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 Lycaenae, xcrxes 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. 



The Annual Meetings of Societies in Convocation Week. 



The American Association for the Advancement of Science will 

 hold its annual meeting in Baltimore on December 26 to 28, 1918. 

 Owing to limited accommodations, due to war conditions, meetings of 

 the Association and of its affiliated societies will be considerably re- 

 duced. 



The Entomological Society of America will hold only a short 

 business session on December 26, 27 or 28, according to circumstances.
