congratulans, as Gundlach bred, not only the dark as well as 

 the normal form of rimosa, but also the intermediate, all from 

 the same batch of larvae, and my more recent series, with its 

 several intermediates, seems to confirm the fact. 



Besides the above there is a third, and still tindescribed 

 form of rimosa from Cuba. This differs so much in color as 

 well as in pattern from rimosa rimosa, that I am almost tempt- 

 ed to give it specific rank. This may be decided later; for the 

 present it may be known as : 



Isognathus rimosa woodi n. subsp. 



Differs in general appearance from rimosa rimosa in having the 

 ground colour of the forewings blackish instead of greyish. 



Male: Expanse (one wing) 42 mm. Female: Expanse (one wing) 

 46 mm. 



$ . Upperside. Forewings blackish-brown divided perpendicularly 

 into two parts by a greyish-white band which begins as a broad costal 

 patch, just beyond the cell, narrowing at the center of the wing, and 

 again broadening into another patch at the inferior margin. 



Hindwings with marginal band entirely blackish-brown, nearly 

 black, otherwise as in rimosa rimosa. 



Underside. Forewings and hindwings with a broad marginal black- 

 ish brown band, perceptively darker toward its interior edge. Re- 

 mainder of wings similar to rimosa rimosa. 



9. Similar to $, but dark portions of wings are intense and uni- 

 form in color. 



Body same as rimosa rimosa. 



Types $ and 9 deposited in the collection of the Academy 

 of Natural Sciences of Philadelphia. Paratypes in the collec- 

 tion of the author. Specimens taken, $, July 12, 1911; 9, 

 May 3, 1914, at electric light, Guantanamo, Cuba. 



These specimens have long lain in my cabinet, and it is at 

 the instance of that enthusiastic, and far too modest student 

 of the Sphingiclae, my very good friend, Mr. William C. Wood, 

 of New York City, that I have decided to describe this insect, 

 which I take pleasure in naming for him.
