Hah. North America, Arizona 1 . — Mexico, Northern Sonora (H. K. Morrison), near 

 Durango city [Becker). 



We have several of Morrison's specimens from Fort Grant, Arizona, and the frontier 

 between that State and Sonora, as well as one from near Durango. These all differ 

 from S. aurocapilla in having longer palpi, the colour of which is pure white beneath, 

 and in the primaries having two hyaline spots in the male and three in the female 

 near the apex. 



The male of S. aurocapilla has no such spots, though the female possesses three very 

 small ones. 



The species was described by Mr. W. H. Edwards in 1882 from Morrison's specimens. 



The male genitalia have a long slender tegumen : the harpes are cleft into two lobes ; 

 the upper one simply rounded with a nearly straight outer margin, and beset on the 

 edge with short bristles ; the lower lobe slightly overlaps the upper one at the base, has 

 a rounded end and a depression on the dorsal edge, the outer margin carries bristles, 

 and the sides are hairy. (See Tab. LXXXIX. fig. 8.)
