have hairy eyes, bristly palpi, and fore tibife hooked at the tip, differing in none of these respects from the tailless species, almost all of 

 which have hairy eyes and bristly palpi. Amongst the latter, L. Cassius, Argiohis, &c., have the fore tibias not hooked at the tip as it is 

 in L. Corydon, Alexis, Arion, &c. L. Alsus ditlers from all tlie rest in having tlie first branch of the postcostal vein confluent fur a short 

 distance with the costal vein, from which it again branches off to its ordinary length : the eyes are naked, the fore tibiie are not liooked, 

 and the four hind legs have very long prominent nngues, deeply notched at tlie base, witli large pseudunychia!, the outer division of 

 which is long and slender, and the inner one broader and shorter, and the pulvillus is heart-shaped; whilst L. (Pitliccoiis) llylax has 

 also naked eyes, scaly palpi, and spurlcss fore tibia>, but the wings have the veins arranged in the ordinary manner, and the ungues 

 and their appendages are as small and inconspicuous as in the rest of the genus. I liave been thus particular in examinin"- these 

 characters (several of which have never before been investigated by Lepidopterists), as I think they will afford more certain results in 

 grouping the species than the more general characters iiitherto resorted to. 



The existence of the short hair-like tail to the hind wings in some of the species, affords an easy means of dividing the species into 

 two groups (those without the tail forming, in fact. Dr. Horsfield's genus Polyommatus, and those with it being his Lycajna?), but, as 

 above shown, L. BaJtica approaches too nearly to the tailless " blues" to allow us to adopt a generic separation, at least until we learn 

 more of the transformations of the exotic tailed species. Again, if we adopt the separation of certain of the tailless species into a 

 separate subgenus Pithecops, we shall be under the necessity of restricting it to L. Hylax, and forming several other subgenera, with 

 L. Alsus, Cassius, Argiolus, Corydon, Alexis, Arion, &c., as their types. Mr. Swainson's views on tliis group are noticed under the 

 genus Lucia. 



With tliese views, I have considered it most advisable to retain the genus in its unrestricted state. The species are very numerous ; 

 unlike tlie Thecl«, however, their metropolis is in the Old World ; comparatively few and insignificant species beino- found in the 

 New World. The majority of the " blues," as the tailless species are called by collectors, are European ; whilst the tailed species are 

 more frequent in Asia and the Asiatic islands. About a dozen species, belonging to both groups, have been received from Australia. 



The Caterpillars of such species as have been observed feed upon leguminous herbs, such as Trifolium, Lotus, Onobrychis, Medicao-o, 

 &c. The Chrysalis is generally attached to the stem of the plant : but occasionally this state is passed beneath the surface of the earth.
