Show 1887.] PHYTOPHAGOUS COLEOPTERA OF CEYLON. 87 EUCYCLA CEYLONENSIS, Sp. nOV. Fulvous; antennae black, the basal joint fulvous ; thorax closely punctured, with or without a black basal spot; elytra strongly punctate-striate, the interstices finely punctured, black, the suture narrowly and the apices more broadly fulvous. Var. a. Black, the first five joints of the antennse flavous. Var. b. Smaller ; piceous, the elytra fulvous. Length 1-1 i line. Head nearly impunctate, fulvous. Antennae with the first joint long and slender, curved, the second short and thick, the four following joints still shorter and nearly equal in length, the rest widened and compressed. Thorax more than twice as broad as long, the posterior margin broadly produced at the middle, the sides straight; the surface distinctly and very closely punctured, fulvous, sometimes with a central black spot widened at its base. Scutellum obscure fulvous. Elytra very convex, black with a greenish tint, strongly and regularly punctate-striate, the interstices very finely and sparingly punctured, the apices, in shape of a triangular spot, and the suture very narrowly and rather obscurely fulvous ; anterior coxal cavities open. The slender and elongate first joint of the antennse, the lobed thorax, punctate-striate elytra, and general rounded and convex shape seem to m e to place the present insect in Baby's genus Eucycla. Thrylaa of this paper has the general appearance and the punctate-striate elytra of the present insect, but may- be known by the less transverse thorax and the much shorter basal joint of the antennse. LONGITARSUS LONGICORNIS, Sp. nOV. Ovate, convex ; obscure testaceous ; antennae much longer than the body; thorax impunctate; elytra scarcely visibly punctured; the apices of the posterior tibiae piceous. Length 1 line. Head rather broader than long, entirely impunctate; the frontal tubercles scarcely indicated ; labrum and palpi piceous. Antennae one half longer than the body, entirely testaceous, the third joint distinctly shorter than the fourth. Thorax about one half broader than long, the sides slightly rounded and constricted near the base, the anterior angles obliquely truncate, the surface entirely impunctate. Scutellum broader than long. Elytra ovate, narrowed near the base and the apices, extremely minutely punctured, only visible under a very strong lens, of a darker colour than the thorax ; underside and legs testaceous; the apical half of the posterior femora piceous ; the first joint of the posterior tibise rather longer than the three following joints together. Bogawantalawa. The very long antennse, ovate shape, and the nearly impunctate upper surface are the distinguishing characters of L. longicornis. In one specimen the legs are of an entirely testaceous colour, but all the other characters are the same as in the type. |
