CAMPOMETRA MIMA Harvey. 



The most common of tlie species, and as they run, very sharply defined. 

 The transverse anterior line is gemiuaie, both defining lines black, rath 3r 

 widely separated, the intervening space dusky so as to form an evenly 

 outcurved dusky band. The transverse posterior line is also black, 

 well marked, and squarely exserted beyond the reniform. A yellowish 

 or reddish brown shade lightens the wing and dominates the impression 

 gained by an ordinary examination of the species. 



The middle tibite are unarmed and in the male have a very heavy 

 scale tuft; but there are no hair pencils. 



Twenty specimens are under examination: San Diego, Texas, April 

 26, May 25; Bastrop County, and other Texan localities; Florence, 

 Tucson, Catalina Springs April 11, Oracle, July 21, and other locali- 

 ties in Arizona. The tendency in the variation is to a more indistinct 

 maculation. 



CAMPOMETRA FRATERNA, new species. 



Resembles mima in all essential characters and differs from that 

 species in the powdery,' uniform ashen gray primaries lacking the 

 brownish shadings, and on which the maculation is only feebly writ- 

 ten. The transverse anterior Ime shows no tendency to band and, 

 while the other lines and shades of mima are all traceable, none are 

 well marked. In the structure of the middle tibiie of the male the 

 species is like its ally. 



Type.— No. 4313, F.S.N.M. 



I have six specimens, five of them females, from Death Valley (April), 

 Oracle (July 7), and Catalina Springs (May 5), Arizona. All are from 

 the II. S. National Museum, collected by Messrs. Koebele or Hubbard 

 and Schwarz. 



CAMPOMETRA MINOR, new species. 



Smaller than mima throughout, few of the specimens exceeding and 

 some not reaching 26 mm., or a trifle over 1 inch, the primaries even, 

 powdery gray, none of the markings well written, though so far as 

 traceable, similar to mima. It is a slighter, narrower winged form than 

 fraterna, w^hich equals mima in average size and has the primaries 

 more squared. 'No male of this species has been available. Of the 

 five females four are from the Hulst collection, probably taken near 

 Tucson Arizona, and one is from Catalina Springs (April 11), taken by 

 Mr. Schwarz. The latter has a white shading over the reniform, 

 extending beyond the transverse posterior line almost to the subter- 

 minal line, the edges of this shade being indefined. The smoky margin 

 of the secondaries is narrower tiian in the allied forms and there is less 

 tendency to a banding. 



Type.— No. 4314, U.S.N.M.
