Head smooth, side tufts slightly raised; tongue developed; an- 

 tenna ciliated; basal segment without pecten. Labial palpus long, 

 recurved, smooth or slightly roughened ; terminal segment shorter or 

 as long as second segment. 



Fore wing elongate, apex pointed ; 12 veins ; 2 from well before angle ; 

 3 and 4 approximate; 7 and 8 stalked, both to costa, 11 from before 

 middle. 



Hind wing narrower than fore wing, costa gently arched, 8 veins ; 

 3 and 4 connate, 5 nearer to 4 than to 6 ; 6 and 7 subparallel. 



Male genitalia. — Harpe ample. Anellus with lateral extensions. 

 Gnathos a broad, unspined band. Socii absent. Uncus well 

 developed. 



Femah genitalia. — Genital plate strongly sclerotized ; ductus bursae 

 wholly membranous or slightly sclerotized for part of its length; 

 signum present or absent.^" 



Remarks. — Busck ^^ recognized five species in this genus (but placed 

 them under the name EpicalUma) . Of these I have synonymized one, 

 dimidiella.) with quadrimaculella and have placed coloradella in the 

 Ethmiidae. The genus Ethmia., as it now stands, is not a homogeneous 

 assemblage of species and will accommodate coloradella. The proper 

 generic placement of this species must await a revision of the Ethmi- 

 idae, and for that reason no further treatment of coloradella is given 

 in this paper. In 1912 ^^ Busck added lucidella; Meyrick described 

 antidectis in 1914 ^^ and rostrigera in 1918.^* The first, lucidella.^ 

 belongs in SchiffermulleHa., antidectis is referable to TricloneUa in 

 the family Cosmopterygidae, and rostrigera is a synonym of coloradella 

 (new synonymy). In 1923^^ Braun added amplicincta which is a 

 synonym of editheUa. I have retained the generic name Eficallima 

 for argenticinctella (Clemens) and have associated the European 

 formoseUa (Schifferm tiller) with it. The latter has become estab- 

 lished in the United States in recent years. This leaves three North 

 American species referable to the genus Schi-ffermulleria. 



^ There is only a single female each of editheUa and lucidella available for study. The 

 bursa copulatrix of editheUa is missing, and that of lucidella, although partly obscured, 

 appears to lack a signum.
