NYMPHALID^. NYMPHALIN^. ERGOLIS. 7 



Ergolis, Eiirytela and Byblia certainly seen to form a connecting link between the 

 Salyrina:, Elymniincs and the NytnphalincE, the structure of the larva and the swollen costal 

 nervure being important points of connection. Mr. Distant in his " Rhopalocera Malayana" 

 places them at the head of his synopsis of the genera of Nymphalince, but afterwards 

 describes them near the middle of that subfamily, and adds that he is "not at all satis- 

 fied with the position in which" he has "placed these genera." Nor am I satisfied with 

 the position they here occupy ; they form a small and anomalous group, and it would perhaps 

 have been better to have erected them into a subfamily under Westwood's name.

"Body, moderate-sized ; Tuings, large, broad, thickly ornamented above with numerous 

 slender, dark, undulating lines. Bead, small, clothed with short scaly hairs. Eyts, 

 moderate-sized, naked. Antennce, slender, about two-fifths of the length of the forewing, 

 terminated by a very slight and gradually-formed club, obtuse at the tip, and not more than 

 double the thickness of the basal part of the antennas. Palpi, porrected, but slightly curved, 

 extending considerably beyond the length of the head, and not elevated above the middle 

 of the eyes ; the terminal joint a little deflexed at the tip, parallel, finely hairy beneath, the 

 upper edge with a ridge of short hairs from the middle to the end ; terminal joint elongate- 

 oval, slender. Thorax, oval, woolly in front. Abdomen, slender. Forewing, large, well arched 

 along the costal margin ; outer margin irregularly waved, about two-thirds of the length of 

 the costal ; inner margin nearly straight, about one-fourth longer than the outer, so that the 

 wing appears nearly truncate at the tip. Fm/.f arranged nearly as in .ffwrj/f/ff. Costal nervure 

 dilated at the base ; upper disco-cellular nervule very short, oblique ; the extremity of the \7ipper'\ 

 discoidal nervule extending into the most prominent of the angulations of the forewing ; 

 middle disco-cellular considerably longer, curved at its base, its extremity directed outwards 

 longitudinally, forming the base of the lower discoidal nervule ; lower disco-cellular very 

 slender, nearly transverse, uniting with the third median nervule just beyond its origin, 

 closing the discoidal cell at about one-third of the length of the'wing. HiNDWiNG, very broad, 

 outer margin scalloped. Prcecostal iiervure rather oblique, branching at its extremity ; costal 

 extending to the outer angle of the wing ; subcostal arising half way between the body and 

 the prjecostal, branching at a moderate distance from the base ; tipper disco-cellular nervule 

 arising quite close to the origin of the subcostal branch, forming the very slightly curved base of 

 the discoidal nervule ; loiver disco-cellular nearly straight, slightly oblique, uniting with the 

 median nervure close to the origin of the third median nervule, closing the discoidal cell at about 

 one-third of the length of the wing. Forelegs of the male very minute and slender, but slight- 

 ly and finely hairy ; tarsal portion scarcely half the length of the tibia, simple, exarticulate, and 

 destitute of terminal claws or spines ; of iht female somewhat longer than those of the male ; 

 femur rather shorter than the tibia and tarsus united ; tibia and tarsus of nearly equal length, 

 slender, cylindrical, scaly ; the tarsus scarcely dilated at the extremity, where it is articulated ; 

 the joints with very short spines at their extremity beneath. Middle and hindlegs rather 

 short, slender, scaly ; tibia almost destitute of short spines beneath ; tarsus more thickly 

 armed with rows of spines at the sides and beneath ; claius, very slender, curved and entire." 



'• Larva, rather short, cylindrical, rather attenuated in front ; head armed with two long 

 setose spines ; segments of the body armed with fascicles of short setae, or with small 

 setigerous tubercles, variegated with spots and oblique stripes of different colours. Pupa, 

 rather elongated ; head-case obtusely pointed ; thorax-case with an obtuse tubercle on the 

 back ; base of the dorsum of the abdomen with a larger obtuse tubercle." 



"The very broad form of the wings (the forewing appearing almost transversely 

 truncate), and the slender undulating black streaks with which they are adorned on both 

 sides, at once distinguish the species of this genus. On the underside the spaces enclosed
