PROCEEDINGS OF THE ACADEMY OF 



[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 TabanadsB 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.
