Eiccarton, found by Mr. "Wakefield ; also from Dunedin a con- 

 siderably larger specimen, whicli presents some slight differences, so 

 that it may possibly belong to a distinct species. 



I have thought it advisable to create a new generic name for this 

 species. Its principal structural characters are : antennje 11-jointed, 

 with a very large basal joint, and a triarticulate club ; maxillary palpi 

 largely developed, terminal joint elongate subsecuriform. Head 

 small, with eyes very prominent ; and with the clypeus separated 

 from the front by a deep suture. Prosternal process very narrow, 

 middle coxse nearly contiguous ; epiplcurte of elytra very narrow, 

 except at the base. Its systematic position at present should be in 

 the Trogositid(S, near Ostoma,in. Herr Eeitter's arrangement. 



Getnoma. ruscA, n. sp. 



Dejpressa, suhopaca, fuscula, antennis pedihusque fusco-tesfaceis, 

 pube albido micante sparsim vestita, elytris obsolete ferrugineo-variegatis, 

 setts tenuibus erectis adspersis ; prothorace minus distincte punctato, 

 valde transversa; elytris punctis magnis et profundis, interstitiis 

 angustis. Long. 4 mm. ; lat. 2 m^n. 



Antennae small and slender, the two basal joints paler than the others. Head 

 much narrower than the thorax, closely and indistinctly punctui'ed. Thorax very 

 strongly transverse, a little narrower than the elytra, very slightly emarginate in 

 front, 80 that the front angles are very indistinct and scarcely at all prominent ; 

 hind angles also very indistinct, its punctuation coarse but very obsolete, and nearly 

 wanting along the middle ; it is of a smoky colour, becoming yellowish at the 

 margins, and bears fine not very distinct hairs. Elytra densely covered with coarse 

 punctures, and bearing a fine white pubescence, which at the margins is rather long ; 

 and also with some upright fine hairs ; they are of a smoky colour, but are very 

 indistinctly variegated with reddish or yellowish spots. Legs smoky-yellow. 



Christchurch, found by Mr. Wakefield. 



Getnoma diluta, n. sp. 



Depressa, subtus fusco-testacea, supra magis testacea ; elytris pube 

 argentea irregulariter vestita, setisque erectis tenuibus minus conspicuis, 

 Jhrtiter pimctatis, interstitiis lat is ; prothorace obsolete punctato. 



Long. 4<^ mm. ; lat. 2\ mm. 



This species is very closely allied to G. fusca, but is paler in 

 colour, and has the punctures of the elytra much less dense, their 

 silvery pubescence is more conspicuous, and the margins are a little 

 more conspicuous. 



Tairua ; I have received one individual from Captain Broun ; a 

 second, destroyed on the journey, was numbered by him 158. 



I have also proposed a new generic name for these two species. 

 The chief characters are : antennae small and slender, 10-jointed, with
