Whilst to others who have rendered me noble 

 assistance, my thanks come too late. For years that 

 queen of entomologists Mrs. Emma Sarah Hutchinson, 

 put aside for me spoiled specimens of rarities she was 

 breeding, thus helping to spare my feelings in having to 

 sacrifice cabinet specimens. The late John E. Robson 

 that kindest of entomologists, who placed his entire 

 cabinet at my disposal. The late Charles G. Barrett, 

 J. A. Clark, Dr. Philip Mason, the Rev. Joseph Green, 

 and my companions in field work George A. Harker and 

 Rathbone Hughes. Alas ! They are no more. 



I also particularly wish to acknowledge my debt of 

 gratitude to my friend the Rev. C. R. N. Burrows, whose 

 love of accuracy has so greatly helped me in the 

 production of the letter press. His unwearying care in 

 correcting the proof sheets, and his many suggestions 

 for elucidating difficult passages, have proved him to be 

 a valuable friend, especially to one who for so many 

 years worked entirely alone.
