142 BULI^ETIN 123, UNITED STATES NATIOI^AL, MUSEUM. 



the same stout, broad, almost triangular aedoeagus, the same well 

 separated socii, the same hood like, round, reduced uncus and the same 

 squarish chitinization of the subanal plate of the gnathos; in color 

 marking they agree in all having a blue black second antennal joint, 

 a black terminal joint of palpus and a round black spot on the outer 

 side of second joint of palpus. They vary greatly in the ground 

 color and pattern of fore wings and in size and shape of the harpes. 



I have split the complex and grouped the forms under district 

 names upon the same logic that prompted the lumpings under 

 strenuana^ namely to prevent confusion. The strenmana and numero- 

 sana groups are very close but have constant and obvious characters 

 to separate them. Now with the strervuana forms we know they are 

 all one species for all their varieties have been produced from a single 

 rearing from a single locality (District of Columbia). With the 

 numerosana complex on the other hand we have only a strong sus- 

 picion of specific identity. They have not been reared. When they 

 are I expect we shall find them all one species. Until then however, 

 I think it best to keep the different forms under separate names. 

 They can always be lumped and in the mean time no harm is done by 

 the synonomy.

(Fig. 261.) 



Like nwmerosana except: Head and thorax more whitish. Fore 

 wing very pale gray ; costa of the gray ground color finely and evenly 

 strigulated from base to apex with fuscous; an outwardly angulate 

 basal patch indicated only by a narrow fascia of blackish fuscous 

 scales on its outer margin; on dorsum bordering the inner margin 

 of ocellus a narrow band of blackish fuscous scaling; joining this a 

 faint, narrow, more or less continuous line of blackish fuscous scales 

 from middle of costa ; a distinct blackish fuscous spot at apex ; above 

 and at outer margin of white ocellar spot some streaking of blackish 

 scales ; cilia white dusted with pale fuscous giving an even light gray 

 color to the fringe.
