solete, it is the lower part that is first lost and the upper portion is present. 

 In no case are all the transverse lines entirely wanting. 



In the second series some one of the transverse lines always comes 

 below the submedian pale streak. This is invariable. Sometimes the 

 outer two lines join at the streak ami a single spur crosses the line to the 

 margin or at least to the internal vein. The basal band when pres< nt, 

 also crosses this streak. If a line is partly wanting, it is the upper por- 

 tion, while the lower portion is distinct. In all specimens I have seen, 

 some one of the lines, usually the outer, is distinct. 



To the first section containing species in which the transverse bands 

 do not cross the streak, belong rectilinea, anna, with the variety perse- 

 phone, virgo and saundersii, and possibly some of the species unknown 

 to me — for I want to say right here that I have made no attempt to classify 

 the species not known to me either autoptically or through a figure ; this 

 paper being intended to be suggestive merely. 



Rectilinea differs from all of these in having the transverse line rigid, 

 and even — rtstmbWng phyllira very strongly indeed in the heavier macu- 

 lation, and differing only in the pale veins. 



The other species all have the transverse lines more or less irregular 

 and bent, never rigid, and except the outer they are quite generally more 

 or less wanting. 



Virgo is the largest of these species, with red underwings, and with 

 the latter maculate outwardly and basally. 



Parthenice, the saundersii of Mr. Grote, is very closely allied, but 

 smaller, and so far as I have found, without the basal maculation of 

 secondaries, the outer spots being closely as in virgo. I believe with Mr. 

 Hulst that Kirbv's species referred to this smaller form and not to virgo. 

 Mr. Stretch's intermedia is not a synonym of this species as Mr. Grote 

 classes it, but belongs to the next section. 



Virgo appears very rarely with yellow secondaries. Anna has black 

 secondaries, while its variety, persephone, has them yellow with black 

 outer margin, sometimes broken into spots, and connecting with the black 

 form by an infinite series of variations. Though first described, anna is 

 much the rarer form. 



The second of the sections, with the transverse band coming below 

 the longitudinal stripe contains intermedia, of which stretchii Grt. , is a 

 synonym, dahurica, edwardsii, achaia, and possibly complicata. 



Intermedia is the largest of these, and rather a larger-winged form in 

 appearance, with a few outer spots on the red secondaries. Stretchii is, 

 the form in which the basal band is distinct, but in a large series of Texan 

 specimens this feature is seen to be a very gradually evanescent character, 

 all sorts <>l intergrades being found. In fact, the form figured by Stretch
