were 8 males and 15 females that were separated out as representing 

 the true lunifera and which gave opportunity to study local variation. 



In ground color the variation is from very light creamy gray to 

 a rusty brownish gray: the latter more general in the specimens from 

 the southwest (Texas), which are also notably larger. Galbanuta 

 Morrison is based on one of the neatly marked gray forms. 



The difference between the sexes is not uniformly marked and it 

 is not always possible to separate them from the wing characters 

 alone; nevertheless, as a rule, there is more gray powdering in the 

 terminal space in the males than there is in the females, and in size 

 the female usually exceeds (he malt*. 



Typical specimens have no sharply defined lines or marks and the 

 wings seem to be crossed by a mass of slightly undulating dusky 

 lines. From that point variation runs to forms which it is not easy 

 to differentiate from some forms of lunifera. 



In structure of legs and in the male and female genitalic characters 

 I can find no substantial differences; in fact, the northern gray and 

 southern red form- actually show more divergencies than do the 

 typical lineosa and lunifera. Yet for reasons already given I have 

 preferred to hold the species distinct.

Ground color rusty yellow or leather brown, more or less washed 

 with gray. Head usually deeper brown. Collar sometimes steel gray 

 just below tip. Thorax with three vaguely marked transverse dull 

 gray bands which are often obsolete. The posterior tufting is unus- 

 ually thick and the patagia are divergent and alate in well preserved 

 specimens. Dorsal tufts of abdomen very small, and in flown exam- 

 ples are more often altogether absent. Primaries rusty in appearance, 

 more in' li sss strigillate or powdered with dark brown or even blackish 

 scales; sometimes arranged so as to form a series of vague discal 

 transverse lines. Basal space usually a little darker, a narrow pale 

 line separating off an outer band which serves as the t. a. line and 

 may be itself outwardly edged with paler scales. Orbicular a small 

 black dot. visible in most specimens. Reniform narrow, upright, a 

 little lunate, small or moderate in size, dusky, usually not outlined, 

 but sometimes edged with rusty or yellowish scales. The t. p. and s. t. 

 lines are united for most of their course, and between vein and the 

 inner margin there is an even narrow yellow line, outwardly bordered 

 by a rusty brown line. This forms an obtuse outward angle between 

 veins ."» and -[. and above vein 6 it divides, the t. p. line running 

 obliquely inward to the costa, while the s. t. line continues its course a
