REVISION OF SPECIES OF THE GENUS AGKoTIS. 79 



specimens, so I can not be certain whether we have not here as in the 

 case of triaufjulum and nornKOiiano, distinct species. On the wliole, I 

 ani inclined to believe Lederer in error, because many specimens cas- 

 ually examined with a lens merely, appear unarmed. As to the amount 

 of variation, that of ground color is remarkabk^ ; eastern material is 

 more or less irrorate with red. Western specimens tend to become 

 much more evenly colored, the color a shade of luteous. The prima- 

 ries are narrower, more equal, and the secondaries have the fringes 

 longer; the i)alpi are held like those of the cupida group, and were it 

 not for the fact thatsuliicient material is at hand to prove the identity of 

 the eastern and western forms, I might have placed some of the latter 

 into the cupida group with a new name, overlooking the inconspic- 

 uous spinulation of the fore tibia. A specimen from the Rocky Mount- 

 ains, received from Mr. Moeschler, would be almost infallibly placed 

 in the cupida group without close examination. Mr. Moeschler indeed, 

 whose knowledge of the Noctuid(c is certainly considerable, entirely 

 failed to recognize its identity. 



It is to be noted here that Speyer, in comparing the specimens of both 

 Continents, speaks of this variability, but comes to the conclusion that 

 they are specitically identical. However, he says also that the anterior 

 tibife of specimens from both continents are unarmed. 



The species is not rare, but is usually more common northwardly. 

 Atro2)os belladonna has been recorded as a food plant of the species.

Yellowish gray with a more or less evident rosy tint. Cell, except 

 ordinary spots, black, costal spot at inception of s. t. line also black, 

 very distinct. Maculation else fuscous. Basal line evident, t. a. line 

 geminate, outwardly oblitpie, but little sinuate ; t. p. line geminate, very 

 even, ui)right, incurved only over cell; the iuner line rather narrow, 

 somewhat lunate; outer wider and very even; a row of veuular dots 

 just beyond outer line. S. t. line paler, well nnirked, sinuate, preceded 

 by a brown shade and a few small black dots. An even somewhat 

 diffused dusky shade crosses the median space. Claviform faintly in- 

 dicated. Ordinary spots concolorous, seldom entirely complete ; orbicu- 

 lar irregularly oval, oblique, open superiorly. Keniform narrow, lunate 

 usually incomplete inferiorly. Secondaries smoky fuscous. Beneath 

 powdered with blacki.sh, a marked common line and discal lunule. Head 

 and thorax concolorous with primaries.
