the inferior abdominal appendage of the male on the eyes of 

 the female. The speaker said these scratches could be seen 

 on the eyes of our common Anax Junius. 



Mr. Wenzel said in Macrodactylus the pubescence on the 

 abdominal segments of the female is rubbed off by the male 

 if copulation has taken place. 



Mr. H. A. Wenzel read an interesting account of his 

 recent trip to the Great Bend of the Rio Grande in southern 

 Texas. 



Mr. Rehn spoke of the difficulties of desert collecting, the 

 conditions in the mountains being far less trying. 



Dr. Skinner exhibited specimens of Adelpha bredowi and 

 californica and gave characters to separate the two. 



Mr. H. W. Wenzel compared the faunas of the Huachuca 

 Mts. in Arizona and Southern Texas, and said that so far

 species that bore out his conclusion. 



Mr. Rehn made some remarks on a recent Orthoptera- 

 coUecting trip made with Mr. Morgan Hebard through the 

 greater portion of the coastal plain of the southeastern

 Austroriparian species and twenty localities extending from 

 Northern Florida to Southeastern North Carolina were ex- 

 amined. A series of fifty-five hundred Orthoptera and much
