RHQPALQCERA MALAY ANA. 



pale bluish, the posterior margin black, inwardly bordered with white near anal angle, where there are 

 two transverse black marginal spots, the fringe white; tail-like appendages blackish with marginal white 

 fringe; costal area pale hyaline, darker near base, upper portion of cell and basal area between subcostal 

 nervules talc-like, and pale transpatvnl slmmim-ons. above, beneath, and beyond which the colour 

 is fuscous. The anterior wings beneath reddish ochraceous, a broad basal and a transverse central 

 fuscous streak in cell, a pale fuscous line at end of cell, and two transverse, narrow, waved fuscous 

 fasciae between end of cell and outer margin. Posterior wings greyish -white, the costal margin more 

 or less suffused with reddish ochraceous, and with ten large fuscous discal spots, the upper six of 

 which are Buhqnadrate but irregular in size, and the posterior four are more irregular in shape, and 

 have their centres more or less greyish; a submarginal and marginal fuscous line, the first of which is 

 broken and irregular, aud between which and the margin is a narrow fuscous streak, leading to a long, pale 

 bluish fuscous spot ; beneath the submargiual line near abdominal margin are two narrow ochraceous 

 fascia;, which amalgamate inwardly, and between which the colour is pale metallic bluish. Body above 

 fuliginous-brown, beneath greyish -wh ite ; legs greyish-white, annulated and streaked with fuscous- 



Female. Wings above much paler than in malr, and the posterior wings pale fuliginous-brown, 

 excepting near anal angle, where there is an obscure bluish patch with a few obscure fuscous marginal 

 spots. Wings beneath as in male, but with anterior wings paler in hue. 



Expanse of wings, 85 to 38 millim. 



Hjlb. — Malay Peninsula; Province Wellesley (coll. Dist. & Sauer) ; Perak (Townsend— coll. Godiu. 

 and Salv.) ; Stmgei Gjong (Durnford); Malacca (Biggs) ; Singapore (Kerr— coll. Dist.) — Sumatra (Wallace 

 —coll. Dtet* k Moore). — Daat Island (coll. Diat.), 



This species varies very much in size, and is probably somewhat widely distributed. It is 

 allied to the Mtjrina ravimlra, Hurst'., a Javan species which belongs to, and is the type of, this 

 germs. We thus find D. moorei inhabiting Borneo, Sumatra, and the Malay Peninsula, and 

 differing from a closely allied Javan species, as is so frequently the case in all branches of 

 Malayan Zoology, and has been so well and ably pointed out by Mr. Wallace. 



Genus BIDTJAKDA, gen. no v. 

 Biduandat Distant, anim, p. 23a. 



Anterior wings globosely subtriangular, the costal margin arched, the outer margin convex, the inner 

 margin nearly straight. Costal nervure terminating on costa before the apox of cell; first subcostal 

 nervule emitted about the middle of cell, second about midway between tirst and thud, the last of which 

 arises a little before end of cell, third and fourth bifurcating at a short distance from apex of wing ; 

 disco-cellular nervules somewhat perpendicular; first median nervule emitted at end of cell, second nearer 

 to first than third, which is emitted beyond middle of cell. Posterior wings subovate; costal margin arebed 

 at base, and then straight and strongly oblique to apex, which is obtuse ; posterior margin as in Drupadia, 

 the abdominal margin augulated but not so suddenly cleft as in that genus. Costal nervure reaching apes 

 of wing ; otitt r neuration much as in l>ntpndia. 



The species included in this genus were given me by Mr. Moore as forming part of his 

 genus Jjrupadiii, the description of which is promised to be published in a forthcoming part of 

 the * Journal of the Asiatic Society of Bengal/ As they, however, possess four subcostal 

 nervules to the anterior wings, whilst the species of Drupadia are provided only with three, 

 it became necessary to form a new genus for their reception. Mr. Moore takes the MijriiKt 

 ravindra, Horsf,, as the type of Drupadia, and the type of Biduanda must be found in the 

 Myrina tkesmia, Hew.
