JACOBY ON N E W [Dec. 16, This species may be distinguished from L. bicincta, Lac, and others similarly marked, by the colour of the antennae and the distinct basal depression of the elytra. 2. LEMA NICARAGUENSIS, sp. nov. Elongate, parallel. Head and thorax ferruginous; antennae (base excepted), breast, tibiae, and tarsi black ; elytra bluish black, the lateral margins, a transverse median band, and the apex flavous; femora and abdomen testaceous. Length 3 lines. Hab. Chontales, Nicaragua. Head not constricted behind the eyes, with a transverse and a median groove at the vertex, entirely impunctate, shining ferruginous, epistome black; palpi and the two basal joints of the antennse ferruginous, the other joints piceous, the apex of each joint fulvous. Thorax subquadrate, the sides moderately constricted behind the middle-; surface distinctly transversely grooved near the base, with two rows of small punctures placed longitudinally on the disk, rest of the surface smooth, shining ferruginous. Elytra deeply punctate-striate anteriorly, the punctuation gradually diminishing, but remaining distinct to the apex, the interspaces near the latter slightly costate ; a rather obsolete transverse depression is placed below the base ; the colour is a dark bluish black, the lateral margins, a transverse median band not quite touching the suture, and the apex flavous. Abdomen and the femora testaceous; breast, tibiae, and tarsi black. This species bears a close resemblance to several others described by Lacordaire and Clark, from all of which, however, it differs in the coloration of one or other parts. It is most nearly allied to L. placida, Lac, and L. violaceo-fasciata, Clark. The colour of the femora and of tbe apex of the elytra distinguishes it from the first species, while it differs from the last by the red head and the colour of the antennas; it may, however, turn out to be a variety of one or the other. 3. LEMA ANTENNALIS, sp. nov. Elongate, parallel; chestnut-coloured, variegated with piceous. Antennae short, the joints transverse, black ; elytra piceous, margined with brown, punctate-striate, intervals finely rugose. Length 3 lines. Hab. Zapote, Guatemala. Head impunctate, lower part of face sparingly fulvous-pubescent; eyes deeply emarginate : antennae short and robust, only reaching to the base of the elytra ; three basal joints brown, shining ; the rest black, closely pubescent; first joint swollen, round ; second of the same shape, shorter ; third half as long again as the second ; the following joints gradually widened, transverse, broader than long. Thorax without transverse basal depression, subquadrate, brown, shining, obsoletely streaked with piceous, surface minutely punctured. Elytra deeply punctate-striate anteriorly, the punctuation diminishing |
