Three specimens. San Antonio, Texas, Dr. Win. Barnes. 

 This species much resembles E. atomosana Fern., but can readily 

 be separated, as the direction of the strijies are reversed. 



Eucosma briglitonana sp. uov. 



Expanse 13-16 mm. 



Head, palpi and thorax grayish-brown ; palpi, abdomen and legs fuscous. 



Forewing : gray-brown ; a large dark brown spot on dorsum, between inner 

 fourth and middle, extending to middle of wing, pointed on top, rounded on 

 sides; a smaller spot of same shape and color on dorsum before angle; from the 

 middle of costa an irregular narrow fascia goes obliquely to middle of wing at 

 end of cell, sending a wavy line down to the dorsal spot before angle. Beyond 

 this is a paler gray brown fascia, beginning on fascia as a germinate spot, broad- 

 ening below until it involves all of the ocellic space. Beyond it on costa are three 

 paler geminate streaks. A darker shade in apex. Cilia dark gray. 



Hindwing: smoky fuscous, cilia brownish-gray; underside of both wings the 

 same, with a dark spot in apex of forewing. 



Seven specimens. New Brighton, Pa., July 29th to Aug. 10th ; 

 all collected by F. A. Merrick. 



Eucosma tandana sp. nov. 



Expanse 20-22 mm. 



Head, palpi, antenna and thorax grayish-brown, patagia whitish posteriorly; 

 abdomen brownish-white; legs yellowish-white. 



Forewings: grayish-brown, darker on the male fold, and the trace of a darker 

 fascia from middle of costa; the costa in the outer half is faiutly strigulated with 

 brown. These marks are all very faint and inconspicuous. There are two 

 prominent dark brown spots; one before the middle of wing, resting on dorsum, 

 its upper end touching fold, it is about as wide as long and slightly rounded on 

 the sides; in one specimen a streak of brown is continued up above middle of 

 wing and connecting with the obscure central fascia. The other spot is in the 

 apical end of the wing ; it rests on costa before apex and extends down nearly to 

 anal angle, it is nearly straight on its outer edge and convex on its inner edge, 

 its length is twice as long as its width on costa, there is a narrow line of ground 

 color between the upper two-thirds of its length and termen. Cilia gray-brown. 



Hindwing: smoky brown, cilia paler; underside gray-brown, a shade darker 

 along costa. 



Underside forewing: smoky brown, spotted with dull ochreous along costa and 

 termen.
