68 AMERICAN LEPIDOPTERA. 



veins free. Hindwings as wide as the forewings, costa 

 scarcely retuse, rather obtusely pointed; cilia scarcely 1; 

 eight veins, 3 + 4 stemmed, 5 out of stem of 3 +4 near its 

 base. Brush of posterior tibiae not strongly marked. 



Differs from Holcocera in the presence of scale ridge and 

 tuft on the forewings, and the front fringed each side with 

 hair-like scales, two characters not observed in any other 

 genus of the family known to me. The type is a female. 

 The male in all probability, when discovered, will have the 

 antennas excised above the basal joint. This latter character, 

 together with the scale ridges of the forewing, would show a 

 certain analogy to certain Phycitid genera. One species only. 



1. E. auoimxlella n. sp. (Plate IV, fig. 40, 40a.)— Palpi light 

 gray, speckled with brown, especially the second joint externally. 

 Head smooth scaled, except posterior edge of occiput, which is some- 

 what rough haired, scales of front and vertex about equally mixed 

 brown and pale gray, sides of front fringed with closeset pecten-like 

 hairs of a grayish color. Antennas fuscous, basal joint nearly twice as 

 long as wide, pecten long, gray. Thorax fuscous-brown, intermixed 

 with gray scales posteriorly. Ground color of forewings whitish, 

 sprinkled with dark brown scales ; extreme base of costa and a trans- 

 verse dorsal spot very close to the base, blackish brown, at less than 

 one-sixth the wing length is a strongly marked transverse ridge of dark 

 brown scales with an aeneous lustre, at about one-third is an oblique 

 costal streak, slightly convex outwardly, which reaches the fold, where 

 it joins a less distinct dorsal spot, just above the fold and on the 

 streak is a fuft of dark brown scales with aeneous lustre ; beyond the 

 fascia or streak the dark dusting is more pronounced, especially in the 

 costal portion, two dark spots at end of cell, the lower one of these is a 

 trifle nearer the base. Two obscure longitudinal streaks in median 

 space, and an acutely angulated line in apical portion of wing, a row 

 of irregular dots along base of cilia. Cilia gray, with about three pale 

 lines, one near the middle, one near and the other along the outer mar- 

 gin. Underside grayish-fuscous. Hindwings gray, dusted with fus- 

 cous ; cilia gray, with an obscure darker line before the middle. Under- 

 side pale grayish-fuscous. Abdomen grayish-brown, segments edged 

 with white scales. Underside of body pale yellowish-white with some 

 lustre. Ovipositor not exerted. Legs silvery white, the anterior rather 

 densely dusted with fuscous, especially within, tibiae at both ends and 

 median fascia white, hind legs less densely dusted, except tarsi, leav- 

 ing the apices of joints paler. Expanse 19.0 mm., 0.76 inch. 



Hab. — Arizona (Pinal Mt.). 



The type, a female, in the Nat. Mus. Coll. This peculiar 

 s pecies could not be mistaken for any other of this family.
