crimson. All that is left of the humeral stripe is a tiny black spot, often 

 entirely absent and on the sides are two more or less obsolete stripes, 

 one crossing the spiracle, incomplete above, the other on the posterior 

 suture, incomplete below. Beneath the usual black outline of an envelope. 

 Wings hyaline with a very variable, basal spot ; the reticulation bright 

 crimson, this colour extending as far as the apex along the costa and 2nd 

 ners^ure (radius) ; stigma deep blood red with black margins and paler 

 extremities; antenodal nervures 10| to Hi ; the trigone in the hindwing 

 often traversed (in one of ray specimens, this is traversed twice), in some 

 specimens, the trigone of one wing only is traversed ; quite occasionally 

 the costal border of the trigone is strongly convex so that the distal angle 

 meets the 7th nt-rvure by means of an abrupt backward angulation of 

 the latter, this bent part forming a fourth side to the hypertrigone ; in 

 some specimens two cubital nervures are present ; the basal marking a 

 dark amber tint, extending in most specimens as far out in the forewing 

 as the 4th or 6th antenodal nervure, the outer ends of hypertrigone and 

 trigone and a variable area in the anal region. In the hindwing as far out 

 as the 5th antenodal nervure, 2 cells beyond the outer end of the trigone 

 and from thence in a slight analwards curve as far as the termen, the outer 

 part of the loop being excluded. In other specimens the marking is 

 limited to a broad spur in the costal and cubital spaces as far only as the 

 3rd antenodal and not extending into the trigone ; in the hindwing to 

 half-way between the 3rd and 4th antenodals, to the distal end of the 

 trigone and posterior to this as a more or less isolated patch in the anal 

 area, not reaching the termeu or anal margin ; a third form has only dark 

 rays in the inferior costal space, the cubital plus trigonal space and in the 

 hindwing, a small, diffuse, faint spot in the anal area, in which the cell- 

 middles are paler than their margins. (I possess one specimen in which 

 the basal marking is of average extent but is of a smoky brown and in 

 which all the cell middles are clear, the appearance being that of a coarse, 

 brown network.) 



Abdomen brilliant vermilion red with small black middorsal spots on 

 he 9th and 10th segments and occasionally similar coloured, wedge- 

 shaped spots on the distal borders of the 8 and 9th segments. Anal 

 appendages bright red. 



Legs reddish, the inner surfaces of the hind femora black. 



Sexual organs : lobe arched and sloping ; internal tentaculse stout, 

 almost straight hooks ; the lobe long, narrow, straight and projecting. 



Female : Head : eyes reddish brown on summit, lilaceous at the sides and 

 beneath, the beginning of an equatorial ring in front just below and parallel to 

 the cap ; vesicle pale ochreous above, yellow in front ; occiput reddish- 

 brown ; face pale yellow, a deeper colour below ; labrum and labium pale 

 whitish green. 



Prothorax olivaceous with a black collar in front and behind. 



Thorax much paler than that of the male but the markings better 

 defined. The sides generally suffused with a beautiful peach-blossom tint. 



Abdomen brick red on the dorsum, pale olivaceous at the sides where 

 there is often a sufi'usion of peach-blossom tint. Long, hne, subdorsal 

 streaks of black which are almost obsolete on the first few segment, but 

 strongly marked on the 5 th to 9th, absent on the 10th; middorsal, black 

 spots on the 8th and 9th as in the male but somewhat larger. Anal 

 appendages ochreous. 



Legs olivaceous, the coxfB tinted with peach-blossom. 



Wings hyaline ; the basal marking variable, in some specimens only a 

 suspicion of yellow rays in the costal and cubital spaces of forewing 

 and in the hijid reaching as far as the 1st antenodal nervures, halfway
