THIRTY-THREE NEW SPHINGIDAE 



BY BENJAMIN PRESTON CLARK 



In describing these new forms of Sphingidae, bringing the 

 total now described by me to one hundred, I wish again to 

 acknowledge the help given me by scientists all over the world, 

 who have made this possible. 



My collection has now reached a total of twelve hundred and 

 twenty-two species and subspecies, represented by some eighty- 

 four hundred specimens. The total number of species and 

 subspecies now known is, according to my records, thirteen hun- 

 dred and fifty-four. I lack therefore one hundred and thirty- 

 two of the known forms, most of which are represented by one 

 or two or three specimens, chiefly in public museums. While 

 their rarity makes it increasingly difficult for me to acquire 

 additional forms, the method of sending a photograph of the 

 type specimen to a collector living near the locality where it was 

 taken, has proved an effective one, and the very difficulties 

 stimulate increased effort, for the scientific value of a complete 

 collection of a family so widely dispersed throughout the world, 

 as are the Sphingidae strongly appeals to men of science. 



Rare and even type specimens have been given me, because 

 it is known that my collection is not, in the ordinary sense of 

 the term, a private collection. It is held by me simply in trust.
