The $ of this species, like those of /I rjara(/i(?s, Hippuson, Vert umnus and olhers, 

 varies in the white spot of the fore wing, which is sumelimes wanting altogether. 

 This, together with its proper male heing unknown, has given rise to much con- 

 fusion in the synonymy. The varieties of the , however, are nearly constant 

 according to locality. The Surinam form has generally an obscure small white 

 spot; at Cayenne a great many have the same spot (Jardin des Plantes, as Fan- 

 thnnus 2 ). hut there occur others with a larger spot divided in two by the 2nd 

 median nervule (Boisd. Sp. Gen. p. 290). On the Upper Amazon every J , with- 

 out exception, is spotless ; at Villa Nova, on the I^ovver Amazon, most of them 

 are spotless but iheie occur a few with a slight trace of while spot. At Para, 

 and on the Tocanlins, where the species abounds, every individual has a very large 

 white spot, almost always entering the cell. As the male in the latter locality 

 shows genenilly a broader and brighter green spot of the foie wing, it is here 

 tieated as a local sub species of Lijsander, and may be considered as a tolerably 

 constant and fixed form. The spotless, or small spot J , has generally been con- 

 sidered as the 2 of Panihomis. Panthnuui, however, does not occur on the 

 Amazon. 1 have seen examples of both sexes from Demerara, the 2 resembles 

 closely the $, and can very readily be distinguished from Arhales by the shape of 

 the red spots of the hind wing. The Arbates of Cramer is decidedly not the 2 "' 

 Panthdiius. Lysaiider is found very abundantly at Kga and St. Paulo on the 

 Upper, and at Villa Nova on the Lower, Amazons. Parsotles is confined exclu- 

 sively to the district of Para. They prefer the most humid parts of the forest, and 

 fly heavily. Parsodes especially delights in the swampy palm groves which clothe 

 the numberless islets at the mouth of the Tocantins.

Var. 2 ? Gray, Cat. p. 55, pi. 10*, f. 1 (as Spartacus, Dd.) 



This species appears to occur in no other country except the lower pait of the 

 Amazon. It is the commonest of all the species of its group at Para, and re- 

 occurs at Santarem, on the southern shore of the Lower Amazon, but less abun- 

 dantly. On the noithern shoie, at Serpa and Barra, it is represented by P. 

 Er^eleles. At Cayenne, however, there occurs a form intermediate between the 

 two, as will be mentioned presently. Echelus prefers the diier districts in the 

 forest, and flies in company with P. Hteioclts. It delights to settle on flowers, 

 especially the pendulous spikes of flowers of Combreiaceous plants, which hang 

 from the overarching trees in the narrow alleys of the forest near Par4.
