350 COLEOPTERA 



The head is finely and rugosely sculptured ; the carina of the fore- 

 head is well defined, most conspicuous near the eye, becoming finer and 

 angulated anteriorly till it unites with its fellow, thus giving the forehead 

 a somewhat triangular appearance ; there are a few fine reddish-yellow 

 scales on its surface. Tht protluvax is very large, nearly as large as the 

 elytra, convex, a good deal dilated laterally and narrowed behind ; its 

 surface is finely punctured, seemingly, but the sculpture is much con- 

 cealed by its clothing of bright reddish-yellow scales. The elytra are 

 comparatively short, convex, obovate, emarginate at base, and a good 

 deal narrowed at the apex ; they are finely punctate, and, like the 

 thorax, clothed with bright reddish-yellow scales. The legs are short 

 and stout. 



The large posteriorly narrowed thorax in conjunction with the 

 obovate elytra, give this very fine brightly-coloured insect quite an 

 elliptical outline.

I found three specimens in the forest at Parua, near Whangarei 

 Harbour. 



638. C. perpinguis, n.s. Body nude, short, broad, and convex ; 

 the thorax and elytra of nearly equal size, both a little narrowed towards 

 their bases, so that the general outline is somewhat elliptical ; the body 

 is shining black, with reddish legs and head, the latter darkest, the tarsi, 

 palpi, and two basal joints of the antennae are pale yellowish-red, and' 

 the rest of the antennal joints are fuscous. 



The liead has the costte strongly produced in the form of two com- 

 pressed horn-like protuberances somewhat similar to those observable 

 on the head of C. cornuticeps, but their inner edge is nearly vertical, so 

 that they are not very wide at the base, thus leaving a considerable 

 interval, which however is slightly elevated. 



Tht prot/wrax is very convex, with rounded sides, finely margined, 

 truncate base, and obtusely produced apex ; it is not very closely and 

 rather delicately punctured, and there is a rounded depression on each 

 side of the middle near the base. The elytra are obovate, somewhat 

 pointed at the apex, not much longer than and scarcely so wide as the 

 thorax ; they are very convex and abruptly declivous posteriorly, so that 

 their apical portion is nearly vertical, the base is quite truncate, the 

 scutellar region is a little depressed, and they are rather distantly 

 punctured, the punctures larger than those on the thorax, and they are 

 more polished than it. The legs are stout, and the external apex of the 

 tibiae is acutely produced. It is allied to C. iUiistris. 



Length, i line; breadth, nearly \ line. 



I found one example near Whangarei Harbour. 



639. C. anthracintlS, n.s. The fades of this species so closely 

 resembles that of C perpingins, that the two seem at first sight almost 

 identical ; the thorax, however, is smaller and more polished, the cari- 

 nated edges of the forehead, though elevated, simply define its form, 

 being prolonged anteriorly ; there is an evident incision at the base of 

 the elytra ; and the external apex of the front tibiae is not so strongly
