The European satellitia, varies in a similar manner. Our species 

 seems to be more intensely colored than the European, but other- 

 wise resembles it closely. 



4. Scopclosoma Walkeri. 



Dicliagramma Walkeri, Grote, Proc. Eut. Soc. Phil., 1804. 



IlaMtat, Canada (Pettit); New York; Buffalo (coll. of this So- 

 ciety). On account of the long and narrow primaries, with uneven 

 fringes and external margm, I refer this species as congeneric with 



5. sidus, differing in these characters from Cerastis. The $ moth has 

 been taken in this vicinity in March, during cold Aveather (about 

 maple trees, sucking the sap), by my friend David F. Day, Esq. 

 The sj^ecimens were in good condition but had evidently hyberna- 

 ted. Lederer remarks that the hybernating specimens of Cerastis 

 and Scopelosoma noticed by him were all females. The reniform 

 varies as in sidus, being sometimes white, again ochreous, usually 

 less distinct than in sidus, but again specimens occur, in which the 

 two accompanying white dots are readily perceivable. In its dusky 

 and ochreous colors this species is very different from sidus. The 

 median shade in Walkeri, is straighter, below the reniform, than in 

 satellitia, where it is waved, and the obsolete denticulate transverse 

 posterior line is also a little straighter in its general course. In gen- 

 eral color Walkeri varies from ochreous to dusky olivaceous brown, 

 while the other two species are rich reddish or purplish brown, and 

 so, much deeper and more intensely colored. The marginal pale 

 points in satellitia, following the finely waved terminal line, are not 

 perceivable in Walkeri, which is the more roughly scaled species. 



5. Plusia Putnami, Grote, Plate 4, fig. 3 ^ . 



I have, since describing this species, received from Europe the true 

 festucae, corresponding with Engramelle's figures, 585 a-f, and I find 

 that the North American species I have used for comparison with 

 Putnami, is distinct h'om. festucae. Plusia Putnami, differs from the 

 European festucae, in the much smaller aureate median spots and 

 the different shape and upward extension of the first of these, and in 

 the more rosy fore wings which want the dark ground color and discol-
