Expanse, 33 mm. = 1.32 inches. 

 ' Habitat. — Quebec, Canada. 



A single female, very like Garneades dissona in superficial appearance, 

 and mistaken for it when first received. The generic reference in the 

 absence of a male is not certain j but it is not likely that the discovery 

 of that sex will necessitate a change. 



5. SETAGROTIS RADIATUS, new species. 



Ground color smoky gray, marked and irrorate with white, smoky 

 brown and black. Head inferiorly yellowish, interantennal tuft also 

 pale inferiorly. Palpi dusky at the sides. Collar inferiorly luteous, 

 tipped with white and black scales. Thoracic tuftings well marked, 

 tipped with white. Patagia white edged and with a black submar- 

 ginal line. Primaries with the median lines obsolete, the subterminal 

 line indicated by the darker terminal space and by a series of inter- 

 spaceal black spots which show it to be very irregular. The veins are 

 dusky, margined on each side by white scales, and the interspaces are 

 dusky, the cell being darkest. There is a slender black basal streak 

 which reaches nearly to the middle of the wing. The median vein is 

 most prominently white marked and after this 3, 4, 6 and 7, which 

 strongly indent the terminal space. The orbicular is obsolete. The 

 reniform is a small, white lunule at the end of the cell. Secondaries 

 white, with a smoky terminal line. Beneath white, powdery, else 

 immaculate, the secondaries a little darker. 



Expanse, 35 to 36 mm. = 1.40 to 1.44 inches. 



Habitat. — Nevada. 



Two males, very much alike, from Mrs. F. O. Herring, in only fair 

 condition. The species is allied to vernilis and infimatis in type of 

 maculation, but is not in the least like them in detail. It has so close 

 a habital resemblance to Garneades nevada, however, that I had asso- 

 ciated the two until a critical examination was made preparatory to 

 descriiDtiou.

CARNEADES Grote. 



In my Eevision of the Agrotids ^ I recognized 108 species as referable 

 to Garneades. Three years later, after having compared the British 

 Museum collections, I catalogued^ 109 names under that heading. Since 

 that time between fifteen and twenty new forms have been described, 

 chiefly by myself, making about 125 nominal species of Garneades. The 

 genus is one of the most difficult and unsatisfactory in the Koctuidse 

 because of the extent of the variation in certain species, and of the 

 tendency to develop local types. In other words, species are forming
