AMERICAN DIPTERA. 355 



I have three females which I cannot distinguish in any way from 

 the description of European specimens. One was collected by Mr. 

 C. Abbott Davis at Providence, R. I., May 30, and was sent me by 

 Mr. C. W. Johnson ; another is from Mt. Washington, N. H. (Mrs. 

 Slosson) ; and a third trom New Bedford, Mass. (Hough). 



Hypocera clavata Lw. (Plate vi, figs. 22, 23.)

 Aldrich, Canad. Ent., xxiv. 



Male ami female. Very black, moderately shining, all the frontal setae directed 

 upward. Antenna' red, palpi luteous Wings hyaline, costa with very short 

 cilia, second vein simple, middle tibiae with two setae above, others with one. 

 Length 2.0-3 mm., of wing the same. 



Stout, very black, moderately shining; front broad, rather convex, punctured, 

 all bristles directed upward. Antenna 3 reddish, with ochraceous tinge; palpi 

 rather broad, luteous; apex of the abdomen, especially in the male, more shining 

 than the rest of the body. Front legs dull testaceous, varied with fuscous; hind 

 legs black or piceous black, knees testaceous ; hind femora very black ; middle 

 tibiae above near base with two setae, the others with one. Halteres black. 

 Wings hyaline, costa black, very finely filiate. Of the strong veins the second 

 is simple, the apex dilated ; of the slender veins the first is extremely flexed 

 near the hase. 



District of Columbia (Osten Sacken). 



This species is allied to Phora femorata, but is easily to be dis- 

 tinguished by the color of the antenna 1 and palpi. 



Besides the original type there is in the Museum of Comparative 

 Zoology at Cambridge a specimen from New Hampshire. In the 

 collection before me are two specimens, both collected by Mr. C. W. 

 Johnson, one from Boston, the other from Montgomery County, 

 Pa., July 4, 1892; and a headless ? apparently of this species 

 from Douglas County, Kans. 



Besides its lighter color, this species differs from femorata by the 

 sharper curvature of the fourth vein in the wing.
