banded the trees with cloth or straw, and that these bands serve to col- 

 lect the codling-moth larva?, which were then destroyed. 



Mr. Gillette had observed the larvae of this insect mig-rating on the 

 tree trunks in the spring, contrary to what was supposed to be their 

 usual habit. He had observed the larvae leaving their winter cocoons 

 and moving about on the tree trunks at this time. Tn his opinion 

 banding the trees in the spring was a valuable means for lighting the 

 insect. 



Mr. Johnson, in explanation of the common name of Nectarophora 

 desPnwtor, stated that this name had been decided upon jointly by 

 Messrs. Pergande, Chittenden, and himself; that while the name was 

 perhaps open to criticism, it was probably as appropriate as an3\ He 

 also called attention to Mr. Lounsbury's statement that the red scale 

 occurred on other than citrus trees in South Africa, which fact is of 

 great importance and worthy of emphasis. 



Mr. Lounsbury said that the red scale was a very common pest on 

 the pear in South Africa, that it had an extremely wide range of food 

 plants, and that its effect on growing wood was similar to that of the 

 San Jose scale. 



Mr. Felt, discussing the matter of common names of insects, 

 expressed the opinion that a strict enforcement of the law of priority 

 is hardly practical in such cases. It is difficult to change a well-estab- 

 lished common name, however inappropriate it may be. He cited the 

 failure of an attempt to change the common name of Cllsiocanqxi diss- 

 tria from "forest tent caterpillar" to "forest tentless caterpillar." 



Mr. Fletcher felt that entomologists were open to grave criticism 

 in not establishing appropriate common names for injurious insects. 

 He suggested the appointment of a committee to secure uniformity in 

 common names of insects. 



Mr. Woodworth, referring to an experience in this line in California, 

 stated that the board of horticulture of that State had formally voted 

 to call A.spidiotus j?c'/viic/r«y/s the "pernicious scale," but in spite of 

 their efforts to secure a standing for this name the pest was still gen- 

 erally known as the " San Jose scale." 



Mr. Hopkins discussed at length the confusion arising from varia- 

 tion in common names. It was, in his opinion, highly desirable to 

 have a uniform common name for each injurious species, similar to 

 those adopted by the American Ornithologists Union. He also moved 

 the appointment by the chair of a committee on couunon names. 



Mr. Johnson, referring to the motion just made by Mr. Hopkins, 

 called attention to the lack of system in selecting common names of 

 scale insects. For instance, Aspidlotu.'i ancyhix Putnam was known 

 as the " Putnam scale," Asiyldiotus forbesi Johnson was known as the 

 "Forbes scale," etc.
