 spot of the hindwing seems to be the Peruvian form of it. Tiie V <•* helin-t is by far larger than the .j", with 

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

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

 ring outside of Ciuiana. in Venezuela and Brazil. Here the i-ostal area of the male hindwings is nn'niate. and 

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

 golden-yellow or golden-red {miniacea St/'r/i.) and nnuh less variable oblique band of the forewing. The spe- 

 cies is rare.

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

 there seems to be hardly an_\ difference from the preceding.

 radiate spots; iieneath the wings are almost exactly like ihose of the other Xenanrlrn, dull golden-green, with 

 black veins. The 2 may be coloured like the r^*, but larger and with broader wings, but it may also occur with- 

 out distinct marginal rays and \\ ith a whitish or variegated oblicjue 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-ycllo\^- or red. Rare. 



X. piilclierrima H.-Schdff. (12.Sa) fits badly into this genus, but neither to Lymnas nor. according /)"'Wif(v;//(r(. 

 to Stichkls examinations, to Themone nor in any way to Eurygona {Euselasin). Hindwings as in prasinata, 

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

 blue-tinged spots. There is a most conspicuous l)road yellow median liand on the under surface. Suiinam. 

 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 Bnrhirornis correspond to homochrome foims of Lymnns, 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.
