The species of this genus were monographed by myself in the Proc. U. S. 

 Nat. Mils. Vol. XXI, in 1898, and Dr. Harrison G. Dyar supplied descri])tions 

 and a classification of the then known larvse. In 1909, Sir George F. Hampson 

 described the species of the world in Vol. VIII of his Catalogue of the species of 

 Noctuidae in the British Museum, and Dr. Dyar there adds further information 

 on the early stages in that publication. 



The species included here are those that are recorded as from California in 

 the publications above cited, with a very few additions of species almost certain 

 to occur within the State. 



My own collection is very deficient in California material. 

 I. Primaries evenly trigonate, outer margin oblique, apices 



somewhat drawn out : markings tend to break up into 

 spots or blotches on transverse lines ; psi marks prominent 2 



Primaries abruptly widening at base, apices rectangular 

 or a little rounded, outer margin a little arcuate; 



vestiture smooth, psi or dagger marks prominent. 7 



Primaries broader, more evenly trigonate, apices 

 rectangular, outer margin more even; vestiture 

 rough or squammose, psi or dagger marks wanting 

 Primaries short, trigonate, stumpy in appearance 

 Primaries longer, narrow, subequal, apices rectangular 



or a little produced 

 No longitudinal basal dash, line or streak

 mark opposite anal angle, defined and crossing t. p. line 

 Secondaries grayish white in male, smoky gray in female ; 

 primaries bluish ash gray ; dagger mark opposite anal 

 angle less distinct and does not cross t. p. line 

 Primaries with ground color white, maculation 



tending to obsolescence 

 Primaries with ground color blue gray 

 Primaries with ground color ash gray 

 Orbicular and reniform both present
