LIOPTILUS. 47 



running along the upper edge of the second lobe 

 to its apex ; the lower one coming also from the 

 base and attaining the dorsal margin below the 

 base of the cleft. The costa pale ; the cilia 

 tinged with grey. 



Hind wings and fringes pale cinereous. 



Abdomen and legs slightly yellowish white. 



Underside uniformly pale cinereous, except the costa 

 and the fringes of the anterior lobe within the 

 fissure, which are whitish. 



Expanse 25 millims. 



I obtained two specimens early in May on Rouge 

 River, Southern Oregon. 



It is nearly allied to L. modestus, apparently to be 

 distinguished by its much larger size, by the whiter 

 ground-colour of the head and fore wings, and espe- 

 cially by its whitish costal margin and decidedly 

 shorter palpi. 



Mr. Walker's description of this species is scarcely 

 sufficient to distinguish it from its allies ; but a care- 

 ful comparison of my Oregonian examples with the 

 typical specimen in the British Museum makes it 

 impossible to consider them distinct. St. Domingo 

 is given as the locality from which the type was 

 obtained ; and it is certainly surprising that the same 

 species should occur in such widely different degrees 

 of latitude.
