EURYTELTD.E. 



Hind Wings very broad. Outer margin scalloped. Precostal vein rather oblique, branching at its extremity. 

 Costal vein extending to the outer angle of the wing. Postcostal ai'ising half way between the body and the 

 jirecostal vein, branching at a moderate distance from the base. Upper disco-cellular vein arising quite close 

 to the origin of the postcostal branch, forming the very slightly curved base of the discoidal vein : lower disco- 

 cellular vein nearly straight, slightly oblique, uniting with the median vein close to the origin of its third 

 branch, closing the discoidal cell at about one third of the length of the wing. 



Fore Legs of the male very minute and slender, but slightly and finely hairy. Tarsal portion scarcely half the 

 length of the tibia, simple, exarticulate, and destitute of terminal ungues or spines. Fore Legs of the 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.* 



Four Uind Legs rather short, slender, scaly. Tibia almost destitute of short spines beneath. Tarsus more 

 thickly armed with rows of spines at the sides and beneath. Ungues very slender, curved, and entire. 



Caterpillar rather short, cylindrical, rather attenuated in front. Head armed with two long setose 

 spines. Segments of the body armed with fascicles of short setaj, or with small setigerous tubercles, 

 variegated with spots and oblique stripes of different colours. 



Chrysalis 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 anterior pair 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 under surface tlie spaces enclosed 

 between each pair of dark streaks is of a richer hue than the ground colour of the wings. In their structural generic characters they 

 are, however, very closely allied to the preceding and following genera. 



We are indebted to the assiduous researches of Dr. Horsfield, whilst in Java, for a knowledge of the transformations of Erg. Coryta, 

 the larva of which, as described above, and as figured by Dr. Horsfield, approaches very closely to tliose of several genera of 

 Nyniphalid:e, especially Epicalia, GynKcia, and Myscelia ; indeed the larva of the species to which Cramer, with a singular coincidence, 

 applied the name of Ariadne (and of which the transformations are given by StoU, Suppl. Cram. pi. 4. fig. 4. A. B.), is quite like that 

 of Ergolis Coryta. It will be seen, by referring back to p. 226.. that the relations of Myscelia are by no means satisfactory, and a 

 detailed examination of the arrangement of the wing-veins of these and allied genera will, I feel convinced, either prove the 

 impropriety of the adoption of the present as a distinct family, or will render the admission of other genera, which have already been 

 arranged with the Nymplialida;, necessary.

Body slender, moderately woolly ; wings of moderate size, of a rich orange colour above with black markings, but 

 not ocellated, alike in both sexes. 



* Dr. Horsfield's figures of the fore legs of this genus {Drsc. Cat. Lcp. pi. 7. f- 6- c and f.) do not give a precise idea of their structure, the tarsus of the 

 male and the femur of the female being represented as articulated.
