C, F, W. Muesebeck, of the Gipsy Moth laboratory, has spent about four 
weeks in the Section of Insects identifying parasites and studying the bra- 
conid genus Microbracon.- Mr, Muesebeck has devoted considerable time to this 
difficult genus and hopes to be able to complete the revision of the North 
American species the coming season, Before returning to his headquarters at 
Melrose Highlands, Mass., he will visit the collections in Philadelphia and 
also those in New Haven, to examine types. 
C. T, Greene is preparing a paper on the puparia of Sarcophagidae. 
This paper will be arranged similarly to the one recently issued by the 
National Museum and describing the puparia of the Tachinidae. Mr. Greene 
is very anxious to secure as many specimens and species as possible and would 
appreciate it if the field men would send in puparia definitely associated 
with the adults. His studies have shown that the front end or cap offers 
many useful characters, and care should be used in seeing that this is pre- 
served when possible, 
N, I, Iskander, Assistant Entomologist of the Egyptian Department of 
Agriculture, visited the Section of Insects October 9. Mr. Iskander was 
especially interested in the collection of Coccidae and in the arrangement 
of the collections, especially in the tray system, and also in the organiza- 
tion of the work in the Section of Insects. 
On October 9 A, B, Champlain, Curator of Insects of the Bureau of 
Plant Industry, Pennsylvania Department of Agriculture, brought to Washing- 
ton a collection containing all of the types of insects previously in the 
custody of the Pennsylvania Department of Agriculture. This collection con- 
tained 126 specimens and 57 species. Fourteen of the species were repre- 
sented by holotypes, 35 by paratypes, and 6 by cotypes. This is the first 
State institution to give all of its types of insects to the National Col- 
lection, and it is hoped that other institutions will follow the example of 
Pennsylvania, The types deposited in Washington are more accessible to 
specialists than when housed in State institutions, and are much safer.
