WILLISTON: DIPTERA BRASILIANA, 0 
This species seems to have a wide distribution; I have it from 
Brazil, Bolivia, Paraguay, Grenada and Kansas. 
Scatella stagnalis Fallen, etc. 
Scatella obscura Williston, Dipt. St. Vincent, 403. 
( believe that the species described by me is identical with this 
European species, also recorded from Greenland. I have it also 
from Brazil. 
Paralimna obscura, Williston, Dipt. St. Vincent, 390. 
Specimens from Brazil agree with the types. 
Paralimna multipunctata Williston, Dipt. St. Vincent, 390. 
Numerous specimens from Brazil. In some there is a distinct 
cloud on the cross veins. Notwithstanding the absence of a stump 
of a vein, Iam not sure that. this species is not identical with P. 
Uppendiculata and probably also P. secunda.
