to be the least common of the species, albeit widely distributed, the 

 specimens before me coming from Illinois, Colorado and Texas. It 

 has been also recorded from Canada and thus has a range that will 

 probably carry it to the Rocky Mountain chain. 



Frater Grt., is the most common of the species. It is also the 

 darkest in color and always recognizable by the contrast between the 

 very dark steel gray primaries and the white secondaries. The macu- 

 lation is in black, and the lines are as a rule clearly written. There 

 is more or less black powdering and in some specimens a tendency to 

 darken the lower half of the median space. In the material before 

 me are specimens from Ontario, Winnipeg, Cartwright, Manitoba, 

 Aweme, British Columbia, Connecticut, New Jersey, New Hampshire, 

 Illinois, Iowa and Colorado. Texas has been included in the record, 

 so that this is probably the most widespread as well as the most abun- 

 dant of our species. 



Coloradensis Cram., is nearer like abrupta than like frater in macu- 

 lation, but has white secondaries, while the primaries are more or 

 less blotched with yellow and powdered with black. There is a dis- 

 tinct tendency to darken the lower half of the median space, and 

 some examples are very contrastingly marked. All my examples are 

 from Colorado ; Denver and Fort Collins being the specific localities 

 represented. 



Elbea Sm., is a very characteristic species which, because of the 

 black powdering along the veins and the reduction of the transverse 

 lines, has a peculiar rayed or strigate appearance. The ordinary spots 

 are much reduced and the reniform is narrow, upright and scarcely 

 defined. All the examples are from Deming, New Mexico. 



Pallula Hy. Edw., looks, at first sight, like an intensified colora- 

 densis, but it is still more blotchy, more coarsely and irregularly 

 powdered, while the reniform is not outlined at all and only the dark 

 filling remains. Even this is reduced in some specimens so that only 

 a little black powdering remains to indicate the inferior angle, while 

 in other cases two black spots mark its upper as well as lower por- 

 tions. Denver, Colorado, and Phoenix, Arizona, are the localities 

 represented in my collection. 



Cinderella Sm., is a dull powdery gray form, but very pale, very 

 even and the powderings not black nor contrasting. The ordinary 

 lines are not well marked and while almost everything is present, 

 there are no really black markings at all. The s. t. line is really the
