Show 1887.] PHYTOPHAGOUS COLEOPTERA OF CEYLON. 113 iENIDEA ? HIRTIPENNIS, sp. nOV. Obscure testaceous ; the two apical joints of the antennse fuscous ; thorax transverse, impunctate, biimpressed; elytra very finely semi-punctate- striate, sparingly pubescent. Length 2 | lines. Head with a deep fovea between the antennse, impunctate; terminal joint of the palpi thickened. Antennae but slightly shorter than the body, fulvous, the two or three terminal joints darker, second joint very short, the third nearly three times as long, and longer than the following joints. Thorax at least twice as broad as long, the sides very slightly constricted at the base, a little rounded before the middle, the angles not produced ; the surface impunctate, with a rather deep oblique impression at each side. Scutellum triangular. Elytra without basal depression, very finely and somewhat regularly punctured, the interstices here and there obsoletely raised and sparingly clothed with rather long and stiff hairs ; elytral epipleurae broad, continued below the middle. Tibise unarmed ; the first joint of the posterior tarsi as long as tbe three following joints together. Claws appendiculate. Anterior coxal cavities closed. Dikoya. I have placed this species in fEnidea, with which it agrees in all essential points. It is, however, possible that I may have only female specimens before me, and that the male insect, like several others of the genus, m a y differ in the structure of the head. The pubescence of the elytra distinguishes A. hirtipennis from any of its allies. CNEORANE PALLIDA, Sp. nOV. Oblong, pale testaceous ; antennae obscure fuscous ; thorax square-shaped, impunctate ; elytra scarcely visibly punctured. Length 2 lines. Head entirely impunctate, the frontal tubercles distinctly raised, divided and bounded behind by a deep groove; palpi robust. Antennse two thirds the length of the body, the second and third joints short and of nearly equal length, the fourth joint very slightly longer than the following ones, the three or four basal joints pale testaceous, the rest fuscous. Thorax slightly broader than long, all the margins straight; the surface very little convex, without depressions and punctures. Elytra rather convex, parallel and sub-cylindrical, the punctuation extremely minute and arranged for the greater part in closely placed rows. The tibiae unarmed, the first joint of the posterior tarsi as long as the two following joints together. Claws appendiculate. Anterior coxal cavities open. Bogawantalawa. In this species the third joint of the antennse is shorter than in C. elegans, Baly, and G. fulvicollis, Baly, being of the same length as the second joint; but in all other respects C. pallida agrees with its allies, and may be recognized by the uniform and very pale testaceous colour.
