. 

 Length 26, breadth 9-3 mm. 



* It is probable the normal number of marginal punctures may prove to 

 be three placed as in C. ockn-ahnii, Casteln., &c.
