OF BALANINUS OCCURRING IN BORNKO. 371 



shorter and equal to but thinner than 7, 5 and 6 still shorter and 

 equal: joints 3-7 bearing recumbent setiform white scales, their 

 density increasing outwardly ; the club fusiform, clothed with 

 fulvous pubescence, joints 1 and 2 equal and a little longer than 

 broad, 3 distinctly shorter. Prothorax about as long as broad, 

 broadest at the base, the sides scarcely rounded except just before 

 the broad shallow apical constriction ; the base marginate and 

 produced in the middle, the apical margin rounded dorsally and 

 without postocular lobes ; the upper surface smooth and shiny, 

 with numerous small separated punctures and no smooth central 

 line, the sides of the prosternum with larger and closer punctures. 

 ScuteUitm relatively small, longer than broad and with a few- 

 minute pale scales. Elytra elongate cordiform, the shoulders not 

 very prominent, the sides nearly straight, the apices almost 

 jointly rounded, tlie lateral margins deeply sinuate near the base ; 

 the upper surface almost flat, with comparatively narrow and 

 shallow strife, which become much shallower behind, strife 9 

 and 10 practically reaching the base, the suture deeply and 

 symmetrically impressed in the basal half ; the intervals broad 

 and plane, with fairly close and slightly wrinkled punctures. 

 Legs very long and slender, with sparse setiform pale scales ; the 

 hind femora projecting shortly beyond the apex of the elytra and 

 the tooth on them but little larger than that on the mid femora. 

 Sternum with a deep impression along the upper edge of the 

 metepisternum, the projecting margin bearing a fringe of over- 

 hanging scales. Venter with segment 1 distinctly longer than 2 

 behind the coxse, the external angles of 2 scarcely produced. 



Length, 8"4mm. ; breadth, 4 mm. 



Sarawak: 1 $ , Mt. Merinjak, 2200ft., 27. v. li{Q. E.Bryant). 



Difiers from all the known Boruean species owing to its 

 smooth pronotum and the impression on the metepisternum, 



3. Balaninus bispilotus, sp. n. (PI. I. fig. 2.) 



S 2 . Rather dull black, with patches of pure white scales ; 

 the elytra with a transverse white band behind the middle 

 extending from interval 3 to 8 or 9, and an elliptical marginal 

 patch at the apex which does not quite reach the suture ; in the 

 2 only there are also a few white scales near the base of 

 interval 2 ; the front of the prosternum, the mesepimeron, the 

 mesosternal process, the whole side of the metasternum (except 

 the apex of the metepisternum and a small triangular patch at 

 its base) and the entire venter, densely covered with broad white 

 scales ; the coxae, the rest of the mesosternum (except the 

 episterna, which are bare) and the centre of the metasternum 

 with narrower, greyish white scales. Head with the rostrum 

 arising from about ( 2 ) or above ( cT ) the middle of the eyes, the 

 forehead about two-thirds the width of the rostrum at its base 

 and with a shallow fovea. Rostrum — c? , only a little more than
