Buenos Aires, April 17, 1905 (A. F. Bayne), tyj^© {$) 
coll. L. B. Front. I have two other Buenos Aires ,^s 
from Mr. Bayne, one dated, I think (but the label is 
nearly effaced), April 18, 1902, the other July 1901, and 
noted as “flying on a bright winter day.” The British 
Museum also possesses two ,^s from Buenos Aires, sent by 
Prof. Berg under the name of Coremia argentina. I know 
of no other locality in the Argentine Republic, ]3ut Mr. 
Bayne informs me it is common in Montevideo, where he 
met with it freely at the end of March 1904 ; the British 
Museum has two of each sex labelled Colon, Montevideo, 
May 3-7, 1896 (Oldfleld Thomas). 
Whether the genus Ochijria has any permanent validity, 
I am not at all sure. It is at present used for the species 
of the Xanthorhoe group which have the ^ antenna fasci¬ 
culate, but I know of no other distinctive characters ; 
and it is doubtful whether argentina has any close affinity 
with them. The shape of wings reminds more of Cctrsia, 
which, however, has quite different structure; and the 
strongly dentate, almost pectinate antenna is really not 
very closely akin to the subdentate antenna of Ochyria 
designata (Hufn.) and its allies. 
A somewhat variable species, yet not .excessively, and 
always y,»resenting a characteristic aspect. The median 
area varies in width, and in the sharpness of its projection 
at and M^; the subterminal is sometimes much less 
distinct and less deeply dentate than in the type, and the 
dark shading proximally to it is not always the same; the 
discal spots are sometimes large and distinct in all wings, 
both above and below, sometimes ([uite minute.
