Gundlacli and by Poey and four males from Jamaica have this cell 
succeeded by one or two single cells before the two rows begin, 
and this is a feature very commonly existing in the males from 
Hayti; on the other hand one female from Hayti shows three 
cells immediately after the triangle, then two rows. One Cuban 
male has two rows from the triangle out on the right side; two 
cells, one row for two cells, then two rows on the left. 
The individuals of both sexes from Hayti in the M. C. Z. have 
the two pale green spots on the mesepimeron less separated from 
each other than in Cuban individuals in the same collection, and 
the same is true for the two spots on the metepimeron. Haytian 
and Cuban individuals in the collections at Philadelphia show no 
such difference, however. 
The dark brown in the subcostal space usually reaches, in the 
males, half way or less to the first antenodal; in one male from 
Cuba it extends to this vein on the front wings and slightly beyond 
it on the hind wings; this extreme for the male is very common, but 
not universal, in the females. Hagen (Stett. ent. zeit., vol. 29, 
p. 285) has referred to the variations to be found in the yellow 
coloring of the wings. 
The internal triangle (front wings) is mostly two-celled, but is 
one-celled on both sides of one Haytian male; is three-celled on both 
sides of three Cuban males, 3 Cuban 9 , 1 Jamaica 9 j is two-celled 
on one side, one-celled on the other in 1 Cuban $, 1 Haytian $, 
1 Jamaican $; is two-celled on one side, three-celled on the other 
in 1 $, 2 9 Cuba, 2^,1 9 Hayti; three-celled on one side, one- 
celled on the other in 1 $ Cuba.
