In the male by having the greater part of the upper surface 

 of the pterostigma of the front wing blue, and by the shape of 

 the terminal abdominal appendages, especially the hook-like 

 form of the superiors (viewed from above, PI. XI, fig. 6). 



In the orange female by the presence of a black band on the 

 humeral suture (absent in Ramburii orange 9 )> and the pre- 

 dominance of black on the dorsum of 2 and 3 (orange in verticalis 

 orange $ ). 



The nearest ally of Kellicotti is verticalis Say.

 By Harrison G. Dyar. 



Seven years ago an article appeared in this magazine under 

 the above heading, in which this species was referred to the 

 synonymy. No one has questioned the conclusions there set 

 forth; but about a year ago when rearranging the Cossidae of 

 the National Museum I found both sexes of Cossula magnifica 

 Bailey. The sexes are exactly alike as in Dr. Bailey's figures. 

 This at once upset the accepted synonymy ; but I was not able, 

 until very recently, to correct the matter fully, as I had no speci-

 will have to be restored to our lists. Mr. H. Edwards relied on 

 Abbot's unpublished plates for authority in associating these 

 moths as sexes of one species ; but in these same unpublished
