Show 1897.] PHYTOPHAGOUS COLEOPTERA OF AFRICA. 255 Length 1|-1| line. Head black, finely rugosely punctured and sparingly pubescent; antennas rather short, entirely black, the third and fourth joint equal, the terminal joints slightly widened ; thorax with moderately rounded sides, the posterior angles not much produced, the entire surface finely rugose or wrinkled, making the punctuation very indistinct, black, the anterior margin very narrowly and the sides broadly flavous, the yellow colour at the latter place separated from the black portion by a strongly sinuate margin ; scutellum very broad, its apex pointed, minutely punctured, black; elytra with regular and deep rows of punctures, the interstices very finely transversely wrinkled, flavous, the shoulders with a black spot, the suture with a broad black band, which widens strongly at the base, so as to very nearly join the shoulder-spot, below the middle the band narrows, but again gets slightly wider near the apex, to which it does not quite extend, the extreme lateral margin from below the base and the apical one are likewise black ; the pygidium, underside, and legs are entirely of that colour. Hah. Mashonaland (67. Marshall) ; coll. Brit. M u s . and m y own. A well-distinguished species, on account of the sculpturing and pattern of its thorax and elytra. CRYPTOCEPHALUS NATALENSIS, n. sp. (Plate XVII. fig. 8.) Dark fulvous ; thorax longitudinally strigose, its margins flavous ; elytra deeply and closely punctured, the interstices longitudinally costate and with yellow short stripes. Length 1| line. Head with some strong punctures and a central groove at the vertex fulvous ; antennas extending to about the middle of the elytra, black, the lower four joints fulvous, third aud fourth joint equal, the fifth more elongate, the following joints slightly shorter; thorax proportionally long, the sides straight, narrowed in front, the entire surface covered with longitudinal strigas, dark fulvous, the margins narrowly flavous, the sides more broadly so and the base with two very narrow flavous spots ; scutellum broadly truncate at its apex, flavous, margined with piceous ; elytra slightly narrowed posteriorly, closely impressed with large, deep, and transversely-shaped punctures, the interstices strongly costate, those near the suture of sinuate shape, fulvous; every alternate costa with two or three bright yellow stripes of various length, those at the apex and at the extreme margins nearly entirely of that colour; underside and legs entirely fulvous, the latter robust. Hab. Natal (my collection). Of this species I have n o w seen two specimens, which I formerly referred to C. aratlcollls, Chap., from Zanzibar; with this it entirely agrees in the unusual and interesting sculpturing of the thorax and the elytra : the eyes are likewise closely approached at the top of the head as in Chapuis's species ; but as this author says nothing about the yellow margins of the thorax nor of the similarly- |
