{Gen. D.L. , Plate LXXV., Fig. 7). In Thecla bosora , Hew., the upper side 
of the wing is dull blue, the fore-wing with broad brown anterior margin 
and borders, the brand very large and shining blue. 
Papilionidae. 
1. Pierinae. 
In the males of Leptalis the inner margin of the fore-wings and the 
costal margin of the hind-wings are not uncommonly produced, as in 
Euploea. In such species there is on the hind-wing above, and on the 
fore-wing beneath, a large shining area covered with very small, closely 
placed scales, and in the middle thereof an oval, dull chalk-white or ash- 
grey patch. When the wings are expanded, the patches of both wings lie 
directly one on the other. 
The male of most species of Callidrgas has near the base and the costal 
margin of the hind-wing a chalky patch (“ sac glanduleux,” Boisduval), 
the size, shape, and colour of which vary greatly with the species. Some¬ 
times it is covered by a mane of long hair springing from the cell. In 
other cases there is a patch opposite to it on the mider side of the fore¬ 
wings, between the median and submedian. This opposed patch and the 
mane appear each to exclude the other ; where I find the mane {argante, 
trite), the fore-wing patch is wanting ; where the latter is present ( philea , 
statira ), the mane is absent. 
Some species (as the Indian pomona ) bear hairs also on the inner 
margin of the fore-wing. Finally, in some cases {eubule) both hairs and 
brands are wanting, though the patch on the hind-wings may not be 
absolutely untraceable. 
In a few species of Nathalis , Gonepteryx and Golias, similar patches 
appear in the males. 
2. Papilioninae. 
The first of the divisions of the genus Papilio as recognized by Felder 
contains P. priamus , and the allied species of the now once again 
abandoned genus Ornithoptera. In the males of this division the inner 
margin of the hind-wings is much produced, and folded so that the upper 
surface lies within 1 ; the outer side of the folded margin is more diffusely 
scaled, and furnished along the submedian with a mane of brownish erect 
bristles; the basal half of the fold is again rolled inwards; the inner 
surface of the entire margin of the upper side of the wing is covered with 
black scales, without hairs. 
In the male of the second subdivision, which, like the first, is made 
up of species of the former genus Ornithoptera , the inner margin of the 
1 Dr. Karl Jordan informs me that the upper surface lies within only in papered 
specimens in which the margin has been pressed down. In nature the fold stands 
nearly upright, leaning towards the abdomen, and only its extreme base is again 
rolled inwards as described in the text.-—E.B.P.
