Broun. — Revision of the New Zealand Cossonidse. 181 



Attarus tristis, sp. nov. 



Angustate, dark piceo-rufous, legs rather lighter, antennae fulvescent ; 

 slightly nitid, pubescence greyish-yellow. 



Eostrum shining, rufescent, distantly and finely punctured in front, 

 nearly smooth along the middle, the punctuation becoming coarse, somewhat 

 elongate and rugose on the vertex ; the occiput also with some distant 

 punctures. Eyes much less prominent than in Pentarthrum. Thorax un- 

 impressed ; very coarsely, closely, and rugosely punctured at the sides ; 

 the disc less coarsely and closely, on the middle especially, more closely in 

 front ; the apical margin, however, is smooth, and of a somewhat metallic 

 reddish-coppery hue. Elytra a good deal narrowed at the posterior declivity, 

 the apical margins rufescent and evidently rounded singly ; they are regu- 

 larly and distinctly but not coarsely striate-punctate, quite striate behind, 

 the suture and interstices finely seriate-punctate and slightly rugose. Legs 

 with minute yellowish setse, most conspicuous along the inner face of the 

 front tibiae.

A. castus, Broun. 1307. Man. N.Z. Coleopt., p. 736. 



This species must be detached from Pentarthrum. The rostrum is rather 

 longer than that of A. tristis, similarly sculptured and narrowed behind, 

 but along each side it bears several slender outstanding yet not very elongate 

 setae. Occiput smoother and more convex, and therefore more distinctly 

 marked oft" from the close interocular punctuation. Disc of thorax very 

 slightly and indistinctly flattened ; the slender yellow hairs on its sides 

 are quite easily seen. Scutellum small and seemingly bent downwards in 

 front, instead of being horizontal. Elytra with more distinct and closer 

 interstitial punctures ; those in the striae are more quadrate, and are sepa- 

 rated by short intervals only ; the yellow hairs are more numerous.

A. vestitus, Broun. 916. Man. N.Z. Coleopt., p. 514. 



Body dark piceo - rufous, tarsi and antennae red, club fulvescent ; 

 pubescence distinct, yellow, rather elongate and slender. 



Rostrum rather broad, incurved behind the middle ; rather coarsely, 

 relatively, punctured and longitudinally rugose, the punctures not as close 

 on the head ; the occiput also wath a few punctures. Thorax with the 

 median line smooth, coarsely and rugosely punctured, more closely at the 

 sides than on the disc, very closely near the smooth coppery front margin. 

 Elytra subpunctate-striate, quite striate behind and at the base ; the suture 

 and interstices finely seriately punctate and slightly rugose. 



Underside shining, rufo-piceous, with minute setae along the middle 

 of the breast, but on the abdomen and along the sides the setae are more 

 elongate and obvious ; the punctuation on the sides, the front of the pro- 

 sternum, and on the basal 2 ventral segments is coarser than alone: the 

 middle of the sternum ; base of presternum transversely rugose and 

 punctate. 



Prosternum truncate in front. Rostrum medially grooved underneath, 

 the groove with sharply defined borders. Buccal cavity large. Meta- 

 sternum elongate, rather shorter than the abdomen, medially sulcate. Basal
