The third species, glaucon Edw. or spaldingi B. & McD., 

 I received from Mr. B. N. Lehman near Eureka, Utah, at 7500 

 ft. elevation, twelve years ago, and while recognizing it as 

 unusual and genitalically distinct, I have been unable to con- 

 vince myself that it is not Mr. Edwards' species. It is this 

 form from Stockton, Utah, that Dr. Skinner had before him, 

 and determined as glaucon, and there are two Colorado in- 

 dividuals of this form in Dr. Holland's Edwards collection in 

 Pittsburgh. The species is found in a number of the col- 

 lector's localities in northern Utah. The type specimens prob- 

 ably were collected near Virginia City, Nevada, and they ap- 

 pear to be lost. Although this locality and the known Utah 

 range of the species are widely separated, the physiographical 

 conditions are similar, and the insect may have a wider range 

 than now appears, especially as Nevada is a State in which 

 relatively little collecting has been done. 



I have been unable to find any constant character of color 

 or maculation by means of which to separate cnoptcs and 

 battoidcs but, as pointed out by Dr. Skinner, all of the examples 

 of glaucon I have examined show the orange band of the 

 secondaries below, continued on the primaries, and while dimin- 

 ishing in intensity as it approaches the outer angle, nevertheless 

 gives the insect a decidedly inclissa-\\ke appearance. 



L\'cocna riia B. & McD. I have not examined genitalically. 



The genus Philotcs in which the above insects have recently 

 been placed, was erected for sonorcnsis Feld., which differs 

 in general appearance from all of our Lycaeninae, so that if 

 Lycacna is to be split up, cnoptcs and its allies are entitled to 

 a generic name of their own, but I am inclined to place all 

 of the above, together with piasus Boisd., lygdamns Dbld., 

 xerces Boisd., and the recently re-discovered pardalis Behr 

 under Lycacna Fab., (type arion Linn.), on account of the 

 close and distinctive characters of the aedeoagus, and also of 

 the girdle, tegumen and dorsal hooks, sinking Pliacdrotes 

 Scud, and Glaucopsyche Scud.
