Treitschke's species of Herminia. It seems to me we may do jus- 

 tice to all their observations and restrict Herminia to a genus of 

 which Herminia tentacularis would be the type. Schrank's term, 

 Polypogon, it must be remembered, is preoccupied and must be aban- 

 doned. Hiibner's term, Paracolax, is restricted by Stephens to the 

 European derivalis, nemoralis and tarsicrinalis. Stephens' restric- 

 tion of Macrocliilo, Hubner, to the European crihralis, should appar- 

 ently be followed. For our species, that appear to me congeneric 

 with the European included by Lederer in his Group A of Zanclog- 

 natha, I use this term. There is an agreement in the curvature of the 

 second palpal joint, the fore tibiae are provided with a fan-shaped 

 brush capable of expansion, the species are rather heavy and the pri- 

 maries seem narrow with straighter external margin than usual. Our 

 North American species are Zanclognatha laevigata (Grote), 

 ZANCLOGisrATHA CRURALis (Guenee), Zanclognatha marcidil- 

 INEA (Grote), Za]S"CLOGN"Atha obscuripennis (Grote), and Zax- 

 CLOGNATHA ocHREiPENNis (Grote). For Guenee's Herminia mor- 

 bidalis, I propose the term Chytolita,'' Chytolita morbidalis 

 (Guenee), difiFers from Zancloguatha in the straight second palpal 

 joint, and from Pechipogon in the shape of the wings and neura- 

 tion as indicated by Guenee. It was a common species about Phil- 

 adelphia and has been reported to me by Mr. J. A. Lintner as taken 

 near Albany. It is easily recognized by the guttate subterminal 

 line. 



Eather resembling Chytolita in general appearance, but in reality 

 nearer to Zancloguatha in the shape of the second palpal joint, is 

 Herminia 2)edipilkd is Guenee, for which I propose the generic term 

 PiTYOLiTA." As to how far this may be found to agree with any of 

 the European species contained in Lederer's second Group of Zan- 

 cloguatha, I am not clear, but in the incomplete brush on tlie fore 

 tibiae, the frailer form and broader wings, it is easily separated from 

 our species that I have arranged under Lederer's genus. There 

 remains but to be noticed two species already described by myself 

 under the name Philometra, and which, in some respects, have a 

 resemblance to the European Hermiuia tentacularis. These two 

 species just alluded to as under Philometra, agree remarkably in
