and other countries, with a view to exchange 
of specimens. 
Mr. ALBERT MuLteER, Curator of the Nat- 
ural History Museum and Librarian of the 
Swiss Entomological Society, of Bern, Swit- 
zerland, has collected a large amount of 
material supplementary to Hagen’s Brbl/othe- 
ca entomologica, a part of which he has 
already published. Dr. Hagen himself has 
in manuscript the main part of the record 
necessary to bring his volumes down to 1868. 
Dr. A. S. PACKARD, JR., of Providence, 
R.I., wishes to obtain specimens of the eggs 
of Oecanthus. ‘‘They are laid in the ter- 
minal branches of the raspberry, plum, oak. 
grape, and almost any shrubs. The rows of 
punctures made by the ovipositors of the fe- 
male are quite easily detected, and may be 
found during the autumn and winter. Send 
twigs by mail.” 
N. Nassonow, of Moscow, gives as the 
results of his investigations into the anatom- 
ical structure and post-embryonal develop- 
ment of ants, 1. that the integuments of the 
head of the imago appear as new formations, 
while those of the thorax and abdomen are 
directly derived from the larval stage; 2. that 
in the organs of the head and thorax no 
destructive processes, but only transforma- 
tions, are to be observed. — Zoologischer
