beyond the half-band large, elongate, distally uncertamly defined. Zigzag band of the hindwing composed 

 of larger pointed ciirres, anteriorly \^'hitish, posteriorly grey-yellow with olivaceous tone ; costal margin broadly 

 whitish yellow; border at the distal margin narrow but distinctly defined, anteriorly coloured like the costal 

 margm, from the middle onwards grey-yellow. Under surface of the forewing with small, sharply marked, 

 elongate black costal spot immediately at the apex, the half-band very little noticeable, the three isolated spots 

 more indefinite, the posterior one occasional!}^ cleft longitudinally. Anterior eye-spot of the hindwing extra- 

 ordinarily broad, flattened, rectangular with the short sides rounded. It occupies nearly or more than one third 

 of the intemeural space, anteriorh' and posteriorly touches the costal and subcostal for its entire breadth, is 

 at these long sides onlj" distinguished from the ground-colour by the absence of the striation, but at the 

 short sides shaded with dark brown ; its central part is longitudinally somewhat darker and traversed by 2 lines 

 of small white spots. Central ej^e-spot similarly developed, only somewhat shorter, behind it sometimes a 

 white-centred ring-spot. Posterior eye-spot as m the typical subspecies, but mostly larger and more sharply 

 marked. Distal margin of the hmdwmg strongly undulate." The c?(J from Surinam in my collection are not 

 identical with stygianus Btlr. from Honduras, differmg in the somewhat narrower whitish yellow band and the 

 smaller patches on the forewing, also in the darker, deeper coloured under surface. But still less do they 

 agree with the figure of anaxarete Cr. q (anaxarete StoU 9), which has strikingly small spots on the forewing anaxarete. 

 and relatively large triangular markings on the hindwmg. In the $ which Stoll figures the oblique band of 

 the forewing is even broken up into separate small spots hardly as large as lentils, and as Htjbnbr also represents 

 a o s imil arly small-spotted it would seem that for some time only such peculiarly coloured, aberrant speci- 

 mens were brought to Europe from some particular locality. — ■ mardonius subsp. nov. (62 b) closely approaches mardonius. 

 anaxaret-e Cr. in the narrower, almost uniformly broad band of the forewing, and also agrees with it in 

 the shape of the nearly rectangular costal patch on the underside of the hindwing. On the other hand the 

 zigzag band on the hindwing above is twice as broad and the under surface, in accordance with the general 

 character of the Paraguay butterflies, is paler and without the purple dusting of anaxarete. Paraguay, from two 

 $2 in coll. Feuhstorfer. — • darius F., described from Brazil, is the commonest subspecies in collections; darius. 

 both sexes bear a relatively large double patch of greenish white on the upperside of the hindwing, on which are 

 placed regular series of undulated, greenish, pointed curves. $ sometimes enormously large. Espiritu Santo,

 type-form, the band and the three isolated spots on the forewing yellow instead of whitish. Zigzag band of the 

 hindwing and a narrow marginal stripe at the distal margin anteriorly yellow, posteriorly dirty green-yellow. 

 Larva yellow-brown, later grey-brown or green, longitudinally striped, with brown head, which in the adult 

 larva bears short hairs at the margin. Along the dorsum a series of round dark spots, enclosing light dots 

 anteriorly; small, bristle-bearing tubercles are scattered over the surface and the anal end terminates in a forked 

 tail. On Bromeliaceae ; full fed in 2 months. Pupa light green with brownish longitudinal stripes and dark 

 shades and speckling; yields the butterfly in 12 days (W. MtJLLER). — faenius subsp. nov. inhabits Rio Grande faenius. 

 do Sul and is somewhat smaller than darius from Central Brazil, with somewhat smaller median spots on the 

 upperside of the forewing, and the hindwing lacking the large yellowish white costal patches, in place of which 

 there are greenish diffuse spots, which do not differ appreciably from the adjoining, irregularly shaped greenish 

 pointed curves. The under surface agrees somewhat with that oi mardonius ; it shows the typical paler colour- 

 ing of all the Rio Grande biitterflies. $ dusted with almost pure white, particularly in the distal area. All the 

 ocelli obsolescent, the median eye-spot in most examples entirely absent. Glasping-organs described in the 

 generic diagnosis. From three cJ(J, two $$ from Candelaria in coll. Fruhstorfer. According to Mabildb 

 there are two generations. The larva is green with two figure-shaped marks on the head and appears in January 

 and February, and again July and August, on Ananas and bananas. It changes into a green pupa in March 

 — April, and August — September, and after 30 to 60 days produces the common and widely distributed butterfly. 



D. macrosiris, in contrast to the preceding species, is extremely rare ; only a few examples are known, 

 mostly of only one sex. — • macrosiris Weshv. comes from Cayenne; it is black above with a slight violet- macrosiris. 

 brown tinge, the distal border lighter, costal margin striated with black and white. The oblique band of the fore- 

 wing, placed distally to the cell, is narrow, whitish, terminating at the first median vein, but continued as two 

 small, isolated whitish spots. Distally to the oblique band two black, lighter-margined spots showing through 

 from beneath, anteriorly with two small, crescentic or obtusely sagittate white spots placed near the apex. Hind- 

 wing with lighter distal border, towards the apex widened into a whitish spot. — Of strix Bates (62 b) only sirix.

 by HoGE. Our figure is from a Honduras specimen in the Fruhstorfer collection. Deep dark brown, costal 

 margin of the forewing striated with white as far as a whitish oblique band placed beyond the cell, continuing 

 which there is an elongate white spot. In the apical area 3 small white spots. Hindwing with whitish apex, other- 

 wise uniformly dark. Under surface very characteristic, particularly in the irregular shape of the ocelli between 

 the apex of the forewing and the oblique band. — hannibal Oberth. came from Colombia and differs in havmg Mnnibal.
