THE CANADIAN ENTOMOLOGIST. 



193 



collections are increased throughout the country. Without doubt, when 

 we shall be thoroughly conversant with the immature stages, our know- 

 ledge of the species will be more perfect. Our collections containing only 

 the perfect stages, the forms are clearly recognizable. Mr. Grote has 

 recently arranged the species of this group in the Collection of the Buffalo 

 Society of Natural Sciences as follows, and a species named for the first 

 time is contained therein. The following classification contains our North 

 American species, one of which (sappho) is unknown to me. 



Gen. Catocala Schrank. 



Group I, Mormonia Hiibner. 



Sub-group I (fringe of secondaries white). 



8. 



C. epione Driiry. 



C. lacrymosa Guen. 9. 



C. sappho Strecker. 10. 



C. subviridis j^(;?r7-'^. 11. 



C. agrippina Strecker. 1 2. 



C. viduata Qtien. 13. 

 C. desperata Guen. 



C. xQ.\.Q,c\2iGrote. 

 C. flebilis Grote. 

 C. ulalume Strecker. 

 C. Robinsonii Grote. 

 C. obscura Strecker. 

 C. simulatilis Grote. 



Sub-group II {fringe of secondaries blackish). 



14. C. Levettei Grote. 17. C. insolabilis Guen. 



Syn. C. Judith Strecker. 



15. C. Angusi Grote. 18. C. tristis W. H. Edw. 



16. C. residua Grote. 



It would seem best to follow this arrangement of the species. In the 

 second sub-group the apices of secondaries are not touched with white or 

 scarcely so in Lroettei. In tristis the white apical patch is quite evident. 



C. siibviridis, n. s. 



^ . Allied to agrippina. Differing by the fore wings being shaded 

 with dark silky green. Lines black, evident, accompanied by white 

 scales, evident on internal margin. The brown shades of agrippina are 

 wanting. Sub-reniform, detached, small; subterminal line white and rather 

 evident. Beneath like agrippina, but the white bands are narrower. 



Expanse 3^ inch. Habitat, Dallas Co., Texas, Boll Coll. One 

 specimen. Possibly figured as a var. of agrippina by Strecker.
