AMERICAN LEPIDOPTERA. 1 3 



smooth scaled, occiput rough haired. Antennae slender, simple, 

 nearly as long as the forewing, first joint without pecten. Fore- 

 wings rather wide, all veins present, veins 5 and 6 out of one point, 

 7 out of 8 ; on accessory cell l b furcate. Hindwings ovate, as wide 

 or wider than forewings, with 8 veins; 5 and 6 stemmed, I 6 nar- 

 rowly furcate at base. 



In general appearance the species resemble those of the first 

 group of Amydria. 



The three species are distinguished as follows: 



Ground color of forewing ochreous. 



Base of forewing not entirely purplish brown ; wings less elongate. 



simulella. 

 Base of forewings purplish brown ; wings more elongate. 



Ehrhoruella. 

 ' i round color of forewing bony-white erucilerella. 



I*, simulella. n. sp. — Sordid ochreous. Labial palpi, except second joint 

 within, dusted with fuscous. Face with a faint pearly lustre. Antennae pale 

 fuscous above. Thorax anteriorly fuscous brown. Forewings moderately wide, 

 obtusely pointed at apex, costa equally curved from base to apex, thinly dusted 

 and spotted with purplish fuscous brown, base of costa and dorsal margin dark 

 brown, a row of small dots on basal half of costa, beyond these are three larger 

 spots, the middle of which is the smaller, in the apical part are three or four spots 

 extending as lines into the costal cilia; a longitudinal dash at one-third and 

 another at two-thirds of the fold, the latter being the most marked. A large 

 irregular blotch at end of cell, and before it at two-fifths another though some- 

 what smaller spot on the disk ; two short, parallel dashes in apical part of wing ; 

 along base of dorsal cilia is a row of semi-confluent dots and some similar though 

 less distinct spots along the free dorsal margin. Cilia concolorous, speckled with 

 fuscous scales. Hindwings obtusely pointed, ochreous fuscous, cilia concolorous, 

 with indistinct subbasal line. Underside of wings pale, grayish fuscous. Abdo- 

 men above ochreous fuscous, underside of body and legs dusted with fuscous; 

 tarsal joints pale at apex. 



Exp. 18.0-25.0 mm. ; 0.82-1.0 inch. 



Hab. — California (Folsom ; Los Angeles). 

 Two specimens before me. 



P. Ehrlioruella n. sp. — Smaller than simulella, wings narrower, more 

 acutely pointed at the apex, especially the hindwings. Ochreous; palpi more 

 deeply fuscous externally. Vertex ochreous fuscous. Antenna- fuscous brown 

 above. Thorax dotted with fuscous. Forewings elongate, conspicuously marked 

 with purplish brown as follows : Base entirely, except a minute dot at extreme 

 base of fold, five or six irregular transverse spots on basal half of costa ; beyond 

 these three larger rounded spots, of which the middle one is smaller, four costal 

 spots in the apical part extending as oblique lines into the cilia; on and immedi- 

 ately above the fold are three quadrate, well-defined spots, separated by the
