PREFACE. 



After gathering together a fair collection of the British 

 butterflies and larger moths, I found, in company with 

 many other collectors of the British Lepidoptera, that, to 

 a certain extent, Eome was conquered, and fresh fields for 

 study must be opened up. Often it is not until this point 

 is reached that the attention is turned to the " Micros," 

 those marvellous little gems, of which many are so small 

 that the keenest eye can hardly see to appreciate their 

 beauty. Yet, with the perversity of human nature, it is 

 not till the eye grows dim, that the average Lepidopterist 

 begins his study of these fascinating objects. Possibly 

 there is a reason for this otherwise unfortunate delay. The 

 hand steadies, and becomes expert with practice, and the 

 setting of a Micro, which would daunt a beginner, becomes 

 easy to the experienced; hence the readiness in later life 

 to attempt the more difficult. Thus after years spent in 

 the preparation of the genitalia of the larger species, I 

 decided to complete my collection of slides of the British 

 Lepidoptera, and I now present the third volume of the 

 series, which deals with the Tortricidce. I have in this 

 volume been fortunate in securing the co-operation of the 

 Eev. J. W. Metcalfe, who, in his great love of the Science, 

 and at no little sacrifice, has made the drawings as fast 

 as I could obtain the specimens, and prepare the slides, 

 and I take this opportunity of offering to him my grateful 

 thanks for this most valuable help. The result has been 

 to speed up the work, and had it not been for the terrible 

 war. this volume, dealing with the Tortricidce, might have 

 been published in 1917. As this was impossible, I can now
