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 It is true that he might otherwise have been superseded ; but, as a fact, 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