Show 264 MR. c. o. W A T E R H O U S E O N [Feb. 15, Stenispa, but differ from them and from the species of Cephalolia in having a small acute frontal tubercle, and in having a raised inner margin to the eyes. 17. HOMALISPA CRIBRIPENNIS, n. sp. (Plate XXX. fig. 1.) H. nigra; capite thoraceque flavis, elytris cyaneis, for titer crebre punctatis. Long. 3 lin. Head obscure yellow, dusky about the eyes. Thorax at the base about two fifths broader than long, very obliquely narrowed anteriorly, impunctate, shining, convex on the disk, impressed at the sides; the anterior angles acute, but very slightly prominent; the sides very slightly arcuate, nearly straight; the posterior angles very acute ; the base widely sinuate on each side. Scutellum black, smooth. Elytra deep blue, shining, moderately convex, a little broader than the thorax, subparallel, obtusely rounded at the apex ; very strongly and closely punctured, the punctures near the sutures forming lines; the apical margins are very finely crenulate. Abdomen fulvous. The base of the anterior femora is yellow. A second specimen has the abdomen and the anterior legs entirely black. The specimens are probably sexes. This species may be placed near H. javeti, Baly; but the confused punctuation of the elytra separates it from all the species known to me. 18. HOMALISPA COLLARIS, n. sp. (Plate XXX. fig. 2.) H. nigra, nitida ; thorace pallide flavo, elytris striato-punctatis, vix cyaneo-tinctis. Long 3| lin. Thorax about two fifths broader than long, slightly narrowed in front, gently convex on the disk, a little impressed within the posterior angles, shining and impunctate, pale yellow, with the anterior margin black in the middle; the base in the middle and the fine incrassated basal margin are also black ; the anterior angles are very little prominent and are moderately obtuse ; the sides are gently arcuate in front of the middle, straight (or only extremely gently sinuate) behind ; the posterior angles slightly diverging and very acute. Scutellum smooth. Elytra distinctly broader than the thorax, elongate-oblong, moderately convex, a little narrowed at the base, parallel at the sides, obtusely rounded at the apex ; black, with an obscure tint of dark blue, with lines of rather fine but distinct punctures, the interstices smooth; the punctuation obscure and irregular at the apex; the margins are impressed below the shoulders and a little reflexed ; the apical margins finely crenulate. Underside of the prothorax and the base of the anterior femora yellow. 19. ALURNCS BATESII, Baly, Ann. & Mag. N. H. 1864, vol. xiv. p. 334. The specimens brought by Mr. Buckley differ from that described by Mr. Baly from Ega in having no bla'ck spot on the shoulder of the elytra. |
