OF NEW ZEALAND. 1087 



the dorsum is covered with small granules or rounded tubercles, it is 

 uneven, with a rather deep, almost smooth, median depression 

 having raised borders, the elevations are irregular. Elytra with 

 several series of small rounded elevations or granules, rather irregu- 

 lar however ; there are, on each elytron, three eloiagate basal eleva- 

 tions, and, in line with the sutural one, near the top of the hind 

 slope, there is a shorter, more nodiform one, besides two or three 

 smaller nodosities behind. Tibice nearly straight, the anterior with 

 small but distinct spurs ; tarsi with the intermediate joints equal. 



Underside more or less granulate. 



Very much like No. 1662, which must be placed in this genus, 

 instead of being called Coxelus grossanus. 



Length, If lines ; breadth, nearly f line. 



Moeraki. One example, from Mr. Sandager. 



Vitiacus. 



Nov. ijcn. 



Body elongate-oblong, narrowed posteriorly. Head exserted, 

 forehead truncate. Eyes small, convex, with coarse facets. An- 

 tcnncB 11-aniculate, club abruptly biarticulate ; basal joint con- 

 cealed above by large setigerous prominences ; second stout ; third 

 much smaller, not elongate, yet distinctly larger than the following 

 ones ; joints 4-8 small, nearly equal ; ninth slightly broader than the 

 eighth. The antenna, in repose, is received into a groove below 

 the eye, as in Coxehcs, but, as is not the case in that genus, the 

 remaining joints are accommodated in a large cavity of the pro- 

 sternum near the side and front. Thorax with the dorsum trans- 

 versely convex, this portion as wide as the head ; the sides deeply 

 and broadly hollowed, with refiexed margins ; anterior angles pro- 

 minent but obtuse, the posterior rectangular. Scutellum minute or 

 invisible. Tarsi narrow, their fourth joint as long as the other 

 three taken together, the basal rather larger than the intermediate 

 ones, singly. Epipleurce broader than in Coxelus, not narrow till 

 very near the extremity. 



The above indicate the principal differences between this genus 

 and Coxelus. Chorasus is distinguishable by the structure of the 

 antennge. 



1937. V. COStatuS, ii'-s. Elongate-ohloiKj , transversely convex, 

 rough-looking, sparsely clothed with slender fulvous setge ; opaque, 

 fuscous, the sides of the thorax, the legs and antennoe, of different 

 shades of red. 



Head covered with rather large, flattened, granular elevations, 

 with a well-marked transverse groove behind, and another about 

 midway between the centre and each side. AntenncB shorter than 

 the thorax, club densely and finely pubescent. Thorax rather 

 broader than long ; apex emarginate near each side, more setose at 

 the middle than elsewhere ; the disc with a short longitudinal 

 depression, and numerous granules, which are larger than those on 



8 — PT. V.
