not exactly like that of either of the species in question, although it 

 more nearly resembles calanus; the color of the under surface in no 

 way resembles that of Edwardsii, and is precisely the same as calanus] 

 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; the mesial band consists of 

 a continuous series of quadrate spots, whose connection is so close as 

 to be generally indistinguishable (an unfailing mark of calanus) , but 

 edged with white scales on the inner side, as distinctly as on the out- 

 side, excepting on the primaries of the male — which rarely or never 

 happens in either species, and in one no more frequently than in the 

 other ; this sexual distinction is, however, that of calanus ; the orange 

 lunule of the under surface is given rather as it usually occurs in 

 Edwardsii than as in calanus, but is not very uncommon 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 Edwardsii rather than calanus; 

 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. 



Laying as they do, too exclusive stress upon the presence or ab- 

 sence of the orange patch near the anal angle of the upper surface 

 of the secondaries, they have also come to an erroneous conclusion 

 concerning Boisduval and LeConte's plate, which, bad as it is, can 

 certainly only represent calanus. 



The specimens in the Harris Cabinet all belong to Edwardsii. 



The synonymy of the two species will then be as follows : —
