females collected by Dr. K. Miyajima, in Tokio, 1909 ; unfortunately 

 these types preserved in the British Museum are not complete speci- 

 mens, but much damaged and rather denuded. The original description 

 does not, therefore, agree with the fresh materials in minor points, 

 especially on the pubescence of the thorax, scutellum, and abdomen, 

 and the above description serves as a much more complete one. 



This fly is not a very uncommon as of Japanese species I have 

 records from Tokio, lyo, Nagasaki, and Oita, from June 4th to July 

 loth, but my records do not extend north of Honshu. I caught two 

 females which were biting the belly of a horse, hitched to the fence 

 of a farmer's house near the city of Nagoya, on the first of July, but 

 I have no other knowledge of its habits.
