Palpi rather stout, ascending, passing a little beyond tlie front; third joint 

 rather long, conical. Autennge ochreous, ashen above, with long, delicate, 

 fine, close-set, black pectinations. Body pale cinereous, with an almost 

 iniperceptil)le ochreous tinge. Fore wings with a basal, slightly-curved, dark, 

 diffuse line, which is especially marked on the veins; discal dot distinct, but 

 diti'use, rather larger than in T. Jhcellaria; an outer, not very oblique, slightly 

 sinuate, dusky line, sometimes angulated on the first median venule in both 

 wings; it is thickened on the venules, curving inward a little toward the 

 base ; the wings are rather thickly flaked with smoky strigse, especially on 

 the costa and outer edge. Hind wings without any discal dot ; the single 

 line a little curved, not reaching to the costa; wings very transparent at the 

 base. Beneath, whitish, very transparent ; the lines faintly apjiear; no discal 

 dot; costa tinged slightly with ochreous. Hind wings scarcely angulated, 

 the angle being almost obsolete. 



Length of body, i, 0.50; of fore wing, i, 0.70-0.73, 9, 0.75; expanse 

 of wings, 1.50 inches.

This is a very variable species, in rubbed examples being unusuall}' pale 

 transparent ashen, but dusky in fresh specimens. The lines are arranged 

 much as in IL. Jiscelluria, but where the wings are slightly rubbed they arc 

 represented by a series of punctures on the venules. The unusually long, 

 filiform, closely-set pectinations of the antenna;, and the granite-gray wings, 

 with dusky lines, not tinged with ochreous, will distinguish it from the other 

 species. It varies greatly, the lines in one female being twice as far apart 

 as in another, and the outer line in some being almost straight, in others a 

 little bent. If I had had Mr. Grote's types alone of male E. hibuluria and 

 female jiellucidaria, I should have regarded them as distinct; but, with the 

 addition of other specimens of both sexes, I have felt compelled to unite them, 

 as the species seems to be as variable as in T. Jiscellaria. One Kentucky 

 female expands only 1.20 inches. It is represented on plate 12, fig. 5; but 

 the artist has not represented the inner line on the fore wings.
