164 Mr. n. B. Williams' 7?wonZ.9 of 



seen in numbers on July 3Lst, 1912, at Carrington (St. 

 Phillips), after a gale from the south. I am indebted to 

 Mr. Bovell, Director of Agriculture, for this record. 



Mr. No well, of the Imperial Department of Agriculture, 

 informs me that the insects of this migration were all 

 rapidly eaten up by the local species of Tyrant Fly-catcher 

 {Tj/r annus rostral as Sclater). 



1915. There is a single specimen in the collection of 

 the Imperial Department of Agriculture labelled " Barba- 

 dos, August 1915." 



It has been pointed out that in two of these years (1901 

 and 1912) in which they occurred in numbers in Barbados 

 they were also recorded as abundant in Trinidad. 



Cy daman leilus off the Coast, of Venezuela. 



On 15th January, 1917, I saw a specimen of this same 

 moth flying over the sea about four miles from the coast 

 and about 100 miks west of Trinidad. 



Cydainon leilus in Costa Rica. 



On 4th March, 1917, I noticed a distinct migration of 

 this insect at Suretka, Talamanca, Costa Rica (near the 

 Atlantic coast and the Panama border). At 4.15 p.m. 

 they were seen in numbers all going very fast towards the 

 west (up the river). There was at the time a slight north- 

 east breeze and the sky was overcast. Three specimens 

 were captured, of which two were females and one a male. 

 They were passing from 1.15 to 5 p.m. Two were seen at 

 5.15, and the flight ])roh;il)ly continued a little after this. 



At 8.45 a.m. on the following day, still cloudy, one was 

 seen flying in the same manner in the same direction, but I 

 left the locality a few minutes afterwards and saw no more. 



On the 20th of the same month I saw a single specimen 

 flying full speed in the same direction at Guabito, which is 

 about twenty miles east of Siiretka and just over the 

 border-line into Panama. 



Mr. Jemenes, who had lived near Suretka for some years, 

 informed me that the migrations of this moth were frequent 

 and usually from north to south, and that in the district 

 of San Jose, Costa Rica, where he had also lived, he had 

 seen migrations in the same direction.
