1438 COLEOPTEEA 



margined, posterior angles obtuse, base subtruncate, its surface with 

 comparatively large, distant punctures. Elytra oblong, apices ob- 

 tusely rounded, their punctuation fine and rather shallow. 



Broader and less convex than Ptenidium lawsoni, and distinguished 

 from it by its paler colour and the dark apical space on the wing- 

 cases. 



Length, J- ; breadth, J line. 



Capleston. One individual, found by Mr. Cavell. 



2495. P. proprium, n.s. Oblong, rather convex, shining, red- 

 dish-chestnut, legs and antennae testaceous ; sparingly clothed with 

 short yellowish hairs. 



Head large, but narrower than the thorax, apparently smooth. 

 Thorax transverse, its sides finely margined and well rounded, 

 slightly sinuously narrowed behind; posterior angles rectangular, 

 not prolonged backwards so as to embrace the shoulders ; base very 

 finely margined and nearly truncate ; its surface impunctate, but 

 with some minute, distant, granular elevations. Scutellum large, 

 triangular, with six rather large punctures ; three of these form a 

 transverse row near the base, there are two across the middle, and 

 one near the apex. Elytra oblong, their sides marginated and a 

 little curved, slightly wider near the middle than they are at the 

 base, the shoulders obtuse, so that the basal angles of the thorax 

 extend a little beyond them, the apices obtusely rounded (singly) 

 towards the suture ; their punctuation is nearly as coarse as that of 

 the scutellum, it becomes more distant behind, and rather less dis- 

 tinct. Pygidium exposed, yellowish. 



Underside shining, testaceous, with pale, slender pubescence. 

 Posterior coxa not laminate, widely distant. The mesosternal pro- 

 cess, between the middle coxae, is rather large and thick. Across 

 the front of the prosternum, at each side of the middle, there are 

 four or five punctures. The mesosternum is coarsely sculptured, 

 granulate apparently. The terminal joints of the maxillary palpi 

 are thick, with an acicular seta at the apex of each. The tibia are 

 straight ; the anterior have some elongate, slender setae, two of which 

 extend below the tarsi for about two-thirds of their length. Eyes 

 coarsely facetted. 



This species may be easily distinguished by the peculiar punctua- 

 tion of the scutellum. 



Length, ; breadth, J line. 



Maketu, Hunua Eange. Two examples, the reversed one much 

 paler than the other, and, most likely, immature. 



2496. P. cavelli, n.s. Subdepressed, suboblong, slightly nitid, 

 fuscous, the legs, antennae, and pygidium testaceous; pubescence 

 elongate, slender, yellowish. 



Head large, including the eyes, as wide as the front of the 

 thorax, so sculptured as to appear (when examined under the micro- 

 scope with a half-inch lens) closely covered with flattened granules. 

 Thorax transverse, its sides rounded, apex truncate, base feebly
