 spot of the hindwuig seems to be the Peruvian form of it. The $ of helius is by far larger than the ,^, with 

 particularly long forewings exhibiting an obsolete oblique band varying in size, shape and colour. If vve would 

 denominate all these differences of the band, we could give just as many names as there are specimens, for

 ring outside of Guiana, in Venezuela and Brazil. Here the costal area of the male hindwings is miniate, and 

 this colour extends as far as to the base of the wing. The 9 of it is scarcely larger than the (J with a bright 

 golden-yellow or golden-red (minicicea Stick.) and much less variable oblique band of the forewing. The spe- 

 cies is rare. 



X. vulcanalis Stick, is unknown to me; it is said to be black above with a large, nearly oviform, vulcanalis. 

 bright red spot on the hindwing, the tip of which touches the base of the hindwing; from Rio San Juan 

 in Colombia. Length of forewings of the ^ 16 mm. Except the red spot of the hindwing touching the base, 

 there seems to be hardly anj' difference from the preceding. 



X. nigrivenata Scks. from Costa Rica has the grejish-green shining spaces between the veins as nigrhenata. 

 prasinata (131 i) shows them, but besides a large, orange-red costal spot of the hindwings extending from near 

 the base almost to the margin and to the median. From Juan Vinas.

 radiate spots ; beneath the wings are almost exactly like those of the other Xenandra, dull golden-green, with 

 black veins. The $ may be coloured like the ^, but larger and with broader wings, but it may also occur with- 

 out distinct marginal rays and with a whitish or variegated oblique band on the forewing. These different 

 forms fly simultaneously at the same localities. Their affinity is easily recognized by the abdomen being be- 

 neath in the middle of a bright reddish-yellow or red. Rare. 



X. pulcherrinia H.-Sck'dff. (128 a) fits badly into this genus, but neither to Lymnas nor, according pi'^cAerriwo. 

 to Stichels examinations, to Tkemone nor in any way to Eurygona (Euselasia). Hindwings as in prasinata, 

 but the blue radiate spots somewhat removed from the margin ; forewing with a chain of white, po.steriorly 

 blue-tinged spots. There is a most conspicuous broad yellow median band on the under surface. Surinam. 

 Unknown to me in nature; apparently very rare.

Easily recognizable by the very small hindwings provided with a long apex of the tail on the lower 

 radial (uppermost median). All the species of Barbicornis correspond to homochrome forms of Lyjiinas, as 

 has already been said in the Preface (p. 620). Most of the species are rare, exhibiting characteristic differen- 

 ces at every habitat and having about the same habits as the Lymnas.

 oblique spot before the apex of the forewing. This oblique spot has a different appearance at everj' habitat. 

 — in specimens from Espiritu Santo it has such a cuneiform shape that the thick end of the wedge lies at 

 the distal margin, the tip ol it at the costa (= cuneifera ab. nov.) (132 a). — In typical melanops from South cuneifera. 

 Brazil and Paraguay the band is uniform, at the costa even a little broader than at the distal margin. — In

 very much smaller than Brazilian specimens. — ephippium Tkieme (132 a) has the most extensive oblique epJupph(»>. 

 spot; at the costa it is so widened that it occupies its whole median third; here also the veins are more 

 prominently light. — aterrama fot-m. nov. (132 a) is entirely black, with indistinctly light veins; it might, aterruna. 

 therefore, be taken to be an acroleuca having lost the white apical margin; but the shorter, more straight 

 tail of the hindwing characterizes it as a melanops in which the oblique hand of the forewing is absent; 

 from South Brazil and Paraguay.

 melanops. The typical flibapkina is only as large as the figured basilis. At some habitats, however, the animals
