Psyche 
[December 
segment. Cremaster short and blunt. General ground color 
dead grass yellow. Eyes, mouthparts, cremaster, and tip of 
tongue case light brown. Two brown spots on pronotum. 
When about to pupate the mature larva becomes dead 
grass yellow and spins a loose cocoon in the grass. Larvae 
which pupated May 18 emerged May 27 nine days having 
elapsed. 
Classification 
Although the extent of our knowledge of larval Hesperiinae 
in Cuba does not yet permit of a workable key to the differ- 
ent species, it already holds more than fair promise for one 
at a later date. 
All of the forms now described may be identified by the 
characteristic head pattern or the color of the head of the 
later instars. For this the moulted head capsule is adequate. 
It will be found that the larvae may be divided into two 
groups, those with a color pattern on the head and those 
without. The patterns are sufficiently constant within the 
species to enable one to separate them by referring to 
Plate IX. Polites baracoa and Poanes radians may further 
be identified by the color pattern on the anal plate. Catia 
misera is characterized by dark ferruginous mottling. In 
this respect it closely resembles Catia otho. Two species 
are known in which the head lacks any definite pattern. One, 
Calpodes ethlius, may be distinguished by its dark orange 
head ; Hylephila phyleus , the other, by its dark brown to 
black head.
