ON NEW AND LITTLE-KNOWN BUTTERFLIES. 275 



12. CYANIRIS MUSINA, Snellen, PI. 0, Fig. 19, $. 



Lyccena musina, Snellen, Tijd. voor Ent., vol. xxxv, p. 145, n. 8 (1892); Cyaniris jynteana, 

 var., Distant {nee de Nice'viHe), Tthop. Malay., p.452,n. 3, pi. xliv, fig. 6, male (1886). 



Habitat : West Java {Snellen) ; Perak, Malay Peninsula ; N.-E. 

 Sumatra. 



Expanse ; $, *95 of an inch to 1*15 inches. 



Description : Male. Uppeeside, both wings dark plumbeous- 

 blue, gradually slightly darkening to the outer margins, with hardly 

 any gloss ; an anteciliary black thread. Cilia of the hindwing 

 whitish ; of the forewing whitish at the anal angle, becoming black 

 towards the apex. Underside, both wings French-grey, of a very 

 dark shade for a species of this genus ; the majority of the markings 

 fuscous (not black), outwardly defined with whitish ; a marginal 

 series of fuscous spots ; a submarginal prominent lunular line ; the 

 disco-cellular nervules marked by a fine line, the line defined on both 

 sides by whitish. Forewing with a discal series of five or six spots, the 

 anteriormost of these nearer the base of the wing than the others, 

 these latter placed somewhat in echelon. Hindwing with three basal 

 spots ; the usual irregular discal series of spots, the anteriormost spot 

 much more prominent than the rest and deep black. 

 ' This very distinct species is probably the smallest in the genus. It 

 ■, f- seems to be nearest to C. placida, de Niceville, which is found from 

 Sikkim, through Bhutan, Assam, Burma, and the Malay Peninsula 

 to Sumatra and Java ; differing therefrom in its smaller size, darker 

 (more plumbeous) coloration on the upperside, and much narrower 

 black border to both wings. The markings of the underside are 

 almost identical. I have but little doubt that this is the species 

 figured by Mr. Distant as C. jynteana, var., in spite of his utterly 

 unrecognisable figure of the upperside (for which he apologises) and 

 Mr. Moore's identification of the specimen, as the size agrees with my 

 larger examples, and the underside appears to be correctly delineated, 

 but the species is certainly closely allied to C. placida, and very distantly 

 to C. jynteana, de Niceville. Mr. Doherty identifies this figure with 

 his C. melcena* described from the Tenasserim Valley, and occurs 

 also in North-East Sumatra.
