The synonomy of Huebner's species is as follows : 

 Argyria nummidaUs Huebner. 

 Catharylla fuscipes Zeller. 

 Urola subaenescens Walker. 



The described species of the United States may be separated by 

 means of the following table : 



Fore wings snow-white with an satin luster and an orange colored band across the 

 middle : hind wings pure white. 



Cross-hand of fore Avings connected with the terminal line by a 



stripe of the same color on the inner margin, pulchella, Walker 



Cross-band of fore wings not connected with the terminal line auratella, Clem. 



Fore wings snow-white with satin luster without orange colored bands across the middle. 

 Fore wings with brown dot on the middle of the inner nborder 



[some times wanting]: hind wings pure white nivalis Drury. 



Fore wings with an orange colored stripe on inner border from, the 

 angle to the base broadest outwardly ; hind wings yellowish 



white nummulaUs Uueb. 



Fore wings silvery white with two ferruginous dols on the costa and one on the inner 

 border, hind wings yellowish white ruflsignella Zell. 



Clemens' description of auratella (Proc. Phil. Acad. Sc. 1860 

 page 204) is somewhat faulty and does not quite agree with his type. 

 Instead of saying that the orange yellow band is somewhat produced 

 along tlie inner margin towards the anal angle, he should have said 

 towards the haae. of the wing. One would suppose without seeing 

 his type, that he might have had Walkers pulchella before him Avhen 

 he wrote his description. 



The date of the publication of Zeller's paper mentioned above, 

 should be definitely determined since it was in the same year with 

 Walker's Catalogue and both papers contain descriptions of species 

 from various parts of the world and as shown above, some species 

 have been described by both authors under different names. 



Walker's Catalogue Lej)idoptera Heterocera Part. 27, which in- 

 cludes his Crambites, bears the date of March 2, 1863, while Zel- 

 ler's paper bears only tlie date 1863, but Dr. Hagen has written to 

 me as follows : "Zeller's Chilonid et Cramb. was a part of the pro- 

 gramme of the King's Eeal School in Meseritz, inviting people to 

 the public examination which occurred on March 30, 1863. Accord- 

 ing to the laws and customs such invitation Programmes are sent 

 around some weeks before the date. Zeller's Programme was prin- 

 ted certainly before March."
