Txit'iculUrrmrs virqinicus Bks. [T. E. Snydor]. On 

 April 25, 1915, my attention fell upon a number of win.i^cd 

 Tennites on the winii:. Tliev were easilv tracMnl to a tinv 

 hole in the wall of a house, from whicli they were issuing, 

 flincrlo file, and flew away. Sentinels or soldiers were 

 standiniT cruard just outside and also inside the hole as 

 the line filed out. This exo<lus continued in a practically 

 unbroken stream for a half hour. The place was watched 

 occasinoally for the next two days, but no further emer-

 neitrhbors, and they continued their merry feast and noisy 

 chatter as long as the insects come out in the air. A sim-

 1920 and May 2"1, 1920. Some of them which were cap- 

 tured lived less than fifteen hours in vials.

'J'Jifcla sp. [A. BuKck]. Ihmdreds of these butterflies 

 were clustered in little independent groups frisking about 

 in the sun on a country road, frequently resting witli ver- 

 tical wings on the grey earth. I could see no occasion for 

 courtship, and suspected that the gregariousness was 

 only for play. This was on September 8.
