II. The transparency of the winces. Tender the note in the descrip- 

 tion of C. Aho, referring to a description by Boisduval. Mbschler says : 

 '' These words (leur transparence est telle, que Ton volt a travers tout 

 le dessin du dessous) certainly refer well to Oeno H. Sch., for I never 

 found in Cramhis (Also Bd ) the design of the under side of the se- 

 condaries appearing so distinctly on the upper side as is the case in 

 Oeno" (p. 208). Further on. under the description of the upper sur- 

 face of C. Oeno, he says : '' The secondaries are of a like color with the 

 primaries, the dusky marbling of the under side shines distinctly 

 through especially on the outer half of the wing" (p. 212). No refe- 

 rence is made to such transparency of the wings in C. Also. 



III. The design of the under side of the secondaries; the special dis- 

 tinctions insisted upon are : 



A. The coloration of the nervures. 



On this point, under the description of C. Also, Moschler says : 

 '•Nervures not flecked with white" (p. 209); and further on, '"the 

 nervures of the secondaries are not flecked with white on the under 

 side" (p. 211). Under the description of O. Oeno we find these words : 

 '• Nervures ** delicately flecked with white" (p. 211); and again, 

 " the nervures in all fresh specimens are rubbed with whitish and mar- 

 bled by the black of the ground color" (p. 213). "In worn speci- 

 mens" it is stated, among other things, that " the white flecking of the 

 nervures is wanting" (p. 213). In his comparison of Boisduval's plates 

 of C. Oeno and C. Also, he says^ furthermore, ■' the nervures in fig. 6 

 are flecked with white as Oeno always shown them, but Cramhis [i. e. 

 Also'] never" (p. 2U8). 



B. Spots on the hind border of secondaries. 



Under C. Oeno we find the ''border with black spots situated be- 

 tween the nervures" (p. 211). This refers to the under side. A little 

 beyond, describing the upper side of the secondaries, he says : " The 

 border is characterized by clustered blackish atoms, which form on the 

 nervures black spots situated on the white fringe, which in the 9 are 

 much more distinctly and broadly marked than in the S " (p. 212). 

 Returning again to the description of the under side of the same, he 

 mentions that " before the border the black condenses into spots which 

 are both established upon the border and also cut through the fringe 

 as well, whereby this appears more broadly dappled with black than in 

 the allied species" (p. 213); but he does not here tell us whether 

 they are situated upon or between the nervures; the former is the case 

 both above and below in the specimens before me. In his comparisons 

 of Boisduval's figures again, speaking of the under surface he says :
