species to be here considered, since the inner discal band is here completely 

 macular; and though in T. calanus this band or row of dark brown spots is 

 also, but more faintly, edged inwardly by a white line, we may assume that 

 this inner edging, always fainter and sometimes wanting on the primaries (T. 

 calanus and T. falacer), always wanting on the primaries, and in one 

 specimen on the secondaries (T. inorata) is not sufficiently constant to afford 

 a specific character. While Harris' T. falacer cannot be referred to Theda 

 falacer, Godt. sp., as illustrated by Boisd. Lee, it is probable that his speci- 

 mens are to be referred to T. calanus rather than to 1. acadica. 



It may be here remarked that our conclusion as to Harris' specimens turns 

 out to be correct, for Mr. Scudder refers them in this same paper to T. 

 Edwardsii, which is the same as T. calanus nobis. 



Mr. Scudder further finds that the distinctive character found in the 

 orange spots of the upper surface of "the secondaries only to be of relative 

 value, since specimens of T. inorata have occurred with these spot§, and of 

 T. calanus without them, the reverse having been assumed by ourselves in 

 our former papers as the fact. It is, however, quite clear that these spots are 

 the rule with T. calanus, the exception with T. inorata. 



With respect to the synonymy of the two species to be separated, Mr. 

 Scudder differs remarkably from ourselves. 



He considers Hubner's figure of calanus, which agrees in both sexes with 

 our T. calanus in its slightly greater expanse as compared with T. inorata, 

 its more brownish color, and in the very distinctly orange spotted secondaries 

 above, as representing Thecla inorata, and this mainly from the character of 

 the extra mesial band. 



Mr. Scudder says : il The color of the under surface in no way resembles 

 that of Edwardsii (T 7 . calanus nobis), and is precisely the same as calanus 

 (T. inorata nobis) : a small orange spot painted near the anal angle of the 

 upper surface of the secondaries in both sexes, occurs more frequently in 

 Edwardsii, but is by no means absent from calanus." 



And further : " The orange lunule of the under surface is given rather as 

 it usually occurs in Edwardsii, than as in the calanus, but is not very com- 

 mon in the latter ; and finally, the sexual patch on the upper surface of the 

 primaries of the male is as in calanus. That the extent of the coloring is 

 faulty is shown by several features in which it exaggerates either species, and 

 only when doing so does it approach Edioardsii rather than calajius ; in all 

 features of pure delineation it resembles only calanus, so that there can be 

 no possible doubt that Grote and Robinson's inorata is the same as Hubner's 

 calanus. 



If Mr. Scudder is right, then the species he calls Thecla Edwardsii must 

 be called Thecla falacer, Godart. The question of the synonymy of these
