Under side more decidedly brown ; the spots on primariefl repeated ; 

 the sub-marginal enlarged, mostly lunate; the extra discal also enlarged ; 

 the discal nearly as above; two spots in cell, one near arc, one near 

 base ; a third below the origin of lower branch of median ; shoulder 

 ferruginous ; secondaries have a sub-marginal series of yellow lunules ; 

 a broad yellow band across disk ; a narrow yellow stripe near base. 

 from costal edge to sub-median nervure; half-way between sub-mar- 

 ginal spots and discal band, a series of yellow points, tortuous, com- 

 mencing on costal margin near the band, crossing the wing in a 

 double curve, the last point being on sub-median interspace; these 

 marks vary from points to conspicuous spots, and sometimes are nearly 

 or quite obsolete ; in middle of cell a yellow point ; anal spot as above, 

 ferruginous ; the upper part of abdominal margin edged with yellow ; 

 a yellow patch on shoulder. 



Body above blackish-brown, below gray-brown ; legs ferruginous ; 

 palpi white in front, black above and at tip ; antennae fuscous, finely 

 annulated with white; club black above, gray below, fulvous at tip. 



Female. — Expands 2.1 inches. Similar to male ; in the only speci- 

 men examined, the fulvous patch at inner angle of secondaries wa.s 

 absent; below cell of primaries two white points. 



From several males and one female, taken at White Mountains. 

 Arizona, in 1873. by Mr. Henshaw, of Lieut. Wheeler's Expedition. 



I submitted one of these specimens to Mr. A. G. Butler for deter- 

 mination, and he informed me that two examples from Mexico were in 

 the British Museum collection, and that they were regarded by him as 

 a di.stinct species, allied to Lacinia and Hippodrome. 



Geirocheilas Tritonia, n. sp. 



Male. — Expands 2.3 inches. Upper side velvety, blackish-brown, 

 changing to brown on hind margin of primaries with an olivaceous 

 tint at apex ; co-stal edge of primaries near apex yellow-white ; be- 

 yond disk a transverse row of four white points, set in middle of the 

 upper discoidal and three next lower interspaces ; the last point some- 

 times wanting on upper side ; secondaries have a broad marginal band 

 of dull ferruginous, even edged within, reaching the margin on that 

 part of wing between sub-median nervure and the upper branch of 

 median ; beyond this last receding from the margin, but usually con- 

 tinued past the upper branch of sub-costal and gradually diminishing 

 to a point, sometimes, however, terminating squarely at the lower
