Hab. Norra America, California?, Sanzalito ?—GUATEMALA (Conradt, in mus. 
Staudinger), Totonicapam 8500 to 10,500 feet (Champion).—EuRorx *°. 
The numerous specimens received (about fifty) from Mexico and Guatemala vary to 
a great extent, and I am quite unable to separate them from others from Europe. 
The insect also occurs in California. Many of the Central-American examples are 
almost identical with some of the English ones in my own collection. We figure six 
beautiful varieties, five males and one female, all from the summit of the Cordillera, 
Totonicapam, Guatemala. According to Mr. Champion, the insect is not uncommon 
in the Los Altos region of Guatemala, where it may be found on the trunks of pines 
in the daytime.
