642 COLBOPTBRA. 



behind. Head narrowed anterioi'ly, its punctation moderately coarse but 

 shallow ; there is an elongate impression between the nearly flat eyes. 

 Thorax a little longer than broad, truncate at base and apex, slightly 

 broader near the front than behind, the sides very gradually narrowed 

 backwards, more distinctly in front ; disc coarsely and irregularly punc- 

 tured, with narrow rugose intervals, its central channel moderate, a little 

 deeper near the apex than elsewhere. Scutelluni invisible. Elytra elongate- 

 cordate, twice the length of thorax, very slightly wider at the base than 

 it is, gradually narrowed and curvedly deflexed posteriorly ; their striae 

 are shallow and broad but not very definite, and apparently imjjunctate ; 

 second interstices a little elevated near the base, third rather farther back, 

 all are more or less minutely asperate or uneven. 



Scape with a few pale setae, very gentlj'' incrassate, almost touching 

 the thoracic apex ; basal two joints of the funicle moderately and equally 

 elongate but, together, barely half the length of the scape, 3-7 successively 

 shortened ; club moderately elongate, triarticulate. 



Tibiae flexuous, the anterior slightly mucronate, the others indistinctly so. 



Underside nitid, piceo-rufous, with some depressed grey setae. Meta- 

 sternum and first ventral segment obviously depressed, distinctly and mode- 

 rately coarsely punctate ; second shorter than first, their suture sinuate, 

 fifth nearly double the length of third and fourth combined, truncate at 

 apex, punctate and .coarsely transversely rugose ; sixth short and broad, 

 more finely but longitudinally rugose. 



The rostral carina, antennal structure, peculiar ventral sculpture, and 

 the slight tibial mucro, even of the anterior, in the male, are its principal 

 characters. The setae are not concentrated in patches on the elytra as 

 is the case in the type of the genus, C. gracUipes (2138), and its close albes,- 

 and in the sole example before me the setae are just a little closer near 

 the sides than on the disc. 



(J. Length (rostrum exclusive), 5 mm. ; breadth, If mm. 



Upper Hutt. One, from Mr. A. C. O'Connor, on 21st August, 1916. 



4221. Clypeorhynchus furvus sp. no v. 



Subo])aque, moderately elongate and convex ; fuscous, antennae and 

 last two joints of tarsi pale fusco-rufous ; sparingly and irregularly clothed 

 with flavescent, suberect, scale-like setae. 



Rostrum a third shorter than thorax, dilated before the middle, deflexed 

 and almost smooth in front, finely tricarinate behind. Head short, broadly 

 impressed between the subrotundate, nearly flat eyes. Thorax of equal 

 length and breadth, only slightly wider before the middle than behind, 

 apex truncate, base feebly curved ; its punctation coarse, with slightly 

 rugose interstices, discal channel moderately deep in front and behind. 

 Scutellum obsolete. Elytra oblong-oval, narrowed and subvertical behind, 

 just double the length of thorax, very little broader than it is at the base, 

 nearly a third broader before the middle ; they are indefinitely striate, 

 when examined sideways they appear to be formed of small granular 

 asperities ; second interstices slightly obtusely elevated at the base ; the 

 yellow setae are very unevenly distributed, with a tendency to form small 

 patches, behind particularly ; posterior declivity without discernible 

 sculpture. 



Scape finely setose ; basal joint of funiculus fully a tliird the length of 

 the scape, hardly twice as long as the nt^xt, third and fourth slightly longer
