middle for the insertion of the antenu£e, at that point approaching 

 Otiorhynclms in appearance ; the scrobes, therefore, are visible from 

 above for nearly half their length. 



1417. H. argentatUS, "-s. Piceous; legs and antennas pitchy- 

 red ; covered with depressed, oval, whitish and pallid scales. 



Bostrum nude and nearly smooth in front, slightly widened 

 at the end, its basal half squamose. Prothorax convex, its length 

 and breadth about equal, rounded laterally, almost constricted 

 in front ; punctured rather coarsely and closely. Elytra broader 

 than thorax, shoulders oblique, sides nearly straight, contracted 

 and declivous behind, nearly plaiie above ; each elytron with 

 three more or less obvious costae, the intermediate ceasing at 

 the others before the posterior declivity, with two rows of coarse 

 and distant punctures on the interstices ; the scales are of a 

 silvery hue, except along the suture and elevated parts, where 

 they are intermingled with a few coarse bristles and of a pallid 

 colour. Legs covered with scales and set®. Antenna reaching 

 backwards beyond the base of the elytra, hirsute, their second 

 joint twice as long as the third, the latter shorter than the first. 

 Underside punctate and squamose, in colour resembling the upper 

 surface. 



Length, 3|— 3f lines (rost. excl.) ; breadth, i^if . 



I captured my three specimens on the Waitakerei Kange. 



Dorytomus (p. 453)- 



141S. D. aericomus, "-s. Elliptical, elongate - oval, 

 slightly convex; flavo - testaceous; most of the thorax and on 

 the elytra a large tri-lobed basal spot, an irregular, interrupted 

 median fascia, a lateral stripe and sub-apical spot, nigro-fuscous ; 

 scape and tarsi testaceous-red, beak and funiculus infuscate-red ; 

 clothed with decumbent brassy hairs. 



Rostrum moderately elongate, arched, parallel, quadri-sulcate. 

 Head punctate, densely covered with yellow hairs ; eyes somewhat 

 prominent, distinctly facetted. Antennce elongate, scape slender 

 and gradually thickened ; funiculus with fuscous hairs, basal 

 joint largest, much incrassated tov/ards the extremity, second sub- 

 cylindric, shorter than third and fourth conjointly, these latter equal, 

 longer than broad ; joints 5-7 decrease in length, the last trans- 

 verse ; club oblong-oval, pubescent. Prothorax transversal, rounded 

 laterally, narrower in front than behind ; not closely nor coarsely 

 punctured, its clothing disposed across the surface. Scutcllum 

 small, blackish. Elytra nearly thrice the length of the thorax, a 

 good deal broader than it at the base, humeral angles oblique ; 

 they taper gradually towards the apices, are striate-punctate, the 

 interstices plane and minutely punctulated, the fourth and seventh 

 unite before the apices, and at their junction appear somewhat 

 elevated, just where the dark apical spots bend towards the sides ; 

 their hairs arranged lengthways. Legs stout ; femora dilated and 

 angulated, dentate, so as to appear deeply notched at the extremity ; 

 tibiae flexuous.
