Show 1903.] SOUTH-AMERICAN COLEOPTERA. 47 transverse metallic green bands, one below the base, the other, of oblique shape, at the middle. Length 10-11 millim. Head minutely and closely punctured, obscure aeneous, opaque ; antennae short, black, the basal two joints below and the apex of the last flavous; thorax about twice as broad as long, the sides straight at the base, rounded anteriorly, the anterior angles mucronate, extending to the end of the eyes, the extreme lateral margins flavous, the disc coloured like the head, very closely and finely punctured, the punctation even throughout ; scutellum black; elytra pale testaceous, closely, strongly, and irregularly punctured, covered with numerous, closely placed, green, small spots of irregular shape and size, below the base a narrow transverse metallic green band extends across the suture but not to the lateral margins, another similar band of strongly oblique direction is placed at the middle and is slightly abbreviated at each end; mesosternal process long and robust. Hab. Peru. (Two specimens.) Several similarly marked species are known, but they are either of much larger size or devoid of the thoracic flavous margins ; in D. bifasciata Fab. and D. macidata Oliv. the anterior elytral bands are curved upwards and the suture is likewise provided with an aeneous stripe ; the elytral epipleura? in the present species are entirely flavous. DORYPHORA FASCIATIPENNIS, Sp. nOV. Greenish aeneous, the thorax remotely punctured ; elytra closely geminate punctate-striate, a subsutural and marginal longitudinal narrow stripe, connected by a transverse one below the middle, flavous. Length 8 millim. Head finely and sparingly punctured ; antennae greenish aeneous, the terminal joints moderately widened, twice as long as broad ; thorax sparingly punctured at the middle, the sides impunctate ; elytra evenly convex, strongly and closely geminate punctate-striate, the first two rows near the suture, single, the flavous bands narrow, the sutural one placed on the third interspace, the lateral one close to the margin which remains of the ground-colour, both bands are joined at the apex and connected below the middle by another short transverse band ; the mesosternal process very short, claw-ioints unarmed. Hab. Balzapamba, Ecuador. A small beetle, resembling in its markings several species of the genera Zygogramma and Cosmogramma, but a true Doryphora. STILODES FLAVOFASCIATA, sp. nov. Black, the labrum, palpi, and basal joints of the antennae flavous ; thorax opaque, nearly impunctate ; elytra similarly sculptured, black a narrow transverse and finely divided band at the base, • |
