r66 ZOOLOGY— INSECTS. 



pulpi white in front, black above and at tip ; antennas fuscous, finely annu- 

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



Female. — Expands 2.1 inches. Similar to male. In the only specimen 

 examined, the fulvous patch at inner angle of secondaries was absent. 

 Below cell of primaries two white points. 



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

 in 1873, by H. W. Henshaw, of this expedition. 



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

 tion, and he informed me that two examples from Mexico were in the British 

 Museum collection, and that they were regarded by him as a distinct 

 species, allied to Lacinia and Hippodrome. — Edwards, I. c. 



GYROCHEILUS, Butler. 

 GYKOOHEILUS TRITONJA, Edw. 

 Gcirochcilus Tritonia, Edw., Trans. Am. Ent. Soc, 1874. 



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

 changing to brown on hind margin of primaries, with an olivaceous tint at 

 apex ; costal edge of primaries near apex yellow-white ; beyond disk a 

 transverse row of four white points, set in middle of the upper discoidal, 

 and three next lower interspaces ; the last point sometimes 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 submedian 

 nei'vure and the upper branch of median, beyond this last receding from 

 the margin, but usually continued past the upper branch of sub-costal, and 

 gradually diminishing to a point, sometimes, however, terminating scpiarely 

 at the lower branch of same nervure ; through this band runs an indistinct 

 undulating brown line, parallel to and near the margin ; beyond upper 

 branch of median the space between this line and margin is brown, color 

 of apex of primaries ; fringes of primaries black at tips of nervules, yellow- 

 white in the interspaces, of secondaries nearly all fuscous, there being but 

 a few gray hairs in each interspace. 



Under side smoky-brown ; the white spots repeated, enlarged three 

 fold, each forming the pupil of a rounded, black ocellus ; secondaries have 

 a broad extradiscal band, ferruginous and lilac, with scattered yellow scales
