LEPIDOPTERA. 



C07 



Pavonia, God., has the central cell of the hind wings closed, and the innermost nerve of the fore wiiig-s curved 

 like an S. One of the species, P. Pkidippm; from the East Indies, with the hind vvin;;s tailed, is the type of the 

 fi-cnus Amaihuaia, Fabr. 

 The following: have the discoidal cell of the hind win^^s closed behind. 



Brasso/is, Fab., has the antennje suddenly clubbed, and the palpi short; the males have a loni^ntudinal slit at 

 the inner edfje of tlie hind wings, covered with hair. 



Eumeiiia, God., with the jialpi longer, and the antenna; at a short distance from the base, gradually thickening, 

 and forming an elongated mass. 

 Euryhia, Illig., has short palpi, but they are thicker, and the club of the antenna: is fusiform and bent. 



^atijrus, Latr. {Hipparchla, 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 thi'ee 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 

 ■SG """^^'^^'teO'NiP^^s^ -^'W' J^/ British genus, the majority of which are ornamented with eye. 



like spots. Such are Pap. Calatheay Janira, .Ef/eria, &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 

 FifT- i2s._satyn.MHipparchia) pampi,iiu.s. ^^^^j^^ ^^^^^ ^^^ prcccdlng ; thc tarsal claws are very 



minute. The caterpillars are oval, or like AVuod-lice. The chrysalides are short, entire, and alwavs 

 attached by a thread round the middle of the body, hke those of Papilio or Pieris. Linnious united 

 them in his Papil/ones pledeii, and division Rurales. They are the G. Argus of Lamarck, and Fabriciiis 

 has divided them into many genera, which have need of revision. 



Some of these have the antenniT terminated by a knob. 



Eriicina, Latr., has the fore feet, at least in the males, much shorter than the others. [These are almost exclu- 

 sively South American Butterflies.] 



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.] 



Pobiommatus, Latr., thus named from the numerous eye-like spots on the wings, has the palpi not much extending 

 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 antenna? of a completely isolated form. 



Barbicornisy God., has the antenns in both sexes setaceous and plumose. [Established upon a Brazilian species, 

 which Latreille considered fictitious, but which is now well known to be real. Latreilie here added the genus 

 Zcjihjjrins, Dalman, which he described as having the antennte terminated by ten or twelve globular joints ; the 

 germs is, however, identical with Polyommatus. See Boisduval, Hist. Nat. Lep, i. p. 114.] 



The second section of the Diurnal Lepidoptera is composed of species in which the posterior tibire 

 liave 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 wliich, however, but a few are known, roll 

 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 Plehni 

 urhicohe of Linnaeus, and were united with the Polyommati under the name of Hesperia, by Fabricius. 

 But we must further add some exotic Lepidoptera, whose natural station has not yet been discovered. 

 These ditferent Lepidoptera conduct us very well to the second family. They compose two sub- 

 genera. 



Hesperia, Fab.,— 

 Which have the antenna distinctly terminated by a club, and the pnlpi short, broad, and very squamuse in front. 

 [The species are very numerous, of small size, and are known to cohectors under the name of Skipper Butterflies, 

 from their peculiar flight.] H. Malvce, Fab., is a common species. Its caterpillar is elongated, with the lirst 

 segment behind the head narrowed, a character familiar to this group. 



Urania, Fab., — 

 Has the antennEe 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. RMpheus, Leilns, Lavinia, 

 Oronten, &c. They form Dalman's genera Ci/dimon, Nijctalenion, and Sematura. [See the memoir of Mac Leay 

 on the transformations of a species which inhabits Cuba, in the Trans. Zool. Soc, and my observations on the 

 adinities of these interesting insects, in the new edition of Drury's E^rotic Entomology.']
