They were taken at Sandy Point on January 8th, 1879. DYTISCID^E. 5. R H A N T U S DARWINII, Babington, Trans. Ent. Soc. iii. 1841, p. 8. A single female example which I refer with some doubt to this species. It is a trifle more parallel than the type specimen; and the thorax is rather more dull. It was taken at Isthmus Bay. 6. RHANTUS MIXTUS, sp. n. Ater; clypeo capiteque antice piceo-fiavis; ihorace piceo-jiavo, margine antico punctato, basi medio nigra; elytris politis, piceo-nigris, crebre seriatim piceo-jlavo guttatis ; antennis, palpis, pedi-bus prosternoque piceis. Long. 5^ lin. 3. Very close to R. varius, Fabr. (Ent. Syst. i. p. 195), but larger, darker in colour than that species usually is, and a little less regularly elliptical. Head finely coriaceous, with an impressed line within each eye. Thorax shining, a little wrinkled at the sides, with an imperfect impressed median line; the middle portion of the anterior margin is distinctly punctured, and this part is also blackish; the base is narrowly margined with black, the black is more suffused in the middle ; the posterior angles are a trifle greater than a right angle. Elytra very shining, nearly black, with closely placed lines of small yellowish spots as in R. varius, but not so conspicuous ; the margins are yehow; the extreme apex (which is obliquely truncate) is margined with black ; there is a line of rather close distinct punctures not far from the suture; and there is a second very irregular line of similar punctures extending from within the shoulder to near the apex. The whole of the underside is black, except the front part of the prosternum and the sternal process. The apical segment of the abdomen is densely longitudinally strigose, the striae reach the base of the segment in the middle but not at the sides. The legs are pitchy, the posterior tarsi being darker; the intermediate femora and tibiae are closely and rather roughly punctured, more closely and more distinctly than in R. varius. Four male examples, marked " T o m Bay, April 22, 1879." LUCANIDJE. 7. SCLEROSTOMUS FEMORALIS, Guerin, Rev. Zool. 1839, p. 303. A single male example taken at Sandy Point. MELOLONTHID^E. 8.
