obtuse apex, and Lhc much-rounded liiud wings, as well as the long fringe on 



hot li pairs. In the European E. herbaria, the subcostal cell is closed, but in 



several specimens of our E. chloroleucaria il is open. The legs differ greatly 



in the length of the tarsi in (lie differenl species, bul the shape of the wings 



is very constant. 



Synopsis of the Species. 



Lines narrow, very distinct ; outer lint' curved ; palpi short E. tteilleraria. 



Lines broad, distinct; outer line straight : palpi rather long K. chloroleucaria.

t! 3 and 1 9. — Pea-green. Head and antennae whitish-ochreous; fronl 

 deep green. Palpi and legs pale ochreous. Fore wings pale ochreous on the 

 eosta; two parallel, very distinct, whitish-ochreous lines, both curved on the 

 costal region, much alike., and nearly parallel and both a little wavy. The 

 outer line continued on to the hind wing, and rather suddenly bent a 

 little outward in the middle of the wing, the similar line in cliloroleucaria 

 being straight. The fringe on both wings is paler than the wings. Beneath 

 greenish, washed slightly with ochreous; costa of fore wings ochreous. 



Length of body, <?, 0.27, 9. 0.33; of fore winy, <?, 30, 9. 0.40; 

 expanse of wings, 0.60—0.84 inch. 



Waco, Texas, August 8-21 (Belfrage, Mus. Peab. Acad. Sc). 



This exquisite species differs from E. chloroleucaria, being less strigated 

 with white, and in the head being green in front instead of reddish; in the 

 outer line being curved like the inner on the costal region instead of straight; 

 and in the single line on the hind wings being suddenly bent in the middle. 

 It is more nearly allied to the European herbaria than cliloroleucaria. The 

 hind legs are as in chloroleucaria, however, with a large brush of hairs; hind 

 tarsi half as long as the tibiae.
