RHOPALOCERA MALAY AX A. 239 



black spots with scattered bluish scales anil inwardly margined with ochraceous, separated by the median 

 nervules, and a pale bluish streak inwardly margined with l)laek and outwardly with ochraceous at anal 

 angle. Body above and beneath more or less concolorous with wings. 



Male. This sex is not known to the writer, ])ut has been figured by Mr. Hewitson, and descril)ed as 

 "Anterior wing dark brown. Posterior wing l)rilh";uit lilue."* Wings beneath apparently as in female. 



Exp. wings, 5 , 28 millim. 



Hab.— Burma; Motilmein (Horsf. & Moore). — Malay Peninsula; Malacca (Pinwill — Brit. Mus.) ; 

 Singapore (Wallace — coll. Dist.). ^Borneo (Druce^. 



Mr. Hewitson, who hatl the opportniiity of examining several specimens, states that 

 " on the underside this species varies considerahly in the form of the hne which crosses the 

 anterior wing beyond the middle, as well as in the size of the black spots of the posterior 

 •wing." It appears to be a moderately scarce species, or at all events is uncommon in average 

 collections made in the Malay Peninsula. 



Genus SEMANGA, gen. nov. 



Semanf/d, Distant, antea, p. 233. 



Anterior wings somewhat short and broad, costal and outer margins slightly convex, inner margin 

 very slightly concave. Costal uervure terminating on costa a little before end of cell, where it is somewhat 

 recurved ; first subcostal nervule emitted at about one-third before end of cell, second about midway 

 between first and third, third at end of cell, third and fourth bifurcating at about two-thirds the length 

 of third ; disco-cellular nervules somewhat oblique ; first median nervule emitted at about end of cell, 

 the second emitted about two-thirds nearer the base of first than base of third. Posterior wings subovate, 

 the costal margin rounded at base and then straight and oblique to apex, which is obtuse ; posterior 

 margin rounded, very slightly waved or scalloped, with three slender tail-like appendages situate at the 

 apices of the median nervules ; abdominal margin concavely excavated a little before anal angle. Costal 

 nervure extending to about apex ; costal nervules bifurcating a little before end of cell, and opposite to the 

 apparently common origin of the first and second median nervules ; submedian nervure slightly curved 

 outwardly, internal nervure strongly curved inwardly. Palpi robust and porrect, the second joint clothed 

 with coarse and closely compressed hairs and extending for two-thirds its length before eyes ; ajjical joint 

 much more slender than second, but moderately robust. Body robust. 



Semaiiija is founded on a species already received from both Borneo and the Malay 

 Peninsula, and its colour affinities are with Catapacilma, especially by the metallic markings of 

 the under surface of the posterior wings ; an additional subcostal nervule to the anterior 

 wings, however, sufficiently separates it from that genus.

Female. Anterior wings above dark violaceous, with the costal and outer margins (broadest at apex) 

 dark fuscous ; posterior wings with the costal, posterior and abdominal margins fuscous, the posterior 

 margin darkest, and containing some irregularly sized and arranged ochraceous submargiual spots, one 

 between the lower submedian nervule and submedian nervure, and one at lobular anal angle, each 



* Mr. Hewitson also appends to this description. '■ with one taih" which is clearly erroneous, and probaldy referred to 

 a mutUated specimen ; he has also figured the female much in the same way. and probably from llie same cause. My m\\\ 

 figm'e is more or less imperfect for a similar reason.
