The Maryland Academy of Sciences held its annual meeting in 
May, electing Rev. Dr. J. G. Morris, President, and Rev. E. A.

society holds field meetings, and otherwise shows considerable ac- 
tivity. 
The State Geological Rooms at Springfield, Illinois, were burned

The Record of Entomology for the year 1870 is now published. 
The design of this useful annual is to collect from various periodi- 
cals and transactions of societies, the titles of articles and notices 
of new discoveries in entomology, thus giving a record of the 
progress of American entomology each year. In this way the iso- 
lated descriptions of new species, and notes about the habits of 
insects are indicated so that the working entomologist is greatly 
aided in collecting the materials for study. It also gives foreign 
entomologists a summary of what has been done in this country, 
and thus brings the working entomologists of both hemispheres 
into closer relations. The work is advertised in the present num- 
ber.
