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.

Here again the forms seem to depend on locality more than 
season. 
In case any one should desire to examine more closely into the 
matter I append notes on the weather conditions during the period 
in which I was collecting.
