a 1B wt 
material identified by the older microlepidopterists, and will be one of the 
finest additions to the collection of Lepidoptera in recent years. 
Dr. Frank R. ole, of Redlands, Calif., recently visited the Museum and) 
made examinations of a number of species in the Diptera collection. 
While at Fort Collins in June, Mr. Rohwer was given permission to pick = 
out all of the Hymenoptera types in the collection of the Colorado Agricultural 
College and bring them to Washington as a gift to the National Collection. | 
This extremely valuable lot of types is given as a gift, with the understand— ‘ 
ing that the types may be borrowed in future by either Dr. C. P. Gillette or 
the officials of the Colorado Agricultural Experiment Station. The lot in- 
cludes the types of most of the gall-making Cynipidae described by Gillette, 
the types of bees described by Professor Cockerell from material belonging to 
the Colorado Agricultural College, and also the types of certain wasps and 
sawflies described from the same collections in 1909-1910 by Mr. Rohwer. Alto 
gether, the types of 77 species are included in this very valuable accession, 
which is one of the outstanding accessions for the fiscal year just closing.
