"This species seems to be distinct from the luimerous Californian 

 sj^ecies published by Mr. Grote, many of which are unknown to me." 



I have seen this species — I think in the Cambridge collection — and 

 it is as I stated on a previous page one of the obscurely marked ford s 

 of vancouverensis. 



Agyotis semielarata Grt. 



" 5 $ Allied to r/ravis and variGottvercnsis, smaller that the latter 

 and without the pale cast of gravis. A thick, dark browu basal dash 

 extending- into the claviforin, and faintly cut by the t. a. line. Rich 

 brown, with the costal region (especially in the S ) suffused with 

 darker. Spots concolorous; cell shaded with black. S. t. line pale, 

 without the small teeth at the middle and below apices of its allies. 

 Head and collar rich yellow browu ; tegulic shaded with pale, but not 

 so pale as in gravis. Beneath the costal half of secondaries is fuscous, 

 leaving the lower portion of the wing, including the border, pale ; a spot 

 and common line. Above the hind wings are fuscous and rather dark 

 in both sexes. This species may be known by the hind wings beneath 

 being half pale, including the lower portion of the border, which is 

 nsually darker. The three species, gravis, vancouverensis, and semi- 

 cJarata are nearly allied ; their eastern allies seem to be voluhilis^ 

 venerahilis, and stigmosa.''^ 



The figure in the Ilhistrated Essay is very characteristic and recog- 

 nizable, and renders determination easy. Butler says it is the 9 of 

 vancouverensis, but I have seen both sexes of the form. 



Agrotis cJodiana Grt. 



'■'■ $ All the tibiic spinose; fore tibiie with longer terminal spines. 

 Eyes naked. Antenn;e brush like. Allied to gravis, but without the 

 distinct stigmata. Fore wings of a curious purplish biown, with a 

 shading of yellowish. Orbicular small, concolorous, round, with a paler 

 yellowish annulus; reniform concolorous, transverse, moderate, ringed 

 like the orbicular. Claviform indicated, small median shade, blackish, 

 diffuse. Lines illegible; fringes with a narrow, pale yellowish line at 

 base. Ilind wings pale, soiled with fuscous along the margins. Head 

 and collar russet brown, collar with a ])ale line above a deeper shade; 

 thorax mixed pale and brown. Beneath fore wings dark; hind wings 

 pale, with discal marks and faint common line." 



"PLxpanse, 3S""", Washington Territory, 



"A female si^ecimeu, also collected by Mr. Morrison, probably be- 

 longs here. The fore wings are entirely obscure yellowish brown, with 

 the markings lost." 



The figure of this species in the Illustrated Essay is i)oor, but yet 

 recognizable and renders identitication certain.
