418 MR. J. H. LEECH ON THE BUTTERFLIES [May 3, 



down its centre with paler scales ; beyond this patch is a circular 

 black spot ; a black double spot occurs in the cell, beyond which are 

 two large black patches touching the costa ; margins of all the 

 wings black ; an irregular black submarginal band runs round all 

 the wings, dividing near the anal angle and enclosing two circular 

 spots of the ground-colour ; veins deeply marked with black, 

 especially near the outer margins. Underside — markings of the fore 

 wing reproduced, with the addition of a white costal mark, and six 

 white spots about the apex : hind wing — all the veins broadly marked 

 with black ; the ground-colour replaced over a great part of the 

 surface by dirty white. Underside of the abdomen white. 



Allied to Castalia (nom. prseocc, Moore) dichroa, Koll., and 

 chandra, Moore, both Himalayan species. 



I managed after much difficulty lo secure a single male, which was 

 flying strongly about some oak trees at Chang-Do, south of Grensan, 

 Corea, beginning of July, 



68. EuRiPUS coREANus, nov. sp. (Plate XXXVI. fig. 1, S ? •) 



Expanse, S 4^, 2 5 inches. 



Wings of male dark brown, the basal half suffused with purple ; 



a straight white streak, originating at the base of fore wing, traverses 



about ^ of its width ; a submarginal row of spots runs round all the 



wings, terminating at the anal angle in a bright carmine elongated 



spot ; the discal area of both wings is traversed by two series of 



spots arranged irregularly, but concavely to the base of the wings, 



besides which there are two (sometimes three) spots near the apex 



of the fore wing and near the anal angle of the hind wing, situated 



inside the submarginal baud. The two discoidal spots are often 



confluent. All spots situated on the purple colouring are pure 



white, those on the remainder of the wings pale yellow. Wings of 



the female dark brown, spotted as the male ; all the spots about the 



costa and disk of both wings white, the remainder pale yellow ; anal 



lunule carmine. Underside of both sexes — fore wings black ; costa, 



apex, and outer margin pale bluish green, all markings of the upper 



surface reproduced ; hind wings pale bluish green ; veins very 



prominent, markings of the upper surface reproduced, mostly 



bordered with black ; anal lunule carmine. 



The underside of this species is sufficiently distinct to prevent any 

 possible confusion with Euripus charonda. I took a large series of 

 both the species (one in Japan, the other in Corea) and they seem 

 to be quite constant. 



This insect occurs commonly in a large forest about 15 miles 

 south of Gensan in July ; it frequents the tops of trees, and is very 

 difficult to take in good condition on account of its powerful flight. 



69. Euripus charonda. 



Euripus cliaronda. Hew. Ex. Butt. iii. t. 4. fig. 1 (1863). 



This large species is common about Yokohama, Lake Biwa, and 

 the province of Kaga ; it flies very high, only occasionally descending, 

 like Apatura.
