From previous observations it would appear that L. antiacis and L. 

 xerxes make their appearance in San Francisco about March ist and 

 disappear about the middle of May, I believe. I conclude my remarks 

 respecting the Lycaenac, xerxes and antiacis. with an incident which, no 

 doubt, will be of interest. In March, 1916, I noticed at the top of a 

 lupine a pair of blue butterflies in copulation. I caught the two and kept 

 them alive, and, to my great surprise, on reaching home, I discovered I 

 had a xerxes and an antiacis. I placed both in a breeding cage, together 

 with some lupine branches for food, but they remained untouched. The 

 xerxes, a male, died in two days, and the female, an antiacis, died in 

 five days. A post-mortem examination disclosed two well-formed eggs 

 in the female, but they wilted down after one hour. 



I have often stated that xerxes and antiacis are one and the same 

 species, etc., etc. J. C. HUGUENIN, San Francisco, California.
