Broun. — -New Genera and Species of Coleopteva. 387 



about a third broader than the thorax, with rather broad rounded 

 shoulders; they are very distinctly and regularly striate, but the punc- 

 tation of the striae is rather fine; each has a short scutellar stria; there 

 is no subapieal carina; there is a single puncture, placed before the 

 middle, on the 3rd interstices. 



Underside glossy piceous, coxae reddish, the posterior trochanters 

 testaceous. Mesosternum medially convex but not canaliculate, its flanks 

 punctate. Abdomen impunctate, but with some shallow lateral im- 

 pressions. 



'The posterior tarsi are simple, but the 4th joint of the other pairs 

 is distinctly longer than the third, with well-developed rather elongate 

 lobes. In the male the basal four joints are slightly dilated, and of about 

 equal width; the 2nd and 3rd are cordiform, but the sexual disparity 

 is hardly perceptible. 



Var. T. labralis. — Labrum with minutely coriaceous sculpture, but 

 without the least trace of setigerous punctures in front. 



Readily distinguishable by the subcordiform, regularly striated hind- 

 body, with unipunctate interstices, but lacking the usual carinae. There 

 is only one ocular seta, and that of the thorax is situated behind the 

 middle of each side. 



Length, 6^-7 mm. ; breadth, 2§-3 mm. 



Raurimu. I secured five specimens from under logs in January, 

 1910, and Captain H. S. Whitehorn, of the Geological Survey Depart- 

 ment, during March, collected and forwarded a parcel of forest leaves 

 out of which I picked another. These decayed leaves were gathered near 

 the head of the Retaruke River, near the recently surveyed coalfield. 



3171. Tarastethus phyllocharis sp. no v. 



Convex, glossy, piceo-niger; legs ferruginous; palpi, antennae, and 

 tarsi fulvescent ; mandibles and labium pitchy red. 



Head smooth, the frontal impressions rather elongate and deep, so 

 that the broad plica near each eye appears elevated ; labrum incurved 

 in front, with 6 setigerous punctures. Thorax a fourth broader than 

 long, the middle widest, well rounded there, moderately sinuate-angustate 

 behind, posterior angles rectangular; disc smooth and convex, the 

 base slightly depressed, distinctly and rather closely punctate, the fossae 

 about equidistant from the sides and middle but not sharply defined, 

 the discoidal groove somewhat expanded behind. Elytra a fifth longer 

 than broad, evidently broader than the thorax, their sides distinctly 

 margined and more rounded at the base and apex than at the middle, 

 the shoulders, however, are rather wider than the base of the thorax; 

 they are seriate-punctate, the inner series, however, almost form striae, 

 the sculpture becomes very much finer and more irregular behind, and 

 the punctures outside the 4th series usually become obsolete near the 

 base; the interstices are broad and plane, and the apical carinae are 

 well developed. 



Underside shining; mesosternum convex and deeply channelled in 

 the middle and punctate at the sides; metasternum broadly concave 

 medially; abdomen impunctate, but with shallow foveiform impressions 

 at each side, the terminal segment, at the extremity, has a pair of 

 setigerous punctures on each side of the middle, where it is finely trans- 

 versely wrinkled. 



The thorax is rather shorter and less deeply sinuate towards the base 

 than in T. puncti colli* (1799), and the whole sculpture differs, and, more-
