LEPIDOPTERA. 
607 
Pavonia, God., has the central cell of the hind wings closed, and the innermost nerve of the fore wings curved 
like an S. One of the species, P. Phidippus, from the East Indies, with the hind wings tailed, is the type of the 
genus Amathusia, Fabr. 
The following have the discoidal cell of the hind wings closed behind. 
Brassolis, Fab., has the antennae suddenly clubbed, and the palpi short; the males have a longitudinal slit at 
the inner edge of the hind wings, covered with hair. 
Eumenia, God., with the palpi longer, and the antennae at a short distance from the base, gradually thickening, 
and forming an elongated mass. 
Eurybia, Illig., has short palpi, but they are thicker, and the club of the antennae is fusiform and bent. 
Satyrus, Latr. [Hipparchia, Fabr., and of English authors], 
has the palpi extending beyond the clypeus, very compressed, 
the antennae terminated by a small club, or by a slender elong- 
ated mass ; the two or three basal nerves of the fore-wings are 
swollen. The caterpillars are naked, or nearly smooth, with 
the extremity of the body forked. The chrysalides are bifid in 
front, and the back is tubercled. [This is a very numerous 
British genus, the majority of which are ornamented with eye- 
like spots. Such are Pap. Galathea, Janira, uElgeria, &c.] 
We terminate this first section of the diurnal Lepi- 
doptera by those which have the palpi 3-jointed, but the 
third joint is nearly naked, and much less clothed with 
scales than the preceding ; the tarsal claws are very 
minute. The caterpillars are oval, or like Wood-lice. The chrysalides are short, entire, and always 
attached by a thread round the middle of the body, like those of Papilio or Pieris. Linnaeus united 
I them in his Papiliones plebeii, and division Purdies. They are the G. Argus of Lamarck, and Fabricius 
I has divided them into many genera, which have need of revision, 
j Some of these have the antennae terminated by a knob. 
Erycina, Latr., has the fore feet, at least in the males, much shorter than the others. [These are almost exclu- 
i' sively South American Butterflies.] 
I: In the others the fore-legs are like the others in both sexes. 
' Myrina, Fab., is distinguished by the great length of the palpi. [Exotic species.] 
j Polyommatus, Latr., thus named from the numerous eye-like spots on the wings, has the palpi not much extending 
I beyond the clypeus. [The species are numerous, of small size, and are known under the names of Blues or 
Coppers.] The most abundant species of the former is Pol. Alexis, the Common Blue. 
Other Lepidoptera of this division are furnished with antennae of a completely isolated form. 
I Barbicornis, God., has the antennae in both sexes setaceous and plumose. [Established upon a Brazilian species, 
!| which Latreille considered fictitious, but which is now well knowm to be real. Latreille here added the genus 
Zephyrius, Dalman, which he described as having the antennae terminated by ten or twelve globular joints ; the 
genus is, however, identical with Polyommatus. See Boisduval, Hist. Nat. Lep. i. p. 114.] 
|i The second section of the Diurnal Lepidoptera is composed of species in which the posterior tibiae 
have two pairs of spurs, one pair at the tip and another above, as in the two following families : 
the lower wings are generally placed horizontally in repose, and the extremity of the antennae is 
often suddenly bent and pointed. Their caterpillars, of which, however, but a few are known, roll 
i up leaves, in which they spin a thin web of silk, within which they are transformed to chrysalides, 
- which have smooth bodies, and are without angular eminences. They form the division of the Plebeii 
urbicolce of Linnaeus, and were united with the Polyommati under the name of Hesperia, by Fabrieius. 
:| But we must further add some exotic Lepidoptera, whose natural station has not yet been discovered. 
I' These different Lepidoptera conduct us very well to the second family. They compose two sub- 
!' genera. 
I Hesperia, Fab.,— 
Which have the antenna; distinctly terminated by a club, and the palpi short, broad, and very squamose in front. 
[The species are very numerous, of small size, and are known to collectors under the name of Skipper Butterflies, 
from their peculiar flight.] H. ilfatocP, Fab., is a common species. Its caterpillar is elongated, with the first 
i segment behind the head narrowed, a character familiar to this group. 
;j Urania, Fab., — 
I Has the antennae filiform at the base, and gradually slender and setaceous at the tips, and the palpi long, slender, 
with the second joint very compressed, and the last long, slender, and naked. Pap. Rhipheus, Leilus, Lavinia, 
Orontes, &c. They form Dalman’s genera Cydimon, Nyctalemon, and Sematura. [See the memoir of Mac Leay 
ij on the transformations of a species which inhabits Cuba, in the Trans. Zool. Soe., and my observations on the 
affinities of these interesting insects, in the new edition of Drury’s Exotic Entomology.']
