Female. — Rostrum rather longer, but not appreciably more slender. 

 Thorax different, widest near the base, gradually narrowed from that point ; 

 posterior angles quite oblique. Apt to be mistaken for a distinct species. 



Belka spadicea, Broun. 1628. Man. N.Z. Coleopt., p. 911. 



Subopaque, rostrum and elytra slightly nitid, fusco-castaneous, legs of a 

 chocolate colour, antennae and tarsi piceo-rufous, pubescence more abundant 

 on the elytra than on the thorax. In the male the elytra are somewhat 

 rufescent. 



Rostrum moderately finely and not closely punctured throughout. 

 Head pubescent, moderately punctate ; occiput not quite smooth. Scape 

 glabrous, the funiculus finely and sparingly setose. Club densely and finely 

 pubescent, slightly annulate. Thorax with a smooth median line, mode- 

 rately finely and not closely punctured, disc convex, frontal constriction 

 deep. Elytra as broad as the widest part of thorax, their striie rather 

 shallow, crenate-punctate, the punctuation becoming indistinct behind, 

 interstices rugose and seriate-punctate. 



Underside rufo-piceous, slightly nitid, the whole derm densely and 

 minutely sculptured, the setae greyish and slender but numerous, the 

 punctuation moderately coarse but not close.

Dunedin. One of each sex. 



Attarus, gen. nov. 



Elongate, fusiform-cylindric, slightly transversely convex, a little shining, 

 sparingly clothed with slender but quite perceptible pubescence. 



Rostrum porrect, a little arched in front, rather shorter than thorax, 

 slightly narrowed behind, in front more than half the width of the head. 

 Scrobes linear, directed obliquely towards the lower and inner part of the 

 eyes. Scape elongate, only moderately stout, inserted at or before the 

 middle, and attaining the front of the eye. Funiculus elongate, basal joint 

 large, 2nd not distinctly longer than 3rd, 4th and 5th short. Club ovate, 

 stout, not articulated. Head rather short, moderately globose, the occiput 

 curvedly narrowed towards the eyes, but not constricted or marked off in 

 front. Eyes rotundate, only slightly prominent, lateral. Thorax longer 

 than broad, widest behind the middle, well rounded there, a good deal 

 narrowed and constricted near the front, base truncate. Scutellum minute. 

 Elytra subtruncate at the base, as broad as the widest part of the thorax, 

 gradually narrowed posteriorly, their apices individually rounded. Legs 

 relatively rather slender ; tibiae straight and hardly at all expanded, 

 uncinate ; tarsi stout, the terminal joint quite the length of the basal 3 

 united, 3rd a little expanded, widely concave in front, not distinctly lobate, 

 apparently entire underneath. 



Prosternum incurved in front, the coxae more approximated than in 

 Pentarthnim. The metasternum elongate, nearly as long as the abdomen, 

 finely medially sulcate, 2nd ventral segment shorter than 1st, their suture 

 distinct and undulate. 



The structure of the antennae and tarsi, irrespective of other charac- 

 teristics, is enough to prevent the association of the type of this genus with 

 Eucossonus. It cannot be referred to Agastegnus, which is composed of 

 depressed, long-legged insects. Sericotrogus has an entirely different head. 

 &c., and the other Pentarthrum allies also exhibit disparities.
