In response to a letter received from Mr. Banks at the June meeting, 

 Mr. J. T. Monell and Dr. C. H. Turner were appointed to serve on a 

 National Committee of Nomenclature. 



At the October meeting Mr. Hermann Schwarz reported that, on the 

 16th of October, 1913, he found on a clothes prop in his yard, a crysalis 

 of A7iosia plcxippus. He was convinced that a Crysalis formed that 

 late in the season would remain such throughout the winter; hence ho 

 considers this a hint that this butterfly hibernates in the pupal stage, 

 instead of migrating southward and returning in the spring as is the 

 comnaon belief.
