[.l/.w]. He says 1. c. ' * * traverse aw uiilieu par une bande * * * (jni

 ****.' We cannot say of the latter species [^4^so] that this band 

 blends perfectly into the design of the ground, for in Cramhis \_Aho'\ 

 the middle band is always distinctly separated from the ground color, 

 while in dark colored specimens of Oeno the black marbling certainly 

 covers band and ground color so uniformly, that it becomes difficult to 

 distinguish the former in its course" (pp. 208, 9). 



In regard to these various points of distinction which are now clearly 

 set forth in opposition, I will bring forward the following considera- 

 tions. I have under examination a S of C Also, marked Cramhis by 

 Moschler himself, as I am informed, which agrees well with the dis- 

 tinctive characters of G. Also as he gives them. I have also undoubted 

 specimens of C. Oeno from Labrador, in one of which no trace what- 

 ever remains of the middle band upon one wing, and the scarcely dis- 

 cernible outline of its outer limit upon the other, which has also pro- 

 minent black spots upon the border of secondaries, some of the ner- 

 vures delicately flecked with white, and the markings of the under 

 surface showing through upon the upper side with almost perfect dis- 

 tinctness; it measures, however, fifty millimeters in expanse of wings. 



Xow between these two I have not before me every shade of differ- 

 ence, but I believe that a larger number would show it unquestionably, 

 for in the comparatively few which I have, I find those which I can- 

 not reasonably place with one rather than with the other, which have 

 the outer border of the band varying so much that in some I find it 

 agreeing with C. Also in its abrupt arching of the central portion, 

 sometimes bent at the second nervure and not at the sixth, sometimes 

 at the sixth and not at the second, sometimes with a continuous curve, 

 and in all these cases sometimes with crenulations, sometimes without, 

 though the continuous curve is generally accompanied by crenulations, 

 and the bending of the border at the second and sixth nervures to form 

 the arching of the central portion is usually unaccompanied by crenu- 

 lations ; the flecking of the nervures with white appears to be equally 

 unimportant. The specimen marked '' Cramhis" by Moschler, which is 

 an undoubted C. Also, shows a portion of the nervures delicately flecked 

 with white, while an unquestionable C. Otno with nearly uniform black 

 marbling shows none at all, and so it varies indiscriminately through 

 the series ; and further, although those which approach most nearly to 

 the description of C. Oeno as given by ^Moschler do generally have 

 black spots on the border, I have before me two individuals with uni-
