NO. 1283. REVISION OF SOME NOCTUID MOTHS— SMITH. 185 



the median vein extends at least to its end and usually to the outer 

 margin; often the vein is inferiorl}' edged with bla(;k. A black nar- 

 row line extends from base into the submedian interspace and forms 

 a loop near the middle of the wing, suggesting a claviform. Above 

 vein 4 there is a triangular dusk}^ area which, on the outer margin, 

 reaches almost to the apex. The terminal space ma}^ be leaden gray 

 or concolorous, or there may be a series of black marks indicating the 

 subterminal line. There may be a small or a large black discal dot or 

 none at all. It may break up into two of equal or unequal size or 

 even into three, and these indicate the reniform. Fringes usually 

 darker, with a pale line at base. Secondaries smoky brown or black- 

 ish, even or only a little paler at the base; fringes white. Beneath, 

 powdery gray over dirty white, the secondaries paler; the dark shad- 

 ing variable, forming no obvious markings. 



IJxpanse. —1.12 to 1.32 inches (28 to 33 mm.). 



Ilahitat.—AnglGaea, New Jersey, June 10, September 3; Cleveland, 

 Ohio, May 5, 9 (Kearfott); Glenwood Springs, Colorado, June 5 

 (Barnes); southern Arizona (Barnes). 



The above are specific localities referring to the fourteen examples 

 now before me. It is probable that the species occurs throughout the 

 Eastern United States and extends into Canada, It is not impossible 

 that the south Arizona example may represent a good species. The 

 single specimen is only enough to create a doubt. The majorit}" of 

 specimens expand about 1.20 inches. 



I have carefully compared Hiibner's figure and have matched it per- 

 f ecth" in the series before me, I have little doubt that it is this species 

 really, though the type was said to come from Buenos Ayres. Hiib- 

 ner's description does not help much; he says it is a nocfua genulna 

 and IMiophila pallida. To Leucania l-alhum it is rather similar, but 

 has an entirely unique middle marking besides other variations. 



On the other hand there is no doubt but that Mr. Grote intended the 

 form here treated when he described his liarveyl. The description 

 fits it perfecth^ and fits no other. 



The range of variation has been partially indicated in the descrip- 

 tion; it is not really great and yet there is enough to make quite a 

 little difterence in appearance. In the one extreme there are no black 

 streaking and no discal dots; in the other there is black everywhere, 

 below the cell, even in the cell; the discal spot breaks up and in every 

 interspace along the subterminal line is a black mark or streak. 



The species has a large economic bibliography which is not here 

 referred to. The larva is known as the wheat-head army worm, 



LEUCANIA OBSCURIOR, new species. 



Resembles aWd'mea in general type of maculation, but is somewhat 

 darker on the whole, with less contrast, the ornamentation much more 

 even. The median vein is white, the shading below it does not usually
