Show 170 MR. M. JACOBY ON NEW [Mar. 2, Head finely punctured; labrum testaceous ; antennae extending slightly further than the base of the thorax, their last seven joints black. Thorax more than three times as broad as long, widened in the middle, the anterior margin nearly straight; surface irregularly and deeply but not closely punctate, the sides scarcely closer punctured than the disk. Scutellum impunctate. Elytra convex, nearly four times as long as the thorax, geminate punctate-striate, the punctures, however, not regularly placed and often interrupted, the interstices also very minutely punctured; each elytron with four black narrow stripes, the first running parallel to the suture, often obsolete and broken, the second and third from the base are abbreviated near the apex, the fourth near the lateral margin extending nearly to the end of the elytron. Underside fulvous; tibiae and tarsi lighter ; claws piceous. Collected by Mr. Belt. This species, although greatly resembling S. fuscolineata of Stall, is distinguished from the latter in not having the suture dark like the elytral stripes, and the puncturing not regularly arranged as in that species. In S. fuscolineata the punctured striae limit exactly the black elytral stripes and are deeply impressed, while in the present species the puncturing does not run regularly in pairs, and is often wider than the vittae, being besides that sometimes quite broken and finer. Collections of G o d m a n and Salvin and Jacoby. 10. STILODES STEINHEILI, sp. nov. (Plate XVIII. fig. 1.) Broadly ovate, moderately convex. Black ; head and sides of the thorax light testaceous, with a metallic greenish gloss ; elytra regularly punctate-striate, flavous, the sutural and lateral margins and two large patches, one before, the other behind the middle of each elytron, metallic violaceous blue. Length 4 lines. Hab. Columbia. Head flat, impunctate, separated from the clypeus by a distinctly angulated transverse groove ; lower part of face, a narrow median line running upwards to the base and sides of the latter, dark brown ; rest of the surface light testaceous with an iridescent gloss ; antennae extending to a little beyond the base of the elytra, black, basal joint testaceous beneath, the third joint as long as the first two united, the apical joints gradually widened. Thorax three times as broad as long ; its sides straight at the base, rounded from the middle to the apex ; posterior margin widened towards the middle ; surface distantly but distinctly punctured, sides impunctate and coloured like the base of the head, forming a broad band, the posterior portion of which is greatly narrowed and sharply limiting the rest of the black surface. Scutellum oblong, black. Elytra comparatively flat, regularly striate-punctate ; each elytron with ten rows of punctures, the first short; interstices smooth, flavous or testaceous, with the sutural and lateral margins violaceous blue, the former being wide at the base and gradually narrowed posteriorly ; a large patch |
