are of moderate size, and are, generally speaking, of uniform 

 colours. The fore-wings are sub-triangular and rather pointed, 

 with the sub-costal nervure four-branched ; the hind-wings are 

 oval, and rather produced towards the anal angle ; larva hairy, 

 and with four or six longitudinal rows of spines ; pupa with two 

 lateral spines " ( Wallace). 



This large genus includes several sections, which many 

 writers are inclined to treat as of generic rank. The following 

 species is the true type of the genus, 



APPIAS ZELMIRA. 



Papilio zeljiiira, Cramer, Pap. Exot. iv. pi. 320, figs. C-D (1780). 



This is an Indian Butterfly, measuring about two inches 

 across the wings. The male is white, with the nervures, 

 especially the branches of the sub-costal nervure, broadly black 

 towards the hind-margin, or expanding into black triangular 

 spots ; on the under side of the hind-wings nearly all the 

 nervures are black. The costa of the fore-wings is dusted with 

 bluish-grey, especially beneath, and the base of the costa of 

 the hind-wings is yellow beneath. The female is brown, with 

 sub-marginal white spots, and two large white spaces on the 

 fore-wings, and one on the hind-v/ings. On the under side, 

 the nervures are not black as in the male. Tlie fore-wings are 

 greenish in the cell and towards the tips, with a black streak 

 from the end of the cell meeting a black oblique sub apical 

 streak. On the hind-wings, the base of the costa is stained 

 with orange, the hind-margin is yellowish-green, and a yellowish- 

 green band runs from the sub-median nervure near the base to 

 the border, a little below the tip. 



The type of the genus Tachyris, Wallace, is T. iiero (Fab- 

 ricius), from the Malay Peninsula and the adjacent islands. 

 It measures about three inches across the wings, which are
