84 COLEOPTERA 



respects, but as the extra-European allied species are numerous and but 

 little known, it would be premature to make a new generic name for it. 



153. C. flavicorne, n.s. Oviform, rather short, convex, shining, 

 black, with the thoracic margins reddish ; legs red, palpi and antennae 

 clear yellow, with the club of the latter dull. 



Antenna with an elongate basal joint, not greatly thickened apically 

 and as long as joints two to six taken together; second joint ovate-elongate, 

 nearly as long as the three which follow ; fourth and fifth short, trans- 

 verse ; sixth broader than fifth, nearly as long as the fourth and fifth 

 conjointly, club large, not very laxly articulated, not so long as the rest 

 of the antennae. Maxillary palpi elongate, not much shorter than the 

 antennae, the terminal joint longer than the third. Head ovate, slightly 

 convex; epistome truncated in front; distinctly, but neither very closely 

 nor coarsely punctured, with rather prominent eyes. Prothorax trans- 

 verse, apex emarginate, base rounded, with a slight sinuation at each 

 side of the middle, rounded laterally, and narrowed towards the front ; 

 its surface is very finely and rather distantly punctured, its punctation 

 much finer than that of the head. Scutellum moderate. Elytra convex, 

 more than twice the length of the thorax, finely margined, not at all 

 explanated ; each elytron bears ten rows of punctures, those on the disc 

 least distinct, the outer rows very coarse and not attaining the base ; 

 the interstices are punctured in very much the same way as the head, 

 much more coarsely than the throat. Legs moderate, the posterior 'tibia 

 on the inside with rather large, elongate, punctiform impressions ; the 

 second joint of the tarsus is not so long as the next three conjointly, 

 but twice as long as the third, the basal joint short, not much exposed. 

 The tarsi bear yellow hairs. 



Length, 2j; breadth, nearly ij lines (set out). 



I found two specimens at Tairua, one of which I sent to Dr. Sharp, 

 who, however, has not described it. 



I 54- C. gibbOSUMl, n.s. This species is verysimilar to C. flavicorne, 

 being of the same colour and nearly the same form, but it may be at 

 once known by its very convex elytra, which, in C. flavicorne are not 

 more elevated at the suture than elsewhere, whereas, in this species, the 

 sutural portion is distinctly elevated, so as to appear humped when 

 viewed from the front ; the third antennal joint is not appreciably 

 longer than the fourth ; the punctation of the thorax is more distinct, 

 being nearly the same as that of the head ; and the apex of the elytra 

 is more obtuse ; these latter are sculptured as in the previously men- 

 tioned species. 



Length, 2 lines ; breadth, i \. 



I have but a single individual, which I found near Whangarei Heads. 



155. C. frontale, n.s. Convex, short oval, moderately shining, 

 pitchy black, with the margins reddish, legs dark red ; antennae and 

 palpi testaceous, rather pellucid, except the club of the former, which, 

 owing to its excessively fine pubescence, is rather dull. 



Labrum\zxgz< exposed, emarginated in front, finely punctated, and 

 reddish. Head subovate, subdepressed, moderately finely punctured,
