ofjiciualc .1 , with which he was not acquainted. I did 

 not then know the plant, Imt after several unavailing trips in 

 search of it stumbled upon it, growing- in scattered groups over 

 an area a few acres in extent on the bank of the Connecticut 

 River, near Claremont. The locality was too remote and diffi- 

 cult of access to permit of its being used as a base of supply ; 

 so I dug up a number of plants and set them in a box of earth 

 at home. Some of the plants examined on this and subsequent 

 trips to the same spot had small larvae upon them, which after- 

 wards proved to be llaploa. Mr. Bradley fed his larvae chiefly 

 upon mint, but neither his nor mine survived the winter. 



Late in the autumn of 1898 I found a second colony of (>;/<>- 

 glossnm in a rocky pasture on the crest of a hill several miles 

 from the first and under quite different conditions of soil and 

 altitude. 



The root leaves of the one-year plants ( the plant is a bien- 

 nial, producing only root leaves the first season) had survived 

 the hard frosts, and many had oval holes in them like those 

 made by IIaf>loa larva?, but no larvse could be found, though 

 search was made in the dead grass and rubbish about the roots 

 of the plants where the larvae might be thought to hibernate. 



I resolved to visit the spot the following spring, and did >< > 

 in May ( 1899), when I was rewarded by finding numbers of 

 partly grown larvse. These I brought home, and I then had 

 some L'vno^losum growing in my garden from seed, I had no 

 difficulty in rearing them. 



I thus obtained eighteen imagos, one of which, to my sur- 

 prise, was a clymciic. The others, though showing quite a 

 a range of variation, were referable to roufnsa, except one 

 dwarfed specimen marked like Iccoiitci var. niilitaris. I had 

 not observed any differences among the larva-. These imago^. 

 except the $ civilian , were placed on growing Cynoglossum 

 plants, under a netting, and a few days later an abundance of 

 eggs was found. One lot of about forty laid in a close group, 

 evidently by a single female, was removed and the larvae reared 

 indoors. The other eggs, laid mostly on the under surface of 

 the leaves, were left to hatch where they were laid, and the 

 tub in which the plants were growing was kept covered with 

 fine netting. Scores of larva- hatched, but soon all had disap-
