196 THE CANADIAN ENTOMOLOGIST. 



species of Limenitis are identical until it could be proven positively by- 

 rearing the one supposed species from the eggs of the other. 



Mr. Scudder exhibited a piece of a woody root which was represented 

 as coming from the interglacial beds of clay near Toronto, Ontario. This 

 root proves by microscopic examination to belong to a species of Juniper 

 and is bored by an insect, probably a Scolytus, but one which differs 

 materially in its habits from any known species now existing. Mr. Scudder 

 also referred to the abundance of insect remains which he had found in 

 the peat deposits on the Island of Nantucket ; from one mass of about a 

 cubic foot he had obtained 300 fragments of Coleoptera, among which 

 were several which he had been unable to refer to any species now known 

 to exist ; a number of these specimens were shown to the members. 



•Mr. Austin exhibited specimens of a wasp, Polistes metrica Say, infested 

 with parasites. 



On motion the meeting was adjourned until 8 p. m. 



EVENING SESSION. 



Prof. Comstock exhibited specimens of a small Pyralid which is car- 

 nivorous, feeding in the larval state on the maple tree bark-lice, under the 

 cottony matter secreted by the lice. He had bred forty of the moths fed 

 in this way. 



Mr. Scudder drew attention to a very singular fossil, of which he had 

 obtained about 100 specimens, somewhat resembling the larva of an 

 insect, but yet quite different from anything hitherto known. His remarks 

 were illustrated by a figure of the object. It consists of only six segments. 



Mr. Barnard exhibited specimens of Phymata erosa, which has proved 

 quite destructive to other insects; they have been known to destroy quite 

 a number of Pieris rapes. Mr. Barnard exhibited a number of specimens 

 which had been caught on the burrs of the Burdock. 



Prof. Riley stated that Pieris rapce was now quite common in Ala- 

 bama ; it had been seen as far as.Selma, but had not yet reached Mobile. 

 Mr. Scudder remarked that it had been found in Savannah, Ga., two 

 years ago. 



Prof. Comstock had received specimens of the Colorado Potato Beetle 

 this year from Manitoba, and thought that this was the farthest point 

 north it has yet reached. 



Mr. Saunders made some remarks in reference to the capture of insects 

 by the flowers of a species of Bidens, probably chrysanthemoides ; the
