THE CANADIAN ENTOMOLOGIST. 149 



are four or five varietal forms illustrated by Blatchley (after Riley), 

 liut these do not include the forms I have just mentioned. Along 

 the railway track, not far from this swamp, I took both species of 

 Crioceris on plants of wild asparagus. 



The genus Chrysomela has always been of great interest to 

 me. I suppose because of its beauty, and, seeing in one of the 

 books that the sub-species rhoda fed exclusively on hazel, I made 

 a systematic search for the insect, but without any success. The 

 only capture I have made on this plant is a species of Balaninus 

 or nut-weevil, one of the wariest of insects; I have distinctly seen 

 (and more than once) Balaninus swoon from the leaf it was resting 

 on, while I was still several feet away; it invariably feeds in such 

 a position as to drop into the tangled heart of the bush instead 

 of falling exposed at the side. But the frequent occurrence of 

 Chrysomela: scalaris and philadelphica in varietal form on alder, 

 coupled with their entire absence from hazel, rouses a suspicion. 

 In size and habit, as well as character of foliage, the alder and the 

 hazel are very similar, especially to a non-botanist: it would be 

 interesting to get a consensus of opinion (or, rather, experience) 

 in the matter from other field-collectors. 



Another beetle, said by Blatchley to be beaten from hazel, 

 is Syneta ferruginea. I had seldom seen this beetle (and never 

 more than one at a time) till last season, but in testing out the 

 alder as a food plant of Chrysomelas I took three or four pairs of 

 Syneta ferruginea on leaves of alder near Bethany. The robust 

 red-brown form of Chr. philadelphica I have now taken, two 

 seasons running, and on alder, as far west of Peterborough as 

 Mount Pleasant, and also two or three miles east of the city on 

 the outskirts of my second hunting ground — Burnham's wood.
