RAKE BUTTERFLIES.

both sexes have six perfect legs. It is divided into two sub- 
families, the Pierince and the PapiKdninoe. In the former sub- 
family occurs the genus Dismorphia which is interesting as 
mimicking Mechanitis and other genera of Danamce. These 
butterflies are black and yellow or white with black borders. 
Some of them resemble the delicate European Wood White. 
The small white or yellow black bordered butterflies which 
are so common in Trinidad belong to the genus Eurema. There 
are many species and some are very local. One species I have 
only found in two places, where a certain kind of sensitive plant 
grows, viz. : at Maraval and Carenage. Very possibly the 
larva only feeds oil this plant. 
Of the genus Pieris including the true whites, we have only 
one species in Trinidad — Pieris nionuste. It is more common in 
dry places near the coast e.g. at Chacachacare or the Pitch Lake, 
though it is not infrequently met with inland. 
The Brimstones are represented in Trinidad by Catopsilia 
a genus of which we have several species in Trinidad. The com- 
mon yellow Catopsilia eubule may often be seen coming down in 
flights of six or a dozen to drink at the margin of streams or 
pools and often with it may be see one or two specimens of the 
rich orange Catopsilia argante. 
The second sub-family is represented in Trinidad by six or 
seven species of the great genus Papilio. Some of these must be 
familiar to everyone. 
The commonest species are sEneides and Cymochles. These 
insects when they have recently emerged from the chrysalis and 
before they have had time to get rubbed are very handsome. 
The wings are black with large patches of green red or white 
variously arranged, according to the species. The sexes also differ 
considerably. These two species are commonly seen hovering 
round bamboo clumps or low bushes. The local name is Cattle- 
heart.
