COLEOPTERA 



eleven, ten, or nine joints, the two first long and thicker than the 

 following joints, the two last forming a small club, the antepenultimate 

 thicker than the preceding joints, transversal. Prothorax cordiform, 

 variably grooved above. SciitcUiim small, curvilinearly-triangular. 

 Elytra oblong-oval. Legs moderate ; tarsi short, first and second joints 

 small, equal, third as long as the first and second taken together. 

 Body oblong, smooth, winged. 



40S. H. lUCidUS, n.s. Rather elongate, elliptical, shining, of a 

 brick-red colour, finely and sparsely pubescent; legs testaceous; antennte 

 reddish or testaceous. 



Antennce moderately stout, eleven-jointed, the two basal joints about 

 equal in length, the first the stouter, the second nearly as long as the 

 third and fourth, united ; fifth nearly as long as the second ; ninth a 

 good deal larger than the preceding one ; the tenth and eleventh 

 forming a rather large obtuse club. 



Head very finely and remotely punctulated. Prothorax cordate, 

 margined, convex, much wider in front than behind, and Considerably 

 constricted near the base, in front of which there is an obvious trans- 

 verse depression terminating at each side in a distinct fovea, and along 

 the basal margin there is a row of punctiform impressions ; the surface 

 is almost imperceptibly punctulated, and, like the head and elytra, 

 sparingly clothed with excessively fine hairs. ScitteUiim almost semi- 

 circular. Elytra moderately elongate, obovate, wider than and about 

 twice as long as the thorax, widest in front of the middle and somewhat 

 convex ; each bears a distinct sutural stria, between the suture and stria 

 a series of small punctures, and the rest of the surface is more or less 

 finely punctulated. Legs of moderate length ; femora incrassated ; tibtcz 

 nearly straight but a little expanded apically, the third tarsal joint not 

 longer than the other two. Under-side a little paler than the upper, 

 punctulated and clothed in a similar manner. 



Anterior coxie almost contiguous, the posterior most widely separated. 

 Metasternuni large. 



Length, f line. 



I found several specimens of this species at Auckland, Tairua, and 

 in the vicinity of Whangarei Harbour.

Mentum transversal, dilated and truncated in front ; ligiila narrower, 

 horny, with a membraneous border in front, and its angles ciliated ; 

 internal lobe oi\\vtjaws replaced by a bunch of hairs, the external lobe 

 wide at its base, terminated by a slender point, long and arched. 

 Labial palpi with two joints, the first slightly distinct, second very 

 thick, sub-globular, truncated and ciliated at the end ; last joint of the 

 maxillary palpi rather longer than the two preceding joints taken 

 together, conical. Mandibles small, ciliated internally, and simple at
