REVISION OF Sl'lXMHS OF THE GENUS AGKOTIS. 113 



Of tlie.suiiie gc'iieial iiii[H';iriiiic(' as siiixjothicd, but diUV'riii^ as follows: 

 The color is iiioie even, tlic coiitiasts less distinct. J\Ie<liaii vein not 

 white; (ilavifoiin short, outlines only black. S. t. line not indented on 

 veins ."> and 4. and as a whole nearei the outer niarjiin. The reniforni 

 also is not diseolorous, but ot" the same color as are tlu^ li.uht shades. 

 There is a strong' reddish tint in [triinaries, and the secondaries arc 

 entiiely dusky. 



li^xpands 35-o7"""; J. 40-1.50 inches. 



llAuri'AT. — United {States east of Kocky iMountains; Canada. 



Tl»o above ditferences are constant, an<l may be relied ui)on to dis- 

 tinguish the species from .siibfjothica under all eircunistaiiees. It is not 

 so common as tudxjothica^ thou<4h like it, freipients golden rod in the day- 

 time. 



The above synonymy is given on the authority of Mr. Butler, who 

 says positively '"'■tricoHH. Lint., is typical /ffcM/Z/'c'ra; Iicrcli.s is a poor 

 variety." Under all circumstances Ciuenei'''s name must stand for one 

 of the forms, since he had all three beTore him, and as herclis was first 

 separated, the name would ordinarily be ap[)lied to tlie tricosa form. 

 Tlie Texan Ibrni which I have called pectinicorniti was probably not 

 before Guenee when he wrote. I think, however, that ilarvey had 

 this form from Texas as the basis of his note in Buff. Bull, lir, 5.

The difierences in luaeulatiini between this species and tricosa are 

 dinicidt to deline, though the insect is at a glance sei)arable, and un- 

 doubtedly a distinct species. It is usually larger, darker, somewhat 

 l)urplish in color, the (;osta and orbicular often entirely concolorous. 

 The reniforni varies from yellow to concolorous with the paler i)arts of 

 w ings pale median dasli always present, and reaching the t. p. line. 

 Secondaries almost nniforndy blackish. 



Expands 37-40"""; l.oO-l.tJO inches. 



Habitat.— With tricosa. 



As a whole this spe(;ies is larger and somewhat more robust than the 

 preceding. The structure of the S antenna is easily made out, and is 

 the best character to distinguish it. The t. a. line in this as well as 

 fWcoA'rt differs from that of A'j(i</of//?"crt in being oblicpie instead of straight 

 across the space between median and submedian veins. From pccti- 

 nicornis this species differs in the antennal structure, as well as in the 

 uniform, darker color.
