GEIROCHEILUS I. 



a little dusky on upper side ; palpi whitish, the long hairs in front and at tip 

 brown ; antennjE brown, grayish towards end, gray below, club yellow. (Figs. 

 1,2.) 



Female. — Expands from 2 to 2.3 inch. 



Similar in color and markings to the male. (Figs. 3, 4.) 



Tritonia was first made known by Mr. H. VV. Henshaw, of the Wheeler Ex- 

 pedition, 1873, a few examples having been taken among the White Mountains 

 of Arizona. Later, I received others from near Prescott, Arizona. Neither Mr. 

 Morrison nor Mr. Doll, in their collecting trips to that region, fell in with this 

 species, nor was it seen by Mr. Wright or Mr. Baron. It probably is confined to 

 special localities. Of its habits I know nothing, but Mr. Baron writes me of the 

 allied species, G. Pcdrobas, which he took in Mexico, that it flies at an elevation 

 of 6,000 feet, among pine and oak timber, and a thick growth of coarse grass. 

 Its habits may be similar to those of Satyrus Pegala, in south Georgia. 



These two species constitute the genu.s. I have a pair of Patrobas, sent by 

 Mr. Baron. It is a considerably larger insect than the other, in general similarly 

 marked. The white spots are smaller, the crenated marginal band much wider, 

 occupying fully one half the whole ferruginous area, the ocelli below and their 

 pupils are larger ; on the fore wings there is a lilaceous sub-ajjical nebula, not 

 found in the other ; on hind wings the variegated area is narrower, more red, 

 less lilac, and becomes obsolescent on the upper half or third to costa ; and the 

 spots of the yellow series are smaller and more regular.
