THE CANADIAN ENTOMOLOGIST. 



" This butterfly {Ismeria) is found over a wide extent of territory, being 

 known south of lat. 40" from the Atlantic to the Rocky Mountains, and 

 at the higher levels of the west, even into the heart of Colorado, and as 

 far north as Montana, and, according to Geddes, at Brandon, Manitoba. 

 Little is known of its history, or how many broods there are, or hov/ it 

 passes the winter .... It awaits a biographer." French, Butt., p. 175, 

 gives as its habitat, " Southern and Western States, Rocky Mountains, 

 Montana to Arizona, occasionly in West Virginia." Mr. T. L. Mead, 

 Wheeler Report, 1875, p. 763, says : " Not uncommon at the lower levels 

 and at Denver. Females much worn were taken early in June, so it is 

 probable that the species appears about the first of May, though some- 

 what later in the mountains." 



Mr. Bruce writes : — " Carlota is common in every part of Colorado 

 that I have visited, and in the eastern part of the State is par- 

 ticularly abundant up to about 8,000 feet altitude. At and near 

 Denver it flies early in May and again in midsummer. There are also a 

 few individuals in September, a partial brood. In July, it may be seen 

 near the foothills and in neglected clearings on flowers, the many species 

 of Erigeron being the favourites. The disks of these flowers v/ill be hid- 

 den by the many Carlota and with them P. Camillus. It collects in im- 

 mense swarms in certain damp places, such as where a stream has over- 

 flowed and left the ground in that condition. Larvse of all sizes can be 

 found almost all summer in great numbers upon the leaves of the food- 

 plants. I have sometimes seen hundreds of them running along the 

 railway track in search of food, having eaten every leaf from the patch of 

 sunflowers where the eggs had been deposited, at the edge of the prairies 

 and along the various canons and gulches." But Mr. H. W. Nash, at 

 Pueblo, writes me he has rarely seen this species there. 



I have never seen this butterfly on the wing but once, and that was at 

 Coalburgh, May 3, 1878, when a fresh male was taken near my house. 

 On 17th July, 1867, another was taken here by a visitor. Mr. A. D. 

 Hopkins, of the West Virginia Agricultural Station, at Morgantown, 

 writes me that on July 8th, 1890, he found Carlota abundant in Upshur 

 Co., on the summit of Stone Coal Mountain, flying in the road and in 

 damp places on the road. 



The single mention in books of any of the early stages is by Mr, Dyar, 

 Can. Ent., XXV., p. 93, 1893, who briefly describes an adult larva found
