mesial impression extending from base to apex, its whole surface moderately 

 coarsely and closely punctate. Scutelhim subquadrate, smooth. Elytra 

 subcylindrical, slightly broader than thorax at the base, quite twice its length, 

 apices singly broadly rounded ; they are evidently punctate-striate, inter- 

 stices finely seriate-punctate and rugose. , 



Scape straight, gradually thickened, medially inserted, attaining the 

 middle of the eye ; 2nd joint of funiculus a trifle longer than 3rd, but shorter 

 than 1st, joints 3-5 transverse ; club oblong-oval but not elongate, obso- 

 letely annulate. Legs and tarsi of normal structure. 



This cannot be made to accord with Wollaston's diagnosis of P. sub- 

 sericatum. The rostrum is just a little longer than that of the male 

 P. zealandicum, the scape is rather shorter, and the insect itself is more 

 slender. Its discrimination is comparatively easy, owing to the quite 

 obvious pubescence and longitudinally impressed rostrum and thorax.

Wairiri, Kaikoura. A single male found by Mr. W. L. Wallace. It 

 should be placed in sect. 1, " Revision of New Zealand Cossonidae," p. 156 

 (Trans. N.Z. Inst., vol. 41), but the vestiture renders it somewhat aberrant. 



3334. Pentarthrum tenebrosum sp. nov. 



Subcylindric, narrow, slightly nitid ; rufo-piceous, tarsi and antennae 

 dark red ; pubescence elongate and slender, sparingly distributed, yellow. 



Rostrum subparallel, very slightly contracted near the base, truncate 

 at apex, a third shorter than thorax, distinctly punctured, finely in front, 

 more closely and coarsely near the eyes. Occiput smooth. Thorax quite 

 as long as broad, posterior angles rounded, its sides gradually narrowed 

 towards the well-marked frontal constriction ; disc broadly flattened along 

 the middle, moderately coarsely but less closely punctured than the sides, 

 apex smooth. Scutellum smooth. Elytra not at all broader than thorax, 

 twice its length, cylindrical, apices obtusely rounded ; they are rather 

 closely and distinctly punctate-striate, the 3rd and 4th striae, however, are 

 rather shallow, interstices seriate-punctate and rugose. Legs with flavescent 

 hairs ; 3rd tarsal joint but little dilated, and not perceptibly lobed. 



Scape medially inserted, straight, reaching backwards to front of eye ; 

 2nd joint of funiculus shorter than 1st and not sensibly longer than 3rd, 

 which, like the 5th, is transverse ; club pubescent, oblong-oval, not elongated, 

 obsoletely annulate. 



The rostrum is rather longer than that of the female P. zealandicum 

 and much more distinctly sculptured, the eyes are a trifle more prominent, 

 the legs are more slender, and the body smaller and narrower. The short 

 scape, dark colour, and bright pubescence are distinctive. Though some- 

 what similar to the recently described P. auripilum from Pitt Island, this 

 is discriminated by its medially flattened, more closely and coarsely punctate, 

 and deeply constricted thorax.
