Show 1894.] COLEOPTERA OF THE GENUS CEPTONYCHIS. 613 anteriorly ; elytra closely and distinctly punctured, pale flavous, the lateral and sutural margin, a transverse band at the base, and another below the middle ferruginous. Length 2 | lines. Head impunctate, ferruginous, shining, the frontal elevation scarcely raised, the carina acute; antennae short, black, the lower two joints more or less flavous, tbe fourth joint very elongate, quite double the length of the third, the following joints short, equal; thorax but slightly narrowed anteriorly, the sides nearly straight, the anterior angles not produced outward, the surface impunctate, yellowish white, the anterior margin with a ferruginous spot at the middle; scutellum fulvous; elytra closely and rather strongly punctured, of the same colour as the thorax, the base with a narrow transverse brown band, which is connected by the lateral and sutural margins with a similar band below the middle, these bands have a slight tinge of purple; if the dark colour is taken for tha.t of the ground, the elytra may be described as brown with a large discoidal ovate spot and the apex whitish; underside and legs ferruginous, tibiae and tarsi rather darker. Hab. Sta. Catharina, Rio Janeiro, Brazil; also Bolivia. ffiPIONYCHIS CRUCIFERA, n. sp. (Dej. in litt.). Black; thorax flavous, impunctate; elytra finely punctured, metallic blue, a rounded spot at the base and a more transverse one below the middle, not extending to either margin, flavous. Length 3 | lines. Head entirely black, scarcely punctured ; antennae nearly extending to the middle of the elytra, black, the intermediate joints slightly widened, the third joint only half the length of the fourth; thorax three times broader than long, flavous, the sides broadly flattened, bounded within by a deep longitudinal groove, the lateral margins rounded in front, the anterior angles dentiform, the surface impunctate; scutellum black; elytra widened at the middle, broadly margined, the shoulders prominent, bounded within by a deep depression, very finely punctured, the apex impunctate ; underside and legs black, the last abdominal segment of the male with a broad, rounded, and produced medial lobe. Hab. Brazil. If the flavous colour of the elytra is taken as the ground-colour, the blue portion extends across the middle in shape of a narrow and somewhat oblique band, and a triangular patch is placed at the apex, all the margins are also narrowly blue; the epipleurse are flavous within, bluish at the outer margin. The species named by Clark (E. murrayi, in his Catalogue, does not differ from the present one except in the black, not blue, elytral markings. QJIPIONYCHIS CRUX-NIGRA (Chevr. in litt.).
