 mander Islands, 1897 to 1922. The aid, Miss Doris M. Cochran, 

 besides identifying about 2,000 reptiles and. amphibians, continued 

 work on her Herpetology of Haiti and Santo Domingo, and nearly

In the division of fishes, the assistant curator in charge, B. A. 

 Bean, has determined and partly reported on collections received 

 during the year, particularly material from China and Africa. 



In the division of insects, Dr. J. M. Aldrich, the associate curator, 

 has continued the study of the muscoid flies and has published a 

 number of papers on them, while several other papers have been 

 prepared and are ready for the press. Charles T. Greene studied 

 critically and reported on the larvae and pupae in the family 

 Sarcophagidae and has nearly completed a similar study of Leptidae. 

 He has also made good progress on a, catalogue of the type specimens 

 of Diptera in the National Museum. The amount of research work 

 in the various sections of the division of insects by the honorary 

 custodians and other members of the staff of the Bureau of Ento-

 report. Dr. H. E. Ewing prepared the outline of a paper on the 

 North American scorpions. Among the numerous studies by A. N.

 S. A. Rohwer has made some progress in studying the Oriental 

 Sphecidae submitted by Doctor Baker and in addition has completed 

 another paper dealing with the Scoliidae forwarded by him after the
