Show 90 MR. M. JACOBY ON THE [Feb. 1, groove, which extends to the inner margin of the eyes. Antennae nearly as long as the body ; the 4 or 5 lower joints obscure fulvous, the five following ones black, the apical joint reddish fulvous; the third and fourth joints equal. Thorax transversely subquadrate, the sides straight, the posterior margin slightly lobed, the anterior angles obliquely truncate and slightly thickened; surface with a deep, strongly sinuate, transverse groove near the base, extending nearly to the posterior angles, the latter produced into a tooth ; the disk impunctate, the groove itself with some punctures ; scutellum fulvous. Elytra with a well-marked basilar depression, the shoulders prominent, the disk strongly punctate-striate, the punctuation diminishing towards the apices, the interstices slightly costate near the sides. Prosternum rather broad ; the anterior coxal cavities open. 31. apicicornis resembles greatly several species from the Malayan regions which served me for the establishment of the present genus ; their general appearance is that of a small species of Crepidodera, from which the open coxal cavities and the strongly sinuate thoracic groove separates Manobia. In M. apicicornis, which seems to be a very variable species, the apices of the elytra are pale fulvous, while the last joint of the antennse is of a more reddish colour; this is constant in all the specimens before me, and separates the species from its allies. CREPIDODERA HIRTIPENNIS, sp. nov. Oblong-ovate ; black ; antennse and tarsi flavous ; thorax rugose-punctate ; elytra strongly punctate-striate, the interstices costate, and clothed with long white pubescence. Length \ line. Head not visibly punctured, with some single long white hairs. Antennse a little shorter than the body, the third and the two following joints equal, slightly shorter than the second but not so stout; terminal joints slightly thickened, the apical one fuscous, the rest flavous. Thorax rather more than twice as broad as long, the sides nearly straight, the disk strongly rugose-punctate, transversely grooved near the base. Elytra with regular rows of deep punctures, the interstices strongly costate, and furnished with long white single hairs. Legs black, tarsi flavous. Of this small and interesting little species there is only a single example before me. As the specimen is carded, I am not able to say anything about the state of the cavities or other characters of the underside, and have placed it at present in Crepidodera on account of the thoracic groove and punctate-striate elytra. The following species, of which also only a single specimen was obtained, is still smaller. Both agree in the almost equally stout femora of all the legs, which leaves it doubtful whether these species would not equally well find their place amongst the GalerucinEe. CREPIDODERA MINUTA, sp. nov. Entirely pale fulvous; head impunctate; thorax very closely |
