Platypus spinifer n. sp. 



cf. Front and elytra dark brown, the prothorax a lighter 

 reddish-Lrown. Front flat, anterior half sHghtly raised 

 centralJy from the epistoma to the centre of the front, almost 

 smooth but laterally and basally surrounded with coarse large 

 punctures; the posterior portion of the front rugose and 

 punctured, tbe centre of the vertex slightly raised. 



Prothorax sub-quadrate, the sides shghtly rounded and 

 contracted towards the base ; irregularly and coarsely 

 punctured, especially laterally, the base very shghtly sinuate, 

 the central longitudinal groo^■e extending obscurely to the 

 centre, and j)osteriorly continued beyond the basal margin 

 as a strongly grooved, obtuse spine. Elytra with the sulci 

 broad and opaque, the interstices convex and shining as far 

 as the declivity and thence granular to the apex ; the third 

 interstice broader than the rest, especially towards the 

 declivity, and all are furnished with uniseriate short hairs on 

 the declivitous portion ; the transverse apical groove narrow 

 and shining, ending laterally in blunt processes, slightly 

 incurved, with three or four smaller and more pointed 

 s':^]-rations above them on the outer elytral edge. 



Abdo)ii(n having the first four segments convex and opaque, 

 the ilrst being furnished with a large central spine and the 

 second with two equally large lateral ones, all the segments 

 being coarsely punctured. The anterior tibiae on the outer 

 side rugose ])asally, wdth three carinae towards the apex. 



9- Front furnished with a sub-triangular space just above 

 the epistoma, covered with microscopic transverse ridges and 

 margined with a few large punctures, exterior to w^hich 

 again the surface is strongly rugose ; whilst posterior to this 

 space there is a deep depression between the points of 

 insertion of the antennae, the remainder of the frontal 

 surface being very coarsely and longitudinally ridged, with 

 some large but shallow^ punctures on the space between the 

 eyes, the whole of the front being more or less hairy. 



Prothorax oblong, shining, sparsely covered with shallow 

 punctures more especially at the base ; the central basal 

 longitudinal groove extending nearly to the centre with 

 elongate patches on each side, consisting of small, clearly 

 margined, round pores, each patch being enclosed by 

 a sharply-defined groove.
