TAXONOMY 
Harold Morrison, in Charge 
Frank Johnson, of New York City, spent May 16 consulting with Dr. 
William Schaus. 
Dr. A. G. Béving, the Bureau's Specialist on coleopterous larvae, 
recently received from J. C. M. Gardner, of the Forest Research Insti- 
tute and College, Dehra Dun, India, a series of beetle larvae, including 
cotypes of species described by him in an extensive paper on the imma— 
ture stages of Indian Coleoptera. 
Marsten Bates, an entomologist with the United Fruit Company, and 
located at Tela. Honduras, spent most of a week in the taxonomic unit in 
the latter part of May. He was particularly interested in obtaining de- 
terminations of Lepidoptera which he had collected in Guatemala and Hon- 
_duras, especially determinations of some of the material which had been 
reared by hin. 
Dr. J. M. Aldrich, of the Museum staff, has gone to the western 
United States for two months and will spend some time there collecting 
Diptera in high altitudes. 
It may be of interest to readers of the Bureau's Monthly Letter to 
learn of the death, on May 17, of Dr. George Dimmock, Springfield, Mass. 
It will be remembered that several years ago Dr. Dimmock turned over his 
collections of insects to Dr. E. A. Chapin, of the taxonomic staff, who 
brought them to Washington and arranged for their addition to the collec-— 
tions of the National Museun.

Glenn 0. Robertson has been appointed temporary field assistant, 
and entered upon his duties May 20, at the field laboratory at Coachella, 
Calif., where the work on eye gnats is being conducted. 
On May 17 F. C. Bishopp visited Dr. Baer, of Johns Hopkins Univer- 
sity, at Baltimore, Md., for consultation with regard to the use of blow-— 
fly maggots in treatment of cases of osteomyelitis.
