1396 COLEOPTERA 



Head, including the mandibles, quite as long as the thorax, with 

 only moderately-marked frontal impressions ; eyes prominent, genye 

 swollen. Thorax one-fifth broader than long, widest near the front, 

 gradually narrowed from about the middle, there is a short, nearly 

 straight, space just before the hind angle, so that there appears to 

 be a sinuosity there, and this causes the posterior angle to appear 

 prominent ; the apex is feebly, the middle of the base more evidently, 

 incurved ; disc with slight transverse linear impressions, dorsal 

 groove well marked, scarcely touching the apex, basal fossae large 

 but not extending to the hind margin. ScuteUuvi feebly striate. 

 Elytra broader than the thorax, their sides a little rounded, shoul- 

 ders dentiform ; the striae are rather deep, quite regular, and finely 

 punctured ; interstices slightly convex, differing but little in width, 

 with feeble transverse impressions which, behind, cause a slightly 

 undulate appearance. 



Belongs to the group with two lateral thoracic setaj. It bears 

 no very close resemblance to any other described species. The 

 last abdominal segment has two setigerous punctures near each 

 side.

Mount Arthur. One individual amongst other Carabidaj col- 

 lected several years ago by Messrs. T. F. Cheeseman and A. T. 

 Urquhart. I left it without a name, in hopes of seeing the male. 



2436. P. scitipennis, "-s- Elongate, subparallel, slightly 

 convex; shining, deep-black, legs pitchy-black, antennae and tarsi 

 piceo-rufous. 



ileac? with narrow, almost sulciform, frontal impressions; eyes 

 large, very prominent and convex, the back part of the head there- 

 fore Seems to be much contracted. Thorax about one-sixth broader 

 than long, widest before the middle, rounded towards the front, 

 gradually narrowed backwards, with a very slight, hardly noticeable, 

 sinuation near the hind angle, this is rectangular aiid just perceptibly 

 projecting ; the apex is truncate, the base medially emarginate, and 

 this latter part is notched with punctiform impressions ; the median 

 furrow is broad and deep but does not reach the front margin, the 

 basal fossoB are deep and elongate, almost sulciform, and are placed 

 midway betw^een the middle and the sides. Scutellum striate at 

 base. Elytra broader than the thorax, with slightly-rounded sides, 

 humeral angles slightly dentiform ; their striae are broad, very deep, 

 and regular, and are distinctly and very regularly punctured ; the 

 interstices are of uniform width and slightly raised, the third bears 

 one puncture near the top of the hind slope, the outermost have 

 many large punctures, and the marginal channel is closely punc- 

 tured to within a short distance of the apex. Legs stout ; posterior 

 femora but little inflated, the tibiae slightly flexuous. 



This is a beautifully-sculptured insect belonging to the group 

 with, two lateral thoracic settp. The last ventral segment has one 

 setigerous puncture on each side of the middle,
