Show 1874.] MR. E. C. REED ON CHILIAN COLEOPTERA. 63 few bristles at the apex of the penultimate joint. Mentum with a pointed tooth in the emargination. Surface of the body impunctate. T R A C H Y S A R U S PALLIPES. (Plate XIII. fig. 6.) Acupalpus pallipes, Germ. An. Univ. Chile, 1855, p. 387. This species, peculiar to the island of Juan Fernandez, was first taken by M . Germain, and described by him as Acupalpus pallipes ; but, as I have shown, it is not an Acupalpus; and even if it were, the specific name pallipes was preoccupied by Dejean for a species from Dalmatia. During m y visit to Juan Fernandez I took a dozen under stones on the beach. TRACHYSARUS ANTARCTICUS, n. sp. Oblongus, fusco-aneus, nitidus; antennis, tibiis, tarsis elytro-rumque margine postico et palpis rufo-piceis, his apice pallidis ; thoraceparvo, quadrato, postice perparum subsinuatim angustato, angulis posticis obtusis sed distinctis, foveis basalibus, latis, punctulatis ; elytris parallelis, postice vix sinuatis, supra acute striatis; interstitiis subplanis, tertio post medium uni-punctato, secundo ad basin dilatato ibique striola brevi. Long. 3 lin. S 2 • The male tarsi are only moderately dilated, the joints broad and short, the fourth bilobed, and all densely hairy on the sides, with the squamulae irregular. The epistome has two foveae on the sides, in each of which is a sharp line curving to the margin of the eye. The antennae are rather long, with the third joint densely pubescent, and some hairs on the second. The palpi have no short hairs. The central tooth of the mentum is short and acute. The scutellar striole is sometimes long, and sometimes reduced to a fovea at the extreme base. All the striae are distinct, the seventh, eighth, and ninth much broadened at the apex. I took half a dozen specimens of this species in Valdivia. B R A D Y C E L L U S IMPRESSIFRONS, Sol. I. c. p. 265 (Acupalpus). I am not sure that this species is not a Tachycellus. The middle tarsi of the male are very slightly dilated, and their fourth joint is broad and subbilobed; but I cannot detect any squamulae on their soles. There is a tooth in the emargination of the mentum ; the thorax has distinct hind angles, and the scutellar striole is absent. From the neighbourhood of Santiago. B R A D Y C E L L U S RUFICOLLIS, Sol. I. c. p. 267 (Acupalpus). Closely allied to B. impressifrons, but with the thorax bright red instead of black. I have seen only females. Central Chile. BRADYCELLUS UNISTRIATUS. Bradycellus unistriatus, Dej. Spec. Gen. v. p. 851 (Acupalpus) ; Sol. I. c. p. 269 (Acupalpus). I have not seen any Chilian specimens of this species exactly agreeing with Dejean's description, but have taken an insect differing only in colour, being of a dark brassy-green hue. It has |
