line with the front of each eye. Thorax with a fine dorsal line, almost 

 smooth, yet sculptured very much in the same way as the head ; it is a 

 little convex, and bears an obvious bristle at each side where angulated ; 

 it is peculiar in form, the anterior rim is fine, continuous with the lateral, 

 and both seemingly define the actual shape, this is the case with the 

 upper portion only, the side margins converge near the base, become 

 obsolete towards the middle, and are separated by a very finely striate 

 space \ the true base, however, is quite distinct from the apparent, 

 without the least trace of hind angles, but with a much finer, acute line 

 below the other defining its real outline. The elytra are rounded 

 (singly) at the base, without the slightest trace of humeral angles ; they 

 are very little curved laterally, and the apices are a little sinuated 

 towards the suture, where they are slightly but obtusely produced ; they 

 are a little wider behind than elsewhere, bear shallow, almost impercep- 

 tibly punctate striae, are somewhat rugosely sculptured at the sides, and 

 their whole surface exhibits pretty much the same dense but very fine 

 sculpture observable on the head and thorax ; the vittse are distant from 

 the suture in front, but occupy most of the posterior space, and the 

 suture is sometimes reddened.

I have dedicated this peculiar form in honour of a gentleman (C. 

 M. Wake.field) to whom the scientific workers of New Zealand are much 

 indebted. I found four examples in different localities.

This genus differs from Coptodera by the form of the tooth of the 

 mentum, which is notched ; the labrum is shorter ; and the antennae are 

 thicker at the extremity. 



Coptodera. Mentum deeply emarginated, with a single strong 

 median tooth. Ligula very large, slender, horny ; its paraglossse wide, 

 membraneous. Last joint of the palpi slightly oval, and almost acumi- 

 nated. Mandibles rather prominent, feebly arcuated at their extremity. 

 Labrum elongated, a little narrowed in front, and slightly rounded, or 

 truncated. Head short oval, a little narrowed behind. Eyes large and 

 prominent. Antenna subfiliform, a little longer than head and thorax, 

 their joints equal, save the second, which is shorter than the others ; the 

 first rather stout. 



Prothorax transversal, strongly cordiform, margined laterally, its 

 angles more or less prominent. Elytra depressed, wide, not edged, 

 obliquely sinuated and truncated at their extremity. Legs moderate, a 

 little robust ; tarsi filiform, the first four joints of the anterior slightly 

 triangular, fourth entire, the claws denticulated. 



Body more or less broad and flattened.
