is brassy golden in color. There is some very indistinct white pubes- 

 cence on pleurse. The length is 2 ram. (abdomen is flexed under 

 aiDically) ; length of wing 2.5 mm.

2. Chrysops calli<lus Osten Sacken. 



Dixie Landing, Va., June 1 to July 6. Four females ; ends of 

 /\-shaped marking on second segment prolonged laterally along the 

 hind margin, in two specimens strongly and in the other two weakly ; 

 segments of venter toward tip brown, margined with yellowish. The 

 cloud of fifth vein coalesces hardly, or not at all, with the cross-band. 



3. Clirysop!^ coiiitatus Fab. 



Kingston, Jamaica ; recorded by F. Walker from Jamaica (List 

 Diptera in British Museum, pt. v, 1854). Best description is given 

 by Wiedemann (Auss. Zw., i, 198). One female September 11, from 

 Dr. W. H. Strachan ; and one female November 18, captured on 

 Museum window. 



What is usually supposed to be the first ring or section, of the third 

 joint of the antennse in Chrijmp-^ is, in this species, at least in the 

 above two specimens, annulated or segmented with unusual distinct- 

 ness, making the third antennal joint appear as if composed of eight 

 annuli. The frontal callosity is of about the same rusty yellowish 

 color of the face, but with the posterior edge brown. In both speci- 

 mens also, the outer branch of the two blackish abdominal markings 

 (of tergum) extends to (not onj the sixth segment, instead of only 

 to the fifth as Wiedemann describes. Tlie inner brancli extends to 

 (not on) the fourth segment. Thus the outer arm or branch of the 

 markings extends the width of two segments farther posteriorly than 

 the inner branch. The venter of abdomen has a lateral longitudinal 

 blackish browii vitta, beginning about middle of second segment, 

 continuing to posterior border of third, and more faintly on fourth 

 and fifth segments. 



The two basal cells, and also the anal, are hyaline, except a slight 

 infuscation of former at proximal end, and of all at distal end. The 

 discal cell and last posterior contain each a hyaline spot, that of the 

 latter reaching the margin. Fii'st two joints of antennse long and 

 very nearly equal.
