The typical form of this species has the upper side dark-gray 

 and the under side darker green than the other species of the genus. 

 Both wings, beneath, are crossed by bands of white composed of fused 

 or nearly fused dots on the primaries, while the dots on the secondaries 

 are, in the main, actually fused so they no longer appear as dots. This 

 band is quite wide and, at least on the secondaries, inwardly lined 

 by a distinct black line. The fringes are practically pure white out- 

 wardly. 



The typical form is represented in the Barnes Collection from the 

 region around Denver, Colorado, in April. 



Callophrys sheridani race neoperplexa nov. 



1919 (1922), Draudt, Seitz Macrolepid. World, Exotica part 231, Fauna 

 Amer. part 84, p. 763, (prob. extreme of this form in err. as affinis), 

 Thecla (Callophrys). 

 This is the Utah race of C. sheridani. On the upper side the ground color 

 is a slightly paler gray and the fringes do not show pure white outwardly. Be- 

 neath the difference is more conspicuous in that the band is reduced to a di- 

 agonal row of dots or entirely lost on the primaries while the broad band on 

 the secondaries has been reduced to a faint line which tends to become broken 

 and obsolescent. 



Males of this form might easily be confused with small and poorly 

 marked males of C. dumetorum which probably gives rise to Utah 

 records for that species. 



One specimen from Cloudcroft, N. IMex., is somewhat interme- 

 diate to the typical race but better referred here.
