HESPERIA Cynisca.
GENERIC CHARACTER.--See Pl. 28.
SPECIFIC CHARACTER.
_Hesp. (Div. 2.) alis nigrescente-fuscis, subtus obscurioribus; anticis supra fascia flava trifissa (in feminis alba); posticis subtus immaculatis, castaneo-fuscis, margine exteriore flavo._
Hesp. (Div. 2.) Wings blackish-brown; anterior above with a three-cleft yellow band, which in the female is white; posterior beneath immaculate, chesnut-brown, margined externally with yellow.
The different s.e.xes of this insect will appear so strikingly dissimilar to those who are familiarised only with the nice distinctions that separate the species of European _Lepidoptera_, that this affinity by such may be doubted; nevertheless, observations in their native country, and the close examination of several specimens, will we are persuaded confirm the fact.
The male insect is distinguished (like all the _Hesperidae_) by having the eyes considerably larger, and the anterior wings more narrowed than in the other s.e.x: in this species the bands on their wings a.s.sume the form of three yellowish spots, adjoining which, on the inner side, is a semi-lunular villous mark, an almost constant indication (where it exists) of this s.e.x. The straw-coloured border beneath the posterior wings is narrower and darker than in the female; but in both it forms a slender marginal fringe on the upper surface. Legs deep rufous; antennae black; the club beneath and lunule round the eye straw-coloured.
Inhabits South Brazil, but is not common.
