Metopleura potosi, new species. 



Labial palpi light straw-colored, speckled with fuscous. Antennae light 

 fuscous. Face, head, and throax light ochreous. Fore wings ochreous, 

 longitudinally streaked along the vein, with lighter whitish ochreous. 

 From near the base of costa runs an outwardly oblique blackish fuscous 

 streak across half the wing and at apical fourth on the dorsal side is found 

 a poorly denned blackish streak, parallel with termen; both of these mark- 

 ings are easily rubbed off and the majority of the long series before me shows 

 only traces of them. There is a series of poorly denned dark marginal 

 dots around apical and terminal edge. Cilia ocherous mixed with dark 

 fuscous. Hind wings shining, dark fuscous with a light ochreous marginal 

 line on the base of the cilia. Abdomen ochreous fuscous. Legs ochreous 

 speckled with fuscous. 



Alar expanse, 30 to 36 mm. 



Habitat: Cerritos, San Luis Potosi, Mexico, August. R. 

 Miiller, collector. 



Type: No. 14523, U. S. National Museum.

Ethmia proximella, new species. 



Labial palpi white; second joint dusted with black exteriorly. Face 

 and head white. Thorax white with four bluish-black dashes, two ante- 

 riorly, two posteriorly. Fore wings white with a broad black costal edging ; 

 widest on the middle of the wing; the line between this black costal part 

 and the white dorsal part of the wing is zigzagged and irregular. On 

 the white dorsal part of the wing are a number of round bluish-black 

 dots, of which one is near base, one on the middle of the cell and one on the 

 fold obliquely below; then come three dots in an oblique row, the first 

 on the middle of dorsum, the last on the lower edge of the cell; after these 

 there is further out another oblique row of three equidistant dots and 

 parallel with the terminal edge is an irregular double row of less clearly 

 defined dots. The extreme terminal edge golden yellow. Cilia white 

 with dusky tips. Hind wings smoky white, in the male with a large yel- 

 lowish costal tuft. Abdomen dark fuscous with yellow tip. Legs ochreous 

 white; tarsi with strong black annulations. 



Alar expanses, 17 to 20 mm. 



Habitat: Tehuacan, Mexico. R. Miiller, collector. 



Type: No. 14524, U. S. National Museum. 



Cotype in British Museum. 



This species was sent me by Mr. Miiller as Ethmia 

 mulleri Busck, which it resembles in size and ornamentation; 

 it is, however, easily distinguished by the more numerous 

 black dots on the fore wings (in mttUeri there are only six in 

 three pairs), by the lack of the well-defined terminal series of 

 black dots, and by the presence of the golden terminal line.
