REVISION OF SPECIES OF THE GENUS AGROTIS. 87 



Orbicular very lar<^(', <)l)li(|ii(', sulxiiiadrato, oixmi superiorly; outlined 

 in black, then with a lusty aunuliis ; else paler than uu'diau space. 

 Keiiilbnu upri^;lit, rather elou^'ate and somewhat lunate; outlined in 

 black, then a rusty annulus; a narrow central streak yellow. The cell 

 is th(> darkest i»art of the win<j. Secondaries yellow, with an exterior 

 ]uui>lish shade. P)eneath yellow, powdered with red. Thorax dis- 

 tinctly tufted, concolorous witii primaries; head and colhir yellow; ab- 

 domen yellow. 



Expaiuls ;;4-,'3()"""; l.oG-1.14 iiu'hes. 



11 A15ITAT. — Anticosti; New York; Nevada; California. 



A well defiiuMl species allied to perconffua, but much lij^hter and with 

 larger spots, the orbicular entirely dilferent in tbrm and characteristic 

 of the species. 



I have seen the types of both ohlat<( and hilllnna and (ind them en- 

 tirely alike. The species seems conlined to the uorth, or to mount- 

 ainous legions. Mr. Hill's specimens were from the Adirondacks; the 

 California specimens are from the Sierra Nevada. 



Noctua rosaria Grt. 

 1S78. Gil., Itiill. (loot., Snrv., iv, 172, Agroiis. 



Pale, somewhat yellowish red brown, of variable intensity. Trans- 

 verse lines entirely obsoit'te in the dark si)ecimens, very faintly <lelined 

 in i)aler forms; so far as traceable, geminate. T. a. line with a slight, 

 even, out waul curve; t. ]). line very even, parallel with outer margin. 

 T. p. line pale, sinuate, traceable on all speciu)ens thus far seen. There 

 is a distinct dusky nu'dian shade, darkest between the ordinary spots, 

 but even this in dark specimens is hardly traceable. Ordinary spots 

 sometimes (;oncolorous and hardly definable, sometimes very distinct, 

 j)owdered with yellowish scales, moderate in size, normal in form. 

 Claviform very faintly indicated. Secondaries pale yellow fuscous. 

 Beneath powdered with red, and with a more or less evident common 

 extradiscal line and discal luuule. Dead and thorax coucolorous. 



Expands 2!)-32"""; l.lC-l.L'S inches. 



II AJUTAT. — California. 



A very variable little species, no two specimens of wliich are alike. 

 1 have seen no male si)ecimens, and very few females. There is no 

 ditliculty in recognizing the; species as there is no other Californian 

 form at all resembling it while having the same structural characters.
