Zejndoptera Bhopalocera of Trinidad. 197 



Sometimes found commonly, I believe, in January and 

 February. In Tobago it is reported as abundant. 



The flight of this species is peculiar. Although the 

 insect is powerful-looking, it is very lazy on the wing, and 

 never flies for an}^ length of time. It settles on anything, 

 not infrequently the ground, from which it is often difficult 

 to dislodge it from amongst long grass.

 upper angle of cell and vein 8 from qu^ite near the end of cell. Vein

Bange. Venezuela; Guiana; Amazons. 



Quite common. In flight this species much resembles 

 P. marsyas, but is more jerky. It nearly always settles on 

 a low bush, but does not in my experience ever settle on 

 the ground.
