16 PROCEEDINGS OP THE ACADEMY OP [1886. 



inner margin. Hind wing immaculate. Length to end of wings 

 about 5 "5-6 mill. 



Rhode Island and Pennsylvania. From two specimens col- 

 lected many years ago by Dr. Joseph Leidy in Rhode Island, 

 and two specimens taken by myself near Philadelphia, on the 

 trunks of chestnut trees, where they appeared to be solitary. 

 For some time I had, somewhat doubtfully, supposed this species 

 to be Pa. canadensis, of Prov., until I received a letter from Dr. 

 Hagen, referring canadensis to the genus Elipsocus. 



Fsoous texauus. 



Pale yellow, with brown markings. Antennae longer than the 

 wings, fuscous, pale at the base. Nasus lineated with brown ; rest 

 of head above with irregular markings, viz. : a horseshoe spot 

 before the ocelli, an irregular line on each side from near the 

 base of the antennae to the ocelli ; a line of spots within the 

 margin of the eye, occiput with a line of spots on each side of the 

 dividing suture that come together just behind the ocelli. Eyes 

 brown, with a slight golden tinge ; ocelli black. Lobes of the 

 mesotiiorax clouded with fuscous, the sutures pale yellow. Abdo- 

 men marked with fuscous, and the anal appendages yellow. 

 Legs luteous, the apical tarsal joints fuscous. Wings hyaline, 

 the veins brown ; pterostigma less clear, a fuscous spot within 

 its apical half, and another just below it ; a fuscous band crosses 

 the entire wing in the middle, its outer margin reaching from the 

 base of the pterostigma to the junction of the cubital and post- 

 costal veins and the posterior margin, passing through the basal 

 angle of the discoidal cell. Hind wings hyaline, no markings. 

 Length to end of wings about 4 mill. 



Var. submarginatus. Plate I, fig. 1. 



Characterized b}^ having the fore wings with additional mark- 

 ings in the form of a submarginal fuscous band or cloud, 

 reaching from the second apical nervule to the posterior apical 

 extremity of the discoidal cell, and with a few somewhat 

 rounded spots between the nervures bordering upon and beyond 

 the discoidal cell. Length about 3 mill. Otherwise like texanus. 



Southern Texas. I took fifteen specimens of texanus and four 

 of var. submarginatus entirely by beating from yellow berry 

 bushes, black chaparral and live oak, over the prairies. It is 

 probably the commonest species in its locality.
