250 THE CANADIAN ENTOMOLOGIST 



Mr. Smith stated that as much difference as is noticed between the 

 fauna of Washington and New Brunswick was also noticed in New Jersey 

 itself between the red shale and the sandy plains regions, while many 

 peculiar forms were found in the hilly north. 



Mr. Riley thought that by an exchange of specimens between Wash- 

 ington and New Brunswick it could be easily proved that the single or 

 double broodedness of the species was an acquired habit. He was 

 strongly of the opinion that those received at Washington from New 

 Brunswick would remain single brooded irrespective of climate, while 

 those received at New Brunswick from Washington would be double 

 brooded there. 



Mr. Lintner asked if this matter of heredity was not the same in the 

 difference noted between the thirteen and seventeen year Cicada. 



Mr. Riley thought that this was the case, the seventeen year Cicada 

 being a northern, and the thirteen year Cicada being a southern species. 



In reply to a question, Mr. Smith stated that most of the larger 

 Bombycids (Satiirniidce) were double brooded in New Jersey. 



The Club then adjourned until the afternoon, immediately after the 

 adjournment of Section F. 



The afternoon session was called to order by President Schwarz at 

 4.15, eleven members present. 



Mr. Hubbard read the following paper : — 



THE INHABITANTS OF A FUNGUS. 



BY HENRY G. HUBBARD. 



In the forest-clad portions of the Pacific Coast Range, from the 

 Columbia River northwards into British Columbia, there are frequently 

 seen on the trunks of pine trees which have been injured and blackened 

 by fire, small white fungi almost globular, or slightly flattened and kidney- 

 shaped, varying much in size, but frequently attaining the dimensions of 

 a pigeon's egg. This fungus, kindly determined for Mr. E. A. Schwarz 

 and myself by Prof. Galloway, is Cryptoporus (Polyporus) volvatus, 

 Peck., van obvolutus, Peck. It is very tough and leathery, and is remark- 

 able for the extension of the pileus, which forms a thick coriaceous veil, 

 covering the hymeneal surface below, and entirely enclosing it in a cavity 

 which retains the spores as they fall. A small aperture in the veil, less 

 than one-fourth of an inch in diameter, penetrates the cavity from beneath. 

 This opening is never in the centre of the underside, but is placed near
