 streak near the internal angle of the same color. Fringe of the exterior margin

This description is after Mr. Hy. Edwards, and is t'0{)ied because 

 I could not im|)rove on it. I regret that I can find nothing of its 

 early stages which might add something to our knowledge of the 

 location of this peculiar form. It is extremely rare. 



POSTSOKIPT. 



The manuscript of the foregoing monograph was jn-actically com- 

 pleted nearly two years ago. A variety of i-easons prevented its 

 immediate presentation foi- publication, and after acceptance it was 

 compelled to take its turn. For over six months it has been run- 

 ning through the press, and before it finally reaches its i-eaders the 

 work will be fully two years old. 



In an order like the Lepidoptera, and an attractive family like the 

 SphingUhe, two years often suffices to greatly increase or improve 

 our knowledge, and a monograph long delayed may become anti- 

 quated even before being published. In the present case no such 

 ffitality has taken place; but there have been several publications 

 referring to the family, since its completion, and I have been able in 

 some cases to see a nuich greater material than was accessible to me 

 at the time of writing. Mr. Edwards has publislied also one new 

 species since the MSS. went to the ])rinter. The bibliographical ref- 

 erences are therefore not quite up to date in all cases, but are, I think, 

 complete to the beginning of 1888. 



The greater material seen has, until quite recently, but confirmed 

 my conclusions. In August, 1888, I had an opportunity of studying 

 the collections of Mr. David Bruce, of Brockport, N. Y., containing 

 many rare species, and large series of others taken by Mr. Bruce in 

 Colorado. On two points this collection modified and corrected con- 

 clusions arrived at from lack of larger material. I find that I had,
