OF BALANINUS OCCURRING IN BORNEO. 379 



band on the elytra before the middle extending from stria 2 to 

 the margin and including the whole shoulder and the base from 

 stria 4 to the mai-gin, and a complete subapical transverse band 

 abovit I mm. wide; on the lower surface the scales are rather 

 wider, except on the sides of the presternum, the middle of the 

 metasternum, and on the whole of the last three ventral seg- 

 ments ; on the mesepimeron and at the sides of the first two 

 ventral segments the scales are larger and closer together, and on 

 the front part of the presternum they are almost round and 

 separated. 



Head with the rostrum arising above the middle of the eye (in 

 side view), its upper edge being on a level with ( 5 ) or above ^6^ 

 the top of the eye. Rostrwm — S , shorter than the body (10 : 13), 

 rather more distinctly punctote than usual iia the apical half 

 (especially at the sides), in the basal half with a smooth central 

 line, and two rows of punctures on each side of it, below these a 

 lateral furrow as long as the scrobe and containing a single 

 regular row of punctures, its lower edge being distinctly carinate, 

 the scrobe passing beneath the rostrum at the base and not 

 extending in front of the antennae ; $ , also shorter than the 

 body (10 : 12) and rather more slender than that of the c? , 

 the punctures finer (except close to the base) and the lateral 

 furrow slightly shorter. Antennce inserted slightly behind the 

 middle of the rostrum in both sexes, the joints of the funicle 

 with pale recumbent setse, the scape not nearly reaching the eye ; 

 joints 1 and 2 of the funicle equal, 3 longer than 4, 4-5 subequal, 

 7 equal to 3 ; the club with yellowish-grey pubescence, joint 1 

 longer than 2, and 2 than 3. Proihorax broader than long 

 (5:4), the sides almost parallel for a short distance from the 

 base, then strongly rounded, the apical constriction well mai-ked ; 

 the apical margin truncate dorsally and with feeble ocular lobes ; 

 the upper surface with regularly reticulate punctures and no 

 distinct; central line. Scutellimn siibquadrate, covered with dense 

 white scales, except a narrow strip on each side. Elytra slightly 

 longer than broad (8: 7), the apices almost jointly rounded, the 

 lateral margins deeply sinxiate; the basal sutural impression rather 

 shallow and asymmetrical, interval 1 of the right elytron being 

 lower than that of the left, the apical third of the suture with 

 erect black spine-like bristles, the striae 9 and 10 not reaching 

 the base. Legs elongate, the hind femora distinctly exceeding 

 the elytra ; the femoral teeth long and sharp, especially that on 

 the hind pair ; the second joint of the hind tarsi longer than 

 broad. Venter with segment 1 longer than 2 behind tlie coxee ; 

 segment 5 of S not impressed and with a stout erect seta on each 

 side at the hind margin.
