on both wings. The red spots, too, are more numerous, those of 

 the anal angle and the base of the costa of secondaries being 

 wanting in Mr, Edwards' figure. As the present form, however, 

 comes from nearly the same locality as the type from which that 

 figure is taken, it may ultimately prove to be an extreme variety 

 of P. Eversmanni. It is, however, so distinct to be considered 

 for the present as a separate species. 



Parnassius Hermodur. n. van 



2 A remarkable variety of P. Sviinthc2ts Dbly., which ap- 

 proaches very closely P. Corybas, Fisch, from the Altai. The 

 whole upper surface of the primaries is of a smoky black hue, 

 slightly transparent, the usual bands being lost in the ground color 

 of the wing. In this respect it nearly resembles P. Corybas, but 

 the latter, as well as two red spots near the costa, has also another 

 near the internal margin, which is absent in the present form. 

 The red spots of secondaries are nearly the same in both, but in 

 P. Hertnodur there is a trace of some red scales near the anal 

 angle, which is wanting in P. Corybas. The black sub-marginal 

 lunules of secondaries are also much more strongly marked in P. 

 Corybas than in P. Hermodur, and the wing is whiter and more 

 opaque. On the other side the resemblance is more apparent, the 

 red spots on the costa, and that between the sub-costal nervures 

 having white centres in both forms, while those of the base are 

 wholly red, and alike in their color and arrangement. The present 

 insect is smaller than its ally, the expanse being only 2.30 inch, 

 while the pair of P. Corybas in my collection measure 2.65 inch. 



Southern Colorado. 



Type. Coll. Hy. Edwards. 



This extremely interesting insect was generously given to me 

 by my friend. Dr. James S. Bailey, of Albany. I have named it 

 after the son of Odin and Freija, and the Mercury of the Scandi- 

 navian mythology. 



DESCRIPTION OF FOUR NEW SPECIES OF MOTHS. 



By a. R. Grote. 

 (Read before the N. Y. Ent. Club, at the first meelbig in December, 1880.) 



Scepsis Edwardsii. n. sp. 



This form is stouter than fiilvicollis, with paler forewings and 

 approaches Echeta albipennis, H.-S. from Cuba. 



Forewings pale, slaty brown, with a whitish cast; the costal 

 edge pale yellow, which shade extends faintly within the edge, 

 from the middle outwardly, and obtains beneath, over apical third 

 of costa. 



Secondaries hyaline with broad smoky costal border, and narrow 

 smoky external edging. 



Beneath, primaries bluish black ; secondaries hyaline with bluish 

 costal border. 



Head behind, palpi, base of fore legs orange. Thorax, pale,
