| Below black; thorax testaceous, bimaculate; elytra finely pubescent, dark greenish black, the suture and lateral margin narrowly testaceous. — Length 5 lines. Head closely punctured at the vertex, without any transverse groove, the frontal tubercles very indistinct; lower part of face testaceous; antennae black, short, robust, fourth joint scarcely longer than the third, the following four joints shorter, broader and somewhat flattened, three terminal ones much narrower and only half the size; thorax nearly 3 times as broad as long, narrowed towards the apex, the sides scarcely rounded, posterior angles slightly oblique, surface very finely and rather closely punctured at the sides, the latter with a deep oblique depression, which is surrounded by a large... |

| Black; head and thorax impunctate; elytra very finely punctured, flavous, a sutural triangular patch from the middle to the apices, as well as a small spot at the apex of each elytron, black. — Length 2 1/2 lines. Head entirely impunctate, the frontal tubercles strongly raised, the carina short but distinct; the lower edge of the clypeus obscure testaceous; labrum and palpi black; antennae half the length of the body, black, the apices of the three lower joints more or less stained with fulvous, the second joint very short, the third and following ones of nearly equal length. Thorax more than twice as broad as long, the sides rounded, narrowly margined, the anterior angles obliquely rounded, the posterior ones acute, the surface entirely impunctate,... |

| Body elongate; eyes round, entire; penultimate joint of palpi thickened; antennae slender, filiform, second joint very short, fourth joint longer than the third; thorax squareshaped, disk transversely depressed at the posterior half; scutellum subpentagonal; elytra elongate, very finely and semiregularly punctured, with some obsolete longitudinal costae; their epipleurae very narrow, extending to the apex; legs rather robust, tibiae unarmed; the first posterior tarsal joint as long as the two following united; claws deeply bifid; prosternum invisible between the thighs; anterior coxal cavities open. In its general shape and squareshaped thorax, the species upon which I am obliged to found the present genus, resembles Phyllobrotica to which it is without... |

| The Sumatran specimens before me, belong with one exception to the var. a. of Lacordaire, in which the underside and the antennae are entirely fulvous; in these specimens, not only the anterior legs, as Lacordaire’s description says, but all are of the same colour. The species seems to vary greatly in this respect, the underside, legs and antennae being either fulvous or black. I may further add to the author’s description that there is a more or less distinct trace of another transverse thoracic depression anteriorly in all the specimens which have come under my observation and which is frequently the case in other species from the eastern parts of the world. |

| A specimen from Sumbawa (v. Lansberge) which I have before me, agrees with the type of the above named species described from Flores. Another specimen from Java in my collection varies in the flavous abdomen spotted with black at the sides, in having the thorax two-spotted, and in the posterior oblong patch at the elytra which extends upwards to the middle. This species ought to be placed in Sphenoraia according to the present definition of the genus (Baly, Cistula 1879), as it possesses all the structural characters and is devoid of the basal elytral depressions as seen in Haplosonyx. |

| Fulvous. Tliorax and elytra finely punctured, the latter black. — Length 7 lines. Head impunctate. Apex of jaws black. Antennae half the length of the body, obscure fuscous above, fulvous below, the apex of the terminal joint black; third joint twice the length of the second; the fourth longer than the 3 preceeding joints together. Thorax transverse, narrow, sides straight at the base, slightly rounded from the middle to the apex, angles acute and thickened, surface with a deep transverse depression at each side and a smaller fovea near the basal margin, very finely and rather remotely punctured. Scutellum fulvous. Elytra deeply transversely depressed before the middle, very finely and irregularly punctured, the punctuation distributed evenly throughout... |
