 and are found at Center, but not, I believe, elsewhere in New York.

NOTES ON THE FOOD PLANT OF HEMILEUCA MAIA. 



Last season I reared a brood of this rare species from eggs sent me by 

 my worthy friend, Wm. Provis, of Detroit. The locality where he found 

 the eggs is in Oakland County, Mich., known as the 5,000 acre tract, and 

 so low and marshy that it is covered with water part of the year. In his 

 interesting letter, giving a description of the place, he says : " The timber 

 is mostly swamp oak and willow, and the land so low and wet I found 

 great difficulty in getting about." Mr. P. was too late to find any of the 

 larvae, they having finished their growth and entered the ground, but the 

 imagines were very plentiful, flying about in a very lazy manner, and 

 occasionally dropping down in such a way as to induce one to think they 

 had been injured.. 



Many of the females were depositing their eggs — not, as my friend 

 had expected, on the oak — but on a species of wild aster found in 

 abundance in the locality. The oak and aster are, botanically speaking, 

 widely separated, and yet the female, whose instinct ought to teach her 

 what course to pursue for the welfare of her oftspring, is found depositing 

 her eggs on the latter as well as the former, which goes to show that the 

 food plants of this species have a far wider range than had been previously 

 supposed. To convince me he was correct, Mr. Provis sent me a stem 

 of the aster with a cluster of eggs in the form of a ring glued to it.
