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 mar- 

 gins 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 ^^■hich 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 3g mm. ; width of pronotum 1| mm. 



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. 



Aphelonotus, gen. nov. 



Oblong-oval, acute at both ends, pubescent. Closely related to 

 Pachynumus, King, but having minute ocelli deep-seated and placed 

 inside very near to the eyes. Head hardly longer than the pro- 

 notum, subcylindrical before the eyes, the vertex between the 

 eyes forming a stout convex lobe, inserted in the thorax almost to 

 the base of the eyes. Eostrum wide and depressed at base, reach- 

 ing 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 cyUndrical, 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, collar- 

 like 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
