Drury referred this insect to the then unpublished Papilio Hydaspes, on the authority 

 of Fabricius's handwriting, (his specimen having most probably been thus labelled by that 

 author.) The authors of the Encyclopedic Methodique also cite Drury's figure under 

 Hydaspes. Fabricius, however, cites only the Banksian Cabinet, and Mr. Donovan's 

 figure taken from the Banksian specimen, and published in the Naturalist's Repository, 

 Vol. '2. PI. 60. convinces us that Drury's insect is specifically distinct from that described 

 by Fabricius, although evidently identical with the insect described as Hydaspes in the 

 Encyclopedie Methodique. 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, fi'om 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 diiferent from that figured by Donovan.

Upper Side. Antennae black at the base, but yellow at the extremities. Thorax and abdomen 

 greenish brown. Anterior wings angulated, and black, but orange-brown at the base ; posterior edges 

 verged with black. An irregular indented yellow bar crosses them from the middle of the anterior 

 edges to the middle of the external ones; and near the tips are placed two white spots, one large, of an 

 oval shape, and a small round one. Posterior wings with two tails, chiefly of a yellow-brown colour, but 

 having a black circular patch placed along the external edges, and reaching nearly from the abdominal 

 to the upper corners, whereon are placed three white crescents and a small round spot. 



Under Side. Palpi yellowish. Tongue dark brown. Legs yellowish. Breast dark brown. Abdomen 

 yellowish. Wings ornamented with such a variety of soft colours, as renders it impossible to describe 

 them minutely. 



The transformations of this curious species have been figured by Stoll in his supple- 

 mentary volume to Cramer. The caterpillar is of a dark green, with a black dorsal line 

 and lateral spots of the same colour. The head is black, with two yellow spots, and 

 furnished with two short obtuse spines. It lives upon a plant called " poirvier," feeding
