328 NYMPH ALID.E. 



Antennce about half the length of the fore wings, slender, slightly curved at the base, and with the tips deflexed ; 

 articulations elongate, distinct, the tips of each being rather thickened ; the club is gradually formed, but 

 slender, finely carinated beneath ; the seven terminal articulations gradually acuminated, the exti'eme tip being 

 very slender and acute. 

 ThOEAX oval, hirsute, rather small. 



Fore Wings large, subtriangular, pointed at the tip. Fore margin very much arched ; apical angle acute. Apical 

 marginabout three fourths of the length of the anterior; posterior angle rounded. Inner margin of the same 

 leno-th as the apical, very mucli dilated and rounded in the male, nearly straight in the female. Costal vein 

 extending about five sixths of the length of the costa, being united witli the costa before its extremity by two 

 slender oblique veinlets. Postcostal vein throwing oif its first branch at about one fourth of the length of the 

 wing; this branch is united with the costal vein before the emission of tlie first veinlet connecting the costal 

 vein with the costa (wliich veinlet must therefore be regarded as the normal extremity of the costal vein, the 

 second oblique little veinlet connecting the costal vein with the costa being the termination of this first postcostal 

 branch): second branch of the postcostal vein arising aljout half-way between tiie anterior extremity of the 

 discoidal cell and the tip of the wing, very short and oblique ; forming, in fact, a connecting veinlet between 

 the postcostal and the costal veins, pi-evious to the emission of the second little veinlet connecting the costal 

 vein with the costa, which I have above considered as the representative of the termination of the first 

 postcostal branch, and, consequently, the portion of the apparent costal vein beyond this second veinlet must be 

 considered as the real termination of the second postcostal branch : third and fourtli postcostal branches arising 

 close together, at about the distance of five sixths of the length of the wing. Upper disco-cellular vein 

 extremely short, scaixely distinct, arising at rather more than one third of the length of the wing ; middle 

 disco-cellular very short, transverse ; outer disco-cellular very long, oblique, and curved, uniting with the third 

 branch of the median vein at some distance beyond its origin, closing the discoidal cell in an acute point about 

 the middle of the wing ; this third bi'anch of the median vein also throws off a short oblique branch at the like 

 distance beyond the extremity of the outer disco-cellular vein, directed towards the tip of the wing, but not 

 reachino- the second discoidal vein ; the wing exhibiting a fold between its tip and the apical margin, like a 

 fourth branch of the median vein. 



Hind Wings elongate-triangular. Costal margin rounded ; outer angle rounded. Outer margin entire, rounded ; 

 anal angle produced into a tail, the sides of which are traversed by the first branch of the median and the 

 submedian veins. Precostal vein curved towards the body at the tip. Costal vein scarcely extending more 

 than half the length of the costa. Postcostal vein branching at a little distance from the base. The discoidal 

 vein not angulated or curved at its base, forming a contiimous line with the base of the postcostal vein. 

 IMedian veinwith its third branch arising at about half the length of the wing, angulated at the same distance 

 from its base as exists between the first and second branches ; emitting a transverse veinlet from the angle, 

 which is terminated abruptly before it reaches the discoidal vein ; thus nearly closing the discoidal cell, which 

 is rather narrow, beyond the middle of the wing. On the upper side, the disc is marked with an oval patch of 

 pale buff hairs, in the space between the base of the costal and postcostal veins ; there is also an elongate-oval 

 patch of brown hairs in the middle of the discoidal cell, lying longitudinally, and a row between this patch and 

 the inner edge of the discoidal cell, lying obliquely towards the abdomen. Disc of the under side of the hind 

 wings traversed by an oblique dark line, which extends to the middle of the costa of the fore wings, beyond 

 which are two ocelli, wide apart ; the sides of the tail are also marked with two pale longitudinal lines. 



Fore Legs of the male small, pectoral, slender, thickly clothed with fine woolly hairs from the base to the tip, 

 Tarsus about half the length of the tibia. Fore Legs of the female rather longer and more robust than those 

 of the male. Tibia rather shorter than the femur. Tarsus two thirds of the length of, and rather thicker 

 than, the tibia, spiny along the whole length beneath ; basal joint occupying two thirds of the length of the 

 tarsus ; second, third, and fourth gradually shorter and transverse, each with long spines beneath ; terminal 

 joint simple. 



Four Hind Legs long and scaly. Tibia longer than the femur, slightly spined beneath ; tibial spurs strong. 

 Tarsus as long as the tibia, with four rows of spines beneath ; joints gradually becoming more slender to the 

 tip. Claws rather small, acute, and curved. Paronychia small, bifid; upper division longer and slender. 

 Pulvillus broad. 

 Abdomen rather small. 



Transformations unknown. 



This genus is perhaps too nearly allied to Amathusia, from wliich, however, it is at once known by the acute fore wings, the hind 

 wings terminating at the anal angle in a pointed tail, and especially the arrangement of the veins of the wings, which I have carefully 

 described, as I find them incorrectly re|)resented, in several respects, in Ilerrlck vSchaffer's sketch, published in the Ahhandlungen des 

 Zonhgisch-mineralogischen Vereines in Regevshurg (8vo, 1849, pi. 3. f. 23.), and which is the more to be regretted, as this is the wing 

 which that writer has selected to illustrate the typical arrangement of the veins of the Diurnal Lepidoptera. 



The general character of the markings of the wing in this genus closely resembles that of Amathusia Amythaon, the same beautiful 

 lilac bar occurring in the males of both. The females are more varied in their markings than the males ; but the colour of these marks 

 does not exhibit so great a contrast as in A. Amythaon. 



As in several of the adjacent genera, the male has the disc of the hind wings adorned with elongated tufts of hairs, which, I imagine, 

 the insect has the power of raising and depressing at will.
