paler central line. Secondaries 9 white, the veins dark marked. 

 Beneath white, primaries somewhat smoky, and with a trace of an outer 

 line. 



Expands 33""" ; 1.32 inches. 



Habitat. — California (Neumoegen). 



A single female only of this pretty and sharply defined species is at 

 hand. It has all the appearance and structural peculiarities of the tes- 

 sellata group. The white secondaries of the 9 ally it with 2JaUipcnnis, 

 while the maculation of primaries is much more like albipennis, or even 

 insignata. Some clearly marked specimens of tessellata resemble this 

 species, but the white secondaries are always distinctive. Had the 

 specimen been a male the white secondaries would not have been so 

 important, as the female may have dusky secondaries when those of the 

 S are white. The reverse, however, is never the case within my experi- 

 ence. 



Carneades pallipennis Smith. 



1887. Smith., Proc. U. S. Nat. Mus., x, 461,. Agrotis. 



Pale whitish gray, i^owdered with fuscous ; terminal space darker. 

 Transverse lines geminate ; t. a. slightly oblique and moderately curved 

 between veins ; t. p. crenulate, outwardly augulate on costa over cell, 

 then obliquely in a rigid line to internal margin. S. t. line denticulate, 

 narrow, pale, marked by a preceding dark shade. A very faint median 

 shade. Claviform obsoletely indicated. Ordinary spots moderate, nor- 

 mal in shape, incompletely outlined ; cell between, dusky. Secondaries 

 pure white. Beneath white; powdery toward apices: an incomplete, 

 imperfectly marked common line. Head and thorax coucolorous. 



Expands 31-33™™ ; 1.25-1.30 inches. 



Habitat. — Colorado, northwest British Columbia. 



There is no difldculty in recognizing thi« species once it is referred to 

 this group, but it might with almost equal justice have been referred to 

 messoria and associated with orbicularis. The black shading on cell is 

 indefinite; the median shade more or less evident on each specimen. 

 It might even have been referred to thQ pitychrous group without doing 

 violence to the arrangement. In truth this is one of those unfortunate 

 forms that tit nowhere and has no decided characteristics. It is one of 

 those species that there is a temptation to utterly^ destroy to get rid 

 of it. 



A 9 specimen from British Columbia, received since the above was 

 written, has the median shade less marked, the darkening of the cell be- 

 tween the spots distinct, and a black spot before the orbicular. The 

 reference to this group is therefore fully justified.
