One male, Dripping Spring, Organ Mts., New Mexico (Cockerell). 

 U. S. Nat. Mus., type No. 6622. 



The ornamentation is much as in hagenella, but more confused. 

 It also much resembles^, mannorea, but the genitalia differ markedly. 

 The anal plate ends in a single spine, curved downward ; side pieces 

 strap-shaped, curved inward and a little upward, all pale testaceous. 



Ethmia marmorea ]VaIs. 



In the male genitalia the anal plate is short without central spine, 

 but a long, curved, hair-shaped one at each angle. The side pieces 

 are short, curved inward with a strongly chitinized, finely dentate, 

 black, angulated inner edge that is characteristic and conspicuous. 

 None of the other species of the genus that I have seen have any- 

 thing like this structure.

Ethmia semilugens Zell. 



Ancsycliia multipiinctella Chami;. 



Psecadia seiniopaca Grote. 



Psecadia pliimbeella Beut. 



Grote's description of semiofaca tallies exactly with specimens of 

 semilugens. Beutenmiiller's type o{ plionbeclla is before me and is 

 only a soiled specimen of normal semilugens ; the plumbeous color is 

 obviously not natural. In the male the anal plate is furcate, the 

 spines separate, parallel, curved down, rather remote. Side pieces 

 strap-shaped, curved inward and upturned, all pale testaceous.

Ethmia trifurcella Chanih. 



I have not seen this species, but Mr. August Busck has made notes 

 on the type which he has kindly loaned me. It is very much like the 

 following, but with the color on lower half of wing pure white. 



Ethmia semiombra, sp. nov. 



Head and thorax pale gray, palpi with a black ring on second joint and two on 

 the last joint ; a brown dash on posterior verte.v of head. Fore wing with the costal 

 part brown, the internal part pale gray, dusted with brownish scales. Limiting line 

 sharp, free of dusting scales, the brown thrice excavated, with a dot in the second and 

 third excavations, that in the second small and before the middle, that in the third
