NYMPHALID^. SATYRIN^-. MYCALESIS. 103 



space between the base of tlie wing ami the first branch being proportionately sliortcned ; 

 in others the base of this nervine is swollen, and the space between the first and second 

 branches as short as nsual ; siibmedian nervure simple, and curved at the base in some 

 species, which have a slit enclosing a tuft of hairs opposite the origin of the first 

 median nervule ; but greatly swollen at the base in other species which have not this slit,* 

 the tuft of hairs in these being placed on the upper surface of the hindwing. Hindwing 

 with the costal nervure extending about two-thirds of the length of the costa ; subcostal 

 nervure arising opposite the origin of the precostal, its branch arising at a considerable 

 distance from its base ; the disco-cellular nervules forming a nearly continuous, rather obliquely 

 transverse, termination to the discoidal cell, uniting with the median nervure exactly at, or 

 a little beyond, the origin of its tliird branch ; the discoidal cell in some species bears along 

 its outer edge a tuft of long pale hairs, whilst in others it is more generally clothed with 

 numerous sliorter hairs ; otiter mariiin slightly scalloped. Forelegs of the male small ; 

 ftninir clothed with scaly hairs, slender, as long as the tibia and tarsus, which are thickly 

 clothed with short hairs. Forelegs of the female much longer, slender ; tibia rather 

 shorter than the femur or tarsus, which latter is articulated, the articulations armed with short 

 spines beneath ; the tips destitute of claws. Four hindlegs rather long and slender, scaly, 

 destitute of hairs, and with only a few very small spines on the sides of the tibice beneath ; the 

 tarsi almost destitute of spines, and thickly squamose ; the scales hiding the terminal claws." 



"The species of Mycalesis are distinguished by their uniform dull colours, being generally 

 either black or brown, occasionally varied by a single large eye-like spot on the forewing, 

 with a few ocelli near the outer margin of the hindwing. On the underside they are often 

 marked with a pale slender oblique bar running across both wings, with the ocelli larger, 

 and often elegantly tinged with silver." (Dottbleday, 1. c.) 



Larva and Pupa unknown. 



The species present numerous structural differences though maintaining the same general 

 type and style of markings. The African species appear to form a distinct group ; and recently 

 Mr. F. Moore (Trans. Ent. Soc. Lond., 1880, p. 155), has divided the Asiatic species into 

 no less than twenty-three distinct genera, of which twelve are represented in India ; these 

 divisions, if accepted, must be carried still further as will be seen further on ; but as some of 

 the structural features common to both sexes on which reliance is placed in separating the 

 groups, vary in aspect in the sexes of the same species, it is clear that they can only be 

 accepted as generic differences with reservation. The divisions as usual rest chiefly on the 

 structure of the male insect, and especially on the presence and position of the sexual scent- 

 pouches or glands, and the tufts of hair which usually accompany tliem, and so far as these 

 features go the divisions are more satisfactory. The Indian species of Mycalesis come under the 

 following groups : — 



Zey to the Indian G-roups of Mycalesis. 



A. Males with a glandular pouch and tuft on both wings. 



a. Males witJi the pouch and tuft on hindwing near to the subcostal nervure, and overlapped 

 by the forewing. The eyes hairy. The costal, median, and submedian nervures of fore- 

 wing much swollen at base. 



«'. With a glandular patch of raised scales on the middle of the submedian nervure of 

 X}ciQ forewing partly covered by a tuft of long fine hairs. 



«^, With the first subcostal nervule of hindiving of male much curved 

 upwards at base, then straight ; the second very concave from base 

 of first to end of cell. 



I. ViRAPA. 



b~. With the first subcostal nervule of hindwing of male swollen at basei 

 and covered on upperside by a tuft of hairs. 

 II. Gareris. 

 i'. With a slight tuft, but no perceptible patch of raised scales on the submedian 

 nervure oi forewing beyond the swollen base. The first subcostal nervule 

 of hindwing in male not curved at base ; the second concave at base and much 

 swollen beneath between base of first and end of cell. 



III. Sadarga. ^
