RHOPALOCERA MA LA VAX A. 37I 



anterior wings spotted as above; posterior wiugs with about the basal half pale greyish, the costal area 

 and a patch at base of cell fuliginous. Body more or less concolorous with wings. 



I -a;-.— Posterior wiugs above having the transverse, discal macular fascia narrower than in specimen 

 figured, and the pale coloration at abdominal margin also considerably more restricted. 



Exp. wings, 47 millim. 



Hab. -Malay Peninsula ; Province Wellesley (coll. Dist.) ; Malacca (Pinwill— Brit. Mus. ; coll. Staud.) ; 

 Singapore (Godfery— coll. Dist.).— Sumatra (Hewits.).— Borneo (iJruce). 



The above described varietal cliaractcrs may possibly be of a sexual nature, luit the 

 material now before the writer is not sufficient to warrant a conclusion on that point.

Wings above dark fuliginous ; anterior wings with eight pale irregular spots, of which four are in 

 oblique series from upper discoidal nervule to lower median nervule, three divided by the fourth and fifth 

 subcostal nervules, and one in cell ; posterior wings with the disk pale greyish. Wings beneath somewhat 

 paler than above ; anterior wiugs spotted as above, and with some submarginal greyish streaks near apex ; 

 posterior wings with the pale discal area much larger than above, and extending to the outer margin 

 between apex and median nervules. Body more or less concolorous with wings. 



Exp. wings, 55 millim.

Genus LOTONGUS. 



Lotuni/us, Distant, antea, p. 3G9. 



This genus is allied to Unbina in having the outer margin of the anterior wings a little longer than 

 the inner margin, but differing by having the upper disco-cellular nervule of the anterior wings only slightly 

 longer than the lower, and the disco-cellular nervules suberect, aud not oblique as in Unkana,.* 



Two species belonging to Lutongus are found in the Malay Peninsula, aud arc here 

 enumerated. 



1. Lotongus calathus. (Tab. XXIV., fig. 14.) 



Kiulaiiius Oilathits, Hewitson, Ann. & Mag. Nat. Hist. ser. 4, vol. xviii. p. 353 (1876). 



Wings above dark fuliginous ; anterior wings with three large pale contiguous discal spots situate one 

 in and near end of cell, and two beneath divided by the second median nervule, a small pale spot near 

 centre of submedian uervure, and a smaller aud more obscure pale spot beyond cell ; posterior wiugs paler 

 than anterior with the apex and the fringe pale ochraceous. Wings beneath as above, but anterior wings 

 having the pale discal spots united to the costa aud to the inner margin by pale greyish ochraceous; 

 posterior wings having the apes more continuously pale ochraceous than above. Body more or less 

 concolorous with wings. 



Exp. wings, 47 millim. 



Hab.— Alalay Peninsula; Malacca (Biggs— coll. Dist.).— Sumatra (Hewits.). 



* The writer has thought it best, m describmg genera belonging 10 the Hesperiidce, to give compai-ative, rather than 

 more exhaustive but less easily understood diagnosis.
