Dyar, List of North American Lepidoptera, p. 568. 



Head rough haired. Labial palpi long-, curved and ascending, 

 second joint with dense hair brush beneath, terminal joint long and 

 pointed. Maxillary palpi curved, drooping. Antennae one half to 

 two-thirds of wing length, ciliated in the male; basal joint with pec- 

 ten. Forewings with 12 veins; vein 1/ furcate at base. Hindwings 

 as wide as the forewings, elongate oval, cilia one half. All veins 

 present. Hind tibiae rough haired. 



This genus, which, according to Mr. Merrick, is nearly cosmopo- 

 litan, contains only a small number of species, some of which, how- 

 ever, are among the largest of the Tineidae with polyarticulate max- 

 illary palpi. The same author* describes the latter organs as short 

 and porrected, this I could not verify in any of ours nor in the 

 European species, which I have seen ; they are rather long, filiform 

 and curved downward, except in coloradella, where they are short, 

 thickened with scales and partially plicate. 



The species may be arranged in two natural groups as follows:
