SOS OPSIPHANES. By H. Pruhstorfer. 



but the band is paler in colour, occasionally likewise washed-out and somewhat darkened, always narrower 

 than in the type-iorm; it remauis as a rule somewhat removed from the end of the cell, more rarely slightly 

 touching it at the origin of the lower radial. Hmdwing in the S nnicolorous or only with indistinct or clouded 

 remains of the marginal band ; in the $ the posterior part of this band is present, but dull, anteriorly it is obsolete 

 Ulas. or transformed into small dull spots. Guiana and Lower Amazon. — midas Stick. Type from Coca in East 

 Ecuador. S: ground-colour dark black-brown. Band of the forewing less shai*ply bent than in the t3rpical sub- 

 species, forming at the proximal boundary only a slight curve, at the distal an obtuse angle in the upper 

 median cellule. Proximally it is but little incised at the vems, at the middle median occasionally somewhat 

 more strongly, distally it is more broken and less sharply defined. In the hinch\'ing there is a narrow rust- 

 yellow distal band, which starts posteriorly in a point, m the hinder angle immediately adjoins the distal 

 margin, and is there broadest, about 4 — 5 mm., is then removed to about the same distance from the margin, 



luxiiriosa. narrowed and broken up into spots. — luxuriosa Stick. cJ: differing from the preceding in having the band 

 of the hhidwing only present as a broad rust-yellow spot in the anal angle, about from the submedian to the 

 upper median. The distal margin otherwise unicolorous. Band of the forewing broad, the distal boundary 

 somewhat dentate and angled, the proximal likewise hicised at the veins, filling the upper jijart of the cell. Ocelli 

 on the underside of the hindwmg large and brightly marked. Each surrounded by a broad rust-yellow patch, 

 the patches connected so as to form a sinuoiis undulate band, in which the ocelli are placed. Length of the fore- 

 wing 49 — 50 mm. $ larger than the ^, ground-colour lighter. Band of the forewing extending considerably 

 into the distal part of the cell, so much so indeed, that the latter is filled up with rust-yellow from the upper angle 



viccnciona. to the origin of the middle median. Length of the forewing 54 mm. Colombia (^luzo ?). — vicenciona subsj). 

 nov. somewhat resenihlesunditaema above in the band of the hindwing, on the other hand that of the forewing, as in 

 luxuriosa Stick. , touches the ajiex of the cell, but is distally even somewhat more broken and anally narrowed. Before 

 the cell-wall, just at the origin of the lower radial, stands a circular spot, which is not broadly diffuse as in 

 luxuriosa. Subtermmal band of the hindwmg deeper reddish yellow than in unditaenia, anteriorly^ not broken 

 up into separate spots and anally extending to the distal margin, thus somewhat widened. Under surface: 

 cells red-brown, but the apical part and the whole submarguial area of the forewing grey-violet, hindwing 

 with four green-pupilled posterior eye-spots and two anterior ones filled up with reddish. East Colombia, Villa- 

 adjecta. vicencio, 400 m. (Fassl leg.). — &A\iC\a Stick. (J above deep black-brown. The band of the forewing proxim-ally 

 touches the discocellulars and is gently bent, not angled as in the typical subspecies, also somewhat broader 

 on an average. Distal marginal band of the hindwing towards the hinder angle considerably widened, anteriorly 

 narrower, at the apex tapering to a point and in the anterior half somewhat removed from the margin. The 

 bands of both wings bright reddish ochreous. Under surface, as in the following subspecies, brightly coloured, 

 the distal eye-spots occasionally developed into a complete chain across the entire breadth of the wing. Bo- 

 herecyn- livia, Amazons (m transitions). — berecynthina Hopff. {= vercingetorix Stgr.). ^: band of the forewing proxi- 

 ihina. jnally widened m such a way that the angle is completely filled in and the boundary-line runs in a curve. The 

 proximal boundary occasionally crosses the distal part of the cell, the discocellular, however, remaining brown. 

 In this case its margui is incised at the median and anteriorly m the cell vaguely dusted. At the distal boundary 

 the angle in the upper median cellule is, however, more distinct. The posterior part and the point at the extre- 

 mity are much broader than in the typical subsi^ecics. Hindwing at the distal margin with an entire-marghied 

 band, which starts in a point at the hmdmargin, quite near the hinder angle, soon widens to a breadth of 

 8 — 9 mm., anteriorly is gradually narrowed again and somewhat removed from the margin, and terminates 

 almost in a pomt in the apical area. In transitional specimens the band is narrower in the posterior part, the 

 narrowing less gradual and the anterior part more or less broken up mto spots. $: the band of the forewing 

 crosses the distal part of the cell, at least its posterior angle; band of the hindwing similar to that of the (J, 

 but still broader, up to 12 mm. The bands of both wings paler in colour than in the ^, the brown ground- 

 colour also less deep, the eye-spot of the under surface between the radials of the forewing showing through 



unditaenia. strongly above as a filled-up black circle. Pei-u, Bolivia. ■ — unditaenia Fruhst. (64 a) was already known 

 to HiJBNER and figured by him as berecyntkia. But Hubner's and our figures differ considerably from Cra- 

 mer's name-type: 1) in having the band of the forewing not elbowed or angled, but forming a neat curve; 

 2) in the broader and more intensively red-yellow bands of both wings; 3) in the brighter red-brown under 

 surface. These three differences at once characterize the new local form which has not hitherto been noticed 

 and in which the bands are almost as much widened as in the ty]3ical herecyntkidCr. $$, but brighter coloured 

 and more shai-ply defined. I have seen no examples in which the black border occupies the entire distal margin, 

 as in HtJBNBR's figure. In my Rio SS this border only reaches to the upper median; this and some other varia- 

 tions are naturally unimportant and mostly individual. In respect of the tertiary sexual characters, unditaenia 

 differs from the type in four modifications: 1) the much longer and denser hair-tuft at the inner margin of the 

 forewing; 2) the scent-pencil at the upper cell-wall of the hindwing much stronger and completely covered 

 by this hair-tuft ; 3) the entirely black hair-pencil (in herecynthia basally yellow); 4) the longer hair-tuft in the 

 shiny scent-cavity of the submedian. Coll. Fruhstorfer, type 1 c? from Rio de Janeiro, accordhig to Stichel 

 1 example from Sao Paulo in coll. Staudinger.
