KLMOLPIDAE. 259 



Antennae equalling the head and thorax in length; their basal joint 

 stoutest, straiglit along the outer side, the inner arched; 2nd cylindric, 

 slender, shorter than the 3rd, which, as well as the 4th, is twice as long 

 as broad; joints 5-7 rather shorter, 8th and 9th slightly shorter and 

 broader, and .somewhat oviform; 10th suboblong; lltli elongate-oval, 

 almost as long as the 9th and lOtli combined. 



Tibiae moderately stout, slender near the base, curved externally, 

 slightly impressed at the outer extremity. Tarsi tliick, of normal 

 structure. 



Underside shining, piceo-niger, bearing short, depressed, greyish 

 setae. Abdomen finely and irregularly punctate; its basal segment as 

 long as the following three conjointly; 5th nearly double the length of 

 its predecessor, subtruncate at apex, so that there appears to be a short, 

 ai)ically rounded, supplementary segment. 



From all the species of about equal bulk this is distinguishable by 

 the tlioiacic impressions and apparently smootli elytra. 



Length, 3i nun. ; breadth, 2 mm. 



INIcClennan's Bush, near Methven. Mr, T. Hall, on the 25th March, 

 1912, sent me a specimen which he found amongst leaf-mould. It is the 

 first of this genus tliat has been secured in the South Island.

 Coleopt., p. 1308. 



Convex, subrotundate, glabrous, nitid; aei.eu-nigei', legs and palpi 

 dark rufous, antennae and tarsi chestnut-red. 



Head rather narrower than front of thorax, slightly impressed or 

 flattened and finely rugosely punctate on the middle, its sides smooth. 

 Thorax more than twice as broad as it is long, gently curvedly narrowed 

 anteriorly, the apex widely incurved and nearly as distinctly margined 

 as the sides, the base slightly rounded; its punctation fine, distant, and 

 irregular. Scutellum moderately large, triangular, smooth. Elytra, 

 at the base, just a trifle broader than the thorax, thrice is length; they 

 are only moderately, but not at all regularly seriate-punctate. 



Antennae slightly and gradually thickened, longer than the head 

 and thorax, finely pubescent from the 4th joint onwards; basal joint 

 stoutest, 2nd rather shorter than 3rd yet twice as long as broad, joints 

 3-10 distinctly longer than broad, the terminal rather more elongate 

 than the penultimate. 



Legs stout, only the tips of the femora visible from above; inter- 

 mediate and posterior tibiae moderately slender near the base, somewhat 

 twisted and bent at the middle, considerably dilated Ixdow that point; 

 the anterior not. tAvisted, much less incrassate, grooved at the outer 

 extremity, and bearing yellow pubescence. 



Underside inmiaculate, bronzed black, with numerous fine grey setae, 

 sparingly and finely punctured. 



This species is chiefly remarkable for the tibial structure. It should 

 l)e placed near C pullatus, 2299, which, however, is smaller, more dis- 

 tinctly and closely punctured, and with ordinary tibiae. The species 

 numbered 2297 and 2298 must be very different, judging by their 

 descriptions, but I have not seen eithei- of them. 



Length, 5 mm.; breadth, 3imm. 



Mount Hutt, near Methven. One discovered bv Mr. T. Hall, at an 

 elevation of 3,500 ft., on the 30tli March, 1912. The large basal joints 

 of the tarsi show that it is a male.
