are species from eggs laid by captive females of one or either, and this 
can easily be done, in the way I have elsewhere indicated, by any one 
taking the trouble to attend to the matter on the spot. A strong point in 
favor of the identity of these forms would be a great similarity between 
the larvæ that produce them. The young larva of arthemis I know, and 
it is essentially different from that of wrswla. I expect the larva of 
proserpina to exhibit the form of arthemis, and not of wrsula. It would 
not be difficult to establish the facts one way or other next spring, to 
some of your readers. 
NOTE ON CATOCALA WALSHII, Epwarps.

I have received, through the kindness of Mr. C. V. Riley, a specimen 
of this fine species which has been heretofore unknown to me. It is, 
perhaps, a little larger than wwijusa and very different in character (also, 
therefore, distinct from junctura, from my recollection of that species in 
the British Museum) ; it resembles the European eocafa in the appearance 
of the forewings : these are evenly intensely powdered with dark scales on 
a grey ground color which becomes yellowish brown over the median 
spots and subterminal space. The species thus differs strongly from 
Meskei, in which the forewings are pale grey and resemble in color more 
distantly those of the European eecfa, or perhaps our American /arfa. 
There is a more prominent discal tooth on the t. p. line in Walshiz, 
wanting in eocata. On the hind wings the median band is much as in 
Arizonae, narrower than in Æ/eskei or wnijuga (in which it is broadest) 
and not continued below vein 1, whereas in c/ocafa it attains the internal 
margin. Beneath, the band is narrower than in cocafa, and also non- 
continuous. The median spots on the fore wings above are more like 
elocata than wnijuga. On the hind wings the inner edge of the marginal 
band is much as in Arizonae, even, not ragged as in elocata; the ante- 
postical sinus is cleanly cut. Beneath, the white bands on the primaries 
are broader than in e/ocafa, and even than in wzijuga, and the space 
between the median band on the hind wings and the marginal band is 
wider on either surface in Wadshii than in either of its allies. The red of
