LEPIDOPTERA. 607 



Pavonia, God., has the central cell of the hind wing;s 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 Amathtisia, Fabr. 

 The following- have the discoidal cell of the hind wings closed behind. 



Brassolis, Fab., has the antenna 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 antennse at a short distance from the base, gradually thickening, 

 and forming an elongated mass. 

 Euryhia, lUig., has short palpi, but they are thicker, and the club of the antennae is fusiform and bent. 



Satynis, 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, ^geria, &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 

 Fig. i28.-sa,yru8 (Hipparchia) pa,npiMiu,. ^^^j^^ ^^^^ ^^^ preceding; thc 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 

 them in his Papiliones plebeii, and division Rurales. They are the G. Argus of Lamarck, and Fabricius 

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



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- 

 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.] 



Polyommatus, 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 antennae of a completely isolated form. 



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 known to be real. Latreille here added the genus 

 2ep*3/rj««, 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.] 



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

 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 

 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 

 urbicolcB 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 different Lepidoptera conduct us very well to the second family. They compose two sub- 

 genera. 



Hesperia, Fab., — 

 Which have the antennae distinctly terminated by a club, and the palpi short, broad, and very squamuse 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. Malvie, Fab., is a common species. Its caterpillar is elongated, with the first 

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



Urania, Fab., — 

 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 

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

 affinities of these interesting insects, in the new edition of Drury's Exotic Entomoloffy.]
