REVISION OF SPEf'IES OP THE GENUS AGROTIS. 139 



lar, constricted rciiiform, and nniisuiilly distinct and even s. t. line are 

 characteristic, however, and may be relied upon to <iistin<^nisli the 

 sj)ecies. It seems rare, very few specimens liavinf;i: passed through my 

 hands. 



Carneades quadridentata (i. & R. 



1805, Grt. &, Rob., I'loj. Kiit. Soc. IMiil. iv, I'Jl, pi. :?, IV. 2 .and f,, Jgroiis. 



Deep luteons brown or olivaceous ; costa to t. p. line, internal margin 

 and snbnu'diaii strii)e yellowi.sh ; s. t. space also j)al(M' than ground (M)lor. 

 Ordinary si)ots complete, outlined in bhick, whitish, with faint yellowish 

 center. T. a. line single, with two wide outward curves. T. p. line 

 lunulate, very even; s, t. line narrow, pale, inwardly marked by a se- 

 ries of approximate black lunules. Claviform faintly marked, concolor- 

 ous. The dentations on veins 3 and 4 cross the s. t. line and almost 

 attain the outer margin; on veins atid 7 they half way cross the ter- 

 minal space. Secondaries white, a few black scales along outer margin. 

 Beneath primaries dusky, secondaries white; sometimes the primaries 

 are also ])ale. Head and thorax concolorous; collar inferiorly yellow, 

 patagia; white. Occasionally a reddish tinge replaces, oris mixed with 

 the yellow of primaries but the maculatiou remains the same. 



Expands 30-32 '" ; 1.20-1.28 inches. 



1 1 AE IT AT. — Colorado. 



A very neatly marked species, not at all common in collections. I 

 believe I have seen this from New IVfexico and Arizona, but can not be 

 certain. The character of the s. t. line will very readi ly separate it from 

 the preceding which it otherwise resembles in habitus. 



Carneades niveilinea Grt. 

 1882. Grt., Can. Ent. xiv, 21(5, AgroCis. 



In maculatiou very like 'i-dcntata ; so like, that recapitulating all 

 l^oints seems useless, and oidy points of ditference will be given. The 

 size is greater, the color darker, the yellow on costa and veins replaced 

 by white, else by reddish. The collar and patagia* are concolorous, 

 but there is a while stri[)e crossing the thoraxjust behind collar, which 

 will at a glance identify this species. Secondaries and beneath as in 

 ^■(Icninia. 



Expands 35"""; 1.40 inches. 



IlAiUTAT. — Arizona, New Mexico. 



Seems not uiu^ommon species where found, and is very constant. 

 Earely a rubbed specimen will be confused with quadridentata. 



Caneades insertans Smith.

General color a rather sordid yellow. Head and palpi immaculate, 

 collar with a distinct black central line above which the color is some- 

 what more dusky. Thorax with black scales intermixed, forming au
