42 TFIE JOURNAL OF THE 



On June 6, 1879, I found some fawn-colored larvse on 

 the hazel-bush with dark-colored tufts, but did not succeed 

 in raising them. 



In the summer of 1880 I experimented still fiirther with 

 results similar to those above cited, with the exception that 

 the proportion of males was greater. 



While I have not been able in this article to prove any 

 connection between the changes in color and sex in these 

 larvae, the experiments have been full of interest to me, at 

 least, and I have shown that they are general feeders, eating 

 almost all kinds of vegetation, cabbage included. I think 

 1 have also shown that Orgyia leucostigma and O. antlqua 

 of Harris are forms of the same species. Possibly, however, 

 that requires some further experiment. 



THE DISTRIBUTION OF THE IVORY-BILLED WOOD- 

 PECKER {CAMPEPHILU8 PRINCIPALIS) 



By C. J. Maynard. 



As this 'Trince of Woodpeckers" is becoming very rare, 

 being now restricted, as far as I can learn, to a very limited 

 area, a few notes on its former distribution, as compared to 

 its present range, may prove acceptable. 



William Bartram in 1792 says that it is resident in Florida 

 and the Carolinas. Wilson, writing in 1811, states that it 

 occurs from New Jersey to Mexico, but adds that it is rare 

 north of Virginia. Nuttall, evidently with this information 

 in mind, says that it occurs in the Southern States, but is 

 seldom found north of Virginia. He also states that it is 

 found in Mexico and Brazil, but in these latter instances he 

 evidently had another species, the Imperial Woodpecker 

 {Cmnpephihf.^ wiperiali^) in mind.
