Head smooth, side tufts somewhat spreading. Tongue developed 

 but short. Antenna shortly ciliated in male, simple in female ; basal 

 segment without pecten. Labial palpus moderatel}'^ long, curved ; sec- 

 ond segment with appressed scales which protrude at apex ; terminal 

 segment much shorter than second, slender, acute. 



Fore wing ample, elongate ; 12 veins ; 2 and 3 approximate, connate 

 or stalked, 7 and 8 stalked, 7 to costa or apex, 11 from well before 

 middle. 



Hind wing as broad as fore wing, ovate; 8 veins; 3 and 4 closely 

 approximate or connate. 



31 ale genitalia. — Harpe elongate; sacculus frequently produced. 

 Anellus with lateral processes that are sometimes reduced. Transtilla 

 membranous; lateral lobes usually slender, digitate but greatly re- 

 duced. Gnathos a spined, oval knob. Socii mainly indicated by hairs. 



Female genitalia. — Ductus bursae membranous or partially sclero- 

 tized ; signum present. 



Remarks. — Meyrick ^^ separates Epigraphia from Semloscopis on the 

 condition of veins 2 and 3 of the fore wing (stalked or separate), yet 

 he ignores this same character in the case of Agonopterix and Depres- 

 saria except to use it to divide Depressaria into two sections. In Semio- 

 scopis veins 2 and 3 are much more unstable than in Agonopterix and 

 Depressaria., indicating that Semioscopis is in a state of flux and not
