Lepidoptera of the Amazons. 321 
great lepidopterist has failed to recognise the real 
differences between genera which he himself described. 
Two other species, Gynopteryx ? calexaria and G. ? 
tcaunaria, rust also be referred to Cratoptera ; the Apicia 
prostypata of Snellen is a Gynopteryx, his A. plebeiata 
being characteristic of Apicia. 
GYNOPTERYX, Guenée. 
10. Gynopteryx vulgaris, Nn. 8. 
Allied to G. arbuaria (Apicia arbuaria, W1k.), greyish, 
reddish or yellowish brown, densely mottled with fine 
erey striations; two bright rust-red or reddish brown 
lines of the usual form ; the inner one restricted to the 
primaries rather more irregular and nearer to the outer 
line than in the other species; the outer line acutely 
angulated and bounding a partly white and partly black- 
edged arched costal spot near apex; the area between 
the two lines paler than the rest of the wing; a black 
disco-cellular spot; a zigzag discal series of more or 
less distinct whitish-edged grey spots; secondaries with 
the discal series of spots extremely indistinct ; under 
surface whitish or pale rusty-brown, mottled with grey 
striations ; with conspicuous black disco-cellular spots ; 
a testaceous stripe just beyond the cell; a zigzag sub- 
marginal series of whitish-bordered grey spots scarcely 
indicated on the secondaries, excepting by a darker 
shade of the ground colour; apex of primaries whitish ; 
expanse of wings, male 1 inch 1 line, female 1 inch 
2 lines. 
Male, 8. Guajara, mouth of Rio Purus, 6th September ; 
male and female, Gepatiny, 26th and 29th; male, 
Mabidiry, 80th; Urucuri, 2nd October; female, Curi- 
mata, Rio Jurua, 80th ; Pupunha, 1st to 7th November ; 
Gaviao, 10th; Rio Javary, 2nd December, 1874. 
Dr. Trail obtained five males and ten females of this 
species; it varies much in tint, but the modifications 
not only occur in different localities, or at different 
times, but also in specimens taken together, so that they 
cannot even be separated as local races.
