Antliribida; of New Zealand. 433 



of tlieir base so as to form the liincl angle of the thorax, which 

 is about a right angle ; it is continued at the sides not quite 

 halfway forward to the front ; this part of it, however, is but 

 little conspicuous. Elytra clothed with a fine black pubescence, 

 and on the middle wuth a small ash-coloured mark ; the basal 

 part of each near the suture is a little elevated, and the rest of the 

 surface is rather uneven with indistinct elevations and depres- 

 sions ; the rows of punctures are distinct, but not very regular. 

 The pygidium is moderately large ; and the penultimate dorsal 

 segment appears to be grooved in the middle for the apex of 

 the elytra. The legs are nearly black, except the tarsi, which 

 are reddisli. The anterior coxte are quite contiguous ; the 

 middle and hind coxa? are rather widely separated. The second 

 joint of the tarsus is but little distinctly emarginate ; the third 

 joint is small and cleft to the base, so as to consist of two 

 narrow lobes. 



Tairua (a single individual sent by Capt. Broun). 



The nearest described ally of this species is probably the 

 Dysnos semiaureus of Pascoe, from the Malay archipelago. , 

 The appearance of that species is said to be that of a Scolytid ; 

 Antlirihus crassus suggests to me rather the appearance of a 

 minute Chlamys-\\V.& insect. The fine pubescence, which forms 

 on the thorax and elytra indistinct pale spots, only strikes the 

 eye when a careful glance is directed to them. 



Anthribus nanus, n. sp. 



A. capite baud rostrato, oculis subconvexis, piceus, transversira con- 

 vexns, vix distincte tomentosus!, anteunarum basi, tarsisque rufo- 

 testaceis ; elytris superficie valde insequali. Loug. corp. If m. m. 



This species appears to be very closely allied to Antlirihus 

 crassus J but is smaller, and has the surface of the elytra much 

 more uneven, there being before the apex some elevations 

 which do not exist in A. crassus ] this uneveness of their sur- 

 face renders the lines of punctures very irregular. The pale 

 spots of fine pubescence seen in^l. crassus appear to be absent 

 in my individual of ^. nanus. 



Tairua. A single individual sent by Captain Broun ; it 

 shows me no indication of its sex. 



Antlirihus atomus, n. sp. 



A. capite nullo modo rostrato, ocuhs minoribus, sat convexis, 

 oblongus, transversim convexus ; protborace sericeo-opaco, im- 

 punctato, setis depressis paUidis parce vestito ; elytris fere nudis, 

 striatis, striis indistincte punctatis. Long. corp. 1 m. m.
