MORrHIDiE DRTJSILLA AND HYANTIS. 



HYANTIS. Hewitson. 



Body small, quadrate, abdomen slender. Eyes small, smooth. Palpi rather long, com- 

 pressed, clothed with scales throughout, encircling the eyes. Antennae rather short, thickened 

 gradually to the point, the articulations numerous and easily seen. 



Anterior wing rather large : the costal margin arched, apex rounded, outer margin slightly 

 sinuated at the middle, inner margin rounded, protruded as in Euploea ; costal nervure swollen 

 at its base, reaching beyond the middle of the wing : subcostal nervure with four branches : two 

 together just before the end of the discoidal cell, the third midway between the cud of the cell 

 and the apex of the wing, the fourth at one-third of the distance between the last and the apex ; 

 discoidal cell nearly half the length of the wing, closed : upper disco-cellular nervure very short, 

 the second semi-circular arched inwards rather short, the third more than twice the length of 

 the second curved united to the third branch of the median nervure at a distance from its 

 base. 



Posterior wing oblong, circular, with large abdominal fold ; costal nervure joining the margin 

 considerably beyond the middle : subcostal nervure with its first branch arising near the base 

 of the wing: the discoidal cell short and nari-ow, closed ; the upper disco-cellular nervure long, 

 arising at a short distance below the first branch of the subcostal nervure, at first in a transverse 

 direction, and afterwards passing longitudinally down the wing: the second half its length, 

 joining the third median nervure a little beyond its base. 



Fore legs of both sexes short, tibia3 and tarsi of both so densely clothed with hair as 

 to conceal the joints of the tarsi. 



Hind legs long, slender, smooth : the femora tibiae and tarsi of equal length. 



HYANTIS HODEVA. 5, 6. 



Upperside. Male, white ; both wings with the costal margin and apex broadly brown, the 

 outer margin also brown to beyond its middle ; anterior wing rounded and produced at its 

 inner margin as in Euploea : near this margin a large oval pale rufous spot : near the apex a 

 small spot of white and a black ocellus with some minute white dots. Posterior wing, with a 

 small black ocellus with white pupil, broadly bordered with yellow, and marked by a very 

 indistinct circle round the ocellus. 



Underside as above, except that the ocellus at the apex of the anterior wing has the pupil 

 and some smaller dots of white and an iris of yellow : that the ocellus of the posterior wing 

 is larger and has several minute dots of white and the iris bordered with brown : that there 

 is a similar ocellus on the costal margin bipupillated and dotted with white. 



Female larger : the wings broader, suffused with darker brown, the nervures dark brown ; 

 anterior wing with the centre alone white ; posterior wing white only to the middle, tinted with 

 orange-yellow towards the inner margin : the ocellus small, indistinctly pujjilled with white ; the 

 iris orange-yellow, bordered with brown and encircled above by a pale hue ; underside it difiers 

 only in the broader outer margin of the posterior wing.

This is a species of singular interest, from the remarkable resemblance it bears to the Drusillas, differing at 

 the same time from them widely in the arrangement of the branches from the subcostal nervure of the anterior 

 wing, in the form of that wing with its projected inner margin, and in the closed discoidal cell of tl\e posterior 

 wing. It is unique in the collection of Mr. Wallace.
