ReEporRtT OF THE ENTOMOLOGICAL SECTION. 
St. Louis, Mo., Jan. 16, 1911. 
To the Academy of Science of St. Louis: 
Another year has passed in which the Entomological Section has 
done work of which it may well be proud. Hight meetings were held 
and at each one of these considerable enthusiasm was shown. 
At the January meeting Prof. J. F. Abbott was elected to succeed 
himself as chairman and Mr. Hermann Schwarz as secretary. Mr. 
Hermann Schwarz reported on the meeting of Illinois and Missouri 
entomologists held at the home of Dr. Wm. Barnes, of Decatur, IIl., 
January 16th. The enormous collection of North American Lepidoptera 
possessed by Dr. Barnes proved instructive far beyond the expecta- 
tions of many. The conference was attended by twenty-two persons. 
Mr. J. T. Monell described the manner in which aphids puncture 
leaves. Mr. Rau, Mr. Monell and others spoke of the good work done 
by the Section during the past year and the cheerful outlook for its 
future. : 
At the February meeting Prof. J. F. Abbott read a paper on 
‘“Mimicry in the Genus Limenitis L. and the Papilioninae, Models of 
L. ursula.” 
' At the March meeting Mr. Phil Rau read a paper on “Life History 
and Color Changes in Stagomantis carolina,” illustrating same with a 
number of lantern slides made of photographs taken by himself of 
insects under observation.
