“ Under these circumstances I have considered it most advisable to retain the name of Hydaspes for Drury's insect, under which name it was known for the space of ten years before the publication of the Fabrician Hydaspes, to which a new specific name must be applied. As there are several other nearly allied Brazilian species, it is not impossible that Fabricius, from recollection alone, applied the name of Hydaspes to Drury's specimen, having previously described the insect from the Banksian Cabinet, the under surface of which especially is very different from that figured by Donovan. ”
