On new Genera and Species of Tenebrionidse. 277 afterwards approaching each other, and at last slightly diver-gent. ? . Posterior lobe of the prothorax deeply divided by an oval excision ; rhinarium and upper lip blackish ; inner border of the eyes and the cheeks yellowish. (The last three segments of the abdomen are missing.) This species is allied to T. Dictynna, but very distinct by the two pale spots of the front of the thorax being very much smaller, the lateral bands more dilated, and the pterostigma longer. The $ is remarkable for the oval excision which di-vides the posterior lobe of the prothorax. The appendices of the <J are formed like those of T. cyanops ; only the superior are rather more excavated internally, and the inferior rather less contiguous before the apex. Until the present time the genus Trichocnemis was known only from South Asia and the Malayan archipelago. 8. Agrion senegalense, Rambur. Two males similar to those of the African continent and islands. 9. Br achybasis glabra, Burm. (Agrion). Agrion ferrugineuni, Rambur. Two males, similar to those of the African continent, Mada-gascar, and Mauritius. Liege, 9th Feb., 1869. XXXVII. — Descriptions of new Genera and Species of Tene-brionida? from Australia and Tasmania. By Fkancis P. PASCOE, F.L.S. &c. [Continued from p. 153.] [Plate XII.] The three following appear to be degraded Tasmanian forms of Cestrinus, Er.*, and are closely allied ; they are narrower and more feebly constructed, and the prothorax wants the ex-panded margin. Opatrum piceitarse, Hope, belongs to this genus ; with this species his Isopteron opatroides exactly agrees, only the latter has clear ferruginous antenna?. The same author's Platynotus insularis is, I believe, another mem-ber of the genus. The descriptions of these insects and some others, in the ' Transactions of the Entomological Society ' (ser. 1. vol. iv.), were very concise; and they were left un-* Wiegm. Arch. 1842, i. p. 172.
