and ocular punctures. Prothorax quadrate, slightly rounded laterally, 

 gradually narrowed till near the base, where it is somewhat suddenly con- 

 tracted, so that the posterior angles are quite rectangular, but not acute ; 

 the surface presents many fine transversal striolae; the median groove ter- 

 minates in fovea-like expansions near the base and apex, but does not 

 reach either ; the two basal fossae are deep, but not very broad ; the im- 

 pressions near the anterior angles are tolerably distinct, and there are 

 three or four punctures along the side-channels. Elytra oblong-oval, but 

 little convex, a good deal sinuously narrowed towards the apices, their 

 shoulders somewhat protuberant; their seven discoidal striae are tolerably 

 deep, and their punctation rather irregular, consisting of small and 

 oblong punctures, which, however, are more conspicuous towards the 

 extremity ; between the eighth stria and the sides there is an interrupted 

 row of catenulate punctures becoming confused behind; the intervals 

 between the furrows are of nearly equal width, a little elevated and 

 entire, but the punctation of the striae is here and there interrupted. 



Under-side glossy pitchy-black. 



In the form of the thorax this specimen resembles H. hispidulus 

 (p. 40), having the same apical and basal emarginations but finer lateral 

 margins, and may be distinguished from it by the presence of depressions 

 near the front angles ; in the sculpture of the elytra it approaches H. 

 elongella and H. ovatella, but it cannot well be confounded with either, 

 the thorax in the latter species, though quadrate, being short, the sides 

 forming an almost uninterrupted curve towards the obtusely rounded pos- 

 terior angles. 



In my specimen of the female sex the thorax is more glossy, the 

 elytral sculpture stronger, and the elytra rather narrower than in the male. 

 The broadest part of the body is near the middle of the elytra. 



Length, 6^ lines ; breadth, about 2\. 



The pair I possess were found in the forests near Whangarei Heads. 



1148. H. thoraciCUS, n.s. Oblong, sub-depressed, deep shining 

 black ; three basal joints of the antennae pitchy-black, the remainder 

 obscure rufous ; tarsi and palpi pitchy-red. 



Head moderately large, smooth behind the frontal impressions, with 

 two punctures close to each eye. Prothorax quadrate, broader than 

 long, apex not incurved, with rounded sides, sinuously narrowed behind, 

 widest at the middle, and with somewhat prominent posterior angles ; 

 its dorsal furrow, though well marked, does not reach the base or apex ; 

 the basal fossae are supplemented by distinct but smaller foveae near each 

 hind angle; the frontal impression is distinct, and the disc exhibits many 

 transverse aciculate impressions. Elytra scarcely broader than the 

 thorax, oblong, very gradually rounded laterally, though narrowed a little 

 towards the projecting humeral angles, sinuously narrowed apically, 

 and a little convex ; their seven dorsal striae are moderately but dis- 

 tinctly impressed, the intermediate pairs unite before the apex; their 

 punctation, though fine, is distinct and quite regular until the apex is 

 approached, at that part the punctures become obsolete ; the sides beyond 

 the eighth stria have a row of catenulate punctiform impressions. The 

 legs are rather short and robust ; the posterior femora dilated to beyond
