is in residua. The latter . species may be known by the deeper tone of 

 primaries from base to subterminal line. The fore wings in Angusi are 

 not dusky as in residua, simidatilis and obscura, but slightly greenish gray, 

 not very bright. 



Catocala mira Grote. 



This form is mentioned by Prof. Snow. It is as large as polygama, without 

 determinate greenish or brown shades on fore wings. Lines black; t. a. more 

 denticulate than in the three allied forms, crataegi, polygama, pretiosa. The 

 pale shade over the sub-reniform from costa is without dark irrorations, 

 distinct. The primaries are pale, more gray and smoother than in con- 

 trasted forms. The hind wings are of a deeper yellow, bands very 

 similar, while the internal margin is notably free from dusky hair and 

 scales. Beneath the black band is broader than in its allies. I do not 

 think that any of these four forms now intergrade. They may be con- 

 sidered as distinct " soecies/' 



Catocala eerogama, var. Bimkeri. 



This form of eerogama, received from Mr. Robert Bunker, has the 

 band on secondaries extremely narrow and the yellow basal shade entirely 

 lost. On the fore wings the median space is deeply brown tinted, setting 

 off the white sub-reniform. 



Catocala habilis, var. basalis. 



Differs from the type in the presence of a basal black ray on primaries. 

 On hind wings the median band is broader ; the fringe is medially scal- 

 loped in black. The terminal inflection of the t. p. line on primaries is 

 deeper and more distinctly black marked. The form seems to be a little 

 larger than the type. Specimens received from Mr. Robert Bunker, taken 

 about Rochester, N. Y. 



In studying the black-winged series we may divide them by the fringes 

 in sub-groups.
