from Java, received for identification. There has also been received 
for determination, and of which the Academy receives a set, several 
collections totalling over three thousand specimens from East 
Africa from the Berlin Museum, a series from Mexico from the Field 
Museum, several from the American Museum of Natural History 
from the same country, and a very extensive collection from the 
Transvaal Museum. 
Mr. Hebard has worked during a considerable portion of the year at
