ENTOMOLOGICAL WORK IN COLORADO. 299 



elevations ranging from 6000 to 9000 feet above the sea. The 

 creeks mostly run in rocky caiions, which support an abmidance 

 of scrub-oak {Qiicrcus undulata, Torrey), together with charac- 

 teristic cacti and other low plants. Of larger trees, the principal 

 conifers are spruces at higher elevations, and pines {Pinus 

 ponderosa) throughout in suitable places, while deciduous trees 

 are represented chiefly by cotton woods {Pojndiis, two species). As 

 regards previous investigations, various species of insects had 

 been recorded from Pueblo ; . but for the district now to be 

 explored, no records whatever were forthcoming, except a few 

 notes received through the kindness of Mr. H. W. Nash, of 

 Pueblo, relating to butterflies taken by himself, viz., Papilio 

 daunus, Bdv., Lower Hardscrabble, Custer Co. ; Neophasia 

 mcnapia, Feld., Hardscrabble Canon, Custer Co. ; Pieris occi- 

 dentalis, Keak., Hardscrabble ; Argynnis cipris, Edw. (I have 

 taken this by Short Creek, Custer Co., about 8400 ft. alt., new to 

 Custer Co.), Beulah, Pueblo Co.; A. edwardsii, Eeak. ; and 

 A. halcyone, Edw., Hardscrabble Pass, Custer Co. ; Satyrus 

 alope, Fab., Beulah; Lemonias nais, Edw., Hardscrabble Canon; 

 Thecla crysalus, Edw., Hardscrabble Cailon ; Lyccena antiasis, 

 Bdv., Hardscrabble Canon ; and Nisoniades hrizo, B. & L,, Hard- 

 scrabble : 11 species in all, two from Pueblo Co., and the rest 

 from Custer. To these I had good hopes of adding. 



We started on July 31st, (1888), and passing through West 

 Cliff and Silver Cliff, stopped at noon near a mining town called 

 Bassickville, or more euphoniously, Querida. This is on the 

 western slope of the Wet Mountains, and therefore not in the 

 district we went to explore ; but I may note that the only 

 insects observed were Danais plexippus, L., and Colias eurytheme, 

 Bdv., with the pale var. of the female, jxdlida, Ckll. After lunch 

 we pushed on, and by evening reached the upper part of the 

 Hardscrabble district, camping near Comargo, or rather what 

 was Comargo, since the mining camp of that name has ceased to 

 be. This was the first locality in the new district, so I looked 

 around that evening, and was rewarded by a few interesting 

 plants, including an interesting variety {pallescens, v. nov. rather 

 smaller than type, raceme denser and shorter, flowers cream- 

 colour, leaves numerous) of Liqnnus argenteus, Pursh ; but the 

 insects were represented only by a larva of D. p)lcxippus, which 

 was about to pupate under the bark of a felled pine, and
