273 PENTATOMA RUTILANS. XIX. Fig. 2. Edessa rutilans, Fabr.—Cimex rutilans, Drury, Vol. iii. Pl. 46, fig. 5.

the present genus the scutellum is still large, but it covers only a portion of the abdomen. The antennæ have the first or radical joint shortest; the third joint sometimes longest, (as in Prufipes,) sometimes shortest, (as in P. Baccarum, and P. Grisea.) The second and third joints of the rostrum are rather longer than the others; anterior tibiæ notched before the apex; tarsi three-jointed, the middle joint minute. (Pl. XVIII. fig. 9.) The species of this genus are more widely distributed than their near allies the scutelleræ. Many brilliantly ornamented kinds inhabit the warmer regions of Asia, Africa, and America; no small number are to be found in the continent of Europe; and about fifteen are included in the lists of our indigenous insects. The beautiful species figured on Pl. XIX. at fig. 2. is a native of Sierra Leone. The thorax is bright mazarine blue, with a scarlet streak across the front; scutellum greenish blue, the tip and margins scarlet; hemelytra blue; abdomen scarlet, with dark blue spots at regular intervals along the sides; underside yellow; legs and rostrum black.
