In his address as retiring president of the Cambridge Entomological 
Club, Mr. Wm. H. Ashmead discussed “ The Habits of the Aculeate 
Hymenoptera.” The address is being printed in Psyche, and is a paper 
of unusual biological interest. 
Mr. F. J. Buckell discusses, at some length, the proper name for the 
butterfly, variously known as Danais archippus or Anosia plexippus, 
and concludes that the insect should be called Anosia archippus. 
Mrs. A. T. Slosson publishes’ an interesting list of insects taken in 
the alpine region of Mt. Washington. 
Mr. Howard Evarts Weed issues, as Bulletin 27 of the Mississippt 
Experiment Station a valuable discussion of insecticides, and their 
application. . 
In Bulletin No. 23 of the Maryland Experiment Station, Dr. C. V. 
Riley treats of some Injurious Insects of Maryland. 
Mr. H. F. Wickham records” some interesting observations on the 
habits of oceanic Hemiptera. His observations indicate that Halobates 
may be drowned by submergence; and open up again the question as 
where these insects remain during stormy weather. 
In his annual report on the gypsy moth, Prof. C. H. Fernald says: 
“Tn 1891, some experiments were made to determine what could be 
done toward entrapping the male moths by exposing females. In the 
spring of 1893, Prof. Shaler recommended that the monitor trap be 
tried on a large scale. This was done by enclosing the females in boxes 
` eovered on two sides by fine wire netting, and attaching to such boxes 
two sheets of paper covered with a resinous coating to which the male 
moths adhered. Fifteen traps were exposed in Malden, and 1,771 male 
moths were caught. The fact that so many moths were destroyed at a . 
small expense, seems proof that trapping will prove an effectual and 
inexpensive method of preventing the increase in the numbers of the 
moth, especially as the males now seem to be comparatively scarce.”
