Fabricius has taken the male of this Vanessa for the C-aurcum of Linnfeu>, 

 and he has made of the female a separate species under the name of Papilio in- 

 ter rogationis. 



It has between two, and two and a half inches of breadth. The upper sur- 

 face of the superior wings is fulvous, with seven or eight unequal black spots, 

 and the posterior border of an obscure brown. The upper surface of the sec- 

 ondaries is of a bluish-black, with the base ferruginous. The under surface of 

 the male is of a wood gray (gris-bois) undulated and variegated with brown ; 

 the under surface of the female is brown and lightly glossed with whitish-green, 

 especially on the secondaries, on wHich the disc presents in both sexes, a silver 

 spot in form of an interrogation point or interrupted C. There is besides toward 

 the posterior border of each wing, a row of black points. The body is black a- 

 bove, with some greenish hairs on the thorax; the antennseare brown, with the 

 anterior third of the club whitish and the rest black. From Virginia and the 

 neighboring States. 



The description iu the above paragraph is applicable to umhrosa, 

 and if unqualified, would lead us to refer it to that insect. The "alis 

 anticis /a/ra^/.s," however, forbids such a reference, and indicates its 

 having been drawn from some Grapta which as yet has no place in our 

 collections, or, as is more probable, from Abbot's figure of C-aiireum, 

 to which it suspiciously conforms, and which is not our umhrosa. In 

 C-aurcum of Abbot, the primaries are conspicuously falcated; in um- 

 hrond, they are never falcated. The two differ otherwise materially in 

 outline, and in the extent of the black shading of the posterior wings. 



In the Supplement to vol. ix, Enc. Method., page 819, n. 15 (du- 

 plicata), (loLlart has amended his infer rogationis, so that it conforms to 

 the species as generally accepted at the present day. It is as follows : 



Vanessa P. interrogationis. . 



It has from two to two and a half inches breadth. The upper side of the wings 

 is fulvous, with eight or nine unequal black spots on the superiors, and three 

 on the inferiors. The outer margin, which is of a ferruginous more or less in- 

 tense, with a transverse series of yellow spots, is bordered exteriorly with ash- 

 blue. 



The under side is of a blackish brown or dead leaf color, more or less shaded 

 with gray violet, with a silver spot in form of an interrogation point or inter- 

 rupted C on the disc of the inferiors. There is also toward the terminal border 

 of the four wings, a transverse row of black points, in part sprinkled with bluish. 



The female, ordinarily larger than the male, has the origin of the costa be-
