OF NEW ZEALAND. 783 



1394. H. nigrescens, n.s. Shining, brownish-black; legs and 

 four basal joints of antennas pale-testaceous ; clothed with semi- 

 erect pallid hairs ; moderately elongate, sub-depressed. 



Head broad, quite as broad as thorax, forehead with two rounded 

 foveae, its surface glossy, nevertheless finely linearly sculptured; 

 eyes large and prominent, causing the head to appear unusually 

 broad. Antenna elongate, considerably longer than head and thorax, 

 stout, basal joint incrassated apically, second short but stout, fourth 

 rather smaller than third or fifth, eleventh elongate-oblong. Pro- 

 thorax broader than long, base and apex truncate, strongly rounded 

 laterally, impressed transversely in front and behind, the basal im- 

 pression bent and terminating in a deep fossa near the middle of 

 each side ; very densely sculptured, apparently minutely granulated, 

 the granules, however, flattened above. Elytra broader than thorax, 

 widest behind the posterior femora, transversely punctate-rugose. 

 Legs moderate ; tarsi shorter than tibiae, their fifth joint twice as 

 broad as the others, not so long as they are conjointly. Claws ap- 

 pendiculate. 



Length, i lines ; breadth, f . 



I found only one at Waitakerei. 



1395. H. brevicornis, n.s. Black, glossy, legs and labrum 

 castaneous, antennae piceous. 



Head rather small, indistinctly bi-impressed in front, its sculp- 

 ture dense but indefinite, seeming to consist of minute depressed 

 granules. Prothorax transversal, narrower in front than behind, 

 indistinctly impressed on the middle of the apex transversely, more 

 so on the sides, the basal depression bent forward and ending in a 

 cavity near the middle at each side ; its whole surface is excessively 

 finely sculptured, but with many quite evident though rather shallow 

 punctures. Elytra broader than thorax, gradually dilated pos- 

 teriorly, transversely punctate-rugose. Legs moderate. Antenna 

 short, as long as head and thorax, third articulation a little longer 

 than fourth, joints 4-10 sub-quadrate; eleventh oval, longer than the 

 preceding ones. 



Broader than the typical species ; the eyes being smaller causes 

 the head to appear narrower ; the antennae are decidedly shorter, 

 and their last joint quite oval and pointed ; and the fifth tarsal joint 

 is not quite so much expanded towards the extremity. 



Length, i J lines ; breadth, f line. 



One, from Waitakerei. 



1396. H. semidilutus, n.s. Elongate, sub -depressed, rather 

 densely clothed with fine greyish hairs, shining-black ; elytra infus- 

 cate-black, with the suture and apices testaceous, as are also the legs 

 and first four antennal joints. 



Head minutely and densely granulated. Prothorax transverse, 

 of the normal form, its sculpture similar to that of the head. 

 Elytra punctate, becoming transversely punctate-rugose laterally. 



A variable species : sometimes the whole of the elytra are suffused 

 with testaceous. My three specimens are in bad condition, so that 

 it is not advisable to enter into structural details,
