Two exactly similar specimens were sent by Mr. Marshall. CRYPTOCEPHALUS FLAVO-ORNATUS, sp. n. Flavous, the apical joints of the antennae black, above fulvous ; the thorax impunctate, the lateral margins and a central longitudinal stripe flavous ; elytra rather closely punctate-striate, the interstices minutely punctured. Length 4-4^ millim. Of parallel, subcylindrical shape, the head with a distinct central longitudinal sulcus, sparingly punctured, fulvous, the space near the eyes flavous ; the latter reniform, broadly emarginate at the middle ; antennae comparatively short and robust, black, the lower five joints flavous, second and third joints short, equal, terminal joints robust and strongly widened ; thorax twice as broad as long, very convex, the sides nearly straight, the surface entirely impunctate, with a distinct oblique depression at the base on each side in front of the scutellum ; the disc fulvous, interrupted by a narrow central flavous stripe from the base to the apex, the sides likewise narrowly, aud the posterior angles more broadly flavous, extreme basal margin black ; scutellum flavous, its apex truncate; elytra parallel, closely and rather strongly punctate-striate, the punctures somewhat closely placed and smaller towards the apex, the interstices finely punctured ; the epipleurae at the base, the underside, and the legs flavous ; the pygidium rugosely punctured. Hab. Salisbury, Mashonaland (67. Marshall). This species was obtained, according to M r . Marshall, on Mosasa ; it will not be difficult to recognize it on account of its uniform coloration of the elytra and the flavous markings of the thorax. I am not acquainted with any other African representative of the genus with which it may be compared in this respect; in some specimens the extreme sutural and lateral margins are stained with flavous. CRYPTOCEPHALUS V-NIGRUM, sp. n. Black; the basal joints of the antennae, the tibiae more or less, and the thorax at the sides and middle, flavous ; thorax extremely finely punctured ; elytra strongly punctate-striate, flavous, a spot on the shoulder, another near the scutellum, and two subquadrate, connected spots in shape of an inverted V below the middle, black. Length 5 millim. Head entirely black, strongly punctured and sparingly pubescent, slightly depressed between the eyes; the antennae scarcely extending to the middle of the elytra, filiform in the male, shorter and the terminal joints thicker in the female insect, the lower five joints |
