HOPLONYX LUSCUS, 11. Sp. 



Black, shining, glabrous, palpi, antennal joints and tarsi piceous, 

 and anterior part of the head considerably narrower than the strongly 

 bulging eyes which are separated right to the vertex by a linear, 

 extremely narrow keel, the supra-antennal ridges are very sharp, and 

 the punctures are moderately deep and moderately closely set ; 

 prothorax sub-parallel, but slightly rounded and attenuated laterally 

 in the anterior part, and covered with equi-distant, moderately deep 

 punctures separated from each other by a space equal to their own 

 diameter, scutellum sub-ogival ; elytra broader than the prothorax 

 and with the shoulders somewhat rounded, parallel, moderately 

 attenuate towards the apex, moderately convex 011 the upper side, 

 faintly striate, with the striae filled with deep, round punctures 

 divided from each other by a smooth space about equal to two-thirds 

 of their diameter, the interspaces are plane, and have each a double 

 row of fine punctures ; all the punctures either in the striae or in the 

 intervals are a little deeper in the anterior than in the posterior part ; 

 abdomen strigose ; pectus punctulate ; legs finely punctate ; tooth of 

 anterior femora strong and sharp. 



Allied to 0. longitarsis, Fahr., but the prothorax is not so deeply 

 and closely punctured, and the punctures are round ; the elytra are 

 not so deeply striate, especially the three juxta-sutural ones, and the 

 intervals are plainer in the basal part. 



Length 11-14 mm. ; width 5-6 mm.

GEN. ACASTUS, Pering. 



ACASTUS SEBAKUENSIS, n. Sp. 



Chestnut-brown, somewhat shining, almost glabrous on the upper 

 side except the epistome, very briefly pubescent on the under side 

 and legs ; prothorax slightly rounded laterally, sinuate above the 

 basal angle, covered with contiguous cicatricose foveate punctures, 

 the disk is plainly impressed longitudinally on each side with the 

 median part standing in relief, and the impressions are hedged 

 outwardly by a longitudinal, rounded, wall-like elevation plainly 

 tuberculate in the middle, the base is strongly bi-sinuate ; elytra 

 parallel, very sharply costate, with the intervals filled by a series 

 of deep punctures separated by an interval equal to their own 

 diameter, and not impinging on the sides of the costae ; abdominal 

 segments punctulate, metasternum and legs somewhat roughly 

 punctured.
