RHYPAROSOMIDAE. 639 



Scape slender and flexuous but subclavate towards the extremity, 

 inserted quite before the middle and reaching the centre of the eye ; basal 

 joint of funiculus rather thicker but not longer than the next, joints 3-6 

 short and indistinctly separated, seventh larger, subquadrate ; club sub- 

 pyriform, considerably narrowed towards the base, obsoletely articulated. 



Underside dull dark fuscous, with a few fine setae, metasternum coarsely 

 punctate ; abdomen almost smooth, basal segment slightly raised and 

 truncate between the coxae and with some coarse short rugae near its base, 

 second evidently larger, its frontal suture distinct and obtusely angulate 

 at the middle, fifth nearly double the length of third and fourth together, 

 transversely depressed near the broadly rounded apex. 



Fern. — Thorax not broader than long, rostrum equalling it in length, 

 longer and more parallel than that of the male. 



There can be no doubt that this is distinct from Sharp's D. mundulus 

 (2133), the thorax not being longer than broad, the foremost elytral fascia 

 is placed behind the middle, and, moreover, the thorax and elytra of 2133 

 seem to be impunctate. 



cJ. Length (rostrum inclusive), 4-4| mm. ; breadth, quite 1J mm. 



Mount St. Arnaud, Nelson ; elevation, 5,000 ft. Two males and a 

 female, found amongst leaf-mould on the 15th June, 1916, and two or three 

 others near Lake Rotoiti. 



4217. Dermotrichus curvirostris sp. no v. 



Subovate, moderately convex, opaque ; fuscous, the rostrum, antennae, 

 and tarsi fusco-rufous, middle of femora fulvescent ; irregularly clothed 

 with subdepressed, short, flavescent setae, which on the elytra form longi- 

 tudinally disposed crests. 



Rostrum rather longer than thorax, strongly arched, almost bare and 

 finely punctate in front, indistinctly tricarinate just behind the antennae 

 and with a nodule between these and the eyes, this in fresh unabraded 

 individuals probably forms a crest. Head short ; eyes small and sub- 

 rotundate. Thorax nearly a third longer than broad, subovate, more 

 gradually narrowed behind than in front ; a little uneven, the basal de- 

 pression not deep, its punctation coarse, shallow, and irregular, with uneven, 

 indistinctly granular intervals ; it is bicristate in front, tricristate across 

 the middle, none of the tufts are very conspicuous. Elytra subovate, nearly 

 2| times the length of thorax, very slightly broader than it is at the base, 

 almost double that width near the hind thighs, considerably narrowed, 

 subvertical, and quite striate behind ; dorsum indefinitely punctate, but 

 with series of small granules, scutellar depression with a ridge of concen- 

 trated setae at each side, and another just behind but outside each of these, 

 across the top of the posterior declivity there are seven crests, the outer 

 ones the largest, there is another small one nearly in line with these on the 

 outside of each elytron, and another just below and as large as the outer- 

 most of the transverse series, besides several small ones towards the 

 extremity. 



Legs elongate, the middle and hind tibiae very distinctly mucronate. 



Scape medially inserted, flexuous, subclavate at the extremity ; basal 

 joint of funiculus hardly as long as the second, the others gradually dilated 

 but very indefinite, so that there may be only five or six instead of seven 

 joints ; club ovate, narrow at its base. 



Underside fuscous, with short yellowish setae, fifth segment reddish ; 

 second segment rather longer than the basal, its frontal suture obtusely
