Show 70 MR. M. JACOBY ON THE [Feb. 1, differs from E. malayana, Baly, in having more elytral tubercles and two, not three, very obsolete longitudinal ridges, the one commencing at the shoulder joins the subsutural one, with which it forms an angle near the middle of the disk; the transverse and other shaped tubercles at and below the middle are very acutely raised and form sharp projections. DEMOTINA THORACICA, sp. nov. Greyish fuscous, closely pubescent; the apices of the tibiae fulvous ; thorax strongly rounded at the middle, obscurely marked with brownish bands ; elytra covered with light grey pubescence, a spot at the base and two rows of similar spots below the middle, placed transversely, fuscous. Length \\-2 lines. Head closely punctured, covered with light grey pubescence, which is interrupted at the vertex by two more or less distinct longitudinal brownish bands ; the anterior margin of the clypeus and the labrum fulvous, glabrous. Antennae half the length of the body, slender, the terminal joints slightly thickened, the third and fourth joints equal, all the joints piceous or dark fuscous. Thorax transverse, strongly rounded and widened in the middle, the entire surface covered with whitish-grey pubescence, which assumes the shape of a longitudinal band at the sides; the latter with a round depression. Scutellum greyish pubescent. Elytra finely punctate-striate, clothed with greyish pubescence like the thorax ; at the basal margin two fuscous or dark brown spots are seen, more or less distinct, and bounded at the sides by whitish bands ; below the middle two transverse rows of similar spots are placed ; all the femora are armed with a strong tooth ; the sides of the elytra are furnished with short and stiff bristles. Hadley, in Dikoya. The thorax in the present species is much narrowed in front and at the base, giving more prominence to the middle; the pubescence of the upper surface is generally whitish grey, but sometimes of a more fulvous tint, and the fuscous spots are more or less distinct; in well-marked specimens they are often preceded by whitish spots, caused by the more thick pubescence in those places; in some specimens three oblique rows of obscure spots may be seen at each elytron besides those at the base, which are generally present. DEMOTINA SEMIFASCIATA, sp. nov. (Plate X. fig. 1.) Obscurely fuscous or piceous ; finely pubescent; antennae and legs dark fulvous; scutellum white; elytra closely and distinctly semipunctate-striate, with an obscure darkish transverse band below the middle; a spot at the base and four or five others below the middle, white; femora strongly toothed. Length 2-3 lines. Head clothed with yellowish pubescence at the vertex, which hides the punctuation ; epistome impubescent, distinctly punctured, ful- |
