way from the origin of the second superior nervulc to the tip of the wing; the fourtli 

 arising midway betAveen tlie base of the tliird and the tip of tlie wing. Fore wings 

 witli a very l)road mesial white belt, which scarcely fails of attaining either border, 

 broken only by the black nervnles Avhich cross it and the few black scales which bor- 

 der the nervnles for a short distance on the outer lialf of the belt ; the belt varies 

 slightly with each interspace and is usually broadest next the cell and in the lower 

 median interspace; in the subcostal interspaces, its width is fully twice the breadth 

 of the interspaces; its interior border is well defined, its exterior a little vague by the 

 intermixture of white and black scales; the belt starts from a very little beyond the 

 middle of the costal border and, curving outward, reaches the inner Ijorder at a dis- 

 tance from the outer margin equal to its own width ; the interior margin of the belt 

 is nearly continuous, but is almost always angularly indented to a considerable degree 

 at and just above the lower median nervule; the exterior margin is less regular, being 

 usually i)rotuberant beyond the cell and in the lower median interspace and indented 

 somewliat just beloAv the lower median nervule ; at the terminal divarication of the sub- 

 costal nervure there is a white dot and just within it, above and below the divaricat- 

 ing nervule, two small triangular patches of white scales ; there is a faint, submarginal 

 series of transverse, disconnected, bluish streaks in every interspace, distant from the 

 border by about three-quarters the Avidth of an interspace, and occasionally the slight 

 indication of a second row between this and the border; fringe alternately black and 

 white is about equal measure, the b!ack next the nervure tips. Hind vnnrjs resembling 

 in form those of B. astyanax in evei-y particular, but differing from those of B. archip- 

 pus in having the outer border pretty strongly crennlate, more strongly arched and 

 slightly (?) or rather conspicuously {$) produced at the upper median interspace. 

 First median nervule originating a little further from the base than the last subcostal 

 nervule. A broad, Avhite mesial band, similar to that of the fore wings and in continu- 

 ity with it, is broadest in the middle and tapers slightly toward either end ; its interior 

 border is well defined, nearly straight, the middle two-thirds slightly convex; its ex- 

 terior border is regularly convex and a very little poAvdery ; the band starts from the 

 middle of the apical two-thirds of the costal border and reaches the inner border at the 

 middle of the apical half ; this belt is f olloAved exteriorly by a series of clustered blue 

 scales, forming, in each interspace, lunular cappings to a roAv of small and usually rather 

 inconspicuous, round, orange red spots, subparallel to the outer border; both of these 

 roAvs of colored spots are often greatly subdued and occasionally absent; there is a 

 double sul^marginal roAv of slightly curved, transverse blue streaks, one in each inter- 

 space, the inner slightly larger and more curved, distant from the margin by the width 

 of an interspace, the outer midAvay betAveen the inner and the border, each streak 

 usually broken in the middle. Fringe AA^hite, interrupted rather broadly Avith black at 

 the nervure tips. 



Beneath : Fore icings ; there is a mesial Avhite belt partaking altogther of the char- 

 acter of that of the upper surface, excepting that it is slightly broader; within this 

 belt the Aving is of a rich, dark purplish broAvn, a little tinged Avith olivaceous beside 

 the veins; the extremity of the cell is marked by a large, transverse, dai-k orange red 

 spot, bordered Avith purplish black ; and in the middle of the cell is another large, 

 roundisii or irregular spot of the same colour similarly bordered ; both occupy the 

 Avhole breadtli of the cell, and on either side of the latter, at the uppermost extremity, 

 is a slight patch of bright pale blue scales ; a few inconspicuous blue scales are also 

 scattered through the other unoccupied parts of the cell ; the space between the costal 

 nervure and the margin is dark orange red ; outside the belt, the subapical Avhite spots 

 and the tAvo submarginal roAvs of blue streaks found on the upper surface are repeated 

 beneath, both of the latter Avitli etjual distinctness and on a purplish black ground; 

 foUoAving the sul)marginal streaks, interiorly, is a rather broad dark red band, varying 

 in tint from orange to cinnanioneous, most conspicuous above the middle of the median 

 area; Avhen it is of the latter tint, the space betAveen this and the mesial belt — except- 

 ing the subapical Avhite spots Avhich are sometimes foUoAved by other faint spots below 

 in succeeding interspaces — is also cinnanioneous; othenvise it is of a dark oliA-aceous
