INVESTIGATIONS OF INSECTS AFFECTING MAN AND ANIMALS 
F. C. Bishopp, in Charge 
On July 6 a conference was held in Dr. A. F. Woods's office, to 
discuss the problem of the cattle grub, and the work on that insect pro- 
posed by the Bureaus of Entomology, Animal Industry, and Chemistry and 
Soils. Representatives of a number of industries interested were pres— 
ent, as well as representatives of the bureaus mentioned. 
Early in July H. M. Brundrett left Dallas, Tex., for Schenec— 
tady, N. Y., to conduct investigations on the cattle grub. The work was 
shifted later to Herkimer, N. Y., and Mr. Brundrett has now returned to 
Dallas. He stopped over in Washington en route in both directions. 
In July R. W. Wells, a former employe of the Bureau, was appointed 
Associate Entomologist, and Harold S. Peters and Emory C. Cushing As— 
Sistant Entomologists. Mr. Wells has been following commercial work 
Since his resignation from the Bureau, several years ago. He and Mr. 
Peters are now carrying on cattle grub investigations at Herkimer, N. Y. 
Mr. Cushing is temporarily assigned to studies on mosquitoes, with head— 
quarters at Mound, La. David G. Hall, a temporary appointee, has been 
asSigned to investigations of the cattle grub. 
On July 50 Dr. Wm. A. Riley, of the University of Minnesota, was 
a visitor at the office. 
TAXONOMIC INVESTIGATIONS 
Harold Morrison, in Charge 
Dr. C. E. Mickel, Assistant Professor of Entomology and curator 
of the insect collection in the University of Minnesota, arrived in Wash- 
ington July 1, under an appointment with the Bureau of Entomology, and 
Will spend about 23 months arranging the Museum collection of mutillids. 
Dr. Mickel has recently published revisions of Some of the North American 
genera of Mutillidae, and has others in progress. 
Dr. H. E. Ewing, assisted by C. S. East, a taxidermist of the Na-— 
tional Museum, spent most of July in eastern Virginia and North Carolina, 
getting records of vertebrate hosts for chiggers and other ectoparasites. 
It is of interest to note that no Chiggers were recorded on small mammals, 
but many on ground—frequenting birds—~-all new host records for chiggers. 
Messrs. Ewing and East also took an unusual oestrid larva from the white— 
footed mouse. 
Prof. K. L. Henriksen, Assistant Curator of the Zoological Museum 
of Copenhagen, Denmark, arrived in Washington on July 24 and will stay un- 
til August 9, when he will leave for the International Entomological Con- 
gress in Ithaca, N. Y. Although Dr. Henriksen has made a special study of 
trilobites and coleopterous larvae he is also interested ina general way 
in the entomological collection of the Museun.
