Show 216 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA [Mar. 6, punctate-striate, the interstices convex, flavous, a broad transverse band at the base and another near the apex black. Length 4 millim. Head fulvous, impunctate, slightly uneven, the eyes nearly continuous at the vertex ; antennae extending beyond the middle of the elytra, black, the lower four joints flavous, the third and the following three joints gradually increasing in length, the terminal ones shorter; thorax twice as broad as long, slightly widened at the middle, fulvous, the basal margin narrowly black, the posterior angles flavous, the entire surface covered with longitudinal fine strigae without punctures, posterior margin finely serrate ; scutellum black, with a fulvous basal spot, its apex truncate ; elytra very slightly narrowed posteriorly, deeply and closely punctate-striate, the interstices strongly longitudinally costate, especially so at the sides, flavous, the base with a broad transverse black band, not quite extending to the lateral margins, another similar band is placed close to the apex, leaving the latter of the flavous groundcolour ; underside and legs pale fulvous, finely pubescent. Hab. Moliro, Africa (Duvivier). This is another of those species having the thorax closely strigose, which seem confined to Africa; the other two known species, C. araticollis Chap, and C. natalensis Jac, are devoid of elytral bands. I received the specimen from the Belgian Museum. CRYPTOCEPHALUS SALISBURIENSIS, sp. n. Head and the underside black ; thorax impunctate, flavous, with two large black spots ; elytra moderately strongly punctate-striate, flavous : a round spot on the shoulders, a sutural transverse spot at the middle, and a transverse band near the apex, black ; legs flavous, the femora spotted with black. Length 5 millim. Head black, distinctly punctured and sparingly pubescent; the clypeus and the sides of the face below the eyes yellow ; antennae slender, black, the lower five joints flavous, the basal joint black above; thorax with the sides straight or nearly so, otherwise of usual shape, the basal margin near the anterior angles distinctly toothed, the surface impunctate or with a few minute punctures, fulvous, with a large black oblong spot at each side, not extending to the anterior margin, the extreme basal margin likewise black, the other margins of the ground-colour ; scutellum black ; elytra rather finely punctate-striate, the interstices with some extremely fine punctures, flavous, the shoulders with a black oblong spot, the suture at the middle with another transverse short spot, a transverse band extending across the suture but not quite to the sides is also placed near the apex ; below black, the prosternum, mesosternum, and a spot at the base of the abdomen yellow, the posterior angles of the prosternum prolonged laterally; femora with a black spot at the middle.
