Jamaica (Argent) ; Haiti (Tweedie). g jyj 



I think it very probable that Drury's type came from Jamaica. It was described from 

 the collection of Dr. Fothergill ; and all the species noted as from that collection are 

 said to come either from Jamaica or New York ; so that a locality ticket may easily have 

 been transposed. Moreover our example from Jamaica agrees better with Drury's figure 

 than those from Haiti, although still differing in the indistinctness of the pale trans- 

 verse band of secondaries. In the event of the two species proving not to be identical, 

 the Insular type will, of course, have to take Walker's specific name and Grote's generic, 

 and will then stand as Diludia collaris. I cannot but regret that Mr. Grote has thought 

 it necessary to add to the synonymy by proposing names for species before they 

 were required. It is true that he might otherwise have been superseded ; but, as a fact, 

 it does not matter who names a species, so long as the name given be euphonious, whilst 

 on the other hand a cumbrous synonymy is a great evil.

This is certainly not Syzigia afflicta of Grote ; but I strongly suspect it to be Diludia 

 brontes badly figured.
