 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 magnified 

 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- 

 men of slossonia: Hy. Edw. One has just been received collected 

 by Mr. H. Schwarz at the Rancho Hanover, State of Vera

 generically distinct, as the venation shows, and Inguromorpha 

 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 Abbot's unpublished plates for authority in associating these 

 moths as sexes of one species ; but in these same unpublished
