Sierras ; the southern race, bernardino B. & McD. may be readily rec- 

 ognized by its smaller size and whiter underside. 



For the form with cnoptes-like genitalia which we have been erro- 

 neously calling glaucon and which we figured in our Contributions, 

 PI. XI, Figs. 2, 5, a new name will be needed and we propose using 

 ancilla; the form is so similar to the true glaucon in maculation as to 

 render our misidentification almost excusable ; we can point to no obvi- 

 ous specific differences although there is a tendency, especially in the 

 9 , towards a rather rougher squammation on the underside and a 

 thickening of the black basal fringe line ; the $ 's show only traces 

 of fulvous on upper side of secondaries ; we regard it as a race of 

 cnoptes from which it may be distinguished by the continuous fulvous 

 band on the underside of secondaries which in typical enoptcs is always 

 broken into small spots ; the black spots are also heavier. Our type 

 specimens are a series of 6 3,4 2 from Eureka, Utah (July 1-7) 

 two of which are figured as glaucon on the above mentioned plate; we 

 also possess numerous specimens from other localities in Utah and 

 Colorado. 



We cannot agree with Mr. R. C. Williams that glaucon Edw. is 

 the same species as our spaldingi (Ent. News XXIX, 101) ; Edwards 

 in his description of the underside of the secondaries of glaucon dis- 

 tinctly states that a broad orange stripe occupies the space between the 

 two submarginal rows of spots ; this does not at all apply to spal- 

 dingi in which the red area is reduced to crescent-shaped spots and the 

 inner row of spots is almost lacking; the median row of spots is also 

 not pronounced enough to fit in well with Edwards' diagnosis.
