During the early part of the month W, V. King and G, H. Bradley 
mace a mosquito—breeding survey in salt-marsh areas along the Atlantic 
Coast from Georgia to Virginia. Stops were made at Savannah, Ga, 3 
Beaufort, Charleston, Pawley's Island, and Myrtle Beach, S. C.; Wile 
mington, Orange City, and New Bern, N. C.; and Norfolk, Va. 
H. S. Peters spent the period March 21 to 28 in northern Pennsyl- 
vania investigating ectoparasites of wild animals, in cooperation with 
the Biological.Survey and the State Game Commission. He reports in 
part as follows: "A special beaver-—trapping season,extending from 
March 1 to April 10, offered an opportunity to examine a large number 
of beaver, The examinations included some animals that were still 
alive, some recently trapped, some trapped 3 or 4 Gays, and a number 
of pelts which had been removed from the animals2 or 3 weeks. It was 
found that about 95 percent of the beaver evidently were rather heavily 
infested with the peculiar beetle Platypsyllus castoris Rits. Trappers 
stated thet the beetles were generally present in large numbers, often 
as many as 100 on one animal. Two beaver were found with about uO 
specimens but the writer could find no damage caused to the hide or 
animal in any way. The best pelts seemed to have the most parasites. 
The beetles seemed to leave the host as soon asthe animal was skinned, 
They were found on live beaver, and even on beaver which had been dead 
as long as 4 days but not yet skinned, I could not find-any beetles on 
any pelt, even though it had just been removed from the animal. They 
appear to leave as soon as the bddy heat is gone." Mr. Peters had 
an opportunity to examine two deer that had evidently died of starva- 
tion, as their stomachs were full of balled-up laurel and’ rhododendron, 
The .common biting lotise Tricholipemrus virginianus Peters was present 
in large numbers and 2 few-specimens of the sucking louse Cervophthirius 
-crassicornis Nitzsche were taken. Late in the winter and early in the 
spring, when the usual food of deer becomes scarce, they sometimes 
attempt to eat laurel and rhododendron, These Plants are somewhat 
poisonous and not very digestible, and cause the death of some deer each 
year. Ordinarily the starving deer are found heavily infested with ex. 
ternal parasites, 
A great deal of interest has been created by the use of blowfly 
maggots in infected wounds of humans, and surgeons in all parts of the 
United States and in many foreign countries are now using the maggot 
treatment. The interest which is being taken in this novel method of 
treatment is well shown in the great demand for information upon the 
subject. While a considerable number of articles have been written, 
they are scattered widely throughout the biolofical and medical liter~ 
. ature of the world, However, through the excellent library facilities 
in Washington, Wn. Robinson of this Division has been able to compile 
& list of the publications-on this subject and this has been issued in
