The entire wings segregate our single species of Agdistis so con- 

 spicnously that no other characters are needed for its identification. 

 The neuration differs in several particulars from that of the genotype. 



1. Agdistis Americana n. sp. PI. XLII, fig. 20. PI. Lit, fig. 16. 



iAgdistis adactyla Dyar (Not Hbn.), Proc. Ent. Soc. Wash. X, 60, 1908. 

 Barnes & McDiinnough, Check List 151, 1917. 



Vestiture of head and body of whitish and brownish gray scales, under 

 parts overlaid with white. Abdomen with paired dorsal dots on posterior 

 margins of segments. Legs concolorous, more or less whitish on one side ; 

 spurs short. 



Primaries with a gray brown, thinly scaled, subtriangular area beginning 

 at basal third of cell and extending to outer margin with limits of cell con- 

 tinued in a sharp line equidistant from inner and costal margins respectively 

 as its boundaries. Remainder of wing with mixed whitish and fuscous scales. 

 There is usually a fuscous spot at apex of thinly scaled triangle, two dots on 

 its hind margin, and several spots in the apical portion of the costa. Fringes 

 grayish white with a dark median line. Secondaries and their fringes similar 

 to triangle, sometimes with a slight "pepper-and-salt" area on outer margin. 

 Fringes with a faint dark line. Expanse 24 mm. 



The male genitalia are abundantly distinct from those of the European 

 adactyla Hbn. 



Described from a long series from San Diego, Cal., taken by Messrs. W. 

 S. Wright and Geo. H. Field, in every month from March to August. The 

 types are as follows : 



Holoti-pe $ , allotype, and 8 paratypes S in coll. Barnes. 



Paratype i and paratype 9 U. S. N. M. No. 23486. 



S paratypes $ , coll. W. S. Wright. 



The greater part of our series is from the collection of W. D. 

 Kearfott, who recognized the distinctness of the species and labelled 

 a type series with the name which we now adopt. We have but one 

 specimen of adactyla, a male, which differs from the American species 

 in its more brownish color, more conspicuously white costal fringes 

 on the primaries and u'hite hind tarsi (four distal joints only). The 

 genitalia, as noted, are much different. 



The species has apparently not been reared.
