Eleven specimens, both sexes, Bernard Harbor, Northwest 

 Territory, Canada, collected by the Canadian Arctic Expedi- 

 tion. I saw this material in the Illinois State Laboratory of 

 Natural History, where it had been identified by Mr. Malloch, 

 who called my attention to it. It is to be deposited in the Cana- 

 dian National Collection in Ottawa. A single specimen in the 

 Carnegie Museum, Pittsburgh, is labeled, "82° n. Lat. On the 

 Beach at n. e. extremity of L. Hazen in the interior of Grant 

 Land. June 7, 1908. Peary Arctic Exped." It was collected 

 by J. W. Goodsell, surgeon, along with two specimens of 

 Phormia tcrrcc-novcc RD., which bear the same label, and are 

 also in the Carnegie Museum. This record is probably as far 

 north as any fly has been collected. I have mentioned it in 

 Psyche, xxv, 33.
