SCIENTIFIC NOTES. 9 



Juncti'lla may be taken on fir trunks, and beaten out of yew- 

 trees (as is the case both at Forres and Witherslack), just in 

 the same way as Mr. Stainton and myself always appear to 

 associate with, and capture iiiaciiliferdla about hawthorn ; but 

 there is very little doubt that all these closely-allied species 

 feed on some species of Caryophyllacece, and that they go to the 

 larger plants for shelter.

IgCIENTIFIC NOTES. 



American Species representative of European. — The North 

 American species, in many instances, bear a very remarkable general 

 resemblance to those of Europe ; and this is especially so with the 

 Rocky Mountain region — take Colorado for instance. I see Vanessa 

 cardui here every day, and meet with such species as Cidaria popi/lata, 

 JSomophila noctuella, etc., while numbers of species are " representa- 

 tive," e.g. : — 



Parnassius Si/iinthens, D. and H. represents F. apollo. 



Pieris olei-acea, Haw. ,, P. napi (but is paler). 



Vanessa niilbertii, Godt. ,, V. urtica (darker). 



Cxnonynipha ochracea, 'Ediw. ,, C. pamphiliis. 



Snieri?ii/ius astarte, Strecker ,, S. ocellatus (greyer). 



Clisiocampa Californica., Pack. „ C. neustria (especially in 



larval stage). 



Calocampa cineritia, Grote. ,, C. exoleta. 



Catocala Caltfornica, Edw. ,, C nupta. 



Metrocai7ipa per/aria, Guen. ,, Af. niargaritata (paler). 



Alucita fnontana, T.D.A.C. MS. (probably n.s.) A. hexadactyla. 

 And so on ad infinitum. (For some very interesting remarks on this 

 subject see Packard, in Ann. Report U.S. Geol, and Geog. Sunuy, 

 Hayden, for 1873, 1874). — T. D. A. Cockerell, West Cliff, Colorado,

Mr. a. G. Butler's " Synonymic Notes on the Moths of the 

 Early Genera of Noctuites." — (From the Transactions of the Ento- 

 mological Society of London, pp. 375-387). In tlie Transactions op the 

 Put. Soc. of London, just issued, is a paper by Mr. A. G. Butler, in 

 which he deals with the synonymy of certain Nocture. Most of these 

 are exotic, and I am unable to criticise the results obtained ; but the 

 synonymy of the British spc:ies included appears to call for some 

 remark. They are : — 



I. On page 380 Peridroma ypsilon, Rott. = Noctua saucia, Hb. 

 (" Schmet," fig. T^']Z) = Agrolis differens. Walk., etc. Is the latter name 

 {differens) synonymous with saucia, Hb. ox ypsilon, Rott.? It cannot 

 be a synonym of both, because ypsilon, Rott does x\o\. = saucia, Hb. 

 \)M\. = suffnsa, Hb. (fig. 134). This is the accepted synonymy oi ypsilon, 

 and we call our British suffusa by the name of ypsilon at the present 

 time. Perhaps, however, Mr. Butler has the original description of
