Chrysops costatus, g 2, Fabr. 
Three females from Jamaica, 45.110 (Gosse) ; one male 
from Villa Nova, Amazons, 55. 44 (Bates); two females 
from St. Domingo, 55. 1 (Tweedie) ; six females from Ama- 
zons, 66. 53 (Bates). 
The two females from St. Domingo approach the descrip- 
tion of those from San Rafael, Vera Cruz, by Townsend, the 
outer branch of the two blackish abdominal markings being 
abbreviated and not longer than the inner one, and the 
distal border of the band of the wing is somewhat convex. 
The male differs only by the base of the wing being some- 
what darker. 
Rondani states his amazonius resembles subfasciatus, Macq. 
(I presume he means subfascipennis, Macq., as there is no 
Chrysops described under the former name), and vulneratus, 
Rond., of which last it is perhaps only a variety. Osten 
Sacken makes vulneratus the same as costatus, and I have little 
doubt that amazonius is also a synonym of the Fabrician 
species, to which subfascipennis, Macq., is evidently nearly 
related. 
Chrysops letus, 2, Fabr. 
Two females from Brazil, 68. 4 (Saunders Coll.), and 
another female labelled 68. 4. 
One of the specimens has the face rather dark, which 
makes it doubtful whether it belongs to this species. 
Chrysops guttula, 2, Wiedem. 
One female from Para, 68. 4. 
Chrysops crucians, 2, Wiedem. 
One female from South America, 54. 13 (Saunders Coll.). 
Chrysops oculatus, ¢ , Bigot. 
There is only one specimen (the type female). On com- 
paring it with the description of C. molestus, Wiedem., it
