in dense masses wherever the ground was moist. It is 

 strictly accurate to say, that the swarm of butterflies on 

 the wino- was so dense for miles that you brushed aj]i;ainst 

 them with your clothes as you walked by." 



Yellow Biilterflies in Panama. 



At Bocas del Toro, Panama, I made the two followinj^' 

 notes in my diary :■ — 



" 6th May, 1917. Yellow butterflies flying steadily 

 across the river at Guabito |ou the border between Panama 

 and Costa Rica] from north to south, 8.30 a.m. Fifteen 

 seen in five minutes, and only one flying in opposite 

 direction." 



" 4th June, 1917. Guabito. Yellow butterflies going 

 due north at 10 a.m. No wind and very hot sun. I saw 

 one liundred or more pass, and none in reverse direction." 



Yellow Butterflies in Costa Rica. 

 Mr. Jemenes, whom I met at Suretka, Costa Rica, in- 

 formed me that migrations of yellow butterflies are of 

 coimnon occurrence at San Jose, Costa Rica, and that the 

 butterflies always fly from north to south. This was 

 confirmed by another man in the same house, who had also 

 resided many years at San Jose. 



Yellow Butlerflie.s in Alississippi. 



Mr. L. S. Mestier, chemist at the Usine St. Madeline, 

 Trinidad, informs me that about the middle of November 

 1917 at Ocean Spring, Mississippi, U.S.A., after a cold spell, 

 he saw a large flight of yellow butterflies flying from west 

 to east across a northerly breeze. The flight lasted for 

 about an hour. The butterflies were " by thousands " 

 " like leaves," and were mostly at a height of from six to 

 ten feet. 



Mr. Mestier had lived for four years at Ocean Spring 

 (whicli is on the coast about fifty miles west of Mobile), 

 i3ut this was the first time that he saw any flight of this 

 nature. 



White Butterflies in Trinidad. 



Mr. Fahey of Industry Estate, Trinidad, says that some 

 years ago he saw a large flight of " small white butter- 

 flies " at Manzanilla on the east coast of Trinidad, flying 

 from east to west and cominn inland from over the sea.
