against a strong easterly wind. Forty were counted in 

 five minutes crossing a front of about 100 yards. The wind 

 was so strong that the butterflies wore caught in eddies at 

 the edges of fields of tall sugar-canes, and a large number 

 would be sheltering in such spots only to take the first 

 opportunity to escape and continue their journey in the 

 right direction. 



After this the migration continued, according to the 

 manager of Tarouba estate, in diminishing inmibers for 

 some days, luit on the 5th October, when I next visited 

 this locality, only a single specimen was seen, although this 

 belated example was nevertheless hurrying in the same 

 direction as the others. 



Mr. Fahey of Palo Seco (south coast) informs me, with- 

 out being able to give exact dates, that the moth was 

 abundant in his district, flying from south to north from 

 over the sea for days and days. 



Although he has resided for some years in the district 

 he has iiever seen any flight in the reverse direction. 



Dr. E. R. de Verteuil, a resident of the same district, 

 says on the contrary that he has seen them flying from 

 Trinidad to Venezuela, but cannot recall the year or month. 



1918. There was apparently no migration of C. kilns 

 to Trinidad in this year. I saw the moth at intervals during 

 the year at the following places and dates : — May 14th, 

 Arima-BIanchisseuse road, three specimens. June 16th, 

 Siparia, two specimens. July 11th, La Fortunee, one speci-

 (P. Creteau), September 11th, La Fortunee, one specimen 

 flying west (P. C'reteau). September 25th, Caroni, one 

 specimen. October 20th, Palo Seco, one specimen. 

 November 18th, Hermitage, one specimen flying north- 

 east. 



1919. The same remarks apply to this year also. 

 Individual specimens were seen as follows : — February 8th, 

 Rock-Penal road. July 15th, Harmony Hall. July 27th, 

 Maracas Valley (Northern Range). July 29th, Maracas 

 Valley and Caroni. September 8th, Hermitage, one flying 

 rapidly north-east.
