116 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Cokoptera. 



diameter being from above downwards ; their 3rd tarsal joint is formed of very 

 elongate and evidently separated lobes ; the prosternum is more deeply and abruptly 

 eniarginated ; the elytra are closely adapted to the thorax, and at the base do not 

 exceed it in width ; the rostrum is nearly cylindrical throughout, whereas in Hycanus 

 the anterior two-thirds is of oviform outline, and the smooth apical portion is not 

 limited behind by any definite suture. 



Hycanus cockaynei, Broun, 1905. 



Suhovate, slightly convex, opaque ; fuscous ; apex of thorax, elytral suture, 

 and legs castaneous ; antennae rufescent ; tarsi testaceous ; very sparingly clothed 

 with rather fine short grey setae, on the hind-body, however, many longer erect 

 ones occur. 



Rostrum rather coarsely punctate, but smooth, shining, and reddish near the 

 extremity ; this part bears a few slender white hairs, but is not marked off from 

 the asperate portion by any basal suture ; on the head there is a feeble longitudinal 

 interocular furrow. Thorax slightly longer than broad, widest near the front, slightly 

 constricted at apex, gradually narrowed behind ; it is not uneven, there being only 

 a short groove in front ; its whole surface is densely and minutely sculptured, and 

 the visible punctures are only moderately coarse. Elytra oblong-oval, much nar- 

 rowed posteriorly ; they are punctate-striate on the disc ; towards the base and 

 sides the punctures are distinct, but the striae are not ; the interstices are plane and 

 minutely and closely sculptured. Antennae sparsely pubescent. 



Underside with a few small grey setae ; the prosternum with some coarse shallow 

 pimctures, the ventral segments finely sculptured.

Auckland Islands. 



Described from one example found amongst moss in July, 1903, by Dr. L. 

 Cockayne, in whose honour it has been named. The specimen was forwarded to me 

 by Professor Chilton. 



Hycanus frontalis, sp. nov. 



Rostrum longer than thorax, somewhat pterygiate just before the middle, so that 

 the scrobes are open above at that point, its frontal portion deflexed, nearly smooth 

 and shining, almost truncate at apex ; its hinder portion distinctly narrowed back- 

 wards, the punctuation rather shallow ; a triangular impression, with almost carinate 

 borders, occupies most of the basal surface. Eyes flat, oblique, with coarse facets. 

 Thorax of about equal length and breadth, a little wider before the middle than it 

 is elsewhere, slightly narrower at the front than behind, apex truncate, base sub- 

 marginated ; its surface closely and minutely sculptured, and with rather irregular 

 coarse shallow punctures which are sometimes hidden by sappy matter, the dorsal 

 groove interrupted in the middle and rather broader near the base than in front, 

 ScuteUum absent. Elytra elongate, base obliquely truncate towards the suture 

 slightly wider than thorax there, shoulders a little rounded, sides nearly parallel 

 apex considerably narrowed ; the entire surface minutely and densely sculptured 

 and bearing a few erect testaceous setae ; they are evidently regularly striate-punc 

 tate. Body subdepressed, opaque, fuscous, legs and antennae dark-reddish, tarsi 

 paler but somewhat variegate, the deflexed frontal portion of rostrum pitchy-red.
