chotrypes) parasitic on Cecidomyid larvae which live in the sap 

 vessels of freshly cut wood. The parasite has a long slender 

 abdomen which varies in length in different individuals and is 

 used in placing the eggs into the vessels of the wood. 



Mr. Frost spoke of recent collecting of beetles and the different 

 identifications of them by several experts whom he had consulted. 



Mr. Walker spoke of finding a small insect larva in freshly 

 exuded spruce gum. This led to a discussion of insects in gum 

 and amber, which was joined in by Mr. Denton, Prof. Wheeler, 

 and several other members. 



At the meeting of June 14, Mr. L. W. Swett, who had lately 

 been to the White Mountains, reported an unusually early season. 

 At the Glen lilac and apple were in bloom, Papilio turnus, Colias 

 plilodice, Pieris rapce, Argynnis bellona and Thecla Iceta were fly- 

 ing. The nights were warm, 55° to 60°, and collecting by light 

 was tried on the Mt. Washington carriage road. Many species were 

 taken, but in small numbers. 



Mr. Dodge showed 140 species of Coleoptera, all taken on June 

 12, near Wilmingion Junction. 



The first meeting of the autumn was held on September 13, and 

 Mr. C. W. Johnson gave an account of collecting at Mt. Desert, 

 Maine, in June. The mountain maple, several species of Cornus, 

 and raspberries were in bloom, and many insects were swept from 

 the plants, among them many not before found on the island. 

 Two thousand species of insects are at present known on Mt. Desert, 

 more than half of them Diptera and Lepidoptera. 



Mr. 0. E. Plath showed several nests of bumble-bees which he 

 had kept in boxes through the summer, and told about his obser- 

 vations on them, which will be published later in the year.
