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

 of larger pointed curves, anteriorly whitish, 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 

 margin, from tlie 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 occasionally 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 interneural space, anteriorly and posteriorly touches the costal and subcostal for its entire breadth, is 

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

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

 of small white spots. Central eye-si3ot similarly developed, only somewhat shorter, behind it sometimes a 

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

 marked. Distal margin of the hindwing strongly undulate." The ,^,j' from Surinam in my collection are not 

 identical with sti/gidiiii.s Btlr. from Honduras, differing 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. ^ (anaxarete Stoll $), which has strikingly small spots on the forewing anaxaretc. 

 and relatively large triangular markings on the hindwing. 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 Hubner also represents 

 a (^ similarly small-spotted it would seem that for some time only such peculiarly coloured, aberrant speci- 

 mens were brought to Europe from some particular locality. — . m&xAoni{\% suhs p. nov. (62 b) closely approaches mardon'ms. 

 anaxarete 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

 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 sjjots, 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. Muller). — faenius suhsp. 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, ir-regularly shaped greenish 

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

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

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

 generic diagnosis. From three (^(^, two $$ from Gandelaria in coll. Fruh.storfer. According to Mabilde 

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

 and Febniary, and again July and August, on Ananas and bananas. It changes into a green pu])a in March 

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

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

 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-

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