88 C. H. TYLER TOWNSEND. 



Las Cruces, N. Mex., June 7 ; one female. This specimen seems 

 quite different from the Jamaica male, having the face clear creamy 

 yellowish without any bluish reflection whatever. The scutellum is 

 yellow, and very plainly brown across disc in a transverse band. 

 All the black portions of abdomen shining black. Length only 8 mm- 



Two other specimens, Z 9 , in Mr. C. B. Taylor's coll. agrees well 

 with description. They are from Constant Spring, near Kingston, 

 Jamaica, December 9. 



C W. Johnson (in M8S. ) has taken and identified this species 

 from Rock Fort, near Kingston, Jamaica. 



16. Bacclia lemur O. Sack. 



Las Cruces, N. Mex., June 7 ; one male. It agrees well with de- 

 scription. Length 9 mm. Face and frontal triangle wholly me- 

 tallic greenish black, faintly whitish i)ruinose on sides, with no yel- 

 lowish ; halteres w'ith darker knobs. Abdominal cross bands light 

 blood-reddish. Femora and tarsi more brownish. The cross band 

 of wings extends posteriorly to anal cell, which it does not quite 

 touch, following along the outer side of the posteiior cross-vein at 

 distal end of second basal cell. Extreme proximal end of submar- 

 ginal cell with just a trace of hyaline in the angle. This is appar- 

 ently the case with Osten Sacken's specimens, but is not quite clear 

 from the descriptions. 



17. Bacclia <«agittifera Austen. 



Cinchona, 5000 feet, Jamaica. Described by Mr. E. E. Austen, 

 of the British Museum, in Proc. Zool. Soc. London, 1893, pp. 144- 

 145, pi. iv, fig. 14, from a single female, taken in June. 



18. Bacclia tarclietiuM Walk. 



Dixie Landing, Va. (near Washington, D. C). One male, Au- 

 gust 19. Length 10 mm. Agrees well with Williston's description, 

 except as follows : Hind tarsi wholly, other tarsi on distal half, 

 brownish. The dark brown anterior border of wings fills out the 

 first basal cell (not the first posterior) and just enters the proximal 

 end of the first posterior, thus piissing a little beyond the anterior 

 cross- vein, thence along, but not exceeding (and at first not quite 

 touching) third vein to tip of wing. In addition to the hyaline spot 

 in marginal cell, there is a faint, interrupted, hyaline streak in sub- 

 marginal cell, nearly obsolete, except posteriorly in the left wing.
