648 Dr. G. B. Longstaff's Bionomic Notes on Buttcrfiies. 



Calisto zanfjfis, Fabr. 



This is quite a shade-loving butterfly; it keeps close to 

 the ground flying amongst herbage, usually for a very 

 short distance at a time. It was once seen flying freely on 

 a rainy day. 



Mackfield, Jamaica, 29 January, 1907. Three C. zangis 

 seen to settle (one of them twice) with a list away 

 from the sun of about 30° (from the vertical). 



Christiana, Jamaica, 2 February. C. zangis seen to list 

 away from the sun. 



Mile Gully Mt., Jamaica, 14 February. C. zangis seen to 

 settle and then, with a jerk, list about 30°. 



Port Antonio, Jamaica, 4 March. Three C. zangis seen to 

 list from the sun, usually but 20°-30° ; one was seen 

 to increase the list in two movements. 



During my visit to Ceylon in the spring of 1908 I did 

 not see any butterflies list. 



Ccenonynipha pam.ijliilus, Linn. 



Early in June 1906 Mr. W. J. Kaye told me that he 

 had recently noted in Surrey the common G. pamphilus 

 settle with its Avings up, but leaning over in such a way 

 that the sun's rays fell vertically upon its wings. Going 

 down to Devonshire the next day I naturally wished to 

 confirm Mr. Kaye's observation, but though I have seen 

 the butterfly in some abundance at Mortehoe its appear- 

 ance there is most uncertain, so much so that neither in 

 1904 nor in 1907 did I come across a single specimen in 

 the parish ! However, in 1906 I did succeed in finding 

 three specimens which I observed with the following 

 results. 



Mortehoe, 10 June, 1906, C. j?am2?M?«s : a specimen 

 seen to settle six times; always across the sun ; with 

 head sometimes to the right, sometimes to the left ; 

 the wings up ; in every case with a list away from the 

 sun so that its rays were about normal to the wing 

 surface. 



Mortehoe, 13 June, 1906. A specimen seen to settle 

 several times ; across the sun ; the wings up, but with 

 no list.
