write up their life-history later. They fed heartily and were 

 beauties from the first. Their appearance was so neat and trim 

 and the coloration and shape such that even a hater of ' worms" 

 could but admire these. When ready to start home neither had 

 pupated, but the trip was made in a jelly glass and both retained 

 their appetites on reaching Illinois. The first pupated August 

 28th, and the second September 8th. The first chrysalis is i^$ 

 in. long, in every way resembling P. asterias, color gray, with 

 dark band along each side. I regret that I cannot give the time 

 from egg to pupa, but both were found in the larvae state, the 

 first on July 25th. Female daunus confined with poplar and 

 chokecherry leaves failed to oviposit even after repeated trials. 

 Along the trail previously mentioned Anthocharis ausonides and 

 Stella were quite frequently seen, but were always wary. 



On an open table-land covered with dwarf poplars and a wild 

 gooseberry; Grapta zephynis and Nemeophilapetrosa, were found, 

 but only three of the former and one of the latter. Clisiocampa 

 californica was an abundant species and very destructive to the 

 native vegetation. On June 29th, I picked at least a pint of the 

 cocoons from the chokecherry bushes in about ten minutes. On 

 the tops of the mountains were found P. smintheus and C. 

 chryxus in abundance, a few Papilio zolicaon, Pieris occidentalis, 

 Melitcea nubigera, Nisoniades lucillus, and a Papilio resembling 

 ajax in general appearance, but larger. 



The plants on and near the tops of the mountains were of two 

 species, Leduin debile and wrightii. These moss-like plants, 

 growing on the rocky hill-sides, where nothing else could obtain 

 a foothold in the barren soil, were often eaten close to the ground 

 by the larvae of Parnassius smintheus. Frequent and continued 

 search and digging revealed a very few larvae and three empty 

 pupae cases. This led me to think that I searched in the wrong 

 season. A female smintheus confined with a transplanted plant 

 of Ledum oviposited two eggs which proved to be not fertile. 



On June 3Oth, a trip was made six miles to the south and three 

 notes concerning it seem worthy of mention. Near the bare top 

 of a high mountain, probably 9000 feet elevation, a perfect swarm 

 of Melicleptria villosa was discovered. On the level rocky top 

 C. chryxus was abundant, and could be easily taken by working 

 against the wind. About noon while sitting down to put some 

 of my captures in papers, hundreds of Cocdnella passed me
