Very widely distributed and common from the southern 
United States, the Bahamas and West Indies to Brazil, 
Paraguay and Argentina. Varies very little except in size, 
and I have not been able to discover any indication of 
geographical variation. I suspect that Gnophos fuscovariata, 
Wallengr., Wien. Ent. Monats., iv, 176 (1860) = Diselisio- 
procta fuscovariata, Wallengr., Eugenies Resa, Ins., 379, tab. 
vii, 6 (1861), is related to this, but from the figure and 
description I cannot actually identify it. Some notes on 
its structure, kindly sent me by Prof. Aurivillius, 
confirm the suspicion that it belongs to the Larentiinae, 
in spite of Wallengren’s erroneously placing it among 
Boarmidae. 
As I have not been able to satisfy myself concerning the 
best generic position for the present species, I have allowed 
it to retain provisionally that given to it by Warren and 
the other workers at the South American fauna. In spite 
of some resemblance to Philereme = Scotosia, it caniiot 
remain there, on account of the non-biangulate discocel- 
lulars of the hindwing; nor can it be referred to Ochyria, 
Hiib. {Gypsochroa, Hulst, nec Hiibner), as it has not even 
the true fasciculate $ antenna.
