palpi (fig-. 4 c) 4-jointed, and scarcely longer than the lobe ; the mentum is subeordate, the labium obtusely
pointed at the tip, and the labial palpi small and 3-jointed, the middle joint the shortest (fig. 4 4). The hind
Ibraora are moderately incrassated, without any spine on the under margin ; the hind coxoe are produced into
a small spine near the tip of the outer margin. The antennoe are inserted just above the mouth widely apart,
the basal joint received, when at rest, in an oblique channel of the face between the eyes.

SPECIES 1—CHRYSEIDA SUPERCILIOSA. Spinola.
The tj-pe of this Genns, from Cayenne, is described as a male, and is remarkable for the great development
of the prostcrnum, which is concave on its upper side, ' formant une espèce de cuiller au fond de laquelle,
la tête se retire en partie quand elle se repose, et où elle peut enfoncer toutes les parties de la bouche.'
The antenna; are 11-jointed; the second joint is, however, very minute, the five following cylindrical and
elongated, and the four terminal ones much shorter, forming an elongated mass.

The antenna; in the specimen figured are 11-jointeii, but the second joint is very short, the third annuliform

an oval mass not larger than the preceding joint.

The head and collar of this very beautiful insect are green, finely punctured; the mesonotum is green with
a large coppery-purple spot in front, and a larger one between the parapsides, the sides of which are tino-ed with
the same coppeiy-purple, wliich is also the colour of the large scutellum, which is marked with two oval o-.een
spots. 11,e abdomen is chalybeous, very glossy, and varied with green and coppery-red and orange, of vvhich
colours are two large spots on the fifth and sixth segments of the abdomen; the sixth segment has a lar^e
spiracle near each of the anterior lateral angles. The antenna (fig, 6«) have the basal joint long, the second
nod rately long and slender the third and following gradually becoming shorter and somewhat broader, the
