REVISION OF SPECIES OF THE GENUS AGROTIS. 179 



All the other species of the j^roiip havedistluctly geminate transverse 

 lines. One series lacks all trace of a basal black dash, which in the 

 other series is always distinct. The tyi)ical frnins lack this basal dash. 



Of this first series eunndes is a narrow-winged form, bhiish white in 

 color, with the large ordinary spots prominently relieved by the black 

 cell. 



The other species vary from carneous gray to fuscous browu or black- 

 ish, all i)ossible shades being represented. 



The secondaries are dusky in both sexes of the following seven species : 



Alticold is easily distinguished from all its aliies by lacking all trace 

 of a claviforuK The species varies greatly in ground color, but is usually 

 some shade of yellowish red. The maculation is very often scarcely 

 traceable, and in such specimens tlie groui) characters are not notable 

 and point rather to pitychrous than to tessellata. With a good series at 

 hand the reference here is easy. 



Rnfula and hasiflaiui are closely allied species which may eventually 

 be merged into geograi)iiical forms of the same. In both the orbicular 

 is incomplete superiorly and the basal space is paler. Rufula is the 

 l)aler, yellowish red in color, median space darker, contrasting somewhat 

 with the basal and s. t. spaces. Jiasiflava is altogether a darker, more 

 powdery form. The basal space is not much paler, and the median and 

 s. t. spa(;es are concolorous. The former is from New Mexico, the latter 

 from British C/olumbia and Sierra ZSevada. 



iSatis is red brown in color, the ordinary spots powdered with yellow, 

 the cell usually not much darker between them. The lines are not re- 

 lieved. 



Jii'ua is a carneous gray species, sometimes more reddish, without any 

 distinct contrasts. The transverse lines are usually more or less obso- 

 lete, the ordinary spots rarely completely outlined, the space between 

 them not much darker. Altogether a very inconspicuous though dis- 

 tinct species. 



Insignatd, under which term I include declarata, campestris, decolor, 

 and verticalis, has the color smooth, even ; the transverse lines some- 

 times very distinct; ordinary spots large, narrowly lunulate with yel- 

 low. CampestHs is that form in which the color is uniform, dark, the 

 transverse lines distinct. Decolor has the lines partly obsolete, the 

 brown colors relieved in basal and s. t. spaces by luteous, sometimes 

 contrasting (piite strongly. Verticalis is more like decolor, but replaces 

 the lighter shades by carneous gray, deepening to brownish in the 

 darkened regions. The latter is a local form, found in Montana and 

 Colorado, and is quite constant. 



Tessellata is distinguished by rougher vestiture, the color not smooth 

 and even, but coarse, powdery; the transverse lines are not so cleanly 

 cut, nor the ordinary spots so well detined. The latter are powdered 

 with gray. •
