ON NEW AND LITTLE-KNOWN BUTTERFLIES. 247 



(1900), gives only three species of Ct/an/r/s, from iSuiiiatra, 

 cosscva^ coma and cori/thus, all described by m^'self, and five from Java 

 akitsa, Horsfield, pitspa, HorsfioKl. coahl(%, do Niceville, and cafreus 

 de Nic^ville. He records C. ceyx with a query from Java ; 1 possess 

 seven males from thence, and three males and a female from 

 Celebes. Ho says he has specimens of C. cci/.v from Foo Chow iu 

 China ; those j^robably represent a distinct species, as excepting 

 C. akasa, Horsfield, and C. jntspa, HorsHold, the orient.d species 

 of the genus are not widely distributed. As regards C. wm, de 

 Nic^ville, he notes " Mr de Niceville knows his genera of Li/ccvn/dce ; 

 otherwise, I should certainly have supposed this to bo a J.i/canesthes 

 near to L. tunicri^ Miskin ''. But the last named species has tho 

 apex of the forowing in the males typically produced, while C. cam 

 has it rounded as is typical of the genus Ci/aniv/'it, and the latter 

 has no sign of the ciliated "tales" to tho himhving usually found 

 in Lycoimstlies. I think tlioroforo that C. ('(JAfis a true Cyaniris.

Habitat : N.-B. Sumatra ; W. Java. 



Expanse : ^, Ivl to 1*2 inches. 



DESCiurTiON : Male. Nearest allied to iY. hhutea^ de Nic^villo, 

 from Sikhim, but is tailless, whereas that species is tailed. Uitee- 

 siDE, both lohigs similar to those of that species. Underside, both 

 wings with the ground-colour more ochreous. Forewing with the 

 spots fornn'ug tho discal oatonulated band separated further from 

 one another, the band nu)re regular, the spot in the first meilian 

 intorspaoo nearer tho margin of the wing, and with an additional 

 spot behind it in tho submodian interspace; ;uui, most iniporlanl. of 

 all, tho base of the wing up to and including the si)ot in the midillo 

 of the discoidal coll heavily clouded with fuscous ; otherwise similar. 

 Hindwing as in N. bhutea. 



This species differs markedly from the same sex of Iho tailless, 

 form of iV. nore'ia, Folder, in its larger size, more pointed n])ex 

 and straighter outer margin of tho forewing, and on tho underside 

 of the forewing in tho discal baud forming a regular curve instead 

 of being dislocated behind the second modinn nervule. 'fhe l)hu!k 

 clouded base of the wing will distinguish it from all the siiecios 

 of Nai'aduba known to nu). Mynheer P. C. T. [Snellen has 

 kindly sent mo coloured drawings of his Ltjavna datariai and
