Show 1887.] PHYTOPHAGOUS COLEOPTERA OF CEYLON. 103 than the others, but none extend to the end of the elytra nor to the middle. The shoulders are but little prominent, and between them and the lateral margin of the elytra there is a broader impunctate space extending to the middle, the lateral margin itself being accompanied by a row of deep punctures. Tbe legs are subject to some variation in colour, being sometimes dark fulvous, but the anterior tibise seem to remain testaceous. AULACOPHORA STEVENSI, Baly. (Plate XI. fig. 1.) Testaceous ; head and thorax impunctate ; elytra finely punctured; a sutural and submarginal narrow stripe, as Well as their extreme apices, black. 6 - The fourth joint of the antennae strongly swollen and elongate. Length 3 lines. Head rather swollen at the vertex, impunctate, the frontal tubercles narrowly transverse. Antennae more than two thirds the length of the elytra, entirely testaceous, the second joint extremely short, the third and fifth joints triangularly dilated in the male, the fourth greatly enlarged in the same sex, the rest of nearly equal length and slender. Thorax transverse, the sides rather deflexed and widened towards the apex, the surface with a deeply impressed transverse groove near the base, impunctate. Scutellum black. Elytra rather convex and gradually widened posteriorly, extremely finely and rather closely punctured, a narrow sutural stripe extending to the apices and round the latter, and another equally narrow stripe near the lateral margin, commencing at the base and abbreviated before the apex of each elytron, black. Legs and underside entirely testaceous. The female only differs from the male in having simple antennse. Bogawantalawa. AULACOPHORA NIGRIPETA, Duviv. (Plate XI. figs. 2, 3.) PHYLLOBROTICA HIRTIPENNIS, sp. nov. Obscure piceous or black below; basal joints of the antennse, the head, thorax, and the femora fulvous ; elytra obscure testaceous, finely rugose and pubescent, the margins narrowly fuscous. Length 1| line. Head impunctate ; the frontal tubercles distinct but small; palpi robust. Antennse two thirds the length of the body, piceous, the three basal joints fulvous. Thorax transverse, the sides slightly constricted at the base, the disk rather deeply transversely depressed, impunctate. Elytra very obscure pale or darker testaceous, sometimes fuscous, the suture and the lateral margin at the shoulders darker ; the surface slightly rugosely punctured and moderately closely covered with stiff whitish hairs; their epipleurae extremely narrow. Tibiae unarmed, fuscous ; the first joint of the posterior tarsi as long as the two following joints together ; the anterior coxal cavities open. Nuwara Eliya. The legs are sometimes entirely fulvous, but generally the femora only are of that colour. |
