HESTINA. 141 
" BoDV niodcniti'ly robust. 
" Head moderately lar^e, tut'tcd in front, hairy abnvo, usually markoil with white sp'its. 
" Eyes prominent, naked. 
" Haustellum yoUow. 
" Palj^i porroctod, divergent, the tips convergent. 
" Antenna' exactly half the length, or rather less than half the length, of tho fore wing, termi- 
nating in a distinct gradually-formed clul). 
" Ked- marked with small white spots. 
" Thokax moderately robust, very haii'y. 
"Fore wiitf/.f rather elongated, triangular. Costal margin moderately arched; outer margin 
slightly sinuate, emarginate, rather shorter than the inner margin ; inner margin straight. 
First subcostal nervule in tho typical species given off from the costal ncrvurc some little 
distance before the apex of the cell ; second just before the apex ; third much nearer the 
origin of tho fourth than to tho apex of the cell, extending to the apex of the wing. In 
II. jtersiiniUs and its allies the first subcostal is given off a short distance before the end of 
the cell, the second at a considerable distance beyond, the third and fourth at about equal 
distances apart beyond the second. Upper discocellular nervule very small, outwardly 
oblique ; middle about twice as long as the upper, inwardly oblique, forming the base of 
the lower discoidal nervule ; lower entirely absent, thus leaving the discoidal cell open. 
Third median nervule moderately curved. Submedian nervure straight. 
" Hind ivbu/s with the costal margin much arched at base, thence nearly straight, outer margin 
in the typical species forming an angle at the end of the second subcostal nervule, above 
and below which it is nearly straight, but sinuous ; abdominal margin slightly excavated 
at the anal angle. I'ra'costal nervure simple, strongly bent outwards at the tip. Second 
subcostal and discoidal nervules given off from the costal very close together in the typical 
species, tho latter sinuous. In H. persimilis they are given off much further apart, and the 
discoidal nervule is straight. 
" Abdomen slender, somewhat long." (de Niceville, J. c.) 
The typical species is the Chinese II. assimilis. " The genus is very 
closely allied to Euripus, and like Nejitis, Argynnis, and Cyrestis, it com- 
prises two groups, in which the position of the second subcostal nervule of 
the fore wing ditfers : in //. nama, which most nearly resembles the typical 
species, that nervule is given off before the end of the cell, in the other 
Indian species it is emitted far beyond the cell. These latter, which in this 
featiu-e coiTcspond witlt EHripus, and also more closely resemble it in colour 
and markings, are distinguished from Eurqjus by the more regular and less 
sinuate outline of the wings, the rounded, not linear, shape of the pale discal 
markings, and the colour of the haustellum." {de NiceviUe, J. c.)
