Show 1897.] PHYTOPHAGOUS C O L E O P T E R A O P APRICA. 259 before him in which the white colour of the clypeus &c had become discoloured. The variety I mention has not been noticed by Suffrian, and m y description of the spotted form is considered by him to represent a rare variety ; that the Natal insect may, however, prove to be of another closely allied species is not impossible. CRYPTOCEPHALUS UNICINCTUS, n. sp. Black, the base of the antennas and the tibias more or less fulvous; thorax very minutely punctured, fulvous, with more or less confluent black bands ; elytra strongly punctate, the insterstices finely punctured, fulvous, the margins narrowly and a short lateral stripe black. Length 2 lines. Head strongly rugose and finely pubescent, black; antennas extending beyond the middle of the elytra, black, the lower five joints fulvous, the second and third joints short, nearly equal, terminal joints rather elongate, shorter in the female as well as the entire antennas; thorax strongly narrowed in front, the sides but slightly rounded, the disc very minutely and irregularly punctured, reddish fulvous, the sides occupied hy two broad black bands of variable width, often connected with another small black spot near the margin, but as frequently separated from it and narrower; scutellum not longer than broad, black; elytra with deep rows of slightly transversely-shaped punctures, the interstices also with a single row of minute punctures, the basal, sutural, and lateral margins (the latter at the posterior portion only) black, the surface pale fulvous, with a short black band from the shoulder to below the middle placed between the seventh and ninth rows of punctures; underside and pygidium black, finely pubescent; the prosternum, mesosternum, and a spot between the posterior coxas yellow; legs black, the tibias more or less fulvous at the base and apex. Hab. Natal, Estcourt (67. Marshall). The single elytral stripe at the sides and the rugose and black head, as well as the other details pointed out, will separate this species from any of its African congeners. I have seen four specimens only, varying in the amount of black on the thorax and legs. CRYPTOCEPHALUS BIMACULICOLLIS, n. sp. (Plate XVII. fig. 12.) Fulvous, thorax impunctate, the disc rufous, the margins flavous, the base with two black spots; elytra finely punctate-striate, yellow, a transverse band at the base and a narrower one near the apex black. Length 2 lines. Head with a few fine punctures, the vertex fulvous or piceous, the lower portion flavous ; labrum and palpi testaceous ; antennas extending to the middle of the elytra, shorter in the female, the lower five or six joints flavous, the others fuscous, third joint but slightly longer than the second, terminal joints elongate: thorax strongly narrowed in front, the sides nearly straight, the 17* |
