Eeport 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. Eight 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, 111., 

 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,' 1 illustrating same with a 

 number of lantern slides made of photographs taken by himself of 

 insects under observation.
