454 MR. L. DE NicfiviLLE ON NEW OR [May 3, 



ochreous colour extending; along the first median nervule for a short 

 distance ; cilia black. Hind wing with the outer margin somewhat 

 broadly ochreous, sprinkled with dark-brown or blackish irrorations ; 

 cilia black, tipped with white on the three upper indentations 

 between the veins. Underside : both wings very variegated, the 

 ground-colour apparently being ochreous, thickly irrorated with 

 dark-brown striae ; a discal obscure purplisli fascia, inwardly bounded 

 by a dark line. Fore wing with three short subcostal bands reaching 

 the middle of the cell, and a broader subapical one, ochreous (these 

 fasciae are formed by those portions of the ground being free from 

 irrorations), an obscure purplish patch at the apex, an irregular 

 series of five round violet-white spots placed between the veins mid- 

 way between the cell and the outer margin, the two in the median 

 interspaces large, the other three very small. Hind wing with the 

 inner edge of the black discal line marked with an ochreous bar at 

 the costa, the outer margin showing more of the ochreous ground- 

 colour than the rest of the wing ; five discal viulet-white spots 

 between the veins, the three lower ones large, the two upper small, 

 the lower ones surrounded by a black ring, the spot in the first 

 median interspace the largest of all. — Female. Upperside : fore 

 wing with the subapical band broader, richer-coloured, and extending 

 along the costa ; the black apical patch crossed by yellow veins ; the 

 median nervules also marked with yellow near the band. Hind wing 

 with the outer margin richer ochreous. Underside much paler ; 

 the darker irrorations far less dense ; no trace of the diffused pur- 

 plish fasciae. 



I have placed this species somewhat doubtfully in the genus 

 Cyllogenes, the chief recorded structural character of which is the 

 presence of a large deep black patch in the male, this " sexual 

 mark " being entirely absent in my species, the sexes being prac- 

 tically marked alike. C. janetce is, however, much more closely 

 allied to C suradeva, Moore (hitherto the type and only species in 

 the genus), than to any other described species, the yellow band on 

 the fore wing and the upperside being a striking feature, which is 

 common to both species. On the underside the blind ocellated spots 

 are precisely similar in both species ; and the purplish fasciae on the 

 underside of the male of C. janetce is of the same tint as obtains on 

 the upperside of both sexes of C. suradeva. The truncation of the 

 apex of the fore wing in both sexes of C. janetcB (more especially in 

 the male) is a good structural character by which to separate the 

 two species in both sexes. It agrees also structurally with Cyllogenes 

 suradeva in the almost similar extraordinary character which obtains 

 also in the genus Parantirrhcea of Wood-Mason, and which for 

 Cyllogenes has not hitherto been noticed, viz. : in the male the three 

 median nervules of the fore wing are considerably further apart at 

 their apices than in the female, owing to the fact that the lower one 

 has to supply the place normally taken by the submedian nervure, 

 as it reaches the outer margin but a very short distance anterior to 

 the anal angle ; while the submedian nervure is very short, slightly 

 sinuous, and reaches the inner margin at considerably less than half
