104 EEPORT OF NATIONAL MUSEUM, 19U. 



The transfer of specimens to the permanent trays made little prog- 

 ress, owing to a delay in the delivery of the trays ordered for the 

 year's use, but much is expected to be accomplished in this direction 

 during the current year. Preliminary to the preparation of a faunal 

 collection to be added to the exhibition series for the District of 

 Columbia, special efforts have been made to assemble as much local 

 material as possible suitable for the purpose, and it is expected that 

 a good representation of several orders will soon be ready for 

 installation. 



The associate curator of the division, Mr. J. C. Crawford, continued 

 his studies of the Hymenoptera, and, in addition to several paj)ers 

 published, he completed a contribution on the bees of the genus 

 Coelioxys in America north of Mexico. Of the material secured dur- 

 ing the biological survey of the Panama Canal Zone a part was 

 worked up during the 3'ear, and accounts of the Lepidoptera, by Dr. 

 Harrison G. Dyar and Mr. August Busck, were issued. Mr. J. E. 

 Malloch finished several papers on the Agromyzidee and Simuliidee, 

 the titles of which and of other communications by custodians of the 

 division will be found in the bibliography at the end of this report. 

 Mr. William Schaus continued his work on the Lepidoptera assem- 

 bled by himself and designated as the Schaus collection, and pub- 

 lished one paper descriptive of several new genera and 136 new 

 species of Noctuidse, all but three of which were secured by himself 

 and Mr. J. Barnes in Guiana. For nearly five months Dr. E. Mar- 

 tini, of Hamburg, Germany, made studies on the collection of mos- 

 quitoes, and for two months Mr. S. B. Fracker, of the University of 

 Illinois, was at work on lepidopterous larvae. Other entomologists 

 who made investigations at the Museum were Mr. William T. Davis, 

 of New Brighton, N. Y. ; Prof. A. L. Melander, of Pullman, Wash. ; 

 Mr. C. P. Alexander and Mr. Harold Morrison, of Cornell Univer- 

 sity; and Mr. L. H. Weld, of Evanston, 111. Material was lent for
