PROCEEDINGS OP THE ACADEMY OP 
[Dec., 
The large collection of North American Hymenoptera has been 
rearranged and some work done preparatory to the rearrangement of 
the Micro-lepidoptera. All the determined Diptera, except a few of 
the family Muscidse, have been arranged in Schmitt boxes and many 
genera and species new to the collection were determined. All of 
Osten-Sacken’s types of Tipulidse and Tabanadie were marked and 
numbered. In the order Orthoptera, reports were completed on the 
specimens collected in Arizona in 1907 by Rehn and Hebard. Con- 
siderable rearrangement has been done in the study series. Dr. P. P. 
Calvert has continued his important work on the collection of Odonata 
and has finished his contribution to the pages of the Biologia Centrali- 
Americana. A large number of Coleoptera has been incorporated into 
the collection, including some interesting material from Fort Wingate. 
New Mexico. The Journal of the Section, Entomological News, has 
been continued and volume nineteen completed with 500 pages and 
25 plates. Two Associates were elected and one member died.
