358 MODERN CLASSIFICATION OF INSECTS. 
respects from the family Nymphalidae, in which it is arranged by 
Stephens, with the remark, however, of its varying therefrom. It is 
true that the general appearance, colours, and markings of the butterfly 
seem to indicate a relation with Melitaa; but the imperfect structure 
of the fore legs in the male, whilst they resemble the others in the 
female, the minute simple ungues, the posterior tibize destitute of 
spurs, the onisciform larva (fig. 99. 12.), and the girt chrysalis 
(fig. 99.18.), are characters indicating a much closer relation to some 
of the Erycine. 
One of the most curious species in the family is the Barbicornis 
Basilis God. (fig. 101. 5.; 6. head and antenna; 7. palpus; 8. foreleg), 
an inhabitant of Brazil, and remarkable for the anomalous structure of 
its antenne ; the veins of its wings agree, however, with those of most 
of the Erycine, as figured by Boisduval. 
The fifth family, Lycanipm Leach, Polyommatide Swainson, or 
the Vermiform Stirps of Dr. Horsfield (jig. 100. 8. Thecla Quercus ) 
comprises a numerous assemblage of small and weak, but beautiful 
butterflies, distinguished by the minute size of the tarsal claws, the 
apparent* identity in the fore tarsi of both sexes, the fore legs being 
fitted for walking ; the last joint of the palpi is small and naked (jig. 
100. 6. head of Polyommatus ; 7. ditto of Myrina); the anal edge of 
the hind wings slightly embraces the abdomen; the discoidal cell 
of the hind wings is apparently closed by a slender nerve. The 
caterpillars have a great resemblance to woodlice (fig. 100. 9. larva 
of Thecla Quercus; the points beneath indicate the situation of 
the head and feet ; and fig. 100. 10. represents the three terminal seg- 
ments seen beneath, which are soldered together on the upper side), 
and the chrysalis is short, obtuse at each end, and girt round the 
middle as well as attached by the tail (fig. 100. 11.). Several dis- 
tinct groups exist in this family, namely, the Blues, Polyommati; the 
Coppers, Lycenz ; and the hair-streak Butterflies, Thecle. Some 
* The tarsi of both sexes have been described by Horsfield, Curtis, &c¢., as 
identical ; but, in examining Thecla Isocrates, I discovered that the tarsi of the 
males consist of a long, simple joint (fig. 100. 12. ¢, 13. 9 fore leg), and I subse- 
quently found the same to be the case in the Polyommati ( fig.16. ¢, 15. 9 fore tarsus 
of Pol. Corydon), Fig. 100. 14. is the middle leg of Thecla, alike in both sexes, ex- 
hibiting the femoral spur and tibial notch.
