Mr. Walker's type is simply a rather small specimen ; it does not differ more from 

 the examples referred by Mr. Walker to Sphinx brontes than they do from each other, 

 the primaries being 5 millims. less in expanse than Boisduval's figure, and the pattern 

 almost identical.

"Tropical Insular District!" 



Sphinx pamphilius of Cramer, placed by Messrs. Grote and Robinson as a second 

 species of this genus (P. E. S. P. v. p. 1 89), is certainly a Diludia. 



1 Seems allied to Daremma ; in the description a comparison is drawn between it and Dilwlia. Mr. Grote 

 has proposed (1866) to withdraw it as a genus ; but I rather doubt the adTantage of this step.
