OF NORTH AMERICA. 207 



RANGE: (Figure 15) Southern United States, from southern 

 Texas to Florida; south to Mexico, Guatemala and northern Vene- 

 zuela; east throughout the West Indies to St. Croix; and west to 

 southern Lower California. 



Cubensis is typically a tropical species, which, judging by the 

 records, has extended its range northward into the Austroriparian di- 

 vision of the Lower Austral life zone. It is typical of the Central 

 American and West Indian regions. The records are rather widely 

 separated and several of them have not been substantiated by the 

 study of authentic material. The California records which have been 

 examined have proven to be techella. Further records are needed to 

 accurately establish the range of this species. It is quite probable that 

 cubensis has hitherto been confounded with techella.
