Type: Cat. No. 15580, U. S. N. M. 



Locality: Glen Echo, Maryland, June 3, 1898 (R. P. 

 Currie). This species comes very close to the European 

 curvipalpis Zetterstedt, but the two males of that species in 

 collection (Bonhill, Dumbartonshire, Scotland, May, 1907- 

 1908, J. R. Malloch) have the arista bare, the basal swelling 

 much more pronounced, and elongate; the frons half as broad 

 as width of head; the last section of fifth vein about equal 

 to the penultimate section, and the outer cross vein before 

 wing middle. It may be well to indicate here that the name 

 curvipalpis (Dipt. Scand. Vol. 7, 1848, p. 2782, species 44) 

 was given to this species because of a misapprehension on the 

 part of Zetterstedt, who mistook the vibrissae for a prolongation 

 of the palpi. Schiner in Fauna Austrica followed him in this 

 respect. The species was afterwards described by Kaltenbach 

 as bicornis (Pflanzenf. 1873, p. 330, species 33). 



In the collection are three specimens which may be males 

 of affinis, but their condition is so poor that I do not con- 

 sider it desirable to either place their description on record as 

 such, or describe them as belonging to another species. 



The localities are. Key West, Florida, January 1 and Feb- 

 ruary 6, 1869, (Hubbard-?) and one from North Carolina, 

 without other data. 



Food-plant unknown.

Plate XXXI, Fig. 38. 



Male and female: Frons black; center stripe opaque, orbits and 

 the weakly defined ocellar triangle shining; breadth of frons in female 

 barely one-third as wide as head, in male slightly wider; each orbit 

 equal to about one-fourth the width of center stripe; four rather weak 

 orbital bristles present; in addition to the bristles there is an irregular 

 row of very short hairs nearer to eye margin; frons in profile declevitous, 

 not projecting; antennse brown-black, small; third joint not as long as 

 broad, rounded in front, distinctly pilose; arista black, basal fifth 

 thickened, tapering, almost bare, length equal to from its base to 

 second uppermost orbital bristle; face black, concave, mouth margin 

 slightly produced; cheek black-brown, narrow, almost linear at posterior 

 margin, distinctly higher anteriorly, but not very much produced; 

 vibrissa in male fasciculate in form, the length not equal to that of 

 cheek, and not very conspicuous; in female the vibrissa is distinct 

 and almost as long as in male, but consisting on only one bristle; mar- 

 ginal cheek bristles much weaker then vibrissa; proboscis brownish
