PSYCHE.

shades barely indicating any markings 

 at all. It is hardly surprising that it 

 has been described under several names. 

 I have before me 2S $ and 34 o , 

 mostly taken by myself in Colorado and 

 the adjoining territories on the west 

 and north and at an elevation ranging 

 from 6000-8500', in July and August. 

 This is apparently the principal region 

 of its abundance, but it extends south- 

 ward to southern Utah (E. Palmer), 

 northeastern New Mexico (C. Thomas) 

 and the borders of Arizona (Thomas), 

 Arizona (Brunei - in litt. ), westward to 

 various localities in Nevada (H. Ed- 

 wards), Camp Hallock, Nev. (E. 

 Palmer), Ruby Valley, Nev. (R. Ridg- 

 way), near Lake Tahoe, California (S. 

 Henshaw in Capt. Wheeler's explora- 

 tions of 1S76), and the Sierra Nevada, 

 Calif. (H. Edwards) ; and northward 

 to Montana where according to C. 

 Thomas it was collected by Dr. E. 

 Coues, and west of which I have seen 

 specimens sent me by Mr. Brunei - from 

 Soda Springs and Coeur dAlene, 

 Idaho, and Yakima River, Washing- 

 ton, July iS; Brunei - also informs me 

 that he has specimens in his collection 

 from Ft. McKinney, Wyo. ; Salmon 

 Co., Henry Lake, Beaver Canon, and 

 Camas Prairie, Idaho ; Colville, Wash- 

 ington ; and even from Ft. McLeod, 

 British America. It is twice stated by 

 C. Thomas to occur in southern Illi- 

 nois, but by a wrong identification for 

 H. (//•) haldemanii ; it does not seem 

 to occur east of the foot hills of Colorado, 

 the easternmost localities known to me 

 being Blackhawk, July 2 (A. S. 

 Packard), Beaver Brook Canon, 6000', 

 July 11, and Georgetown, 75-S500', 

 July 12-18 (S. H. Scudder), and Man- 

 itou, 6300' (July 14, A. S. Packard, 

 and Aug. 24-25, S. H. Scudder). 



HlPPISCUS (X.) MONTANUS. 



Oedipoda montana Thorn!, Rep. U. S. 

 geol. surv. terr., 5,462-463; Syn. Acrid. N.

 pi. 12, fig. 12. 



Hippiscus montanus Sauss., Add. prodr. 

 Oedip., 170. 



This species appears to be wide 

 spread though rather rare, perhaps 

 local. It comes from Idaho (Franklin, 

 June 12, Bruner), and Thomas also 

 reports it from the upper part of the 

 Snake River plain near the mountains, 

 and in southern Montana. He adds 

 that it was not noted south of Market 

 Lake, but from the north or Atlantic 

 slope of the range to Virginia City in 

 Montana. Two of his types which I 

 have seen through the favor of Dr. 

 Riley are marked as coming from Mon- 

 tana and Idaho. But it also occurs 

 further south and east, for it is found in 

 the southwestern part of Holt Co., 

 Nebr. (Bruner), and the greater part 

 of the Sand Hill region of central and 

 western Nebraska (Brunei - in litt.), as 

 well as in New Mexico (Taos Valley, 

 Brunei - in litt.) and at Holbrook, Ari- 

 zona (Brunei - ) . 



Hippiscus (X.) lateritius. 



Xci7ithippus lateritius Sauss., Prodr. 

 Oedip., 92-93. 



I have not seen this species, which 

 seems from Saussure's description to 

 fall in this immediate neighborhood. 

 It is described from Nevada. 



Hippiscus (X.) calthulus.
