hindwing with distinct whitish rings in the anal region. Philippines; according to Semper, the discal spot grows 
darker in southern specimens, and also in northern ones it varies greatly; these southern specimens Fruhstorfer 
denominates mindoraraus. — orsiphantes Fruhst. (158 c). This form shows a more intense blue gloss on the upper mindora- 
surface in the <$, whilst in the $ the discal brightening in the forewing is slightly powdered, and spotted with . f 
brown; in the hindwing before the marginal rings small yellow lunae. Bazilan. aimnestus Fruhst. is the aimnestus.' 
Palawan form: the bluish-white spot in the disc of the forewing is still more hazy than in orsiphantes. Forewing 
beneath more greyish-green than in the light greyish-white northern races from the Philippines. — Finally 
the species also occurs in the Gulu Is., where the under surface is said to be of a more brownish tint than in 
Malacca: — georgius Fruhst. — Larva green with an indistinct' dark dorsal line and 2 subdorsal lines which georgiu *. 
are united at the anal end. It lives on Vangoeria spinosa and is guarded by ants. Pupa green, sometimes with 
brown spots. The imagines are common in many places of their enormous range. The ^(jlike to settle on wet 
places in the roads and are therefore frequently captured. 
H. phorbas F. (158 c). The Australian (typical) form of this beautiful species has in the quite blue, phorbas. 
lustrous wings; only an oval scent-spot at the cell-end; the margins of the wings and the veins are black. The 
$ is dark brown with a white disc on both wings. According to Waterhouse and Lyell both the sexes vary 
a great deal individually; e. g. the white discal spots of the $$ may be of very different sizes, and the 8$ 
may have a dark greyish-green ground-colour (ab. noctula Stgr.). — In dictaea Fldr. the under surface is almost noctula. 
purely white, and the Thecla- streaks being distinct in silo Fruhst. (158 d) are beneath quite absent. Besides, ^jj^ aea ' 
the $ of dictaea shows in the hindwing instead of the white disc a group of light brownish spots, dictaea comes 
from Waigeu. In silo from New Guinea there is below the black scent-spot in the disc of the forewing a whitish 
oval brightening. The $ of silo is without any brightening in the hindwing, so that I presume that the $ having- 
been figured (158 d) as ,,pseudophorbas“ is nothing else but a silo-Q, although it originates from the Salomons 
Is., where silo probably occurs, too. - infumata Fruhst., from the Volcano Island, differs from typical phorbas infumata. 
in the upper surface of the forewing being covered with almost entirely blackish-brown scales (instead of being- 
dark blue, and from silo from New Guinea in the absence of the white brightening along the submedian line 
of the forewing, from both besides in the bluish-grey instead of whitish under surface of both wings; it is allied 
to puella Bsd. — montoni Rbb., from New Lauenburg, is smaller than periphorbas and trnolus ; the $ resembles montoni. 
that of periphorbas, but the white spot of the forewing is hardly traceable; in another $ form flying together 
with it this discal spot is entirely absent. Both wings above with an intense blue iridescence. Under surface 
lighter than in periphorbas. — periphorbas Btlr. resembles the tmolus-iorm of erylus (146 Be), but above in periphorbas. 
the $ the white spot of the forewing is smaller, not bluish. Hind wing shorter, not so grey with 4 well defined 
black submarginal spots bordered with whitish. Under surface not so purely white, cell-end and transverse 
band ochreous. New-Britanny. — pseudophorbas Fruhst. (158 d), from Biak, is very similar to the form irom pseudophor- 
the Island of Ron, which is very distinctly separated from typical $$ of phorbas by the hindwing above entirely 
lacking the white discal spot, whilst that in the forew-ing is very much reduced. 
H. sipylus. Both sexes show above a dark brown ground-colour, and in the hindwing whitish marginal 
and anal regions covered with light blue, with black spots before the margin. Also the under surface is whitish- 
blue; in the forewing the margin is brownish, the cell-end and a chain of streaks behind it nebulous dark; the 
hindwing is analogously marked. All the markings beneath are tinted rusty yellow-. The form described first: 
sipylus Fldr. (158 d) originates from the Moluccas and is not rare in Ceram and Amboina. Here the, anal area sipylus. 
of the hindwing above is narrower and of a bright light blue, proximally irregularly defined. — gis^on Fruhst. gis&n. 
(158 d) is beneath darker, the apical portion brownish instead of w-hite, the black spots are more prominent. 
North Celebes. rhodanus Fruhst., from South Celebes, is larger, above lighter blue, the light anal area more rhodanus. 
extensive; — in nurua Fruhst., from Sumbawa and Flores, the under surface is more yellow than white, the numa. 
submarginal maculae are finer, more uniform. — capella Fruhst. Here the blue area of the hindwing above is capella. 
crossed by a black sub marginal band. In the ^ the light anal spots in the hindwing are powdered, rather 
indistinct. Lombok. pictor Fruhst. (158 d). The anal area of the hindwing above is broader, towards the victor. 
centre of the wing more extensive, also lighter, whiter, only near the proximal border more intensely blue. 
Waigeu. — tharrytas Fldr., like pictor, shows a broader whitish-blue* anal area above than sipylus, though it tharrytas. 
differs also beneath, according to Semper very constantly. The median row of spots is straighter and narrower, 
and the spot below the costa of the hindwing behind its centre is never black-centred. Philippines and Palawan. 
— Larva green, woodlouse-shaped, on Eugenia. Pupa likewise green; it yields the imago after about 10 days. 
— Not rare. 
H. hewitsoni Drc. (= cinesia $ Heiv.) (146 B e) is very similar to cinesia Hew., but smaller; above hewitsonii. 
the white band of the hindwing is narrower and traversed by the dark veins. Under surface ochreous-yellow. 
parva Moult. (159 h) may be nothing else but a normal, somewhat small $ of it. From Borneo. pawn. 
H. cirteas 8m., from the Kina Balu, is in the $ quite similar to hewitsoni, but distinguished by the dneas. 
white anal band above not being parted by dark veins. The 8 is unknown to me, but it is probably very 
similar to the following species. Borneo.
