Show 340 MR. M. JACOBY ON T H E [Mar. 7, legs as long as the following two joints together; prosternum extremely narrow. Hab. Salisbury, Mashonaland (G. Marshall). This species is very closely allied to P. pallida Jac. and P. gestroi Jac, both African ; it is, however, a more robust, larger and convex insect, the sides of the thorax are less rounded and the antennas are shorter : from P. lactea Jac. the uniform flavous antennas and much narrower thorax distinguish it. I received several specimens of it from Mr. Guy Marshall. PHYGASIA MARGINATA, sp. n. Flavous, the head and thorax im punctate; elytra chestnut-broAvn, finely and closely punctured, the lateral margins flavous, narrowly reflexed. Length 4-5 millim. Head flavous, impunctate, the frontal tubercles small and thick, carina broad and strongly raised, mandibles and palpi fulvous; antennas rather robust, extending slightly beyond the middle of the elytra, flavous, all the joints thickened, the third and folloAving ones of equal length, terminal joint more elongate ; thorax twice as broad as long, the sides rounded and with a rather broad margin, the anterior angles obtuse, the posterior ones distinct, the base Avith a transverse sulcus bounded at the sides by a perpendicular groove, the surface entirely impunctate, flavous ; scutellum flavous ; elytra slightly wider at the base than the thorax, finely and closely punctured, with a narrow reflexed margin, the latter, the epipleuras, and the apex more or less flavous, the rest of the surface dark broAvn ; underside and legs fkwous. Hab. Cameroons (Conrad). Three specimens, which I received from Dr. Kraatz, agree in every respect: the species may be known by the system of coloration, Avhich differs from that of P. marginicoUis Jac. (sub Lactica) in the flavous head, elytral margin, and similarly coloured underside ; it is also of smaller size. PHYGASIA LACTEA, sp. n. Pale testaceous, the antennas (the basal three joints excepted) black; thorax impunctate, the basal sulcus distinct; elytra extremely closely and finely punctured. Length 5 millim. Head impunctate, the eyes large, tbe frontal tubercles rather feebly raised, interrupted at the middle, the palpi very robust; antennas black, the loAver three joints flavous, all the joints rather robust, the third joint very slightly longer than the fourth ; thorax transverse, more than twice as broad as long, the sides with a rather broad reflexed margin, rounded, the anterior angles oblique, posterior ones produced into a short tooth, tbe surface entirely impunctate, shining, the base Avith the usual sulcus deeply impressed and bounded at the sides by an equally deep longitudinal groove; elytra convex, not depressed below the base, distinctly |
