TAXONOMIC INVESTIGATIONS 
Harold Morrison, in Charge 
Dr. D. M. DeLong, Professor of Entomology at the Ohio State Uni- 
versity and a collaborator of the Bureau of Entomology, spent nearly the 
entire month of March in Washington in the Division of Insects of the 
National Museum working on specimens belonging to the genus Empoasca. He 
is engaged in the preparation of a critical review of the American species, 
with particular reference to the species of economic importance. He re—- 
turned to Columbus on March 27. 
Dr. Karl Friedericks, of the University of Rostock, met several of 
the specialists in taxonomy of the bureau on March 25, and in the after— 
noon was taken by Dr. Chapin to the colony of Zoraptera near Falls Church, 
Va., which was discovered by the latter some time ago, and which has been 
under his continuous observation since. 
Miss Alma W. Rutledge, a graduate of the University of Illinois, ac- 
cepted a temporary appointment, effective March 5, as Junior Scientific 
Aid in the Taxonomic Unit. 
A. G. Weeks, of Boston, a well-known student of Lepidoptera, called 
at the National Museum March 6 to consult with Dr. William Schaus. 
On March 19 H. S. McConnell, of the Maryland Agricultural Experi- 
ment Station, at College Park, called to obtain from the bureau's spe— 
cialists in taxonomy information on some parasitic Hymenoptera in which 
he is interested. 
Morgan Hebard, of the Philadelphia Academy of Sciences, spent March 
20 with A. N, Caudell, studying the National collections of Orthoptera, 
with special reference to a paper which he is: preparing on the Orthoptera 
of Colorado. 
W. W. Stanley, of the Agricultural Experiment Station of the Uni- 
versity of Tennessee, at Knoxville, called at the National Museum on March 
29 to consult bureau specialists. He was especially interested in seeing 
the collections of cutworms and leaf-—cutter bees, and while here obtained 
a list of references to publications on the habits of the latter. 
Prof. G. C. Crampton, of the Massachusetts Agricultural College, at 
Amherst, a well~known authority on insect morphology, called on March 18 
to get identifications of some interesting insects from Chile which he ex— 
pects to use in his morphological work. The fauna of Chile contains soms 
insects of decidedly primitive structure, which Professor Crampton finds 
unusually interesting and important. 
Dr. W. A. Hoffman, of the Medical School in Porto Rico, visited the 
National Museum on March 16 to examine types of some minute blood-sucking 
midges.
