I cannot quote any further distribution Avith certainty, 
I fully believe the insect is conspecific, or at least very 
closely related, with Hammapteo'a ralaria (Dogn.),* and 
Warren’s name may have to sink; but I cannot assert 
this positively in the face of serious questions which have 
not yet been entirely set at rest. Typical ralaria is from 
Loja, Ecuador, whence also comes a form that M. Dognin 
considers conspecihe, yet “not quite typical”; and it is 
this latter form—which also occurs in other parts of 
Ecuador, in Peru, and I think in Paraguay—that I have 
compared with Warren’s type of ochribasis. Again, the 
last-mentioned is somewhat discoloured, being stained at 
the base (so that the name is unhappily chosen), and this 
does not make identification easier; and Mr. Warren, who 
has been in constant correspondence with M. Dognin, 
determines a different species as ralaria, and a different 
species as ochribasis ! In any case the true ochribasis is 
not an Entephria,, for it has not the biangulate disco- 
cellulars of the hindwing. If it is not a Hammaptera, 
it will no doubt prove a Euphyia. The $ is unknown 
to me.

Schaus’ and both Warren’s types were from Peru. I 
have compared the two last-named with a specimen pre¬ 
sented by Schaus to the British Museum as halisma. 
Except that in obtusaria the median band is slightly 
narrower, there is no appreciable difference.
