Tibiis posticis juxta apicem denticido acuto externe munitis. Hab. N.W. Borneo, Kuching. Allied to and somewhat resembling C. mirabilis Gorh. Narrow, elongate, and rather smaller than the unique type of that species ; clothed (including the legs) with very fine hairs. The white markings are (as in other species of this genus) composed of snow-white scales. The pattern is different from that of C. mirabilis in that there are on each elytron but two white lunules unconnected; each pair form an oblong but are scarcely joined at the suture. The apex is truncate, as in C. mirabilis. A single example, apparently a male, collected Oct. 6, 1899. T en eru s su l c ip e n n is (Gahan). Niger; prothorace lateraliter nigro-viridescente, climidio basali elytrorum et plaga sub-semicirculare ad basin pronoti pube r ufo -velut in a obtectis,dimidio apicali elytrorum atro-pubescente. Antennis articulis 3° ad 10""* antice valde dilatatis, articulo 3° quam 4° paullo angustiore; pronoto ad medium basis paullo gibboso ; elytris utrisque quadri-sulcatis, interstitiis sat latis, leviter convexis. Long. 11 ; lat. 2| mm. Hab. Kuching (March 1900). Two examples; in British Museum and Hope Collection, Oxford. This species seems nearest allied to T. cingalensis White and T. parryanus Gorh., but differs from these and from all other known species of the genus in having the third joint of the antennae almost as strongly dilated as the fourth, and the elytra impressed with longitudinal grooves. 4. C o l e o p t e r a : R i iyn ch o p h o r a , Brenthidai, by Dr. A. S e n n a . D iu r u s sh e l f o r d i Senna. (Plate XX. fig. 6, 5 .) Moderately elongate, stoutish, black, provided with whitish scales of differing size sunk in the punctures ; the head and the metarostrum with punctiform close-set scales, the joints of the antennae clothed with long accumbent scales. S . Head slightly longer than broad, with the sides almost straight and a fovea between the eyes, which are prominent; the metarostrum is twice as long as the head and hardly nan-owed before the antennae ; the prorostrum is short, naked, dark reddish brown. The antennae are inserted near the apex of the rostrum : the 3rd joint is longer than the 4th, the 4th a little longer than the 5th, the 7th and 8th subequal; the three apical joints are distinct, slightly thickened and finely pubescent. The protliorax is similarly shaped as in D . furcillatus (Gylh.), but comparatively broader; its upper surface is covered with |
