This excellent observer has shown that in some districts of South America, where, for instance, an Ithomia abounds in gaudy swarms, another butterfly, namely, a Leptalis, is often found mingled in the same flock; and the latter so closely resembles the Ithomia in every shade and stripe of colour, and even in the shape of its wings, that Mr. Bates, with his eyes sharpened by collecting during eleven years, was, though always on his guard, continually deceived.
Hautemaile bikain honek frogatu duenez, Hego Amerikako zenbait eskualdetan, Ithomia aldra deigarriak ugari diren tokietan adibidez, beste tximeleta bat, Leptalis bat hain zuzen, aurkitu ohi da maiz aldra horien barruan nahasirik; eta azken tximeleta honek bere marra eta kolore ñabardura bakoitzean eta bere hegoen forman ere Ithomia-ren hain antz handia du, non Bates bera ere, hamaika urtetan zehar bildumatzeari ekinez begia zoli izan arren, txitean-pitean erratzen baitzen, beti arretaz ibilirik ere.
