a, on 
finest lot of Oriental insects of this group ever received at the Museum. 
Previous shipments from Mr. Graham were invariably more or less damaged 
by mold while in transit across the lower and more humid portion of China. 
‘The present lot, however, came throvgh in perfect condition, apparently 
because of the fact, noted in the collector's diary, that he thoroughly 
dried his insect collection in the oven of an American stove. Some of 
these flies are easily recognized as belonging to Huropean species; others 
occur in the Hast Indies and in the direction of Australia, while some 
very striking forms have been hitherto entirely unknown. 
Dr. J. M. Swaine, of the Canadian Department of Agriculture, during 
four days in Washington, spent considerable time in the Division of In- 
sects examining bark-beetles of the genus Ips, and picking out specimens 
of the various species to be sent him for critical study. Dr. Swaine is 
planning an extensive revision of this economic genus and will base it on 
material assembled in both the Canadian and the U. S. National Museums. 
He is using the manuscript notes on this genus left by Dr. A. D. Hopkins, 
and will give credit to Dr. Hopkins wherever it is possible. 
The Section of Insects recently received a good many phone calls 
from people who wanted to know the name of silkworm eggs. It seems that 
a cross-word puzzle appearing in a newspaper had prompted the requests for 
information. Upon looking it up in the Encyclopedia it was found that the 
French word "graine" apparently fits in correctly. 
Dr. William M. Mann, who.is in Europe in.connection with work for 
the Federal Horticultural Board, expects.to return to Washington the first 
week in December. While in Zurope Dr. Mann had an opportunity to study in 
@ number of the mseums. He spent some time with Rev. Wasmenn and other 
specialists on ants, and in the British Museum of Natural History.
