TWO NEW SPECIES OF MEXICAN TINEIDS. 



BY AUGUST BUSCK. 



Ethmia mulleri, new species. 



Labial palpi and face blackish fuscous. Tongue ochre-yellow. An- 

 tennae blackish, basally with white annulations. Head white. Thorax 

 white with posterior tip black. Fore wings pure white with a costal 

 longitudinal streak from base to apex dark slate-colored ; at the extreme- 

 base of the dorsal edge is a deep black round dot and on the wing are 

 six similar black round dots, placed in pairs in two longitudinal rows 

 of three dots each: the first pair at basal fourth, with the upper dot 

 slightly nearer the base of the wing than the lower dot ; one pair on 

 the middle of the cell and one pair just beyond the end of the cell: in 

 both these latter pairs the upper dot is placed obliquely to and further 

 out than the lower. Along the terminal edge is a row of six black- 

 marginal dots. Cilia white. Hindwings light slate-colored with white 

 cilia and in the male with a strong yellow hair pencil at the base of the 

 costa. Abdomen dark fuscous with second joint above and terminal 

 joint ocher-yellow. Legs dark slate-colored with yellow tarsal annu- 

 lations. 



Alar expanse, 21-22 mm. 



Habitat Tehuacan, Mexico, July, September (R. M tiller). 



Type No. 12810, U. S. National Museum. Cotype in 

 Museum Walsingham. 



A clear-cut species, nearest in color and size to the Euro- 

 pean Ethmia sexpimctella but with the six spots placed dif- 

 ferently and further distinguished by the male costal tuft. 

 In the American series it comes next to Ethmia lia^cucUa 

 Chambers. 



It gives me pleasure to name this pretty species in honor 

 of the collector, Mr. R. Miiller, who has added very many 

 Mexican Lepidoptera to our collections. 



Stenoma loxotoma, new species. 



Labial palpi long, evenly covered, reaching above the vertex: second 

 joint thickened with appressed scales, slightly ruffled anteriorly to- 

 wards apex; ocher-yellow at base, blackish above, whitish gray at the 

 tip; terminal joint smooth pointed, whitish gray shaded to blackis'i 

 fuscous anteriorly. Antenna?, male, shortly ciliated (1) gray with in- 

 distinct darker annulations; basal joint thickened with scales. Face 

 whitish. Top of head tufted, the long scales from each side meeting in 

 the middle; whitish gray on the sides, darker gray at tip of tuft.
