LEPIDOPTERA. 101 



Papilio Dorimond. StoU, Suppl. a Cram. pi. 37. fig. 4 and 4 D. (The female.) 

 Polyommatus Apidanus. MM. Latr. et Godt. Enc. Meth. Hist. Nat. ix. 652. 

 Wings above, in the male, covered on the whole surface, excepting a very narrow posterior black 

 marginal thread, with a saturated purple tint, reflecting in a certain light a cyaneous gloss, or 

 transmitting in another aspect the blackish ground colour with a faint livid lustre ; in the female 

 the wings are blackish brown, with a brilliant cyaneous patch, adorned with a rich silvery gloss of 

 a more intense tint at the base, and defined in both pair according to the outline of the wing, being 

 separated from the margin by a broad regular border of the blackish-brown ground colour. Under- 

 neath the wings are alike in both sexes ; the ground colour is deep brown with a reddish cast, and 

 marked with broad cinereous slightly yellowish bands, and with occasional pearly spots ; the tips of 

 the fore wings and the whole surface of the hinder, being covered with a purple reflexion ; the 

 wings bear individually, at the base, near the costa, an oblique attenuated streak of a deep crimson 

 shining tint ; the anterior have further three grayish bands, of which thefirst is abruptly terminated 

 before the disk, and often appears in the form of a short stigma, the two others are terminated 

 in the anal region at a small distance fi'om the inner margin ; the exterior band is often unde- 

 fined and spreads diffusely to the margin ; in some specimens a few minute grayish dots stand 

 near the base ; in the posterior wings the basal portion is dark brown ; a broad cinereous band, 

 highly tinctured with purple, occupies the medial portion, bearing a compound brown band 

 faintly bordered with gray, consisting in the costal area of a short simple brown patch to which 

 two parallel bands are joined, the anterior being interrupted the posterior continued and united 

 with a deep ferruginous blackish brown band which passes in an arch across the disk ; exterior 

 of this are a few obsolete dots near the posterior margin being defined internally by a narrow 

 waving blackish striga ; the dots towards the outer apical angle are very faint, but in the anal 

 region are two pronounced black subocellate spots, the exterior being placed between the tails, 

 and the other which is largest, at the extreme anal angle ; they are generally speckled with 

 white within and at the sides and in some cases adorned with a few silvery spots. The body 

 is deep blackish bi-own or purple above, and ferruginous brown and hairy underneath ; the 

 antenncB are nearly throughout ferruginous brown ; the intermediate tail is narrowly tipt with 

 gray. The tarsi of the male are covered above with small, and of the female with large scales, 

 which appear pendulous under the lens. 



Amilypodia Apidanus appears, agreeably to my observations, to be the most abundant species of this 

 section. Our museum contains at least sixteen individuals, three-fourths of which are females. Most of 

 these were obtained while I was carrying on my observations on the metamorphosis of Javanese Lepidoptera. 

 The larva feeds on the leaves of several species of Eugenia and Calyptranthes. It occurred not 

 unfrequently, and was from time to time undergoing its change in my breeding cages. Observing some dif- 

 ference in the individuals, which I ascribed to the difference of age, the subject was more than once 

 delineated ; the forms under which I observed it are represented in the third and fourth figures of the 

 fourth plate. On arranging my materials for publication, and examining them with more minuteness than 

 was practicable during a very extensive series of inquiries, I discovered our 30th species, Amblypodia 

 Narada, mixed with a large number of individuals of Amb. Apidanus, obtained by breeding, and designated 

 by the same mark. It now was manifest to me, that what I had considered, in the larva state, a mere variety 

 of form, owing to the age of the individual, was in reality a different species, modified in the perfect insect, 

 in the character of the wings and affording the type of a separate section in the subgenus. But, although 

 this fact was apparent, yet the general agreement of the two larvae, as well as the respective chrysalides, 



confirmed
