Mas, capitis basi profunde excavato-eroso, erosione ima tota nigra ; fronte elevata, in medio profunde sidcata. Antennis acute serratis, articulo quinto triangulari apice nigro. Femina, antennis brevioribus, leviter serratis. Hab. Willowmore, Cape Colony (Brauns). The head in the male is deeply excavated ; the surrounding parts are yellow and elevated, but very differently from either of the Hedybii described by me in the ‘ Annals and Mag.' for Jan. 1900*. The deep notch in the front part of this elevated edge of the crater is of itself sufficient to prevent its being confused with them. The base of the crater in the male and the base of the head in the female are black. The antennae are more acutely serrate than in any other species I have seen. They vary in the degree to which they are marked with black. Their second joint is very short, the third as long as the basal, the fourth and fifth triangular, the last in the male always black in its apical half and more acutely produced inwards; the following joints are longer, acutely serrate, and more or less dark, in the females I have seen always dark. The thorax is of the same shape as in H. amcenus, H. anceps, &c., but the disk is nearly all suffused with blue-black, two dark points project on the base, and it is sometimes indented on each side in front. The scutellum is black; the elytra are blue and often have a beautiful metallic-violet reflection, they are finely coriaceous. The legs are yellow but tinged with black, and the hind pair are altogether dark, in which respect this insect also differs from any of the Hedybii of this group described. Three males and two females of this species were sent me by Dr. H. Brauns. H e d y b iu s qitadricornis, sp. n. Oblongus, nigro cceruleus ; capite, prothorace pedibusque san-guineis; scutello et elytris viridibus, sericeo-pubescentibus; antennis rufis, articulis singulis (maris) nigro-notatis, femince articulis basi tribus rufis usque ad apicem infuscatis. Long. 4-4-5 millim. 3 $ • Mas, capite excavato-eroso, erosionis margine basali in cornu duplici quasi elevato, cornu anteriore apice ciliato, posteriore hamato apice nigro, supra oculos tuberculato. Femina, fronte deplanata, basin versus nigrescente. Hab. Willowmore, Cape Colony (Brauns). Head, thorax, base of the antennae, margins and apex of the abdomen yellow ; the scutellum and elytra are bluish green. The upper side is finely clothed with a pruinose silky pubescence, long hairs are absent. The head in the female and the front of the thorax in the male * Ann. & Mag. N. H . ser. 7, v. p. 81 (1900). |
