This form I have traveled hundreds of miles on purpose to get 

 the specimens from the typical locality, and I have spared no 

 trouble or expense to get what I went after. Pursuing this one 

 thing for a dozen years, I have succeeded in getting the best 

 there is. 



Morrisoni is very like Cethura at first sight, but the six figures 

 given herewith will show the regular variation from Cethura, 

 which, as the eye becomes acquainted with the peculiarities, are 

 at once and certainly recognized ; the cell-bar in Morrisoni is nar- 

 rower ; the apical markings are lanceolate or linear, not confluent, 

 not reaching into the orange ; the marbling of underside is less 

 yellow, and more dense.

This new variety is well illustrated by the seven figures above 

 listed. It is a desert form, smaller in size, and paler in ornamen- 

 tation than the foregoing forms of Cethura and Morrisoni, the 

 orange on the apices of the male is less deep, and on the female is 

 nearly or in some instances entirely absent and always pale yellow 

 when present ; the marbling of underside is scanty and dusky. I 

 have not seen any specimen of Deserti that is yellowed on the 

 upperside, except occasionally a little in rays from the base on 

 hind wing's. The figure 60a was given me bv Dr. Behr, the cu-
