322 COLEOPTERA 



582. 0- amplum, n.s. Broad, convex, moderately shining ; head 

 pitchy, body testaceous-brown, antennae and legs testaceous. Antennce 

 with the third joint not much more than half the length of the fourth. 

 Head broad, with two more or less distinct interocular depressions, 

 indistinctly punctate, and pubescent. Thorax short, about as wide 

 behind as the base of the elytra, obtusely lobed in front, the base bisin- 

 uated, sides nearly straight ; its surface is finely and remotely punctured. 

 Elytra slightly depressed along the suture near the scutellum, not at all 

 depressed transversely, closely and moderately punctured. 



The pubescence consists of fine yellowish hairs, which, however, seem 

 to have been rubbed off the more elevated parts of the body, leaving the 

 elytral disc almost bare. 



Length, 2^ lines ; breadth, \\. 



I am indebted to Mr. J. Buchanan, F.L.S., of Wellington, for my 

 specimen, which is, unfortunately, mutilated. 



583. C. viridipenne, n.s. Broadly oval, convex, shining; the 

 thorax, shoulders of elytra, legs, and antennee fulvous ; clothed with 

 short greyish hairs. 



Antoiiue moderate, their basal joint stout, third about half the 

 length of the fourth. Head infuscate, broad, finely yet quite percep- 

 tibly punctured. Prothorax very transverse, nearly as wide at its 

 strongly sinuated base as the shoulders of the elytra, bisinuated in front, 

 the sides nearly straight, but narrowed anteriorly, very finely and dis- 

 tantly punctured, with an almost nude disc. Elytra moderately and 

 regularly convex, not at all depressed, rather coarsely and somewhat 

 rugosely punctured, less so behind ; they are quite green, with the 

 suture purphsh. Scutelhon punctulated, testaceous. 



Length, if; breadth, \^^ line. 



I found one example of this pretty, easily recognized species, at 

 Parua, near Whangarei Harbour.

 C. angustiihts, sat elongatus, evidenter pubescens. Sat nitidus, testaceus, 

 elytrorum sutura plus minusve infuscata; r«/'//^haud lato, crebrius granu- 

 lato, opaco ; antennis elongatis, minus gracilibus, articulo tertio parvo,

 fere opaco, basi rotundata, utrinque vix sinuata ; ^/^/m crebrius minus 

 fortiter punctatis, haud impressis.

This is another species which, " prime visu," greatly resembles the 

 European C. variabilis ; it is readily distinguished from C. ceqiialis by its 

 smaller size and narrower form and the distinct granulation of the thorax. 



This is another of Mr. Wakefield's captures at Christchurch.
