East coast of Florida; Indian River (C. V. Riley coll.), Palm 

 Beach (Dyar), Miami (Schaus coll.). 



Type. — No. 10739, U. S. National Museum. 



This species has been known as Cosmosoma omphale Hiibn. and 

 Cosmosoma aitge L., but it differs from the species bearing those names 

 in the extent of the black band, which begins on the second abdominal 

 segment and does not touch the thorax. 



Syntomeida jucundissima, new variety. 



The form of Syntomeida epilais occurring in southern Florida differs from its 

 Mexican and central American representative in the greener tint of the wings, the 

 reduction of the white markings, the wing spots being smaller and the markings on 

 the feet less, and in the different color of the terminal abdominal segments, which 

 are scarlet in the Floridian form, crimson in the Mexican one. The above new name 

 is proposed for the Floridian subspecies.
