What I take to be the Wet form has the under side 

 irroiated with grey; the Dry form with reddish. 



Terias elathea, Cram, 



In one of the Caracas specimens the black streak is 

 very faint and might be described as obsolescent, in the 

 other there is no trace of the black streak and scarcely 

 any orange. 



It will be observed that this aberration was in both 

 species met with in dry, or somewhat dry specimens, but 

 I scarcely think that it can be considered as the extreme 

 dry form, at all events without more material. 



Pieris 'phileta, Fabr., Jamaica, Venezuela, Tobago. In 

 this species the seasonal differences are well known. 



Wet-season form. Under side. Wings white, with but 

 faint traces of yellow. 



Dry-season form. Under side. Hind-wing and tip of 

 fore- wing yellow ; veins and lines in interspaces brown. 



Pieris jphileta, Fabr. 



Here again the forms seem to depend on locality more 

 than season.
