the second joint, and the last joint nearly us long as the four 

 preceding. Ocelli present. Wings have an appendix. The 

 Tubanus suhvarius, Walker, described by Walk ix as a variety 

 of this sjiecies, is distinct (sec bi-low).

PaiKjonia siibvaria, 2 , Walker, List Dipt. pt. i. p. 150 

 (1848), pt. V. iSuppl. 1, p. 128 (1854). [Tabanun sub- 

 varius, Walker, /. c. pt. i. p. 150.] 



This was incorrectly ])laccd by Walk'ir under Tabanun and 

 described by him as T. subvarius in List Dii)t. i. p. 150 (1848). 

 Later in Cat. Dipt. pt. v. 8upi)l. 1, p. 128, he says it is a 

 variety of Pangonia fuscipennis, Wiedein. ; but it is a distinct 

 species and should now stantl as above. Walker's description 

 may be enlarged as follows: — Antennre with the first annu- 

 lation of thinl joint wider than the second joint, and the last 

 joint as long as the four preceding. Palpi curved and long, 

 the same width throughout. Wings with an appendix.

Pangonia umbra, ? , Walker, Dipt. Saund. pt. i. p. 19 (1850). 



This type is not a male as Walker says, but a female. The 

 palpi are long and curved. Wings with an appendix. This 

 rather resembles the preceding group of species, but as 

 the antcnnfe are wanting it cannot be placed with them with 

 certainty. 



Hah. Chili. 



Subgenus Erephrosis, Rond. 

 Wings with first posterior cell closed. Eges hairy. 



Erephrosis ru/o-Iiirta, ? , Walker, List Dipt. pt. i. p. 131 

 (1848). 



The palpi are long and slender, extending but little beyond 

 the projecting face, the two joints about equal in leno-th. 

 Wings with an appendix. This and the five following species 

 are very similar in appearance and in the shape of the 

 al)domcn, which is large and convex. 



Hah. Brazil (AW/). 



Erephrosis piceo-hirta, $ , Walker, List Dipt. pt. i. p. 132 

 (1848). 



This type is a female, not a male as Walker says. Palpi 

 as above. Wings with an appendix.
