terminated by a thickened compressed club abruptly inflected or bent 

 outwards: the feet are slender, perfect, and alike in both sexes. 



In the Chilognathiform or Juliform stirps, the principal of the whole 

 tribe, the larva is long, and cylindrical : attenuated at both ends and 

 transversely striated, as m, that of Colias, at the confines of the vermiform 

 stirps; distended about the fourth or fifth segment of the body, and 

 tapering gradually towards the tail, and more abruptly to the head, in the 

 typical group, the true Papiliones; acquiring tubercles, which, in the 

 more remote genera, increase in length, and show the transition, through 

 Euplcea, and Heliconia to the Chilopodiform stirps which succeeds; the 

 head is attached to the body by a very small articulation, and appeal's 

 when exserted, separated from it; behind it is a bifid fleshy organ, 

 or furcula. The pupa is attached as in the preceding stirps ; it is naked 

 and angulated, terminated, in the typical forms, at the upper extremity 

 by two processes, in those near the vermiform group by one short process 

 alcme. The imago is the perfection of the whole order; an assertion 

 which will readily be credited when it is recollected that this stirps com- 

 prehends the Papiliones Equites and Danai of Linnaeus, and that his 

 Heliconii stand at the immediate confines in the succeeding group ; the 

 palpi in the typical species are shorter than the head, their third joint is 

 very minute, and they are concealed by a very dense covering of long 

 bristly hairs ; the antennae are marked with defined rings at the numerous 

 joints, are elongate, filiform at the base, and terminated in the typical 

 group by a cylindrical club attenuated at both ends ; the feet are gener- 

 ally long and robust, and the whole of them are perfect and fitted for 

 walking. 



In the typical larva of the Chilopodiform or Scolopendriform stirps, 

 the appendages noticed as simple and fleshy on the body of that of 

 Euplcea and Heliconia become rigid and armed with transverse spines. 

 The pupa is naked and angulated, and is generally suspended by the tail 

 with the head directed downwards. The palpi of the perfect insect pro- 

 ject beyond the head, the third joint distinctly appearing and being closely 

 covered with down : the antennae are of moderate length with an abrupt 

 club at the apex which is broad and compressed in the typical species : 

 the anterior are spurious and imperfect and appHed to the under surface 

 of the thorax ; Vanessa is typical of this stirps, which passes off into the
