Mr. J. G. Grundel reported a trip to the Santa Lucia Mts., 

 in San Luis Obispo Co. He found that the Catocalse about 

 willows varied greatly in color and selected spots resembling 

 their coloration ; he wondered whether they were conscious of 

 their color. 



Mr. Fuchs determined some Coleoptera taken by Mr. Grun- 

 del, namely: Cychrus convergens var., Cicindela oregona, and 

 Pterostichus castafieipes. He exhibited some Sesiidse bred from
