feel confident that it belongs to the same species. This is 

 probably Scudder's supposed T. multispinosa from Florissant ; 

 but the true T. multispinosa is a different insect, from the 

 Eocene 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^. 

 Lithophotina 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 L. 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 n-early 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.

Mr. William 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 palse- 

 arctic butterflies. For some time in the arrangement of the 

 genus Erebia considerable doubt appears to have existed as to 

 the actual species of which Hiibner'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 Selzer 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.
