The figure of Espet* does not show the pointed lobe in the middle of the nnnrgin 

 of the hind wing, vthich, indeed, is indisdinet in some individuals; otherwise it 

 represents accurately the insect figured by Gray as Cyamon J. The $ was le- 

 ferred by Boisduval to the Ilus of Fabr., but it is easy lo see liom the dericiiption 

 of Fabr., where he gives the fore wing beneath as immaculate, and the hind wing 

 as having four red spots at the base, that lie had in view a quite diffeient species. 

 The figure in Jones's drawings (of which .Mr. Westwond kindly showed me a 

 tracing) agrees with the Fabrician descripiion, which, indeed, tepresents an insect 

 that I have not yet seen in any collection. The number of the red spots at the 

 ba<e of the wings iieneaih in tliis group is an important specific character. P. Ari- 

 arathes, with all its varieties and unfixed local sub-speries, has always two red 

 spots at the base of each wing, with sometimes an indication of a thinl in the hind 

 wing of the female. The species is one of the most unstable in its colouration, 

 and partly so in its wing-outline; the varieties aie generally, however, local, but 

 the individuals composing them are not constant enough, nor are the chaiacters 

 sufficiently well defined, to induce me to treat them as independent sub-species. 

 The individuals of the type vary amongst themselves in the same locality. The 

 ^ , as pointed out by fciichson, has a triangular, dusty cream-coloureii spot, 

 variable in size, on tlie foie wing, proceeding from about the middle of the hind 

 margin and extending ohlicpiely outwards towards the midd'e of llie wing. The 

 apex of the spot sometimes terminates at the first, sometimes extends to the third 

 median nervule. The red macular belt of the hind wing varies very much inbreadth 

 and in the number of spots of w hich it is composed. The typical form of Ariar- 

 athes 1 obtained chiefly at Para, wliere none of the local varieties above cited occur. 

 It is also found in English, Dutch and Freni h Guiana. It is a rare species, and 

 flies with great rapidity in sunny places about the borders of plantations. 



Var. Cyamon, Gray, $ , This is an extreme variety of the $ . Jt occurs on 

 the Upper Amazons. Here, the (lale spot of the fore wings, lather whiter 

 than in the type, is removed to near the outer mirgin of the wing and is pro- 

 longed into a belt. Otlier varieties are before me, showing the belt arising 

 nearer to the niiddle of the hind margin ; tluse intermediate foitns occur at 

 Ega, and lower down tl>e river at Villa Nova. Flxamples agreeing with the f 

 but none with the J of the true /)» /a) ut/ies have been found on the Upper
