X. busiris is found in the Malay Peninsula, extending northwards as far as Upper 

 Tenasserim, where Limborg took it near Moolai at 3,000 to 6,000 feet altitude ; and Captain C. 

 T. Bingham also took it in the Uonat range and the lower Thoungyecn forests in April. All 

 the specimens we have seen are males. 



The figure shows the upper and undersides of a male specimen in Major Marshall's 

 collection taken in Upper Tenasserim. 



Genus 34.-ZEUXIDIA, iiiibner. 



Ztuxidia, Hiibuer, Samml. Ex Schmett. (1S16-1S24) ; id., Westvvood, Gen. D. L., p. 327 (1851). 

 Body very hairy. Head moderately large, hairy; eyes large, prominent, naked; falpi 

 elongate, compressed, erect, the third joint rising above the level of the top of the head, thickly 

 clothed with appressed scales in front, slightly hairy at the back of the middle joint ; terminal 

 joint slender, well-defined, and rather long ; antenius rather less than half the length of the 

 forewing, slender, the articulations rather long, distinct ; the club very slender, elongate, gradu- 

 ally formed and slender at the tip. Forewing large, triangular, the costa convex ; the apex 

 acute ; the outer tiiargin oblique, slightly concave ; the hinder angle rounded, the inner inargin 

 convex in the male. The first siibeostal nervule given off before the end of the cell, about 

 three-fourths its distance from the base, and anastomosed with the costal nervure ; the second 

 emitted before the end of the costal nervure ; the third and fourth close together towards the 

 apex ; the tipper disco-cellular obliquely directed outwards, the second twice as long and in a 

 straight line with the upper portion of the lower, which is very long and slightly concave, 

 joining the median nervure midway between the points where the second and third median 

 nervules are given off; the median nervure continued beyond the point where the third median 

 nervule is given off in a short outwardly curved spur not reaching the lower discoidal nervule, 

 which spur is merged in the fold of the wing, giving the appearance of a fourth median 

 nervule ; the submedian nervure straight for a short distance from its base, then angled, and 

 following the contour of the convex inner margin. Hindwing large, {\\Q.cosla convex, the apex 

 rounded, the outer margin convex, and produced at the anal angle into a distinct narrow but not 

 acute tail ; the inner margin highly convex and channelled to receive the abdomen ; the 

 discoidal nervule almost straight in continuation of the subcostal ; an incomplete loiuer disco- 

 cellular nervule originating at the point on the median nervure where the third median nervule 

 is given off, and not reaching the discoidal nervule, but becoming merged in the wing mem- 

 brane which is discoloured with yellow at its termination, thus only partially closing the 

 discoidal cell. Forelegs of the male very slender, scarcely hairy ; tarsus about half the length 

 of the tibia, and equally slender ; femur about as long as the tibia but not so slender. Of the 

 female rather longer and more robust, tibia rather shorter then the femur, tarsus two-thirds of the 

 length of and rather thicker than the tibia, spiny along the whole length beneath. 



.About eight species of the genus Zcuxidia are known, all from the Indo-Malayan region. 

 The outline of the wings is very similar indeed to that of Kallima {Nymphalincv, a genus com- 

 prising the great " Oak-leaf" Butterflies of India), but the outer margin of the forewing is less 

 convex and angled near the hinder angle, and the pattern of the underside is difTerent ; in 

 Kallima the discal line extends from the apex of the forewing to the anal angle of the hindwing 

 like the midrib of a leaf ; and there are no ocelli ; in Zcuxidia the discal line commences from the 

 middle of the costa of the forewing, and the hindwing has two ocelli. The upperside of the 

 males is somewhat similar in colouring to the amythaon group of Amat/nisia, but the hindwing 

 has usually also a patch of bright blue. But in addition to the structural characters noted above 

 perhaps the most remarkable features of the genus are the secondary sexual characters of the male 

 insect. There are no lateral tufts on the abdomen as in Amatkicsia phidippus, but the hindwing 

 bears no less than three. The submedian nervure is sunk in a fold and angled at a short distance 

 from its base where it bears a thick tuft of long bright brown coarse hairs, and the edge of the 

 fold above is thickly covered with finer vvooly hairs ; in the discoidal cell there is an oval
