of the thorax. In one specimen the abdomen is narrower than, in another 

 broader than, in a third of the same width as, the thorax. The first oblique 

 vein makes an angle with the postcostal of about fifty-five degrees and is 

 straight ; the second one of forty -five degrees and is sometimes straight, 

 sometimes arcuate, and the base of the first discoidal cell being very narrow 

 it is about four or five times broader on the hind margin than there. 



Length of body, 2.75-4""° j of fore wing, S.S-S.S""", the last partly 

 estimated.

2. Sbenaphis uhleri. 



Body large, stout, the head and thorax darker than the abdomen, which 

 is broader than they. Wings three times as long as broad, the postcostal 

 straight, thickened uniformly, and running into the very long and consider- 

 ably fusiform stigma. First oblique vein straight, set at an angle of fifty- 

 five degrees with the postcostal ; the second oblique vein sinuous, placed at 

 an angle of forty-five degrees with the postcostal ; the two veins moderately 

 close only at base, so that the first discoidal cell is four or fi ve times broader 

 on the hind margin. Cubital vein faint at base but originating about twice 

 as far from the second ol)lique vein as that from the first, arcuate on its 

 basal half, straight and longitudinal on its apical, occupying with its branches 

 the middle of its allotted space, first forking at less than one-third the dis- 

 tance to the hind margin, again opposite the base of the stigmatic vein and 

 less than half-way from its own first fork to the apex of the wing; in its 

 passage it approaches the stigmatic only a little more closely than the second 

 oblique vein. Stigmatic vein parting very slightly and gradually from the 

 stigma, so that the stigmatic cell is very narrow and about one-third the 

 length of the wing. 



Length of body, 4.75°"° ; of fore wing, 6.75°'°' ; breadth of same, 2.25"". 



Dedicated to my good friend, Mr. Philip R. Uhler, without whose 

 faithful and disinterested work the student of American Hemiptera would 

 be sadly at a loss. 



Florissant. Two specimens, Nos. 2327, 11202.
