EUPLCEINJE. 23 



of biconical spots terminating outwardly in a dilated streak at end of each vein, 

 between wliicli is a marginal series of conical spots. Body and legs black ; head and 

 thorax spotted with white ; thorax above, palpi in front, and femora beneath streaked 

 with white ; abdomen black above, white beneath. 



Expanse, 4f to 5f inches. 



Larva. — Unknown. 



Habitat. — Ceylon. 



A discriminating character between this species and its nearest ally, K. Malabarlca, 

 is in the form of the lower discal spots on the forewing — which in H. Jasonia are 

 always quadrangular, and in the other, cordate ; and also in the zigzag streak 

 crossing the end of the cell having its lower outer angle always sharply extended 

 between the radial and upper median veinlet. 



Haunts and Habits. — According to Sir Emerson Tennent (Nat. Hist, of Ceylon, 

 i. 426) " this butterfly is called by Europeans in Ceylon by the various names of 

 Floater, Spectre, and Silver-paper-fly, as indicative of its graceful flight. It is found 

 only in the deep shade of the damp forest, usually frequenting the vicinity of pools 

 of water and cascades, about which it sails heedless of the spray, the moisture of 

 which may even be beneficial in preserving the elasticity of its thin and delicate 

 wings, that bend and undulate in the act of flight." Dr. Thwaites states that it 

 " affects the glades of woods, and is notable for its graceful flight, rising and 

 descending almost like a gossamer in the air, and well deserving the name of the 

 Sylph, which is commonly given to it." Another correspondent, Capt. E. J. 

 Hutchison, writes that " In the forests and especially about waterfalls in the 

 "Western, Central, and Southern Provinces, this butterfly may be found all the year. 

 It has a very slow floating flight, often poising nearly motionless, and is easily caught." 

 Specimens of both the pale and dark tinted examples of H. Jasonia, collected by 

 Mr. E. E. Green in 1884, each bear the month of April as the date of their capture.

 Imago. — Wings semi-transparent ; greyish-white, the female somewhat fuliginous- 

 white; veins and markings black. Forewing with the costal base broadly black, 

 merging into a large spot within the cell ; the traversing cell lines broad, and 

 present only from the base to the spot, their continuation from the outer edge of 

 the spot to the end of the cell (as in other species of the genus) being entirely 

 absent in both sexes ; a medial costal spot and an irregular streak across end of the 

 cell ; an inverted conical inner discal spot, an elongated clavate mark below the 

 median vein and a streak along middle of the posterior margin, a discal series of
