golden-yellow ; the lateral margins with five long setae. Abdomen rather 

 closely and finely punctured, except posteriorly, the 7th segment being im- 

 puuctate, rather closely covered with golden-yellow pubescence ; the sides and 

 apex furnished with long black setae, the dorsum also with a few erect 

 black setae. 



Hah. Borneo, Quop, W. Sai-awak {G. E. Bryant). 



OJoplirinus octolineatus, n. sp. 



Black, shining, convex, robust ; each elytron with eight rows of large 

 regular punctures; first four joints of the antennae, mouth-parts, and legs 

 reddish-testaceous. Length 6-2 mm. Head black, the front reddish- 

 testaceous ; eyes large and prominent ; puncturation wanting, ground- 

 sculptiu'e exceedingly fine and strigose. Antennae long, slender, the 1st, 3rd, 

 and 4th joints of about equal length, the 2ud shorter, the 5th to the 10th, 

 elongate, very gradually diminishing in length, the 11th elongate, as long as 

 the 10th. Thorax twice as broad as long, widest at the base, the sides strongly 

 convergent and gently arcuate to the rounded anterior angles ; anterior border 

 emarginate, posterior border feebly bisinuate, the posterior angles obtusely 

 rounded ; impimctate and glabrous, with the ground-sculpture similar to that 

 of the head. Scutellum semicircular, impunctate. Elytra broader than and 

 half as long again as the thorax, transrei*se, narrowed posteriorly, each marked 

 with eight rows of regular punctures (which do not quite reach the apex), five 

 between the suture and the humeral callus, and three between this and the 

 margin, one row being actually in the marginal groove itself; the three inner 

 rows consist of finer punctures than those forming the outer ones ; apart from 

 these there are three or four small punctures at the postero-extemal angles, 

 otherwise the surface is impunctate and with similar ground-sculpture to that 

 of the head and thorax. Abdomen narrowed behind, puncturation fine, super- 

 ficial, and sparing, pubescence scanty. 



cJ . Eighth dorsal segment divided by five excisions into six pointed, 

 triangular processes, of which the central pair extend furthest back, and the 

 outermost are the least produced ; the central excision is narrower and more 

 pointed, not extending so far forwards as the lateral ones. Sixth rentral seg- 

 ment with a broad, deep, triangular excision in the posterior margin, lateral 

 margin with a short dentiform process on each side. Fifth ventral segment 

 with a rather broad emargination (which is finely crenulate) of the posterior 

 margin, in front of which is a shining quadrilateral impression ej^tending 

 nearly to the anterior border, studded with shining granules. Fourth ventral 

 segment with a narrower, less deep emargination, the edge of which is finely 

 crenulate.

Leucocraspediim nigromacidatum, n. sp. 



Reddish testaceous, the elytra blackish, the base broadly, the suture, apex, 

 t;nd sides narrowly, reddish-testaceous ; the second dorsal segment with an
