UHLER ON T H E [Mar. 6, the middle line; the anterior lobe about twice as long as the posterior, strongly convex, indented each side anteriorly, with a distinct contracted double collum in front, the incision behind it deep and distinct; the posterior lobe a little more than half as long as the anterior, but much wider, arched, with the lateral margins almost abruptly oblique, indented next the humeri. Scutellum dull black, depressed, with the margins and tip a little raised. Legs stout, bristly, the femora thick, the anterior pair armed behind the middle with a sharp piceous tooth, before which rows of very fine teeth run out to the tip ; tip of tarsi piceous. Sternum and pleural pieces blackish piceous, remotely pubescent. Hemelytra pubescent, bright yellow from base to near the apex of corium ; the clavus, inner margin and tip of the corium, and the cuneus piceous black; membrane tinged with smoke-brown. Venter closely yellowish pubescent, margined on the submargin with a piceous curved line. Length to tip of venter 3 | m m . ; width of pronotum 1| m m. Only one specimen of this interesting species was obtained. It was captured at Balthazar, on August 8, at an altitude of 250 feet, in an open field, where it was shaken from piles of decaying weeds. A P H E L O N O T U S , gen. nov. Oblong-oval, acute at both ends, pubescent. Closely related to Pachynumus, Klug, but having minute ocelli deep-seated and placed inside very near to the eyes. Head hardly longer than the pronotum, subcylindrical before the eyes, the vertex between the eyes forming a stout convex lobe, inserted in the thorax almost to tbe base of the eyes. Bostrum wide and depressed at base, reaching but a little way upon the sternum, the second and third joints much less thick. Antennae about as long as the hemelytra to tip of membrane ; the basal joint fusiform, shorter than the head; the second cylindrical, about twice as long as the first, a little more slender; the third shorter, about equally thick, attenuated at base ; the following joints setaceous, set with erect long hairs. Prothorax transverse, subluniform, with a broad, contracted, collarlike apex, which is followed on the middle by a clearly bounded wedge-shaped callosity, behind this an impressed line continues to the transverse posterior suture; middle lobe moderately convex, with the sides a little decurved and bordered with a blunt carina, the sides before this contracted and indented ; the posterior division is quite narrow, flat, less coriaceous than the other parts, and on the sides separated from the preceding lobe by a deep incision behind which the margin is callous; posterior margin broadly sinuated, with the humeral angles a little produced backward. Scutellum triangular, longer than wide, a little reflexed at tip. Anterior femora sublenticular, compressed, armed beneath with rows of short teeth; the tibia of this pair slender, curved, carrying a little spongiole beneath the tip, the other legs simple, bristly. Prosternum simple; mesosternum with a short carina, followed |
