OF BALANINUS OCCURRING IN BORNEO. 375 



the eye, the lower surface being about on a level with the lower 

 edge of the eye. Rostrum shorter than the body (5 : 7 ), finely 

 and sparsely punctate at the base, without any lateral furrow or 

 carina, the scrobe entirely lateral. Autennce \\iiiQrte({ well behind 

 the middle of the rostrum, the scape reaching the eye ; the 

 funicle with joint 1 slightly longer than 2, and 3 than 4, 4-7 

 almost equal in length ; the club elliptical, joint 1 slightly longer 

 than 2, and 2 than 3. Prothorax very slightly broader than 

 long, the sides subpai'allel near the base, then roundly narrowed 

 to the apex, the apical constriction faint : the apical margin 

 feebly arcuate dorsally, and witli no postocular lobes ; the upper 

 surface with regularly reticulate punctures. Elytra as in 

 B. excisijjes, but more rapidly narrowed behind, so that the 

 shoulders appear more prominent ; the scales on interval 2 are 

 distinctly broader, being 3-4 deep in the broadest part and 2 deep 

 near the apex (5 and 2 respectively in B. e.vcisipes). Legs as in 

 B. excisijyes 5 , except that the internal basal sinuation of the 

 tibiae is distinctly deeper, and the scales on the upper surface of 

 the hind tibiae are rather broader than any others on the legs.

In B. excisipes the central stripe on the pronotum is much 

 broader and composed entirely of transverse scales, whereas in 

 the present species all the scales lie longitudinall}^, except those 

 at the extreme base. 



7. BaLANINUS BILINEATUS, Sp, n. (PI. I. fig. 4.) 



S ? . Colour dull black, the pronotum without pale markings; 

 the elytra with a stripe of broad, pale yellow scales on interval 2 

 from the base to beyond the middle (the scales 4-5 deep at its 

 broadest), an apical patch of similar scales between stria 2 and 

 the margin and extending forwards on intervals 5-7 as far as the 

 termination of the stripe on 2, intervals 8-10 thinly clothed v/ith 

 minute setiform white scales ; the prosternum with a dense ante- 

 coxal patch of broad yellowish scales, the sides with narrower 

 isolated whitish scales ; the meso- and metastei-num Avith broad 

 yellowish scales which are fairly dense throughout except in the 

 middle of the mesosternum ; the abdomen densely clothed with 

 narrower whitish scales. 



Head with the rostrum arising at about ( c? ) or well below ( $ ) 

 the middle of the eye. Rostrum — cT , two-thirds the length of 

 the body, rather irregularly punctate in the basal half, with 

 a veiy narrow smooth central line and a punctate lateral furrow 

 extending for about four-fifths of the scrobe, which passes 

 beneath the base of the rostrum and not beyond the antenna ; 2 ? 

 shorter than the body (7 : 9), the punctures finer, and the lateral 

 furrow shorter. Antennce inserted about ( c? ) or well behind ( $ )
