46 THE LEPIDOPTERIST 



usually very plentiful at "sugar. Here are included 

 the Zylinas, Agrotis, Acronyctas, Mamestras and allied 

 groups. I have taken over 500 perfect specimens of 

 these groups in one night's "sugaring" at Concord, 

 Mass. in the middle of October. 



For Catocalce collectors there seems to be a general 

 rule, which of course has exceptions, that seems well 

 to follow. The appearance of the various species 

 can be divided quite definitely into three groups as 

 follows : first appearing^, the oak feeders, followed by 

 the willow and poplar feeders, and last the hickory 

 feeders. The groups overlap to some extent and such 

 species as C. badia, C. ultronia, C. antinympha being 

 found mostly during the middle period. 



A New Form of Catocala Sappho 



CaTOCALA SAPPHO FORM CLEIS FORM NOV. 



By Samuel E. Cassino, Salem, Mass. 

 This form of sappho is so dififerent from the type 

 described by Strecker that it deserves a name. In the 

 typical sappho the t. a. line is broad and black on the 

 costa but soon fades out and almost disappears, but in 

 Sylvia it is of a uniform blackness and very pro- 

 nounced. The t. p. line is much better defined than in 

 sappho, and plainly geminate. The sub-terminal line 

 is faint but fully developed. The scales on veins near 

 the outer edge are darker than in sappho. The reni- 

 form is composed of brown scales, surrounded by a 

 line of white scales defined by black. There are more 

 dark scales between the reniform and the t. p. line 

 than in sappho. Sub-reniform black on the inne side 

 but open on the outside. The line of brown scales 

 which follows the t. a. line is well defined and darker, 

 almost black on the costa and the inner margin. There 

 is a dash of brown scales above vein 1. b. extending 

 from the t. a. line to the t. p. line. Terminal lunules 

 darker than in sappho. The under side of the wings 

 dififer from sappho in having the white bands consid-
