J. L. Webb and H. S. Peters returned to Washington on July 17, 
having completed the season's investigation of cattle grubs in Vermont. 
With a view to securing specimens of ectoparasites of birds, or infor-— 
mation concerning such ectoparasites, they made contacts with several 
men before leaving New England. 
On July 10 Messrs. Webb and Peters called upon C. H. Whittle, 
Peterboro, N. H., a vice president of the Northeastern Bird Banding 
Association, to discuss the matter of bird ectoparasites, especially 
Hippoboscidae and Mallophaga. On July 11 L. F. Fletcher, of Boston, 
another vice president of the same association, was interviewed con- 
cerning the securing of parasites of birds in connection with bird 
banding. On the same day they had an interview with C. W. Johnson, of 
the Boston Society of Natural History, Boston, Mass., in which the mat- 
ter of bird ectoparasites, principally Protocalliphora, Hippoboscidae, 
and Mallophaga, was discussed. The Bennett collection of Mallophaga 
was examined by Mr. Peters in the short time available. On July 12 
they met a bird—banding party on Cape Cod, made up of Dr. John B. May, 
State Ornithologist of Massachusetts, C. B. Floyd, Secretary—Treasurer 
of the Northeastern Bird Banding Association, and 0. L. Austin, Jr., a 
graduate student in ornithology at Harvard University. These men are 
engaged in banding nestling common terns on the islands off Chatham, 
‘on Cape Cod. Some time was spent with them in going over the work of 
banding and in discussing the matter of parasites of birds. Mr. Austin 
has sent to the Bureau many Mallophaga from collections made by him in 
Labrador, British Guiana, and British Honduras. 
A move has been inaugurated by the Office of Public Buildings and 
Public Parks for the elimination of mosquitoes in public grounds and 
around public buildings, especially the White House. On July 16 F. C. 
Bishopp attended a meeting called to discuss plans of procedure. . The 
others attending the meeting were Col. U. S. Grant, 3rd, Director of 
Public Buildings and Public Parks, Dr. W. C. Fowler, District Public

ert D. Harden, of the Army Medical Corps, Dr. C. E. Waller, of the
