and position of the uncas, the claspers and harpes, as well as in 

 other parts, quite enough to entitle it to specific standing. Nigro- 

 angidata, our large western species, varies somewhat in markings, 

 but not nearly to the extent of lirnitaria. It is quite easily sepa- 

 rable as a species, and the genitalia bear out this assumption. 

 Drawings, in part, of the genitalia of each of these species are 

 here presented to evidence the difference between them ; and it is 

 a very desirable thing to know, for I must confess that I have 

 always been uncertain as to the exact relation between the forms 

 of lirnitaria and anguilineata. 



Viridata, a rather rare species in collections, was tentatively 

 retained in the genus Nyctobia (Can. Ent., vol. 39, p. 371) by the 

 author. While agreeing with the requirements of that genus in 

 many respects, there remained the great length of its palpi and 

 different style of markings, features which did not assimilate. 

 The drawing here given of its genitalia would indicate a positive 

 generic separation. There being none that it can enter, though 

 close to Lohophora, I have restored for it in my own collection, 

 the genus Agia Hulst, of which under the name of ehorata, it 

 was made the type. In the paper referred to, I also placed 

 vernata Pack, as a synonym of anguilineata Grote, but the sole 

 type of vernata, now at Cambridge, is a much worn example of 

 Cladara atroliturata Walk., and it will be noted, his original de- 

 scription (5th Rep. Peabody Acad., p. 56) might easily apply to 

 it. He had then but a single male and female before him, but 

 in the " Monograph " he cites three males and three females, his 

 figure (plate 8, Fig. 13) indicating a form of lirnitaria. In any 

 event it is a synonym, and since a type, whether original or not, 

 is existent, it would best stand under atroliturata.
