THE CANADIAN ENTOMOLOGIST. 13 



the camera. In these studies I found characters by means of which I 

 could separate the species ; others which separate the genera ; and still 

 others which separate the subfamilies, or families, as some call them. As 

 the Club was not a part of the .American Association, the paper was not 

 published, nor has it ever been published, though many of our prominent 

 entomologists were present and heard my paper." 



" Mr. Meyrick, in his Descriptions of New Zealand Microlepidoptera, 

 Phil. Inst, of Canterbury for 1S84, p. 141, after giving a recasting of his 

 definition of the Torti-icidce and GrapholitJiidce, says : ' I am indebted 

 to Professor Fernald, well knov/n as a special authority on this group, for 

 the information on which this change is founded. He states that the 

 genital uncus never occur.« in the GrapJiolithidce, and considers that such 

 genera as Ctenopseustis, hereafter described, should be therefore referred 

 to the Tortricidcc ; which amounts to saying, that the possession of the 

 uncus is a more valuable systematic character than the possession of the 

 basal pectination (of the median fold of the hind wing). As Professor 

 Fernald has devoted much labour to the investigation of material from all 

 parts of the world, there is little doubt that he is correct, and I have 

 adopted his suggestion. I have not yet found leisure to examine the 

 genitalia of all the Tortricina of this region, but I have investigated a few 

 species, which appear to confirm his views ; and in the case of the 

 Pyralidina, I have found the same character valuable for family separa- 

 tion.' " " In the same paper, page 146, Mr. Meyrick establishes the genus 

 Ctenopseustis for Walker's Pcedisca ohliquani, and under it says : 

 ' Professor Fernald assures me that the genital uncus of the male (the 

 value of which as a divisional character he was the first to discover in this 

 group) is never developed in the Graphoiitkidce, and that this species 

 should be included in the Tortricidce, notwithstanding the pectination of 

 the lower median vein, this latter structure being indeed also found in 

 Oenectra, which is certainly referable to the Tortricidce. In this view I 

 quite concur, and therefore jjlace the species here, which involves the 

 formation of a new genus for its reception.'" 



" I write this to show why I could speak so confidently of the value 

 of your classification of the Phycids." 



It will thus be seen that my use of the genitalia in classification, while 

 independent of, because I was ignorant of, the work of Prof. Fernald and 

 Mr. Meyrick, was far from being original in time or in inception. Prof 

 Fernald was the pioneer in the work,, and to him belongs the greater guilt,
