This species is only known from Cuba, the Isle of Pines and 

 the peninsula of Florida. In Cuba it seems to occur over the 

 whole island and in Florida it occurs as far north as Gaines- 

 ville. Elsewhere a considerable number of Floridan refer- 

 ences have been given, which it is unnecessary to discuss in 

 this summary. The affinity of couloniana with qnadrata is 

 marked and its origin is to our mind clearly evident. Its dis- 

 tribution and affinity is comparable to the distribution of Man- 

 tolda maya and Phrl.ra maya. 



The tegmina of Cuban specimens of this species are broad- 

 er proportionately than in qnadrata, and in the female sex 

 this is the one evident feature to separate the two forms. In 

 Florida material, however, the tegmina are somewhat narrow- 

 er and the females are almost indistinguishable from Mexican 

 individuals. The Florida males, however, are fully typical of 

 couloniana.
