(very short, Tineola). Maxillary palpi well developed, polyarticu- 

 late, filiform, generally 6 jointed and plicate; more rarely {Xyles- 

 thia, Abacobia), 3-4 jointed and porrect; entirely rudimentary in 

 Tineola and Tenaga. Labial palpi variable, generally porrect and 

 somewhat drooping, with spreading apical and some lateral setae; 

 more rarely (Scardia, Xylesthia, Abacobia) , ascending and the second 

 joint with a dense or loose brush of stiff hairs beneath. Antennae 

 filiform, variable in length, generally over one-half; rarely (Tripto- 

 dema) as long as the forewing, glabrous, or finely pubescent in the 

 male, rarely (Phryganeopsis) ciliated in both sexes, or in the male 

 only ( Ineurvaria, Cyone) ; first joint not dilated into an eye-cap, 

 rarely with pecten. Wings equally developed in both sexes. Fore- 

 wings varying from oval to elongate-lanceolate, with 12 or 11 veins, 

 vein 7 to costa more rarely to apex. Hindwings oval to lineo- 

 lanceolate, 7 or 8 veins; vein l 6 simple (shortly furcate in Breck- 

 enridgid). Posterior tibia? generally rough haired. 



This subfamily contains some of the largest as well as some of the 

 very small species of the superfamily Tineina. 



The genera may be tabulated as follows : 



Labial palpi ascending; second joint with stiff hair brush beneath. 



Maxillary palpi plicate ; hair brush compact (1 ) S«-si r<l i:i . 



Maxillary palpi porrect, uot plicate; hair brush loose, spreading. 



Forewings with scale tufts (2) Xylesthia. 



Forewings without scale tufts (3) Abacobia. 



Labial palpi porrect or drooping, more rarely ascending; second joint without 

 brush beneath, generally with spreading apical bristles. 

 Vein 16 of forewings furcate at base. 



Forewings with vitreous spof, veins 3 and 4 stalked (4) Monopis. 



Forewings without vitreous spot, veins 3 and 4 free. 



Forewings with veins 10, 11 and 12 concurrent (5) Trichophaga. 



Forewings with these veins normal. 



Forewings with 12 veins, free, or 7 and 8 stalked 

 Labial palpi long, porrect, entirely rough haired. 



(6) Phrygaueopsis. 

 Labial palpi moderate, terminal joint not rough haired. 



Antenna; of male ciliated (7) Incurvaria. 



Antennae of male simple. 



Maxillary palpi developed, plicate (12) Tinea. 



Maxillary palpi obsolete (14) Tineola. 



Forewings with 11 veins. 

 Veins free. 



Antennae ciliated (8) Graya. 



Antenna; simple ( 10) Breckenridgia. 



Veins not all free.
