Papilio Sloaneus. Cramer. _pl. 85. e. f. vol. 1. p. 134._ Papilio Leilus. var. _Fab. Ent. Syst. 3. 1. 22._ ---- Specimens of this rare and splendid species, sent to our museum from the island of Jamaica, enable us to complete the illustration of the only three American species of this type hitherto discovered. It is in all probability the same as that figured by Cramer; particularly as his specimens came from the same locality. Even a superficial comparison of this figure with those on our two last plates, will shew the error of Fabricius and others, in classing them all under the same name. We have represented the species in that attitude which is assumed by _L. Braziliensis_, when at rest; the wings of which species are sometimes _less_ but never _more_ expanded: the fruit, upon which the insect is reposing, is the common West India _Banana_, shewing its natural size. In drawing the attention of Entomologists to the anatomical details of this typical example of the genus _Leilus_, it will be readily perceived that the obscurity which has involved its natural affinities, has entirely arisen from ignorance of its structure. At a time when minute and obscure Coleoptera are submitted to the most delicate dissection, under powerful magnifiers, the LEPIDOPTERA, not only the most striking and splendid of all insects, _but the pre-eminent type of the_ ANNULOSA, have been comparatively neglected. We cannot otherwise account for this, but by remembering that the influence of fashion is universal, and that she is always followed by the majority. This exclusive devotion however, to one order, is highly detrimental to the study of the natural system; or with so many profound Entomologists who have gone before us, it would not have been left for us to make known the fact, that the sub-family _Papilionæ_, represents the sub-family _Harpalinæ_, (Harpalidæ, _Auct._) And that this analogy is not only demonstrable by the peculiar construction of their _tibiæ_, but by the parallel relations and by the circular affinities of the COLEOPTERA and the LEPIDOPTERA. * * * * * * [Illustration: LEILUS _Orientalis_. _Sw._] LEILUS Orientalis. _Oriental Emerald Butterfly._ ---- SPECIFIC CHARACTER. _Posterior wings six tailed; anal angle with a large flame-coloured space, varied with black spots; tails unequal, whiteish._ Papilio Rhipheus. _Cramer, Vol. 2, page 193, pl. 385, fig.

On this and the next plate we have copied two figures of insects which we have never seen, for the purpose of bringing them immediately before the eye of the entomologist, and of clearing up some remarkable facts concerning them.
