Vol. xxv] ENTOMOLOGICAL NEWS 231 
Summer Work on Lake Erie. 
The Lake Laboratory of the Ohio State University at Cedar Point, 
near Sandusky, Ohio, will be open to investigators free of charge 
from June 22 to Sept. 1, and for instruction (fee) from June 22 to 
July 31, 1914. The courses of study include one on Entomology by 
Mr. W. J. Kostir. 
Do House Flies Hibernate? (Dip.). 
Mr. E. E. Austen, in the Entomologist’s Monthly Magazine, for 
February, 1914, page 30, under the above title calls attention to Dr. 
Henry Skinner’s article under same title which appeared in the News 
for July, 1913, page 304. Mr. Austen states that Dr. Skinner’s asser- 
tion, “House flies pass the winter in the pupal stage and in no other 
way,” is directly at variance with the results obtained in England by 
both Newstead and Jepson. However, he further says that in the 
recent investigations along this line by the Local Government Board, 
no house flies were found among those hibernating. To further inves- 
tigation along such lines he makes an appeal to the readers of that 
journal to send collections of hibernating flies, accompanied with proper 
data, to the Local Government Board for determination. It will be 
interesting to learn the results of such a campaign. 
Entomological Literature. 
COMPILED BY E. T. CRESSON, JR., AND J. A. G. REHN. 
Under the above head it is intended to note papers received at the 
Academy of Natural Sciences, of Philadelphia, pertaining to the En- 
tomology of the Americas (North and South), including Arachnida and 
Myriopoda. Articles irrelevant to American entomology will not be noted; 
but contributions to anatomy, physiology and embryology of insects, how- 
ever, whether relating to American or exotic species, will be recorded. 
The numbers in Heavy-Faced Type refer to the journals, as numbered 
in the following list, in which the papers are published, and are all 
dated the current year unless otherwise noted, always excepting those 
appearing in the January and February issues of the News, which are 
generally dated the year previous. 
All continued papers, with few exceptions, are recorded only at their 
first installments. 
The records of systematic papers are all grouped at the end of each 
Order of which they treat, and are separated from the rest by a dash.
