Unlike any descril)ed American form, with the usual transverse 

 golden fascia replaced by the central longitudinal golden spot. 



I hope shortly to be able to finish a revision of the American species 

 of this genus wdiich has long been in manuscript. In the meanwhile 

 it will be wadl to call attention to the fact that the species desci'ilx'd In' 

 BeutenmiiUer from Florida as C floridanella and redescribed from there 

 by the writer as C. nigrap^incteWt as mentioned before" is the same 

 species which Lord Walsingham had alread}^ described as Coxuuqdcryx 

 fernaldella^ as the type of this species in Professor Fernald's collection 

 proves. This species seems to occur all along the eastern Stjites; I 

 have taken it in the District of Columbia and have received it from 

 Dr. William Dietz, collected at Hazleton, Pennsylvania.
