REVISION OF SPECIES OF THE GENUS AGROTIS. 157 



The s{)('{'it's is not nuViki' piti/chrous in iiiaculatioii and (^olor, bnt lias 

 white scconchiries. It is a close ally of citriculor, but with more tlie 

 groundcolor of misUirata. 



Mr. (Irote, in establishing- his genus Cnrneadcs, seems not to have been 

 aware how large a proijoition of the species of Aijrotis shared the 

 structural peculiaries atrributed to this genus.

An even, pale ash gray, all luaculatiou obsolete. The t. p. line only 

 is evident, white, single, interrupted, somewhat lunate. The s. t. line 

 is iinlicated by a few white scales and is apparently very irregular- 

 Fringes of j)riuiaries with a yellowish line at base. Secondaries whit- 

 ish fuscous, paler toward base; fringe white. Beneath, white, powdery, 

 a distinct discal dot and incomplete transverse line on each wing. 

 Head and thorax concolorous. 



Expands o7 """ ; 1.5 inches.

Another species with uniformly gray j)rimaries and yet not to be 

 confounded with the rather unusually numerous forms with wings 

 almost or quite "as evenly colored. About every group has a species 

 with uniforndy pale gray primaries, and yet even without reference to 

 the structural differences each has a habitus so peculiarly its own that 

 there is but little danger of confusion. 



Only the uni(|ue type of the species in ]\Ir. Ilulst's collection is thus 

 far known to me. 



Mr. Butler says this species is indistinguishable from the Chera hiri- 

 via Ilbn., which occurs in the Al[)ine legions of Euroi»e; l>ut 1 can 

 scarcely accept this conclusion without closer comparison thau Mr. 

 Butler seems to have made in the preparation of his paper.

Ash gray, with various a<lditions of yellow or red, changing the tone 

 of groun<l color considerably. Transverse lines marked by geminate 

 costal spots, else obsolete. S. t. line prominent, pale, interrupted, sinu- 

 ate ; marked by a preceding dusky shade, varying from fuscous to car- 

 mine, red brown. Orbicular, often entirely obsolete, more usually dis- 

 liifguishable as a rounded spot of the shade with which the gray base 

 is sutTused. Reniforin usually percei)tibly <letiued, of the ordinary form 

 and size, interiorly with a dusky sliade, else concolorous. Secondaries
