306 OPSIPHANES. By H. Fruhstoefer. 



reduction in width is from the proximal side, so that the band appears to be placed nearer to the apex and 

 its angulation is more pronounced. Its general course anteriorly is oblique from the costal margin towards 

 the subapical eye-spot, which shows through from beneath, and from there in an obtuse angle towards the hinder 

 angle. The distal border itself is distinctly lighter, so that between it and the band only a narrow stripe of the 

 groimd-colour remains, and this quite ceases posteriorly, the light shade of the band and that of the border 

 here running into one another. Distal border of the hindwing narrower and duller, sometimes very little lighter 

 than the ground-colour. In smgle cases the marginal band stands out somewhat more distinctly, its bordering 

 being then strongly dentate. $ with broader, dull violet transverse band, less angled at the cell, anteriorly 

 indistinct and distally strongly notched at the veins in the vaguely dusted bordering. The eye-spot in the 

 apical part standing out very distinctly on the pale blackish ground-colour, distal margin more broadly bordered 

 with lighter smoke-brown. This border is strongly dentate and rather distinctly defined, on the hindwing 

 / narrower and paler, light bone-coloured. 



'■' rivalis. 0. rivalis Niep. is said to be very similar to xanthus L., agreeing in habitus with xanthus dohrni Stick. 



Wings somewhat narrower than in dohrni. Apex of the forewing almost pointed ( ?), distal margin more sinuate. 

 Upper surface velvety chocolate-brown. Forewing with three apical patches, after these a black ocellus showing 

 through from beneath, then posteriorly between the lower radial and the upper median a whitish yellow spot. 

 The submargmal macular band not obtusely angled but gently curved. It consists of 7 spots of unequal 

 size and of dark rust-yellow colour, mostly pointed proximally. The hair-pencil in the cell light brown, that at 

 the submedian velvety black. Under surface as in dohrni, the yellow-brown colour more intensive, the white 

 striation more pronounced, the black markings stronger. The posterior ocellus is said to be pear-shaped. Length 

 of the forewing 54 — 55 mm. Maccas, Ecuador. 

 xanthicles. 0. xanthicles, as its name already suggests, bears a certam similarity to 0. xanthus L., but the hair- 



brush at the submedian of the forewing is less broadly attached and more bushy, pencil-like, xanthicles Godm. 

 (J. Dark brown, the band of the forewing runs from the costal margin at some distance distally to the end 

 of the cell and parallel with the discocellulars obliquely to the upper median vein, is behind this bent round 

 posteriorly in an obtuse angle and gradually tapers to a point towards the hinder angle. The proximal boundary 

 is rather sharp and in places only a little notched, the obtuse angle somewhat rounded, the distal boundary 

 projecting at the lower radial, the angulation sharper, otherwise running in a fairly uniform direction. Hind- 

 wing with several small, dull ochre-yellow apical spots or the nidiments of a marginal band at the apex. 9- 

 Ground-colour of the upper surface pale grey-brown, the apical area darker. Band of the forewing broader, pale 

 ochreous. The widening occurs chiefly at the proximal side, so that the band is placed nearer to the cell and 

 the obtuse angle is lost. The boundary-liiie forms here only a slight curve, whilst distally it shows exactly the 

 same characters as in the ^. Hindwing with more distinct, pale ochre-yellow marginal band, which, however, 



cijparissa. just behind the apex is somewhat removed from the distal margm and vaguely diffused. Panama. — cyparissa 

 Fruhst. (66 a). Ground-colour black-brown, fore\vmg with the usual 3 white apical clots and with a dark 

 ochre-yellow band traversmg the wing from the costal margm (at a distance of about 7 — 9 mm.) distally to 

 the cell and about the upper median approaching the distal margin, which it nowhere quite reaches. Towards 

 the submedian the band is narrowed. On the hindwing it is continued as a moderately broad distal border, 

 extending from the subcostal to the middle median and gradually narrowed posteriorly. Before the upper 

 wall of the cell a long black hair-pencil (m xanthus this pencil is light yellow, in berecynthia black and small, 

 in amphirhoe and orgetorix it is entirely absent), a still longer, thicker hair-pencil, distally strongly wavy, 

 arising from a fold before the submedian, and the usual small grey scent-tuft in the bare scent-cavity proxi- 

 mally to the submedian. Under surface: basal half of the forewing dark brown, the submarginal area striated 

 with white, the distal border anteriorly brown, posteriorly yellowish. From the black-pupilled apical ocellus 

 onwards a narrow, sharply pronounced violet-white submarginal band traverses the wing. Hindwing with a 

 broad, oblique broAVn median band, crossmg the lower part of the cell. Round the large brown-rmged anal 

 ocellus a broad, somewhat coffee-brown patch; otherwise with dense, fme white striation throughout with the 

 exception of the greenish brown distal border. Two black undulate antemargiiial lines extend on the hindwing 

 from subcostal to submedian, on the forewing they become indistinct before the middle median. $ uniformly 

 black-brown, the white apical patches somewhat larger than in the (J. Band of the forewing nearly twice 

 as broad, only moderately narrowed costally and anally, between the lower radial and the upper median enclo- 

 smg a white dot in the distal part. Margmal band of the forewmg compact, ochre-yellow, proximally with 

 reddish gloss, sharply^defined as far as the imier marginal vein. Under surface more copiously striated with 

 white than in the ^. Terminal border^'with brighter j^ellow-brown edging. Muzo, Colombia, 4 — 800 m., $ 

 beUsar. discovered by'FASSL. — belisar Stich. Larger than the typical subspecies, of a darker ground-colour. Band 

 of the forewing somewhat broader, bright reddish brown; proximal boundary-line without distinct angulation, 

 arcuate, distal boundary as in the tj^ical subspecies. Hmdwing with a bright reddish ochre-yelloAV margmal 

 band 5 — 7 mm. in breadth at the distal margm, startmg m a point at the apex, soon developing into the 

 full band and remaming distinct nearly to the hinder angle, where it is lost in the ground-colour ua a vague 

 dusting; its proximal boundary is somewhat curved. Other\\'ise like the typical subspecies. Length of the fore- 

 wmg 54 mm. Bolivia (provuice of Yungas, La Paz).
