Mr. Grote in his New Check List notes that these species are prob- 

 ably identical — in this he is correct. I have compared examples from both 

 continents and find them identical ; any difference there may be between 

 extremes from each hemisphere is readily filled by selection from abun- 

 dant material from each section. The markings are different from any 

 of the other species, and are better shown in the figure than they could 

 be described by me. Expands 1—1 J inches, 26-32 millim. 



Habitat.— Europe and America. 



The larva feeds on Artemesia vompextas and also on the flowers. Of" 

 a pale yellowish green with three blackish lines, one dorsal and the others 

 on each side ; entirely covered with fine black points and short lines ; 

 each point bearing a number of fine hairs ; head brown red with black 

 spots. Also varies somewhat in color. Spins a loose cocoon and trans- 

 forms in the earth.

Eyes naked, globose ; head not retracted sometimes with a tumescent 

 projection ; tongue strong ; thorax stout, vestiture hairy, forming a small 

 acute tuft behind collar ; abdomen of the usual form, distinct dorsal 

 tufts at base ; primaries with somewhat produced apices ; form much as 

 in Heliothh ; tibiae not spinose ; anterior sometimes with a claw at tip. 



The species belonging to this genus Mr. Grote catalogues as Pt/rrhia, 

 using Churiclea for two species, triangiilifer and peruana, which are 

 not congeneric with C. umbra. I cannot agree with him in this use of 

 the term, and prefer to use Charicfea as used by Lederer, regarding the 

 species so referred by Mr. Grote as generically distinct, and, indeed, as 

 scarcely belonging to the Heliothith, the prominent inner angle of prim- 

 aries in peruana, and, indeed, the entire appearance of the insect ally- 

 ing it much more nearly to Plusia than Heliothis. 



Of the three species described as Pt/rrhia, I know only two; stif/a, 

 Grt., and illiterata, Grt., are unknown to me. Illiterata by-the-bye has 

 disappeared from the list, and the why and wherefore thereof I have not 

 as yet ascertained.* That leaves of the species catalogued by Mr. Grote, 

 Exprimens, Wlk., and Angulata. Grt., both of these are varieties of one 

 and the same species, viz. : 



* Since the above was written I find that the species has been referred as a 

 synonym of Orthosia auranliago, Gn.
