Caiiieades friabilis Grt. 



1875. Grt., Can. Eut., vii, 187, pi. i, f. 5, Afjrotis. 



Eveu (lull fuscous to ash ^ray, the markjiigs usually indefinite iDut 

 on the whole exactly like messona. Secondaiies and underside also like 

 messoria. 



Expands 31-33'""' ; 1.25-1.30 inches. 



Habitat. — New York, Maine, Canada, California. 



Very closely allied to messoria, but darker, ash gray, more evenly 

 colored, the transverse lines and ordinary spots often scarcely evi- 

 dent, and the size perceptibly smaller. 



Mr. Grote curiously failed to recognize the true relationship of the 

 species by comi^aring it with hofitoniensis, with which its resemblance is 

 decidedly remote. 



The species seems rare in the Eastern States, but, if my identification 

 is correct, the species is more common in California. A series of speci- 

 mens received from Messrs. Edwards and Neumoegen, from California, 

 were at first regarded as a local form of messona. Mr. Neumoegeu, how- 

 ever, pointed out a specimen nMnedfrUihUis by Mr. Grote in his collec- 

 tion, which was evidently the same as the Californian series. The west- 

 ern specimens are more ash gray than onessoria, and have a less amount 

 of the fuscous admixture than eastern specimens. 



Carneades fuscigera Grt. 



1874. Grt., Can. Eut., vi, 15», Agrolis. 



Even dull fuscous gray, the lines blackish, more or less distinctly 

 geminate. Ordinary spots outlined, concolorous. Basal line evident. 

 T. a. line rather remote from base, upright, curved between veins, the 

 outer line most distinct, broad. T. p. line sinuate, luuulate, broad. 

 The curve over cell wide; inward curve below less evident. S. t. line 

 sinuate, slightly paler. Claviform very faintly indicated. Orbicular 

 lound, rather large. Eeniform constricted at middle, more or less in- 

 completely outlined. Secondaries smoky, paler at base; an indefinite 

 extra discal line and lunule reflected from beneath. Beneath whitish, 

 powdery, a very distinct broad dusky common line and discal lunule. 

 Head and thorax concolorous. 



Expands 29-32" "; 1.15-1.30 inches. 



Habitat. — California. 



Distinguished by the rather small size and the very even color. 



Carneades orbicularis Smith. 



1887. Smith, Proc. U. S. Nat. Mus., x, 4G0, Agrotis. 



Luteous gray; transverse lines distinctly geminate, dark fuscous. 



Ordinary spots defined, paler. Basal line defined, marked by black 



points beneath median vein. T. a. line upright, slightly denticulate ; 



the included space marked with gray. T. p. line even, very narrowly
