 sometimes pectinated ; forewing elongate triangular, the costa straight, the apex 

 snbacnte; hindwing of <J with apex rounded ; palpi upcurveil in frout of face, the 

 second segment well-haired ; the third erect ; legs of S all hairy ; the mid and 

 hind tibiae broadly fringed ; the fore coxae and femora hairy ; forewiugs fawn-

117. Bessacta javensis spec. nov. 



Resembles B. pectinata Hmps. in the structure of the antennae of the c?, but 

 se])arated by numerous differences in the shape and arrangement of the black 

 markings, in some of which it is nearer to pobjupila Wlk. 



I'orewinq : with the ochreous ground colour suffused with brownish grey and 

 dusted with fuscous, the costal edge remaining yellow ochreous ; the inner line 

 runs obliquely outwards, pale, to median vein, marked by dark dots on subcostal 

 and median, joining there the black blotch, which is somewhat broader and not 

 pointed at top, preceded on inner margin by a diffuse black spot, and followed 

 immediately on median vein by two black spots with pale edges, of which the 

 round upper one represents the orbicular stigma ; reuiform broader and more 

 conical, the black blotch below also broader and reaching inner margin, more 

 plainly marked by slight yellow curved lines ; vein 3 and the other veins towards 

 termen more prominently yellowish ; the black luuules before outer line only four 

 in number, the fifth being confluent with the reniform ; the black apical blotch 

 larger ; the quadrate black blotches before subtermiual line larger and with a 

 narrower one above tliem ; the lower two of the other three spots larger and 

 rounder ; the space between the lines black ; the terminal black spots larger 

 and the fringe darker-mottled. 



Hincluing : with the basal area more conspicuously pale. 



The underside of wings, the head, thorax, and abdomen do not appreciably 

 differ from those oi pectinata, with which it also agrees in siise. 



1 c? from Java. 



118. Bessacta columnaris spec. nov. 



Forewing : quite pale ochreous, faintly speckled and tinged with grey-brown ; 

 all the veins and margins of the black marks conspicuously pale ochreous ; subbasal 

 line represented by two black spots, above and below subcostal vein ; inner line 

 marked by black dots on costa, subcostal, and median veins, the last followed by 

 a subquadrate spot in cell, obliquely below which is a large trapezoidal blotch in 

 submedian interval, and below vein 1 nearer base a smaller black blotch traversed 

 by a pale line; reniform stigma bluntly conical, forming with the black blotches 

 below it a })illar-like mark with pale uneven edges, quite separate from the five 

 black spots before outer line, which is bent inwards along vein 3 ; the .pale edgings 

 of the submarginal black blotches broader, the upper ones three in number 

 like the lower ; a row of black terminal triangles edged with pale ; fringe pale 

 ochreous. 



Hindwing : fuscous, paler basewards, with a pale sinuous outer line before the 

 darker terminal border ; cell-spot dark ; fringe pale. 



Underside grej-ish ochreous, the terminal area of forewing diffusely fuscous.
