Group Trogositid^. Gen., Man. N.Z. Coleopt., p. 177. 

 Leperina shandi, .sp. nov. 



Elongate-oblong, subdepressed, slightly nitid ; fusco-piceous, elytra 

 sometimes rufescent ; legs, antennae, and palpi piceo-rufous ; labrum and 

 sides of thorax reddish ; squaraosity yellowish, depressed, and chiefly 

 confined to the sides of the thorax, thicker and suberect on the elytra, which 

 also bear numerous distinct erect sette, their margins with slender, outstand- 

 ing but short and rather indistinct setae. 



Head coarsely and irregularly punctured, and longitudinally rugose 

 towards the front, it is almost or quite bald ; the lateral protuberances 

 in front of and below the antennae well developed. Thorax 1^ lines long 

 in the middle by 2|- broad, widest near the middle, slightly curve dly nar- 

 rowed towards the prominent anterior angles, rather strongly sinuate- 

 angustate behind, posterior angles rectangular, the lateral margins thick 

 and reflexed, apex fringed with yellow hairs ; the punctation very close 

 and coarse, but becoming more distant towards the middle, and finer near 

 the base and apex ; its sides have small outstanding setae. Scutellum trans- 

 verse, rounded behind, and finely punctate. Elytra wider than thorax at the 

 base, subparallel ; each with 7 linear interrupted discoidal costae, the sutural 

 entire behind ; interstices finely punctured ; the sides are not costate but 

 have three series of punctures or granules ; there are very few dark scales. 



Antennae very scantily pubescent, basal joint large and gradually thick- 

 ened, 2nd transverse, 3-8 as long as they are broad ; club large, its basal 

 2 joints transverse and evidently dilated inwardly, the last longer and 

 rotundate. Legs and tarsi with fine yellow hairs. 



Mandibles bifid at apex. Labrum emarginate in front, large, finely 

 pubescent. 



Larger than L. hrouni, which measures 4 x If lines. The thorax is more 

 transverse, more sinuate behind the middle, with thicker reflexed lateral 

 margins, but it is entirely without the slender yet distinct yellow hairs 

 of that species ; its sculpture also is different. The elytral costse are less 

 numerously interrupted. 



Length, 5^-5| lines ; breadth, 2-2|^ lines. 



Te Whakuru, Chatham Islands. 



Discovered by Miss S. D. Shand, in whose honour it has been named. 



Ohs. — Var. a : Nearly glabrous ; mandibles not bifid, the inner ex- 

 tremity of each broad and obtusely truncate ; unique as yet, may prove 

 to be a distinct species ; 5| x 2 lines. Var. b : Hind angles of thorax more 

 prominent ; 4| x If lines. 



Group LucANiD^. 

 Lissotes dispar, sp. nov. 



Oblong, moderately transversely convex, nitid ; fusco-niger, legs piceo- 

 rufous ; the lateral and basal margins of the thorax thinly, the sides and 

 apical portion of the elytra more thickly, clothed with short fulvescent 

 setae ; the two hind pairs of tibiae fringed with slender outstanding setae. 



Mandibles large, strongly curvate, the right one reflexed at the extremity 

 so as to clear the left ; on each, near the base, there is a short inner angular 

 projection ; just in front of these, and a little lower down, there is a much 

 larger one which touches its fellow during repose ; above, near the inner 

 margin of each mandible, from the middle backwards, there is an elongate 

 obtuse elevation.
