fication which allows us to speak unduly and depreciatingly of those who 

 studied these matters long ago. 



As with former groups, the North American Hadenini show a pre- 

 vailing affinity with the European fauna. The amount of divergence can 

 hardly be shown until all the species are carefully compared, but we can 

 be sure it will not outweigh the resemblance.

Sub-Family Arctiin.^. 



In the previous paper I explained the sense in which this term is 



used, and nothing further in the way of definition need be said on that 



head. 



Genus Crocota Hbn. 



1816 — Verzeichniss ; Samml, Eur. Schm., III., 254. 



This genus is in a sad state. It is almost impossible to identify species 



satisfactorily, and yet new species are constantly described. The matter 



has been further confused by Mr. Grote's persistent refusal to refer to Mr. 



Reakirt's species, for without referring them positively as synonyms to 



any species, he says he cannot believe that they refer to species different 



from those recognized by him, and therefore he ignores them altogether. 



This has had the effect of causing others to lose track of the descriptions 



which, poor as they may be, yet are necessary to be referred to. We 



know nothing at all as yet as to the range of variation in the genus, and 



species are based upon the most indefinite comparative features of colour 



and appearance. 



Using C. ferruginosa as subject : The head is free, rather small ; eyes 



large, somewhat prominent ; ocelli distinct ; vestiture scaly, smooth ; 



antennce of male with the joints marked, scarcely serrate, with fine lateral 



cilige, palpi moderate in length, straight or slightly drooping. Thoracic 



vestiture scaly. Legs closely scaled, posterior longest, the spurs normal 



— i. e., middle with one, posterior with two pairs. The tongue is rather 



short, but corneous and spiral. Wings proportionately wide and short,
