before I found that there was no material for illustrating the imagines 

 of A. medon and L. avion, for which the numbers xx. and xxix. had 

 been left respectively. The volume is, however, illustrated by forty- 

 one plates, which, without attempting to vie with the number in the 

 previous volume, is largely in excess of those appearing in preceding 

 ones. 



It had been hoped also to deal with Hamearis lucina in this volume, 

 but the notes left by Mr. Tutt on this species were insufficient to give 

 his views on this group, and had they been otherwise the volume 

 would have been swollen beyond due proportions. It was therefore 

 necessary to be content to leave off at the end of the Lycaenidae. 



In conclusion I cannot refrain from recurring to the fact that the 

 difficulty of finishing a work by J. W. Tutt is necessarily enormous, 

 and can hardly do better than quote Aaron Hill, the author of the 

 libretto of Handel's opera Rinaldo, in his appeal to the "Indulgent 

 Reader," when he says "Let this Work therefore satisfy you, and, if not 

 deserving of your Praise, do not withhold at least your Compassion."

NOTE. 



The late Mr. J. W. Tutt's Executors (Messrs. Herbert E. Page, 

 George Robinson and Henry Smetham), charged under the terms of 

 his Will to complete this volume, deeply welcome its conclusion. They 

 cannot appreciate too highly the able and affectionate labours of the 

 Reverend George Wheeler and his band of willing helpers. Of the 

 scope of the work and the complications of its material some conception 

 may be gathered from Mr. Wheeler's own words. The extent of those 

 labours can only be known to Mr. Wheeler himself. The scientific 

 knowledge requisite for such a task carries its own evidence in its 

 pages. The Executors cannot let the publication pass without 

 expressing their warmest acknowledgments of a labour so affectionate 

 and so capably and satisfactorily completed.
