HETERONYX. 



H. grandis, sp. nov. Robustus, elongato-ovatus ; postice mani- 

 feste dilatatus ; minus nitidus ; piceo-ferrugineus, antennis 

 pedibusque paullo dilutioribus ; pilis cinereis subtilibus sat 

 elomgatis sat crebre vestitus ; capite (clypeo incluso) sat 

 grosse ruguloso ; prothorace aspere subtiliter confertim, 

 elytris sat crebre minus subtiliter, pygidio fere ut elytra sed 

 magis leviter, punctulatis ; clypeo antice late leviter rotun- 

 dato, sutura clypeali bene determinata, angulata , pronoto 

 quam longiori ut 5 ad 3 latiori, lateribus leviter arcuatis, 

 basi modice bisinuata, angulis anticis acutis sat productis 

 posticis obtusis ; elytris obsoletissime infcerrupte substriatis ; 

 tibiis anticis extus obtuse tridentatis ; labro longe sub 

 clypeum sito ; antennis 9-artieulatis ; coxis posticis ad latera 

 quam metasternum parum brevioribus, quam segmentum 

 ventrale 2 um multo longioribus ; tarsis posticis minus elonga- 

 tis, articulo 2° quam l us manifeste longiori ; unguiculis 

 appendiculatis, parte apicali quam basalis parum breviori. 

 Long., 8 1.; lat., 4 1. 



This remarkably fine Reteronyx is near piceus, Blanch. In my 

 tabulation of the species of that group (P.L.S., N.S.W., 1892, pp. 

 488-9) it must be placed next after alpicola, Blackb., as follows :- — 



HHHH. Sculpture of pronotum very much finer and 



closer than of head and elytra ... ... grandis, Blackb. 



The elytra of this species are not truly striate, but their 

 surface is slightly (scarcely visibly) uneven owing to the presence 

 of faint longitudinal wide elevations, the margins of which, from 

 a certain point of view, give the elytra a scarcely noticeable quasi- 

 striate appearance.
