It is doubtful, however, whether the drawing of the veins has been sufficiently attended to, to offer any reliable characters. In this paper he quotes Boisduval’s locality “Aix en Provence,” but when he next refers to this insect[P] he gives it as from “Aix-la-Chapelle, White sandstone,” a mistake, however, corrected subsequently. In this latter paper he remarks: I have discussed the position of this species in my catalogue of Satyridæ, pp. 189, 190; showing that its nearest ally is _Neorina Lowii_, a common Bornean species, but that it also has a slightly more distant relationship to _Antirrhæa Philoctetes_ and _Anchiphlebia Archæa_, two common tropical American forms; the amount of affinity, as regards the first two of these species, may be seen on my plate, figs. 4 and 5; the resemblance to Anchiphlebia is less striking, and the affinity more doubtful; it has nothing to do with Cyllo. That Butler should have so nearly pointed out the exact affinities of this insect from the simple study of Boisduval’s plate, is unquestionably due to his extended familiarity with butterflies, and especially with the forms of this subfamily; but it also shows the essential harmony between the markings of the under and upper surface of the wings of butterflies, notwithstanding their frequent great dissimilarity; for Butler compares this fossil with the recent forms on the assumption that the under surface of the wings is seen in Boisduval’s plate.
