Show 608 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA. [N< 91. M O N O C E S T A SPLENDIDA, Clark. Six specimens of this handsome species were collected ; they differ slightly from the type in the metallic blue (not green) colour of the elytra and underside, as well as in the somewhat stronger punctuation of the former parts. Genus CHTHONEIS, Baly. 92. C H T H O N E I S APICALIS, sp. nov. Elongate, widened posteriorly. Black; elytra finely and closely punctured, fulvous, their posterior half dark blue. Length 5 lines. Head distinctly punctured at the vertex, the latter obscure rufous, deeply transversely grooved between the eyes ; antennse half the length of the body, black ; first and fourth joints of nearly equal length and the longest, second and third joints subequal, the rest subdepressed, widened. Thorax subquadrate, broader than long, the angles thickened; surface irregularly depressed, closely and rather strongly punctured; scutellum black, triangular. Elytra widened from base to apex, moderately convex, very closely and rather finely punctured, the interstices slightly wrinkled, the anterior portion to a little below the middle fulvous, the rest dark greenish blue, shining. Abdomen at the sides or entirely testaceous, rest of the underside and the legs black. Mus. Godman and Salvin, and Jacoby. I believe I am right in referring the above insect to Mr. Baly's Chthoneis, although the species before me is larger and more robust and the antennse shorter ; the open anterior coxal cavities, the compressed antennse, however, as well as the unarmed tibiae and the long first tarsal joints, agree well with the typical species belonging to Baly's genus.
