Godart's remark, suggesting that the difference between comyntas 

 and amyntas (argiades) is merely the tiresias character of having golden 

 metallic spots on the underside of the hindwings, near the anal angle, 

 is to be noted. Scudder gives (Butts, of New Engl., ii., pp. 911 et seq.) 

 not only the lengthy details already quoted (supra) of its life-history, 

 distribution, etc., but also a very full description of both sexes, too 

 long, however, to be transcribed here, but to which reference certainly 

 should be made. He also adds the following interesting details of 

 measurement :

Few other details are obtainable, and, as we have before noted, the 

 further study of the species in America is eminently desirable. 

 Oberthur, who has this form from Massachusetts, Texas, California, 

 and British Honduras, says (in litt.) that it is " smaller than amyntula, 

 although the blackish marginal border is wider ; there is a trace of 

 reddish -orange spots on the upperside of the hindwings, near the little 

 tail ; the ? is black, suffused slightly with blue on the upperside ; on 

 the underside, the black mark, surmounted with reddish-orange, carries 

 a shiny metallic dot. 2 $ s, 2 ? s, Boisduval coll. ; 4 $ s, 2 $ s. Guenee

 differe en ce que le male n'a pas de lunules fauves en dessus, en ce que le dessous 

 des deux sexes est plus blanc, avec les points plus petits, et en fin, eu ce qu'il n'y a

Oberthur, who possesses Boisduval's type of this insect, notes it as 

 a " $ from California, of large size, on the upperside of a blue, 

 slightly lilac, tint, the black marginal border very wide ; the underside 

 white, slightly grey, with the ordinary black points small, and with 

 two yellow-orange marks, one of them large, near the tiny tail, and 

 the other, less accentuated, by the side of the larger one." Oberthur 

 further notes that he possesses the same form from Arizona, California, 

 and Mexico. This appears to be not only the Pacific States' form of the 

 species but also the Western Canadian form, according to the Ameri-
