The Ottawa Naturalist. 



[October 



tussock moth which has caused much havoc to vegetation, and 

 spoke of four different kinds of caterpillars which he had collected. 

 These were the hedge -hog caterpillar, the checkered tussock 

 moth (Halisidota) , the hickory tussock moth (Halisidota Caryae) 

 and the salt-marsh caterpillar. All of these are common species 

 belonging to the family Arctiidae, and with the exception of the 

 first named, which live as a caterpillar all through the winter 

 under boards, etc., spin their cocoons during the autumn, the 

 moths emerging the following spring. The curious caterpillars 

 of the large skipper butterfly Edanius Tityrus were found in 

 their snug tents among the leaflets of the black locust and 

 elicited much interest from their curious markings. They have 

 black heads with two large orange eye-like markings, crimson 

 throats and large yellow bug-like bodies dotted and streaked 

 with black. Several handsome spiders were also found. Mr. 

 Clark the secretary added his quota of interest and information. 



Plants of interest found were : 



Linaria vulgaris, the interesting Peloria or monstrous form 

 which bears flowers of an entirely different form from those of 

 the typical plant. These do not perfect seed. 



Maples. Sugar Maple, Striped Maple, Spiked Maple, Red 

 Maple, Silver Maple. 



Ash. Red, White and Black Ash. 



Birch. Cherry Birch, Yellow Birch and two forms of the 

 Canoe Paper Birch. 



Beech. Blue Beech, and the True Beech. 



Iron Wood. 



^urple Vervain and Lop-seed. 

 With a regretful turning away from the woods and lake side 

 covered with burs and glory through paths carpeted with falling 

 leaves "The Swan song of the leaves" gold, crimson and brown, 

 the Club returned from a most enjoyable, if the last of the 

 summer's excursions.
