54 LLOYD'S NATURAL HISTORY. 



and the fringes are white. The hind-margins are scalloped, 

 each projection being intersected by a nervule, that at the ex- 

 tremity of the upper median nervule forming a short broad tail. 

 The green bands differ in width and colour, according to the 

 species, and are sometimes tinged with coppery, or even pink, 

 but they never exhibit the bright green colour seen in the 

 species of Cydimon. A species of this genus has been seen 

 sporting in large numbers round Pandanus trees in North 

 Australia, but its transformations are still unknown. 



The genus Nyctalemon^ Dalman, contains larger and duller 

 coloured species, with long hind-wings, produced into a curved 

 tail at the end of the lower sub-costal nervule, and a very long, 

 spatulate tail at the end of the first median nervule, the middle 

 nervule running into the broader lobe which forms the basal 

 half of this tail. The wings expand five or six inches, and 

 are of a brown colour, traversed by a white band of variable 

 width, and with the hind margin and tails of the hind-wings 

 more or less bordered with white. The species are very simi- 

 lar, and some authors regard most of them as forms of one 

 species, N. patrodus (Linn.). 



The larva is described by Dr. Kiihn as yellowish-white, with 

 black, symmetrical, but not very constant, markings. The 

 segments five, six, and ten are always very dark. Head and 

 legs reddish-brown. The whole body is covered with black 

 warts, each bearing a short bristle. Some larvae are greenish- 

 white, with faint greenish markings. The pupa is enclosed in 

 leaves spun together on the ground. The larvae spin threads 

 while walking, from which they sometimes suspend themselves. 

 The pupa is dark reddish-brown, with a yellowish-brown space 

 round the first three stigmata. The pupa-state lasts about four- 

 teen days, and the Moths appear at night, from 1 1 p.m. to 

 i a.m. The larva feeds on a shrub common in mangrove 

 swamps, which has a bluish-green bark, while the young leaves
