Ne7u Zealand Coleoptera. 79 



slender, elongate, erect seta. Under surface and legs 

 nearly black ; tarsi obscure reddish. 



Greymouth ; No. 191, Helms. 



This species is very readily distinguished from the 

 others of the genus by its more elongate parallel form, 

 and the very different elytral sculpture. It no doubt 

 varies in colour to a considerable extent. 



Tarphiomimus wollastoni, n. s. 



Oblongus, superne valde insequalis, squamulis sub- 

 variegatis dense vestitus ; prothorace basi gracili, lateri- 

 bus anterius explanatis, in lobis tribus divisis ; pedibus 

 sat gracilibus. Long. 4 mm. 



This species is very similar to T. indentatus, Woll., 

 but is perfectly distinct therefrom by some important 

 minor points. The thorax has the sides divided in front 

 into three lobes, the posterior fourth lobe seen in T. in- 

 dentatus being here absent, and thus the basal portion of 

 the prothorax appears more elongate and slender. The 

 elytra are even more uneven than in T. indentatus, but 

 their disc is flatter, owing to the fact that the irregular 

 oblique elevation extending from about the middle of the 

 suture directly towards the shoulder in T. indentatus is 

 absent in T. wollastoni. The legs are considerably more 

 slender in T. wollastoni. 



Greymouth ; No. 61, Helms. 



Chorasus, n. g. [Colydiidarum). 



Corpus subangustum, hand convexum, nudum. An- 

 tennse breviusculse, 10-artieulatffi, articulo primo condito, 

 clava abrupte biarticulata. Caput exsertum, oculi 

 minuti, canalicula suboculari maxima. Prothorax sub- 

 tus ad angulos anteriores maxime impresso. Prosternum 

 magnum ; coxae minutse, giobosse, sat distantes. Meta- 

 sternum parum elongatum ; coxae intermedise sat dis- 

 tantes, posticse paulo magis distantes. Abdomen ex 

 segmentis quinque subaequalibus compositum, suturis 

 profundis. Pedes sat graciles, mutici ; tarsi 4-articulati, 

 hand elongati, articulo basali quam 2o paulo longiore, 

 2o et 3o brevibus, 4o quam ceteris paulo longiore. 



The affinities of this little insect with the anomalous 

 European Langelandia are undoubted ; the antennae and
