Plate 56, Figures ."i, G 



This conspicuous species is common in the South and is recorded 

 from various places in North Carolina and Virginia, and even as 

 far north as Cape May, N. J. 



The wings above are brilliant metallic bluish green broadly mar- 

 gined with brown, and below are brown with a large group of bril- 

 liant metallic spots of various colors at the anal angle.

Plate 25, Figures 5, 6 



This very rare little butterfly is quite as likely to turn up in the 

 District as in some of the other places where it has been found. 



The color above is brown glossed wdth blue, and below pale fawn 

 with a curved band of pale red spots along the inner edge of the 

 outer fourth of the wings, and on the hind wings a second more 

 irregular band across the middle. 



INCISALIA POLIOS Cook and Watson 



This species occurs from north-central Alaska (Fort Yukon) to 

 Lake Athabasca, New Hampshire, and Nova Scotia, and southward 

 to California, Colorado, and New Jersey. It is to be looked for in 

 (he District, flying very early in spring witli /. augusthius. 



In general /. polios resembles /. augustinus, but the underside of 

 the fore wing has a conspicuous, though narrow^, light-gray border, 

 and the underside of the hind wing is heavily washed with grayish 

 white scales in the outer half. 



Messrs. Cook and Watson have suggested that the specimens 

 described by Mr. Scudder as representing a varietal form of /. irus 

 having the outer margin of the fore wings narroAvly hoary from 

 Norway, Me., and Needham and Walpole, Mass., are really repre- 

 sentatives of this species. 



INCISALIA MOSSI (Henry Edwards) 



This western species has been recorded from the East, though not 

 from the vicinity of the District.
