feel confident that it belongs to the same species. This is 
probably Scudder’s supposed TJ’. multispinosa from Florissant ; 
but the true 7’. multispinosa is a different insect, from the 
Kocene of Wyoming. The Wyoming species is the type of the 
genus, and very possibly better material of it would indicate 
that the Florissant insects belong to a different genus. 
MANTID&. 
Iathophotina costalis, n. sp. 
Tegmen, as preserved (base and apex wanting), about 18 mm. 
long, actual length probably 25; pallid, the veins appearing light 
reddish, perhaps green in life; similar to LZ. floccosa, but with the 
costal field much larger (nearly 2 mm. broad near middle), and the 
inferior branches of the media not forked. The first superior branch 
of the radius is nearly 2 mm. before the apical fork (or origin of last 
inferior branch) of media. The subcostal vein is thin, but quite 
distinct, and is joined to the radius by oblique cross-veins, some 
having a sigmoid curve. The costal field is finely reticulated, agree- 
ing herein with Stagmomantis and not with Photina. The width of 
the tegmen in middle is a little over 8 mm.

By H. Rownanp-Brown, M.A., F.E.S. 
Mr. Wiuuiam Carter, of Hamburg, has been good enough 
to furnish me with a copy and translation of a paper communi- 
cated by Herr August Selzer to the Entomological Society of 
Hamburg, which contains several items of considerable interest 
to those of us who study the bionomics of the western pale- 
arctic butterflies. For some time in the arrangement of the 
genus Hrebia considerable doubt appears to have existed as to 
the actual species of which Hubner’s adyte is a variety. If 
any such doubt remains at the present, it should be finally dis- 
pelled by the results of the breeding experiments successfully 
carried through by Herr Seizer who, from ova obtained from 
Lapland adyte, has derived typical ligea. 
Adyte was common enough at Abisko, Swedish Lapland, 
when I was collecting there in July, 1906 (‘ Entomologist,’ 
xxxix. p. 247), and it was here, also, that Herr Selzer took the 
females from which he bred the typical form in Hamburg.
