species of Keic-Zealand Coleoptera. 393 



distinctly truncate in front ; labrum shining, very prominent, 

 strongly rounded and finely setose at apex ; mandibles red, 

 minutely bifid at the extremity and with an inner central 

 tooth. Thorax rather broader than long; from the apex for 

 two-thirds of the whole length the side is formed of one 

 thick, granule-studded curve bearing fine, short, curled yellow 

 setae, the basal space therefore, though straight, appears 

 abruptly contracted and on a lower plane, the side, within 

 the curved lobe, is broadly channelled ; a pair of ridges 

 start from tlie apex and are curved outwards at the middle ; 

 the surface is a little uneven, with granular sculpture. 

 Elytra oblong, as wide as thorax, sides and apex nearly 

 vertical, lateral margins indistinct and not perceptibly 

 serrate ; disk nearly fiat, studded with series of granules ; 

 third interstices smooth, a little elevated, nodiform and setose 

 on top of the declivity, at the base there are two longitudinal, 

 but not very elongate elevations, the humeral angles are 

 obtusely rectangular. Tib'ice straight, fringed with short 

 yellow setae, but not serrate. 



Antennce rather short and exhibiting malformation ; second 

 joint stout, aboiit as long and thick as the exposed portion 

 of first ; the third longer than broad, longer than fourth ; 

 fifth distinctly longer than third ; joints 6-8 short ; in this 

 case the fifth is probably made up of two joints. The other 

 antenna has two distinct basal joints like those first described, 

 then follows one long joint composed, I believe, of three 

 coalesced articulations, the succeeding three are bead-like ; 

 ninth indistinct. Club stout, pubescent, biarticulate. 



As there is only one specimen extant it is not easy to 

 decide, by superficial examination alone, whether it is con- 

 generic with the typical species. The antennge, indeed, in 

 perfect examples may be 10-articulate, in which case this 

 species would become the type of a new genus near Chorasus. 

 It may be identified by the peculiarly curved, lobe-like sides 

 of the thorax.

luvercargill (^Mr. A. Philpott). 



Pycnomerus sukri, sp. n. 



Ehngate, subparallel, slightly nitid, nude, f ulvescent ; 

 antennae and tarsi red. 



Antenna with yellow pubescence, second joint longer than 

 the exposed portion of the first, but, nevertheless, very short 

 and transverse ; third slightly longer, narrowed at its base ; 

 joints 4—9 transverse ; tenth nearly twice as broad as the 

 preceding one ; terminal joint rather longer and narrower.
