the experimental farm system by the very efficient Dominion 

 entomologist, Dr. James Fletcher. 



OCTOBER 4, 1900. 



The r54th regular meeting was held at the residence of C. L. 

 Marlatt, 1440 Massachusetts avenue. President Gill occupied 

 the chair and Messrs. Busck, Dyar, Ashmead, Waite, Marlatt, 

 Stiles, Caudell, Kotinsky, Chapin, Currie, Howard, and Benton, 

 also present. 



Under the head of Short Notes and Exhibition of Specimens, Mr. 

 Chapin showed an abnormal specimen of Pyrameishunteri which 

 he had caught flying and which possessed a short abdomen and

 velop yellow color, which had resulted, by means of selective 

 breeding, in increasing the number of yellow abdominal bands 

 from 3 to 5. 



Mr. Kotinsky stated that he had found specimens of Aspidio-

Mr. Howard presented a list of nineteen species of Diptera, 

 collected in Hawaii by Mr. H. W. Henshaw, and named by Mr. 

 Coquillett. He stated that the distribution of these species was 

 extremely interesting, both as bearing upon the fact that the order
