284 AMERICAN DIPTERA. 



of the wing, except where mentioned, not being reticulated with 

 semi-hyaline spots, having only two brown spots beyond the eye- 

 spot of the submarginal cell, the orbits not whitish, and the unspot- 

 ted femora, will readily separate these two species.

These specimens seem to agree well with Loew's description, but 

 the spot just before the apical band of the wing does not go beyond 

 the second vein, except possibly in a faint shadow. 



In addition, these specimens have the following characters: the 

 thorax of females have two elongated brown spots just behind the 

 suture line ; a velvety black spot on each post alar callus, at the 

 root of scutellum, with a conspicuous series of black, posteriorly 

 directed bristle-like hairs; the posterior margins of the second and 

 third segments have a brown border, sometimes interrupted in the 

 middle, and the entire lateral margins of the third segment some- 

 times brown. 



The thorax of % is similarly marked, but there seems to be no 

 bristle-like hairs on the black post alar calloses, and the abdomen is 

 spotted with numerous minute brown spots, but only two large spots 

 on the posterior dorsal margin of the second segment. 



The shining black spots on the scutellum of both sexes are very 

 large and separated only by a narrow pollinose stripe, which with 

 the stripe at the base, give the spots a right angular appearance. 



These characters are not noticeable in another specimen I have, 

 but until more material is studied I do not think it advisable to 

 separate them.
