Dr. Thaxter, Mr. Lugger, and Mr. Schwarz corroborated Mr. 
Marlatt's experience regarding the great abundance of lepidopter- 
ous larvae in the fall of the present year. Mr. Ashmead said that 
caterpillars were very abundant in Florida in the fall, after a wet 
summer such as the present had been, but he also had noticed 
that they were almost invariably parasitized. 
Mr. Schwarz read a lengthy paper on " Caprification and Fig- 
insects," compiled from the works by Solms Laubach, Fritz 
Miiller, Paul Mayer, and Gustav Mayr. After giving defini- 
tions of the terms " Caprification " and " Caprificus," and a short 
historical review of the subject, he proceeded to discuss the inter- 
relations of the fig insects to the Caprifig and the true Fig-tree, 
under the following headings: i. The flowers and fruits of the 
caprifig and the wild species of Ficus ; 2. Enumeration of the Fig- 
insects ; 3. Life-history of the true Fig-insects (ge\\\.\$> Blast op haga}, 
and fertilization of the wild species of Ficus and the Caprifig ; 4. 
The true Fig-tree, its differences from and its relations to the 
Caprifig, and the process of Caprification. 
Mr. Schwarz added his observations on Ficus aurea and its 
Fig-insects in semi-tropical Florida, and concluded with a few re- 
marks regarding the practical application, to fig culture in the 
United States, of the results of these recent investigations on cap- 
rification. 
Mr. Townsend read the following paper : 
ON THE FALL OCCURRENCE OF BIBIO AND DILOPHUS. 
By TYLEK TOWNSEND. 
The flies of the genus Bibio are often very abundant in certain localities 
in the spring, appearing in swarms and covering all kinds of vegetation. 
The larva;, which live in the earth and feed upon decaying vegetable mat-
