492 CALLITHEA. By J. Robee. 



smkai. C. srnkai Hour. (99 c) from the Ui^per Amazon is very similar to degandii, but ha.s a broader green 



jnargin and a A\onderful sapijhirc-blue gloss of the iipjjer surface. On the under surface of the forewings the 

 black markings are greatly reduced. 

 mlvini. C. salvini Sfg7\ from Iquitos is also similar to degandii (99 f). but the upper surface is of nearly the 



same beautiful blue gloss as in srnkai (99 e) and has just the same metal-green distal margins as the latter, 

 but the apex of the forewings itself is also of this colour. Beneath the basal part of all the wings is orange-red, 

 the under siuface is otherwise similarly marked as in degandii, the inner margin of the forewings, however, 

 is broad and deep black. 

 whitcliji. C. whitelyi Salv. (99 e) from Peru is above very similar to depuiseti (99 d), but it lacks the shaggy 



hah- in the discocellular of the hindwings, the whole hindwing except the greyish-green margin, therefore, 

 showing blue gloss. On the under surface of the forewings are 5 submarginal black spots decreasing in size 

 from behind to the front; the red colouring at the base of the wings is lighter than in deptiisefi, also some- 

 what broadened, especially on the forewings, and the inner black line is divided into large black spots. 

 lugciis. C. lugens Drc. from Peru (Cuzco) is described thus: (J head, antennae, neck, shoulder-covers, thorax 



and abdomen black. Forewing very similar to that of C. oidima (99 d), but much more lustrous blue, the black 

 apical margin much broader; hindwing much more lustrous blue, than in optima, the blue colouring procee- 

 ding exactly from the base as in whitelyi (99 e); the greenish distal margin is much broader, too. Under sur- 

 face resembles that of C. optima (99 d), but without the black lines and with very much less red at the base 

 of the hindwings, but with much more red than in leprieuri (99 d); a large round red spot at the cell-end; 

 the forewings have a submarginal row of 5 rather large black spots. • — Although the author compares this 

 sjDecies with 2 species belonging to 2 different groups of species, yet the remark that the blue of the hind- 

 wings begins at the base of the wings as in ichitelyi, shows evidently that lugens belongs into the group A 

 and the nearer affinity of whitelyi. 



B. cJ o n the u jj p e r surface of the hindwings in the discocellular with 



shaggy hair. 



leprieuri. With C. Icprieuri Feisth. (99 d) from Surinam and the Lower Amazon, commences that series of species 



in which the (J shows long black shaggy hair of the discocellular on the upper surface of the hindwings; 

 for these species C. Felder has established the genus Gyane which is distinguished especially by shorter 

 antennae and longer, stronger jjalps. C. leprieuri shows a dull blue gloss on the upper smface, being intensified 

 on the basal part of the forewings, in the $, however, only indicated. 



depuiseii. C. dcpuiscti Fldr. (99 d) from Peru resembles leprieuri, but has a more intense blue gloss of the upper 



surface, which extends also to the hindwings. The greyish-green marginal band of the upper surface is much 

 broader and lighter than in leprieuri, tffe under surface is quite similar as in the latter, the forewings, however, 

 cmlia. showing less black markings. — Rather different is the Bolivian form which we call eudia form. 7iov. It has 

 much broader, also lighter greyish-green margins and a more intense blue gloss of the upper surface. On 

 the under surface of the hindwings the golden gloss is confined to the median band in which the black 

 sjaots are placed, these spots are soiiiewhat larger, the distal (submarginal) black line being bi'oader and also 

 the red basal spots somewhat more extensive. 



philiifima. C. philotima Ebl. „^. Nearly allied to C. depuiseti Fldr., optima Btlr. and whitelyi Salb. Differing 



from the former two by a much broader, pale metallic-blue margin of all the wings. The black marginal line 

 is much finer than in depuiseti, also the apical part of the forewings is less extensively black. The fringes 

 are snow-white along the margin of all the wings. The jet-black long scent-hah' in the disc of the (J-hind- 

 wings as in depuiseti. — The under surface forms by the disposition of the red basal spots an intermedium 

 between depuiseti and optima. The forewings exhibit a short blood-red basal streak of the costal margin and 

 only 1 black subapical dot in cellule 5. At the base of the hindwings there are 3 blood-red long spots, one towards 

 the costal margin and one towards the inner margin, and one long tooth-like spot in the upper half of the 

 discocellular, the sharp point of which is situated about in half the lenght of the discocellular. Also at the 

 black transverse vein of the discocellular there are a few red scales. The black macular markings quite 

 similar to that of depuiseti, which entirely lacks the long red spot in the discocellular, whereas optima shows 

 the whole basal area of the hindwings (except a bluish-black spot in cellule 8) of a miniate colour. C. 

 whitelyi has only at the base of the discocellular of the hindwings red spots; the first transverse line of it is 

 broken up into short longitudinal spots. 1 (^ from the Chanchamayo." 

 opihiia. C. Optima Btlr. (99 d) from Peru and Ecuador is somewhat smaller and has more pointed forewings 



than depuiseti, but much more intensive blue gloss and narrower greyish-green margins of the upper surface. 

 Nearly the basal half of the under surface of the hindwings is miniate, the rest of the markings, however, 

 cm i liens, very similar to those of leprieuri. ■ — eminens form. nov. (99 e) from Southern Peru (Upper Madre de Dios, 

 500 — 1200 m) is remarkably different from optima, but nevertheless probably a local form of this species. It 

 has been discovered by Mr. A. H. Fassl. The greyish-green margin is on all the wings considerably broader, 

 about three times as broad as in optima, therefore the area of the blue gloss is considerably diminished, 

 the black spot in the centre of the forewings, which in optima is very conspicuous in most any direction
