The low summer temperature on the Pacafic coast permits 

 this species to come as far south as latitude 37°. The most 

 southern locality in which the currant fruit fly has been recorded 

 in California is Watsonville, which is exposed throughout the 

 year to the cold coast fogs. In reference to the vertical distri- 

 bution, the pest has been captured at Ute Creek (Lat. 37-38°), 

 Colorado, at an elevation of about 9000 feet. 



To determine whether the currant fruit fly occurs in any 

 country other than Canada and the United States, specimens of 

 Epochra canadensis were sent to various fruit fly specialists who 

 have travelled extensively in various parts of the world. Mr. 

 Geo. Compere, chief quarantine inspector at San Francisco, who 

 has spent nine years of almost continuous travelling over the 

 w^orld in search of fruit fly parasites has never met with Epochra
