440 COLEOPTERA. 



Rostrum {)unctat(\ with a distinct carina from its base to the antennae,, 

 tricarinate between these, rufescent in front. Thorax a fifth longer than 

 broad, moderately coarsely and closely punctate, the intervals more or 

 less rugose, finer in front. Elytra nearly double the length of thorax, their 

 sides almost straight to beyond the posterior femora, moderately narrowed 

 behind, their obtuse shoulders slightly porrect, 3rd and 5th interstices ob- 

 tusely elevated near the base ; they are finely and definitely striate beliind, 

 but the dorsal sculpture being obscured by a film of sappy matter is rendered 

 indistinct ; when the surface is scraped with the point of a needle, and 

 looked at from above, there seem to be series of punctures — these, how- 

 ever, when carefully examined sideways appear to be transformed into 

 granules, as is often the case in some of the Colydiidae, in the genus Coxelus 

 especially. 



Underside nigrescent, sparingly setose. Basal ventral segment broadly 

 impressed along the middle, more coarsely but less closely punctured than 

 the 2nd. the punctation of the 5th is shallow. The thick palpi are quite 

 visible beyond the nientum. 



Thorax witli a fine carina which becomes indistinct towards the base. 



Length (rostrum inclusive), 51 mm. ; breadth, 1| mm. 



Mount Dick, near Lake Wakatipu. Two detected amongst dead leaves 

 on the ground, at a height of 3,500 ft., bv Mr. T. Hall on the 17th March, 

 1914.

 p. 1474. 



Elongate, transversely convex, subopaque ; with a few fine, pale, 

 inconspicuous setae ; fusco-rufous, rostrum paler, antennae and tarsi 

 fulvescent. 



Rostrum rather shorter than thorax, gradually and sHghtly narrowed 

 anteriorly, its apical portion smooth and shining, elsewhere dull, with dense 

 minute sculpture, nearly plane or only feebly grooved along the middle. 

 Thorax nearly a third longer than broad, suboviform, widest before the 

 middle, nearly straight behind, a good deal but not abruptly contracted 

 in front ; the channel along the middle broad, not very deep, sometimes 

 indistinctly divided lengthw^ays, at each side of this, near the middle, there 

 is a small elevation and another can be seen near the base, its punctation 

 is shallow and somewhat irregular. Elytra nearly double the length of 

 thorax, slightly wider than it is at the base ; each with 5 dorsal series 

 of relatively large, suboblong punctures, the sutural indistinct ; interstices 

 subcarinate, the 1st throughout, the others more or less abbreviated 

 behind, the suture also slightly elevated. 



Antennae normal, with slender greyish hairs. 



<^. Legs stout, posterior tibiae cihate inwardly, incrassate above the 

 middle. Tarsi short and narrow, penultimate joint not expanded, slightlv 

 excavate above at the apex, the terminal fully as long as tlie basal 3 

 combined, with nearly straight claws. 



Underside indistinctly punctate, with a few fine setae. Anterior and 

 intermediate coxae very prominent, the latter distinctly separated, the 

 posterior widely. Metasterinim large. Basal segment of abdomen broadly 

 depressed, 2nd considerably shorter, the suture between these quite dis- 

 tinct and sinuate in the middle, the 2nd widely emarginate behind. 



Fern. — Tibiae nearly straight, the posterior without cilia.
