Rev. J. Gass reported that he had lately examined another 

 Mound, No. 10, in the Cook's Farm Group, which presented

 was Vanessa antiopa on April 7th ; Pyra.nieis ata lanf a was ^rst 

 seen on April 1 4th, and Lxjcmna jyseudargioltis on April 17th, 

 On April 15th, a species of Simulimi was quite abundant, and 

 caused some annoyance to men and horses. The weather has 

 not been particularly favorable for the development of insects,

 probably the larva of TroGhiliwn iipuliforviie — quite destructive 

 to his currants. 



Mr. Putnam stated that while engaged in collecting insects in 

 Colorado in 1872 and 1874, in Wyoming in 1873, and in Utah 

 in 1875, he had also made a small collection of the Mollusca. 

 This collection, which now belongs to the Academy, was placed 

 by Prof. Sheldon in the hands of Ernest Ingersoll, of Jersey 

 City, for determination, and he has prepared the following re-
