114 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [CoJroptera. 



mucronate, and with a second but more minute projection at the apex in front. 

 Posterior corbels concave, but without duplicate ciliae or lateral truncature. Tarsi 

 with dense brushlike soles ; the basal portion of the first 2 joints, however, is 

 olabrous ; 3rd joint deeply lobed. Claws shoi't and stout. Prosternum incurved in 

 front ; anterior coxae prominent and contiguous. Abdomen elongate ; 2nd segment 

 about as long as the basal at the sides, its frontal suture quite obsolete in the middle ; 

 3rd and 4th equal, not abbreviated, yet a little shorter than the 2nd ; 5th subconical. 

 From Catodryobius it is distinguished by the absence of any distinct mandibular 

 scar, by the entirely dift'erent scrobes, transversal eyes, and the partial exposure 

 of the pygidium, this last a very unusual character. 



Heterexis sculptipennis, sp. nov. 



Elongate, slightly nitid, quite black, legs and antennae piceous ; sparsely clothed 

 with depressed slender scales of a yellowish colour, and somewhat concentrated 

 towards the hinder portion of the elytra and there intermingled with setae. 



Rostrum about a fourth shorter than thorax, smooth and not in the least carinate 

 along the middle, rather finely and rugosely punctured towards the sides, the triangular 

 clypeus connate but quite definite, with 2 elongate spiniform conspicuous setae in 

 front. Head with a shallow, finely punctured, rugose impression close to each eye, 

 and a well-marked elongate central impression, nearly smooth behind. Thorax of 

 nearly equal length and breadth ; there are 2 median impressions, the frontal one 

 elongate, and 2 near each side, the one nearest the base somewhat rounded, the other 

 more shallow and larger ; the areas surrounding these are more closely, but not 

 coarsely, punctured than the middle of the disc ; basal margin a little thickened 

 towards each side ; it is obviously broader near the front than it is elsewhere. Scutel- 

 Imn rounded behind. Elytra slightly but quite definitely broader than thorax at 

 the base, oblong, their sides slightly rounded but a good deal narrowed posteriorly 

 and not covering the pygidium ; the suture is a little elevated throughout and smooth 

 along its basal half ; the 3rd and 5th interstices are costiform near the base but 

 more or less interrupted by transverse impressions further back ; they do not extend 

 beyond the top of the posterior declivity ; the 7th, which limit the sides, are similarly 

 raised as far as the hind thighs ; there are 2 ill-defined striae with coarse irregular 

 punctures between the suture and 3rd interstice on each elytron ; the 2nd interstice 

 is divided into short lengths by transverse impressions ; the sculpture between the 

 3rd and 5th and the 5th and 7th is nearly similar, all coarse and ill defined, so as to 

 produce a rough-looking surface. Femora much compressed near the base. Anterior 

 tibiae rounded at the extremity in front and only slightly angulate at the inner 

 side. There is no trace of ocxdar lobes in this species. The two outstanding dupli- 

 cate but connate spiniform setae at the extremity of the rostrum are remarkalsle. 

 The scutellum, is sublunate behind but vertical in front. 



Length (rost. inch), 8 lines ; breadth, 3 lines. 



Adams Island. 



Discovered by Mr. R. Speight. Another specimen, mounted on cardboard, 

 returned to Mr. (4. \ . Hudson after examination. 



Heterexis laeviusculus, Broun, 1901. 



Suhopaque, rufo-jjiceous, rostrum and thorax nigrescent ; very sparingly clothed 

 with slender decumbent setiform testaceous squamae.
