REVISION or SPECIKS OF THE GENUS AGROTIR. 103 



beneath smoky witli an even curved extra-mesial line. Discal marks 

 indicated. Head and tliorax pale brown ; second joint of palpi blackish 

 at the side. Tarsi dotted.''

Habitat.— Texas, iVfay 12; IJelfrafje No. .^)18 (red label). 



"The exterior line on primaries is nnnsnally removed outwards to- 

 wards the s. t. line. Tiiis can not be a form oH auxiliaris, but it is. not 

 iini)r()bable that inconclnna is a form of that protean and widely distrib- 

 uted species." 



1 am not at all certain that 1 know this species. I have never seen 

 any specimen authoritatively determiiuMl and I have had two species in 

 my hands to either of which the descrij)tion may apply, and have named 

 both as immixta. One species, named for Mr. Neuu.oegen, from liritish 

 Columbia, is probably incorrect. Some specimens in the National Mu- 

 seum from the Belfraj?e collec^tion are probably correct. 



Chorizagrotis terrealis. 



1882, Ort., Trans. Kans. Ac. Sci. viii, -17, Agrotis. 



Dark fu.scous brown, costa brick red ; cell, except ordinary spots, 

 blackisii ; a black basal dash. T. a. line o-eminate, traceable only be- 

 tween median and s. m. veins. T. p. line obsolete ; s. t. line indicated 

 by a few pale atoms and the slight contrast between s. t. and the rather 

 darker terminal space. Its cour.se sinuate, hardly dentate. Clavif(U'm 

 distinct, narrow. (Jibicular ovate, oblique, dark gray. Reniform 

 normal, kidney-shaped, also gray. Secondaries smoky fuscous, some- 

 what paler toward base. I>eneath smoky, secondaries somewhat paler, 

 especially near base, and with a distinct discal lunule. Head and thorax 

 concolorous with ])rimaries; collar iideriorly dark brown. 



Expands 37""" ; 1.5 inches. 



Haiutat. — New Mexico. 



This species is very easily distinguished from any of the preceding 

 by the very uniform dark color absorbing the transverse lines, ami by 

 the contrasting re<ldish costa. This form iias the abdomen less de- 

 pressed than either of the others, and thus forms in a manner the con- 

 necting form between this and allied groups. 



Genus RHIZAGROTIS Smith. 



All the tibije spinose, front rough and protuberant, hardly with a 

 cylindrical projection; antennae of male simple, ciliate. Prinuiries 

 normally wide, the costal and inner margins not pirallel, as in CItoriza- 

 {irntis. The two genera, Klii:aprotis and Chorizagrotis^ agree in the 

 structure of front and fore legs, ami are the only genera combining 

 simple male antennti^ with these characters. The peculiar wing form 

 and habitus of the anxiliarix type well separate the species alhed to it. 

 With the exceptiou of a single species, which 1 have named aOnormis,
