vicole, and Fabricius—Entom. Syst.—in a homonymous section of 
his Hesperi@. They form the genus Argus of M.de Lamarck. Fa- 
bricius ultimately—Syst. Gloss.—divided it into several genera, the 
characters of which demand revision. 
Sometimes the antennze terminate, as usual, in a solid globuliform, 
or clavate inflation. 
In some, or at least their males, the two anterior legs are much 
shorter than the others. They compose the subgenus 
Erycina, Lat., 
And are peculiar to America *. 
In the others all the legs are alike in both sexes. 
Myrina, Fab. 
The Myrinz are distinguished from the following subgenera by 
the remarkable elongation and projection of their inferior palpi f. 
Those species in which these organs do not extend considerably 
beyond the clypeus, form the subgenus 
PoLyOMMATUS, 
So called because the wings of most of them are marked with small 
ocellated spots. 
Several species have been collectively designated by the name of 
Petits porte-queuwe. The most common in the environs of Paris is the 
P. Alexis; Papilio Alexis, Hiibn., LX, 292—294; Argus 
bleu, Geoff.; Godart, Hist. Nat. des Lépid., &c., 1, ii, sect. 3. 
Superior surface of the wings of the male azure blue, changing 
to a delicate violet, with a small black streak along the pos- 
terior margin, and a very white fringe; that of the female 
brown, with a range of fulvous spots near the posterior margin, 
and a black line on the middle of the superior ones. The in- 
ferior surface of the wings is nearly the same in the two sexes; 
it is grey, with a range of fulvous spots enclosed between two 
lines of black points and streaks near the posterior margin; we 
may also observe some black points margined with white. 
Its caterpillar lives on the Onobrychys, Broom, &c. Its 
colours are various f. 
Other Lepidoptera of the same division present antenne of a truly 
insulated form. Those of one of the sexes of the BarBicornis, Go- 
dart, are setaceous and plumous§. Those of the Zepuyrius, Dalm., 
are terminated by ten or twelve globular joints separated like the 
beads of a rosary |]. 
* Encyc. Méthod., article Papillon, genus Erycine. 
+ Ibid. Fabricius has established several other genera in this division, which I 
have not yet sufficiently examined. Certain species from South America resemble 
Pyrales in their superior wings, which are arcuated exteriorly at base. The club 
of the antenne also presents various modifications which may serve as a ground of 
division; but we should have a great number of species, and be particularly well 
acquainted with their metamorphoses,
