Coleoptera from Xew Zealand. 299 



Erymneus prohus, sp. n. 



Ohlong-oval or nearly so, dull black ; clothed with small 

 rust-red scales, those near the elytral suture quite minute, 

 the raised parts with squaraiform seta; near the suture, in 

 line with the hind thighs, there are two obvious oblique 

 yellowish crests; antennfe and tarsi rufo-piceous. 



Rostrum covered with sordid tawny squamjB, these some- 

 times form four small crests near the antennal insertion 

 (before the middle) ; the costaj are indistinct. The scape 

 reaches the middle of the eve, it bears fine, depressed, brassy 

 setas. T\\ii funiculus with the second joint quite as long as 

 the first ; seventh large, slightly broader than sixth, nearly 

 twice its length; cluh short, ovate, indis'inctly annulate. 

 Thorax with coarse shallow punctiform sculpture, about as 

 long as it is broad ; the central ridge extends to the large, 

 basal depression, the oblique ridge near each side becomes 

 obsolete behind the middle, Elijtra oblong, base deeply 

 emarginate, so that the shoulders extend forwards, the 

 sutural region depressed in front ; there are two rows of large 

 punctures along each side of the suture, outside these the 

 surface is uneven, on each side between the middle and hind 

 thighs there is a squamose prominence ; on the top of the 

 nearly vertical apical portion the third interstices are quite 

 prominent, at each side, but lower down, there is a still larger 

 elevation ; a few minute black tubercles are distributed over 

 the surface. Legs with coarse curled setee. 



Prosternum emarginate in front. Ahdomen rather flat, 

 coarsely punctate, with narrow ferruginous scales ; first and 

 second segments connate, thrice the length of the meta- 

 sternum. 



Most nearly allied to No. 2131, and most likely only a 

 varietal form thereof. 



Length (rostr. inch) 3^, breadth \\ lines. 



Mount Pirongia, December 1892. 



Ar^oscapus, gen. nov. 



Body rather narrow, without coarse squam® and tuber- 

 cular elevations. Rostrum rather slender, arched, longer than 

 thorax. Scroles foveiform at the point of antennal insertion 

 (before the middle), behind this a broad groove extends to 

 the eye, and in front another groove is directed obliquely 

 upwards, but does not reach the apex. Scape rather slender, 

 its extremity clavate ; it is nearly glabrous and somewhat 

 bent near the base, it attains the front of the eye. Funiculus 

 7-articulate, finely pubescent, its two basal joints about
