the front of the eye. Funicukis 5-articulate, 2nd joint slightly longer than 

 3rd, joints 3-5 subqnadrate. Club oblong-oval. Head rather short, globose 

 underneath, slightly constricted just behind the very prominent eyes. 

 Thorax triangular-ovate, evidently constricted in front. Scutellum small. 

 Elytra incurved at base, slightly rounded singly at the apices, parallel- 

 sided, rather broader than thorax at the base. Legs moderate, 3rd tarsal 

 joint small, excavate but not distinctly lobed. 



Underside shining, rufo-piceous, sparingly and minutely pubescent, 

 coarsely punctate, terminal segment less distinctly. Anterior coxse less 

 distant than in Pentarthrum, further apart than those of Sericotrogus. 

 Mesosternal suture distinct, truncate between the coxae. Metasternum 

 moderately elongate, medially sulcate. Basal ventral segment broadly 

 impressed in the middle, sloping downwards towards the 2nd, the inter- 

 vening suture subtruncate and well marked, the terminal bent upwards 

 yet hardly reaching the level of the epipleurae, with a round median im- 

 pression ; it is rufescent. 



The type of this genus cannot remain in Sericotrogus, on account of the 

 unlobed tarsi, more widely separated coxae, different head, &c. The superb 

 vestiture, more convex and prominent eyes, and the slight sexual differen- 

 tiation of the rostrum show that it cannot be located in Pentarthrum. A 

 new genus therefore is instituted for its reception. 



Gaurocryphus auricomus, Broun. 1302. Man. N.Z. Coleopt., p. 733. 



(Plate XV, fig. 13.) 



Piceo-rufous, moderately shining ; with the exception of the apical 

 half of the rostrum, thickly covered with decumbent, elongate, beautiful 

 yellow hairs ; in the female some of the elytral pubescence is greyish. 



Rostrum distinctly longitudinally rugosely punctate almost to the 

 extremity ; vertex also moderately coarsely punctured, the short occiput 

 finely. The eyes are distinctly convex. Thorax with moderately rounded 

 sides, gradually narrowed from the middle towards the frontal constriction, 

 which is only slight in the female ; disc slightly convex, moderately coarsely 

 and closely punctured almost to the apical margin. Elytra punctate-striate, 

 the grooves, however, rather shallow ; interstices and suture with serial punc- 

 tures, the pubescence, however, renders the sculpture somewhat indefinite. 



Female. — Rostrum rather longer, quite stout, slightly but widely nar- 

 rowed behind the middle and again a little expanded towards the eyes. 

 Antennae medially inserted.

Tairua (one female), Waitakerei Range (one male). 



Eucossonus, Broun. Man. N.Z. Coleopt., p. 870. 



Elongate, subdepressed, the whole surface dull, with dense minute sculp- 

 ture, and clothed with distinct yellow hairs or setse. 



Rostrum rather shorter than thorax, the basal half narrower than the 

 frontal, arched above ; more slender in the female. Scrobes narrow near 

 the apex, expanded, and reaching the eyes. Head short, occiput much 

 narrowed and constricted in front. Eyes moderately convex, subtruncate 

 behind, and extending considerably downwards. Scape slender, elongate 

 and flexuous, inserted before the middle, and almost reaching the thorax. 

 Funiculus elongate, laxly articulated, the basal 2 joints of about equal 

 length, joints 3-5 submoniliform. Club oblong-oval. Thorax longer than 

 broad, deeply constricted near the front, so that the apex seems dilated,
