Family LYMNADIDAE. 



57 (308) Anosia plexippus Linn. Monarch. 



Very common. This familiar butterfly is always very numerous in 

 late summer. Its migratory habit is well known. In this vicinity 

 single individuals begin to appear as early as April 29. In the first 

 week of September they begin to assemble in large numbers prepara- 

 tory to their southward journey. One of these assembling places is 

 located on 54th Street South and the River Parkway below Minnehaha 

 Park. The writer has seen the trees covered with these gaudy crea- 

 tures for two solid blocks at this place. By the middle of September 

 they are usually gone, but belated ones may be seen much later. I 

 have seen single individuals as late as October 23. May II, October 9.
