petita and duveiKi — show obvious or even striking genitalie differen- 

 ces. Ohiii(/n( is definitely known in the female only ; but seems so 

 obviously different that I hav^e no fear of its validity. Lucina, altua 

 and megarenn may be races of olivacea, or the first and second may 

 be one species differing from either olivacea or megarena. The mossy 

 green suffusion, which I consider characteristic of olivacea, may not 

 be so really ; but the material in my hands is the most complete 

 that has ever been assembled and it justifies ray course. A larger 

 material of bred forms may disprove three of my names as species. 

 I think they will stand as races. 



It should be said as a caution that faded and badly rubbed exam- 

 ples of olivacea lose their characteristic appearance to a considerable 

 extent. To be fairly comparable, material from all species should 

 be in equally good condition. 



The accompanying plates illustrates the male genitalia of all the 

 forms; it is not given so much to show actual differences as to 

 prove constancy of type. 

 Itlaniesira lucina n. sp. 



Practically all that is distinctive in this form has been already 

 noted. It is not a good species as I take a species now. It is not 

 a variety as that term is usually understood ; it is a race or form 

 differentiated to some extent from the parent type. The most obvi 

 ous characters are smaller size, somewhat less distinct maculation 

 and total absence of all mossy, greenish or yellowish powderings or 

 shadings. 

 I?Iaine!«tra altua n. sp. 



Tlie essential characters of this form have all been given. Prac- 

 tically it is the eastern species with all the color out. No mossy 

 or vellow, no red ; only a dull ash gray, somewhat powdery to dis 

 tinguish it readily from megarena, and a few leather brown scales in 

 s. t. space opposite anal angle. The female is a little more evenly 

 dark powdered than the male. The Utah series shows son)ewhat 

 more contrast, but in a peculiarly dead tinge. 



I have marked this new species; it is only a race — a geographical 

 race — an incipient species. The name may be considered a little 

 premature, and I am quite content to let it be placed in a subordi- 

 nate position. It is not a variety. 



Mainestra inei;arena n. sp. 



Ground color a dark asheii gray, tending to black or deep smoky. Collar with 

 a central black line, white tipped, sometimes gray dusted. Patagia' more or less 

 gray powdered. Primaries gray powdered, in the female very slightly, in the 

 male obviously so, but never contrasting. S. t. space gray, with a reddish tinge
