GENUS LIMENITIS 179 



dary, and ought to be taken at Yuma, and along the Colorado 

 River, but there are no notes of any such capture ; yet it may be 

 looked for at any time. 



The sexes, as in Ccenia, look much alike, and are to be deter- 

 mined same as Coenia. The figure is a male. 



Genus LIMENITIS. 



The species of this genus are all of medium or large size, and 

 mostly black in color, with white or yellow markings. The an- 

 tennae are nearly as long as the body, the club being an insensible 

 enlargement ; the wings never have any ocelli, nor any tails. The 

 eggs are placed singly on the tip of the leaf, and the larva lies hid- 

 den along the midrib, during its early stages. 



The sexes are much alike, and determination is difficult until you 

 become acquainted with the several features which help in the 

 matter. 



236. Limenitis Arizonensis. 



No figure. 

 This is a variety of the Eastern Limenitis Astyna.x : the whole 

 upper side of the wings being bluish-black, even the submarginal 

 white spots seen on Astynax being suffused or over-washed with 

 the ground-color, so that there is scarcely any white to be seen. 

 The form known by this name is rare, and is not known outside of 

 Arizona that I know of, so that it has but little interest for West 

 Coast people. 



237. Limenitis Weidmeyeri. 



Plate XXIII : Figure 237. Northern Arizona, July, 1890 ; 

 F. Stephens. 



Weidmeyeri inhabits the countries of the Great Basin, all the 

 States between the Rocky Mountains and the Sierra Nevadas, 

 from Canada to Mexico : but it is not seen to the west of the Sierra 

 Nevadas in the States of the Coast, proper ; unless at the eastern 

 base of the range, in Southeastern California, or in the semi-desert 

 regions of Eastern Oregon and Eastern Washington. 



As in the previous species, the sexes look much alike, and are 

 to be determined in the same way.
