manent insect trays, which have been designed for the better preser- 

 vation of their contents than under the old system. 



The custodians attached to the division, who are mostly members 

 of the Bureau of Entomology, were mainly occupied in the working 

 up of material with reference to its economic bearing, but in the 

 course of their researches they discovered and described many new 

 species, as noted in the bibliography. Mr. J. C. Crawford, associate 

 curator of the division, published two papers of a revisional char- 

 acter, and Dr. A. D. Hopkins, custodian of forest tree beetles, pre- 

 pared a list of generic names and their type species in the coleop- 

 terous superf amily Scolytoidea, which was printed in the Proceedings 

 of the Museum. 



Besides members of the Museum and Bureau staffs, a number of 

 entomologists consulted the collections. Mr. William Schaus was 

 present most of the year, and submitted for publication a voluminous 

 paper entitled "A generic revision of the American moths of the 

 subfamily Hypeninae." Others who worked in the division, generally 

 for only short periods, were Mr. George Shinji, of the University of 

 California; Mr. Charles Dury, of Cincinnati, Ohio; Dr. F. E. Lutz 

 and Mr. A. J. Mutchler, of the American Museum of Natural His- 

 tory ; Mr. Frank L. Thomas, of Athol, Mass. ; Mr. B. Preston Clarke, 

 of Boston, Mass.; Mr. Henry Bird, of Eye, N. Y.; and Mr. C. P.

Plants. — The past year surpassed all of the preceding 10 years,
