20 ANNUAL REPORT OF THE 



REPORT ON THE ENTOMOLOGICAL DEPARTMENT. 



By Nathan Banks. 



For accessions during the past year we are indebted to Messrs. 

 C. P. Alexander, C. F. Baker, F. C. Bowditch, S. E. Cassino, 

 T. D. A. Cockerell, J. H. Emerton, H. R. Hagan, C. W. Johnson, 

 M. D. Jones, W. M. Mann, Herbert Osborn, R. Ottolengui, 

 E. Varas, W. M. Wheeler, and E. B. Williamson. 



Exchanges were made with Dr. H. Brauns, Messrs. C. E. 

 Mickel, R. J. Tillyard, and R. T. Webber. Specimens for study 

 were loaned to ten persons. Besides the local entomologists, 

 ten others have visited the collection for comparison and study. 



The Curator has examined the collection for pests, and noted 

 only a few cases of infestation. During the year more than 

 ten thousand specimens have been pinned, and many labeled. 

 Much of the winter was spent in preparation of revisions of 

 American termites. Papers were prepared on the termites of the 

 West Indies, of Panama, and of the United States. For this 

 purpose material was borrowed from several Museums and 

 Experiment Stations. Numerous types and paratypes were 

 thus added to our already rich collections of American termites. 



Several collections were received for determination. The 

 Canadian Entomological Department sent the Neuroptera and 

 Acari collected on the Canadian Arctic Expedition, the National 

 Museum a small collection of Neuroptera and spiders from China, 

 the Universities of Kansas and of Michigan collections of North 

 American Neuroptera, the American Museum the Neuroptera 

 collected on their Congo Expedition, Pomona College a collection 

 of Acari, and the South Australian Museum a collection of Acari 

 from Norfolk and Lord Howe Island. Several papers have been 

 prepared on these collections. 



In the Diptera, various genera of Asilidae have been studied 

 and the new species described; in the Hymenoptera, the Bembe- 

 cidae have been named and additional Psammocharidae described; 

 in the Neuroptera, unnamed Sialidae, Panorpidae, and Psocidae 

 have been determined or described.
