666 Dr. G. B. Longstaff's Bionomic Notes on Butterjiies. 



I brought home 21 specimens; of these 6 were taken 

 between 18 Dec. and 8 Jan., 5 of them were " wet," only 

 1 "dry." 



Fifteen were taken between 20 Jan. and 9 April ; of 

 these 8 were " dry," 3 " wet," and 4 intermediate. 



As the dry season advanced the dry form more or less 

 displaced the wet form. 



Dated specimens in Mr. W. J. Kaye's collection taken 

 in the wet season are mostly wet; the same applies to 

 specimens in the Hope Collection. Judging from the 

 condition of many of the specimens I met with, it is a 

 long-lived insect and therefore considerable overlapping 

 may be anticipated. 



Anartia jatrojylise, Linn. Two forms are fairly well 

 marked : — 



Wet-season. Under side. Ground colour nearly white ; 

 markings often conspicuously edged with scarlet. Ocelli 

 black with blue centres. No transverse bar on hind-wing. 



Dry-season. Under side. Ground colour shaded with 

 grey ; markings edged with ochreous or reddish-brown, 

 ocelli often blue only, orange-ringed. Hind-wing with a 

 transverse grey bar. 



Anartia jatrophie, Linn. 



The table would appear to point to the forms being 

 local rather than seasonal. The " dry " specimens, it will 

 be observed, were all taken in Jamaica and were all of the 

 race, or sub-species jamaicensis, Moschler,* but, on the 

 other hand, not all the jamaicensis were " dry."
