 Ceranibycidse with notes," Trans, xii, 1885. 



In tlic stndy of this sul)fainily tlie specimens that accnmnlate dis- 

 j)hiy ditferences in color, in punctnation and in vestiture, tliat do not 

 always indicate specific difference. Tlie influence of climate and of 

 the food-})lant is very marked, and the variation thereby occasioned 

 has led to the description of some species that are now considered 

 races or synonyms. Where slight difference in color, etc., accompany 

 difference in food-plant or locality I have considered them indicative 

 of races ; where these differences, though they may seem of consider- 

 able import when only two extremes are compared, are connected by 

 intergrades I have considered them as indicative of individual 

 variation. Should the reader possess only the two extremes, I beg 

 him to believe that the intergrades, nevertheless, do exist. 



It is a pleasure to acknowledge the assistance I have received from 

 Mr. Frederick Blanchard and Dr. John Hamilton, to whom I owe 

 many of my specimens; to Mr. Samuel Tlenshaw, who has revised 

 the lists of localities given ; and to Dr. Horn, who has allowed me 

 to use his collection and library, and, in addition, has given much 

 advice throughout the paper.
