Three males of this species have been examined, all from Guadala- 

 jara. They agree perfectly in structure, but exhibit some diversity 

 in coloration. The black on the lateral lobes of the type is not so 

 distinct in the other specimens, and the general features of the color 

 pattern more subdued in both of them.
