76 THE CANADIAN ENTOMOLOGIST. 



September i8th. — A few beetles seen, all in fall dress. One larva 

 found. This larva was brought home, but died before pupating. 



October 9th. — Searched again for P/iysonota, but could fine none. 

 Food plant almost entirely dried up and withered, so that the beetles had 

 probably gone into winter quarters. 



From these observations we may sum up the history of Physonota as 

 it occurs in this locality somewhat as follows : — With the return of sum- 

 mer the beetles leave their winter quarters, in which dress I have not yet 

 been able to ascertain, but by the latter end of May all are in the nuptial 

 dress. They then pair, and through June and July deposit eggs, the bulk 

 of these being laid during the former month. The larvae when young are 

 social, but when nearly full grown separate, pupating on the leaves. The 

 beetles from these issue from the beginning of August to near the end of 

 September ; the larger number appearing in August. These are all in 

 the fall dress of black and white, and hybernate before pairing. 



The places in which I find the species being rough ground overgrown 

 with plants and shrubs, I have, so far, failed to find them in their winter 

 quarters. 



As three of the beetles changed from the black and white of fall to 

 the nuptial dress while in confinement, we might expect to find them do 

 so under natural conditions, but two seasons' observations seem to prove 

 the contrary. Possibly in a more southern locality the species may be 

 double-brooded.
