enter into the question of scientific nomenclature. He thought 

 that any one discovering a preoccupied name not only had a 

 right to propose a new one, but it was his duty to do so, without 

 waiting to see if he was trespassing on any one's preserves. He 

 deprecated the practice of waiting for some one else to correct a 

 homonym, for the chances were that this might not be done for a 

 long time, and the error thus lost sight of and perpetuated. 

 Provided the proposer of new names had enough knowledge of 

 the group not to make matters worse by proposing a new name 

 when there was an old synonym that could be resurrected, he 

 thought such persons were conferring a favor on science and should 

 not be discouraged by disparaging comment. In reply to Mr. 

 Ashmead's remarks he pointed out that the changes in names in 

 Dalla Torre's Catalogue were unavoidable and perfectly proper, 

 after the several genera had been united, and that such a union 

 of genera was well within the right of the cataloguer. 



Dr. Gill said that his views coincided with those of Dr. Dyar, 

 and Mr. Pollard stated that in proposing new names in botany 

 the personal element was eliminated. 



Mr. Busck has submitted the following paper for publication : 



DIMORPHISM IN THE CODLING MOTH. 



(Cydia simpsonii, n. var.) 



By AUGUST BUSCK. 



In his bulletin on the Codling moth,* Mr. C. B. Simpson men 

 tions a moth " Found on the trunk of an apple tree that had all 

 the appearance of a codling moth, except the color, which was 

 buff and gold throughout, the bronze spot being much the same 

 as in the codling moth. During the summer of 1901,4 well- 

 preserved and 8 badly worn specimens, having the same color, 

 were bred among the common codling moth from apple, and 2 

 others were observed in the field. Mr. Hitt, of Weiser, Idaho, 

 found 7 of these moths among 50 moths bred in 1896. Whether 

 this is a variety of Carpocapsa pomonella or another species, 

 has not yet been determined." [Simpson.] 



During last summer, Mr. Simpson bred 6 more of these light-
