PLATYPTILUS. 19 



margine dorsali albidis, in margine apicalifuscis 

 at bo terminates. 



Alls et tibiis posticis cinereis, ciliis et pedibus paulo 

 pallidioribus. 



Head and palpi cinereous; antennae slightly dotted 

 above. 



Fore wings very narrow, cinereous, with a slight 

 ochreous tinge towards the dorsal margin. The 

 costa sprinkled and shaded with fuscous, the 

 fuscous shade widening towards the fissure, form- 

 ing an elongate but indistinct triangular costal 

 blotch. The apical portion of the wing more or 

 less shaded with fuscous, and a fuscous line along 

 the base of the cilia on the apical margin, which 

 are whitish at their points. The cilia within the 

 fissure and those along the dorsal margin before 

 the anal angle white, the latter containing a few 

 dark scales. 



Hind wings cinereous; the cilia slightly paler, espe- 

 cially along their bases. 



Posterior legs cinereous ; the feet slightly paler. 

 Expanse 22 millims. 



This species, of which I took two specimens, in 

 fair, but not very good, condition, on the 4th of June, 

 1871, near Mendocino, in California, has narrow fore 

 wings, and is plain and inconspicuous ; the posterior 

 or anal angle of the fore wings is very well defined,
