Soc. 1898, p. 214) from a specimen which had the ground-colour of the elytra testaceous, the suture, a small humeral and a larger subapical spot metallic blue. Since then I have received two specimens from Mr. Marshall, which agree in every detail excepting the colour of the elytra as given above. This will probably prove to be the normal form; the rather flattened thorax and the black head spotted with fulvous are the principal characters which distinguish this species. LEMA MALVERNEXSIS, sp. n. Reddish fulvous, the antenna?, apex of the tibia?, and the tarsi black ; thorax very closely punctured; elytra metallic blue, the extreme lateral margins and tlxe apex fulvous. Length 6 millim. Head distinctly punctured, with highly raised, posteriorly divided tubercles, the labrum black ; antenna? not very long, the basal joint fulvous below, the second and third very short, equal, the fifth and following joints of equal length, black ; thorax not longer than broad, strongly constricted at the sides below the middle, the anterior axrgles rather pointed when seen from above, the basal sulcus very deep, connected with the lateral fovea, the surface closely and finely punctured, with two longitudinal shallow grooves placed at the anterior portion near tlxe sides ; scutellum fulvous; elytra with a small fovea below the base near the suture, closely and strongly punctured, the interstices but slightly raised near the apex, the latter fulvous to a small extent as well as the thickened lateral margins; underside fulvous, clothed with fine yellow pubescence; legs fulvous, the apex of the tibiae and the tarsi black. Hah. Malvern, Natal. This Lema is evidently closely allied to Z. kolbei Weise (Wiegm. Arch. 1901, p. 156), but, according to the description, the thorax of that species is longer than broad and devoid of the two longitudinal grooves, and tlxe elytra are entix-ely blue. LEMA GERSTAECKERI, sp. n. Below, the head, antenna?, and legs black, above metallic dax-k blue ; thorax nearly impunctate, deeply silicate and bifoveolate anteriorly; elytra with a sutural depression, moderately strongly punctate-striate, the interstices at the sides and apex convex. Length 5 millim. Head bluish black, impunctate, with two highly raised elevations of elongate shape and divided by a deep groove, eyes deeply notched, clypeus finely punctured ; antenna? about half the length of the body, black, the third and fourth joints equal, the eighth to the tenth joint twice as long as broad, terminal joint more elongate ; thorax rather broader than long, the sides with a deep transverse fovea, bounded above by a longitudinal short ridge, immediately |
