the length of forewings, rather thick. Forewings elongate, without 

 scale tufts; 11 veins, all free ; 11 arises very near the base, l 6 sim- 

 ple. Hindwings lanceolate, costa retuse from just before the middle 

 to apex ; 8 veins ; cell open between 3 and the common stem of 4, 

 5 and 6. Cilia over 2. Hind tibiae fringed with long hairs. 



A very distinct genus, closely allied to Homosetia, from which it 

 differs in venation of hindwings, the open cell of the latter likewise 

 distinguishes it from the other allied genera. One species. 



Li. miriamella. n. sp. — PI. Ill, fig. 8. — Labial palpi dark fuscous brown 

 externally, second joint and apex of third whitish within. Maxillary palpi 

 creamy white. Face yellowish white, vertex and thorax blackish brown, hairs 

 of head somewhat tufted each side. Ground color of forewings white, overlaid 

 with a rich dark brown, the latter condensed in the costal half of wing and in the 

 apical part, except an irregular, rhomboidal costal spot just beyond the middle; 

 in the basal part of dorsal half of wing, the dark scaling is less dense, two well- 

 marked dashes on the fold and another obliquely above the outer plical dash, 

 immediately behind the latter, at the end of cell is a rather pure white spot and 

 a similar one between the two dashes on the fold. Cilia yellowish white, with a 

 somewhat irregular dividing line, and five or six dark brown streaks extending 

 from the dark apical part of wing, one of these expands into a distinct round 

 spot in the apical portion; aside from these are numerous blackish, scattered 

 scales. Hindwings fuscous with a faint metallic lustre, cilia concolorous. Abdo- 

 men fuscous above, tinged with silvery gray, underside of body silver gray. 

 Legs grayish, anterior and middle, more or less fuscous externally ; tarsal joints 

 fuscous above. 



Exp. 9.5-13.0 mm. ; 0.38-0.52 inch. 



Hab. — Pennsylvania (Hazleton ; Mauch Chunk) ; Maryland 

 ( PI u miner's Island). 



A number of specimens were taken by my daughters on the 

 trunk of an old cherry tree in June and July, and after one of 

 which it gives me pleasure to name this interesting addition to our 

 fauna.
