256 LLOYD'S NATURAL HISTORY. 



for T. urvillianus and T. crossus. T. lydius (Felder), which 

 inhabits Gilolo or Halmahera, an island not far from Batchian, 

 has the sub-costal band of the male of a very deep coppery- 

 red, but both in this species and in T. croesus, the only other 

 mark on the fore-wings, except a short dash at the base of the 

 inner-margin, is the very large oval blotch of scales. The hind- 

 wings are paler than the band of the fore-wings, and varied 

 with yellow. The female of T. cmsus does not differ much 

 from the ordinary females of this genus ; but that of T. lydius 

 is black, with the cell and two complete rows of long spots, 

 concave at the extremity, and the inner row very large, between 

 the nervures beyond the cell. The hind-wings are yellowish- 

 brown, with the base, nervures, a sub-marginal band of nearly 

 connected spots, and another on the hind-margin, black. 



GENUS ^THEOPTERA. 

 &theoptera, Rippon, Icones Ornith. p. 4 (1891). 



Fore-wings of the male very long, narrow, and pointed. 

 Hind-wings very long in both sexes ; in the male, with the fold 

 of the inner-margin enclosing scent-scales. Fore-wings with 

 the third sub-costal nervule rising from the end of the cell in 

 both sexes ; the fourth and fifth sub-costals separating at about 

 one-third of the distance from the cell to their extremity in the 

 male, and at a quarter of the distance in the female. 



^E. victoria (Gray), the type of this genus, is found in 

 Guadalcanar, one of the Solomon Islands. The male measures 

 six inches across the fore-wings, which are black, with the basal 

 third of the wings green and yellow, except on the costa ; and 

 another blotch of the same colour near the costa before the 

 apex, divided by the nervures. The hind-wings are green, 

 bordered ^utside by a yellow band, on which stand three 

 orange spots (also visible below, where they have black spots
