transverse line on the proximal half of the secondaries; it is also of a more mottled 
rufous colour beneath. Further particulars have been given under the preceding species. 
E. hegesia overlaps E. claudia in the Southern United States and in Mexico and 
Guatemala, but in Costa Rica and throughout its wide range in South America it is 
foundalone. In Guatemala it usually occurs in places of a lower level than those where 
E. claudia flies, and probably is not found at a higher elevation than 4300 feet at 
Coban and 3000 feet at San Gerénimo, whence it descends to the sea-level at Panzos.

This name was applied by Hiibner to a “ coitus ” of Pieride in 1816, and for this reason 
was transferred by Messrs. Butler and Kirby to Prerts daplidice and its allies, a new name 
being given by each author to the present insects. As, however, Doubleday had in 1848 
fully described this genus under the title Synchloe, we prefer to adhere to his ruling. 
The secondary male sexual organs in Synchloe are very like those of Melitwa 
(M. cinxia). The tegumen is atrophied, and is simply a transverse bar with no pro- 
jecting median hook; the harpagones are short and rounded, but armed with two 
terminal strong hooks recurved towards each other like the horns of an ox. This 
arrangement is very different to what we find in Argynnis (A. selene). The antenne 
have thirty-nine joints, the terminal sixteen forming a moderately abrupt club. ‘The 
palpi are like those of Melitwa, the terminal joint being thicker than in Phyciodes, 
and the middle joint swollen gradually towards the middle. The front legs of the 
male are clothed with fine hairs. The coxa is rather stout, <4 femur - trochanter, 
tibia femur, tarsus (single-jointed*) = tibia. In Melitwa cinxia the tarsus is 
two-jointed and=4 tibia. The claws of the other legs are curved; and the tibia is 
without spines on the upper surface as in Aelitea. 
The metropolis of Synchloe is certainly Mexico and Central America, where no less 
than ten out of about thirteen species are found. The extralimital species are :— 
S. perezt, peculiar to the island of Cuba; S. ¢ulita, peculiar to the island of Puerto 
Rico; and on the continent of South America we find S. narva in Venezuela, a close 
ally of S. donplandit. In North America races of S. lacinta occur in Texas and 
Arizona.
