204 ALBATROSS EXPLORATIONS, INSECTS HOWARD. 



The above, syuonomy of this interesting fly is reproduced almost 

 wholly from " Lynch Arribalzaga." I have compared a considerable 

 number of the descriptions, and have found no reason to seriously doubt 

 any, though it is true that an exhaustive study of the allied forms from 

 both North and South America may possibly entitle a few of the names 

 to specific rank. The red or reddish hind femora and tibiae have fur- 

 nished ground for some of these names, and Lynch recognizes two vari- 

 eties, which may properly be called Macellaria genuina and Macellaria 

 fulvipes Macquart. These lighter-colored specimens occur among the 

 material from both Montevideo and the United States. Among these 

 ten specimens there is a great difference in size, agreeing in this respect 

 also with those from North America. I have seen the species from all 

 parts of the United States, and from Canada and Mexico, as well as 

 Brazil. It seems to occur over the whole of both continents. Twenty- 

 seven specific names is rather an unusual number for a fly to be bur- 

 dened with.
