TAXONOMIC INVESTIGATIONS 
S. A. Rohwer, Senior Entomologist, in Charge. ; 
Dr. E. A. Chapin went to Springfield, Mass., on June 8,. to arrange 
-to bring to Washington the insect collection of Dr. George Dimmock. Or. 
Dimmock is giving the National Museum his collection of adults, larvae, 
slides and notes, consisting of fifteen large double boxes of pinned 
material (amounting to about 35 Schmitt boxes); about 3,500 small glass 
tubes of material preserved dry, consisting of the shed skins of larvae of 
all stages, pupae, some adults, and all of the parasites which emerged in 
the course of Dr. Dimmock's rearings; a small amount of alcoholic material; 
about 2,650 numbered notes, which are in some cases mere skeleton records 
of cap ture on a certain food plant, but in many cases are extremely de- 
tailed, covering three or four pages. Dr. Dimmock has spent about 50 years 
studying the life histories and habits of insects of the New England States, 
and has gathered together a great amount of valuable material. This col- 
lection will be deposited in the National Museum, where it will be avail- 
able to all of the Bureau specialists. It will be distributed and incor- 
porated under the direction of Dr. Chapin. 
R. A. Cushman spent June 20 to 24 in Philadelphia, studying types 
of Ichneumonidae at the Academy of Natural Sciences. 
W. L. McAtee has returned from his trip to Burope, where he ex- 
amined types in the collections at Paris, Budapest, Vienna, Berlin, 
Copenhagen, Stockholm, Upsala, Warsaw, and London. While visiting these 
places he arranged a number of exchanges, and also arranged to borrow a 
great many specimens to aid him in his study on ieafhoppers. 
Lip aie Dane: Chief mi tonetootes of the Mexicari Government, was 
in Washington the last week of June for conference with the Federal Horti- 
cultural Board about the orange maggot, a menace to southern citrus fruit. 
He took the opportunity to confer with the specialists in the Museum, and 
spent one night collecting at light in the Zoological Park. 
T, Ulke recently called on Dr. Dyar at the Museum, prior to leav- 
ing on a collecting trip in the Rocky Mountains National Park of Canada. 
He expects to send Dr. Dyar some mosquito material, 
Stanley Garthside, of Australia, who has been studying forest ento- 
mology at Cornell University, recently visited the Division of Insects and 
met the various specialists there. 
Harold Compere, of Riverside, Calif., recently donated a small col- é 
lection of chalcid types, described by himself, to the National Collection. 
Mr. Compere has previously sent us several similar collections. 
Paratypes of four species of chalcids have been received from 
P, H. Timberlake, of Riverside, Calif., for deposit in the National Collec- 
tion.
