AMERICAN MICROLEPIDOPTEKA. Ill 



giving a subserrulate appearance * Veins 4 and 5 of fore wing are 

 short stemmed in pallidotindella, longer stemmed in Heidemannella. 

 The two species are thus distinguished. 



Basal space limited externally by a straight oblique line (PI. VII, fig. 8). 



pallidotinctella. 

 Basal space angulate externally (PI. VII, fig. 9) Heideinannella. 



E. pallidotinctella sp. n. (PI. VII, fig. R).— Thorax, head and eye-caps 

 tawny, tinged with pale fuscous, eye-caps, with darker fuscous scales; antennaj 

 pale fuscous, with indistinct paler annulations. Labial palpi fuscous, terminal 

 joint blackish, second and terminal joints more or less concealed by long, dark, 

 ochreous, bristly hairs of the first joint: joints less distinct in the female. Fore 

 wings moderately elongate; costa feebly convex; ground color pale yellowish; 

 costa dark brown, more marked toward the base, basal space paler than rest of 

 surface, very thinly dusted with pale brownish scales, an oblique dark brown 

 fascia from one-third of dorsal margin to two-fifth of costa, shar])ly defined and 

 straight towards the base, illdefined outwardly, beyond the fascia is a subtrian- 

 gular area, thinly dusted with brown, containing two well defined dots at end of 

 cell and an elongate spot on the fold immediately below ; towards the apex, this 

 space is limited by an irregular, dark fuscous line ; apical part more densely 

 dusted with dark fuscous scales, an aggregation of paler scales at extreme apex. 

 Cilia pale greyish -stramineous, with 4 or 5 irregular and indistinct, paler lines. 

 Hind wings greyish fuscous, cilia concolorous. Dorsal segments 1-2 of abdomen 

 seneo-fu.scous, remaining part dark fuscous. Under side of body and legs silvery 

 grey, tinged with luteous; anterior legs and out side of middle and hind legs 

 more or less fuscous, tarsal joints tipped with pale at the apex ; under side of 

 wings fuscous. 



Expanse 10. mm.. .40 inch. 



Hab. — Hazleton, Pa. 



Three specimens taken the latter part of July, each in a different 

 year. 



E. Heideinannella sp. n. (PI. VII, fig. 9). — Head and eye-caps dark och- 

 reous fuscous, with purple reflections; anterior part of thorax dark purplish fus- 

 cous, posterior part and abdomen above tawny fuscous. Antennae pale fuscous, 

 with indistinct darker annulations above. Labial palpi extremely small, fuscous, 

 terminal joint darker. Fore wings elongate, ochreous, with dark brown dusting; 

 costa dark fuscous, purplish towards the base; basal square limited externally 

 by an angulated line at one-third the wing length, the dorsal extremity of which 

 is a little nearer the base than the costal end, very thinly dusted with broYH 

 scales, rest of wing thickly dusted with dark brown scales; two dots at end of 

 cell and a short dash immediately below on the fold. Cilia grey, costal and 

 apical cilia dusted. with dark brown and pale scales. Hind wings silver grey, 

 cilia concolorous. Under side of body and legs ochreous, abdomen, fore legs, out 

 side of middle and hind legs brownish fuscous; tarsal joints tipped with pale at 



* Not much importance can be ascribed to this character, as it occurs in some 

 other species, and at times semi-laterally.
