COSSONIDAK. 253 



serial punctures und rugose, the 3rd raised and bent outwardly at the 

 extremity; in some lights the striae appear to be crenate-punctate. 



Femora stout, subclavate; tibiae rather short, with strongly de- 

 veloped apical hooks; penultimate tarsal joints a little dilated, excavate 

 above, but not percej^tibly lobed. 



Scape medially inserted, attaining the middle of the eye, slightly 

 flexuous and incrassate towards the extremity; 2nd joint.of the funiculus 

 smaller than the basal, joints 3-5 successively shortened and expanded ; 

 club densely pubescent, oblong-oval, nearly as long as joints 2-5 of the 

 funicle taken together. 



Underside shining, nigro-piceous; metasternum and basal two 

 ventral segments moderately coarsely punctate, the former distinctly 

 longitudinally grooved behind, the latter, together, nearly the length 

 of the metasternum, both slightly impressed in the middle, their suture 

 indistinct. 



This does not accord very well with the tyi>ical members of the genus, 

 but after jn-olonged study 1 see no more suitable place for it at present.

Bell Rock, near Methven. Two individuals obtained from leaf- 

 mould on the 15th September, 1912, by Mr. T. Hall. 



3658. Gaurocryphus mirandus sp. nov. GaurocrypJrus Broun, Trans, 

 N.Z. Inst., vol. 41, p. 185. 



Fusiform, moderately nitid; castaneo-rufous, antennae and tarsi 

 ferruginous; pubescence conspicuous but not dense, bright yellow, 

 slender, very elongate and decumbent on the rostrum and thorax, sub- 

 erect on the elj^tra. 



Rostrum slightly arched, lialf the length of the thorax, a little con- 

 tracted behind the middle; very distinctly, and moderately closely 

 punctate in front, more coarsely, closely, and quite rugosely behind, 

 and as far as the back of the eyes; occiput short, distantly but dis- 

 tinctly punctured. Thorax widest and roun(ied near the base, curvedly 

 narrowed there, gradually towards the front, constricted near the apex, 

 its length a third more than the breadth; it is only very slightly convex, 

 moderately closely and rather coarsely punctured. Scutellum smooth, 

 small but distinct. Elytra very little wider than the base of the thorax, 

 not twice its length, a good deal narrowed behind; they are nearly 

 plane above, moderately coarsely striate-punctate, quite striate behind; 

 interstices with serial punctures and rugose. Legs stout; penultimate 

 tarsal joints slightly expanded, excavate but not lobate. 



Scape inserted just before the middle, stout, gradually incrassate, 

 straight; joints 2-5 of the funicle subtransverse and nearly equal; club 

 oblong-oval, hardly as long as the preceding three joints together. 



The rostrum is relatively longer and nan-ower than that of the male 

 of Pentarthrum zenlandicnm , 903, the thorax is longer but tlie elytra 

 are sliorter, the eyes though smaller are more convex, the scape is 

 shorter; and the rostrum of the female of G. miricomvs, 1302, is only 

 slightly narrower but longer than that of tlie male, and therefore 

 essentially different in structui-e from that of Pentarthrum. These notes 

 will be more useful to students than my comparing this species witli 

 1302, of which I obtained two examples during forty years.

McClennan's Bush, near Methven. I am indebted to Mi-. T. Hall for 

 my specimen, which was found on the 15th March, 1912.
