Show 94 MR. M. JACOBY ON THE [Feb. 1, indicated only near the middle by a thickened rounded fovea; the surface scarcely visibly punctured. Elytra very convex, deflexed and pointed at the apices, without any basal depression or prominent shoulders, the surface punctured like that of the thorax. Body below coloured like the upper surface; the tibiae and the tarsi more or less distinctly flavous. Dikoya, Bogawantalawa. PH^ELOTA (gen. nov. Halticinorum). Body ovate, convex, subcylindrical, pointed posteriorly. Antennse rather distant, gradually thickened at the terminal joints. Thorax transverse, the sides rounded, the anterior angles thickened and obliquely rounded, the disk without depression. Elytra punctate-striate. Anterior tibise unarmed ; the posterior ones with a very short spine, somewhat widened at their apices, and with a short and shallow longitudinal depression or groove ; the first joint of the posterior tarsi as long as the two following joints together ; claws appendiculate. Prosternum broad, its base truncate. Mesosternum of the same shape but half the size. Anterior coxal cavities closed. Phcelota, like Chabria, has much the general appearance of a species of Chrysomela; from Chabria it differs in the shorter antennae, the punctate-striate elytra, and the closed coxal cavities. PHCELOTA SEMIFASCIATA, sp. nov. Fulvous or piceous; above obscure greenish aeneous varied with fulvous; thorax minutely punctured, the disk greenish ; elytra regularly punctate-striate, greenish seneous, the interstices alternately more or less obscure fulvous. Var. Above and the legs entirely fulvous (immature ?). Length 2 lines. Head with a few minute punctures ; eyes large ; frontal tubercles transversely trigonate, nearly contiguous; the carina indistinct; labrum more or less fulvous. Antennse half the length of the body, the five lower joints fulvous, the rest black, the apex of the terminal joint fulvous ; the second to the fifth joints short, nearly equal, the six terminal ones thickened, slightly longer than broad. Thorax transverse, the anterior margin nearly straight, the posterior one and the sides slightly rounded, the anterior angles much thickened and obtusely rounded, the surface minutely punctured, greenish seneous, the margins more or less fulvous. Elytra very convex, subcylindrical, and pointed at the apices, strongly punctate-striate. Legs piceous or fulvous, more or less stained with greenish aeneous. Bogawantalawa. In some specimens the elytra show alternate longitudinal bands of seneous and fulvous. PEXODORUS (gen. nov. Halticinorum). Body ovate, widened behind; palpi slender, filiform. Antennse filiform, the second joint short, the third and fourth joints equal. |
