THE CANA.DIAN ENTOMOLOGIST. 185 



America. I used to take a few specimens in August in the Catskill Mts., 

 but the species was rare there. I have had many eggs sent me from 

 Truckee, Cal., and from Rochester, N. Y., the latter by Mr. H, Roy 

 Gilbert. The larvae sent me by Mr. Gilbert in former years refused our 

 native broad-leaved nettle, and starved to death on it, so that I was obliged 

 to import several roots of the food plant, U. dioica, from Rochester, and 

 grow it in my garden. I desired to see whether or no this species in larva 

 behaved like other of our Vanessans. Although so common, very little 

 has been published of Milberti at any stage, or of its larval habits. Say, 

 under the name Furcillata, figures the butterfly, 1825, and says it was 

 several times observed in the North-west territory during the progress of 

 the Long Expedition, but says nothing of the larva. Boisduval & Le- 

 Conte, 1833, also figure the imago, and say of the larvse merely that they 

 live in cluster on a species of Urtica in the neighborhood of Philadelphia. 

 Kirby, 1837, repeats Say, adding Canada as a locality. Harris, 1862, 

 briefly describes the caterpillar and chrysalis ; says the butterflies are rare 

 about Boston, but common in north-west Mass. and N. Hampshire, and 

 appear in May and again in July and August. Prof Lintner, Proc. E. 

 Soc. Phil, 3, 61, 1864, describes the mature larva, in part at least from an 

 alcoholic specimen, and the chrysalis ; and says there are two annual 

 broods of the butterfly (at Schoharie, N. Y.), in April and August ; that 

 the larvse are usually very abundant on Urtica dioica, but that nearly all 

 are destroyed by a parasite. Mr. Wm. Saunders, C. Ent., i, p. 76, 1869, 

 describes the adult larva, and says that the first brood of the butterfly 

 appears (London, Can.) toward end of June, and again in August, but 

 says nothing of larval habits. Mr. Scudder, in Syst. Rev., 1872, says of 

 Milberti, that the eggs are laid in clusters on some of the terminal leaves 

 of the nettle, that the caterpillars feed in close company during the earlier 

 stages, but subsequently scatter. Mr. Henry Edwards, Prbc. Cal. Ac. N. 

 Sci., 1873, briefly describes the mature larva and chrysalis. Mr. T. L. 

 Mead, in Report on Wheeler Expedition, 1875, ^^7^ that Milberti larvae 

 were common about Denver early in June on nettles, and that almost 

 every plant had many on it, in various stages of growth, while the females 

 were still depositing their egg clusters. Mr. Scudder, in " Butterflies," 

 1 88 1, p. 138, figures the butterfly, says there are two broods (in N. E.) in 

 June and September ; and on p. 99, gives figure of cluster of eggs on 

 under side of netde leaf ; says the eggs are laid upon the under surface in 

 large open patches, in which they are rarely if ever piled upon one
