114 NYMPH ALID^. SATYRIN^E. MYCALESIS. 



Fifth Group. — Calysisme : " Wings short, broad. Foreioiug with the costa arched at base, 

 apex acute in male, less so in female, exterior margin oblique and curved, posterior angle acute ; 

 costal, median, and submedian nervures swollen at the base ; second subcostal branch emitted 

 immediately before end of the cell ; cell broad ; disco-cellulars very concave, radials from 

 two angles in upper near subcostal. Hindiving oyzS. ; costa arched at base ; exterior margin 

 convex, dentate ; first subcostal branch emitted and swollen before end of the cell ; disco- 

 cellulars slightly concave, radial from their middle ; two upper median branches from end of 

 the cell. Male with a tuft of long hairs at base of subcostal covering a glandular patch of 

 scales. Body slender ; palpi porrect, slender, finely pilose beneath ; legs slender. Antennce 

 slender at tip. £jw hairy." {Moore, Trans. Ent. Soc. Lond., 1880, p. 161.) 



This group comprises about twenty supposed species, some of which are very closely 

 allied if not inseparable ; fourteen have been described from India, but of these we can only 

 admit four as clearly distinct ; and the remainder are found in the Malayan region extending to 

 China on the East and to Australia. There are two distinct types of colouration and markings — 

 first the '* mineus " type, in which the basal area of the underside is uniformly coloured, 

 many of the ocelli are always prominent, and they are enclosed in groups by fine 

 sinuous lines ; second the '^perseus''' type, in which the basal area of the underside is 

 always more or less speckled or striated ; the ocelli are usually minute, often replaced by 

 white or black dots, and sometimes quite obsolete ; always well separated in all cases ; 

 the transverse band too is less distinct, sometimes barely traceable. Both types present 

 variations in the outline of the forewing, some species having the apex angled, and others 

 having it rounded, with the outer margin more convex.

The first species of this group, M. blasius, is chiefly to be distinguished from M. mineus, 



which follows, by its usually smaller size and by its having the ocellus on the upperside of the 



forewing very small, rudimentary, or altogether wanting ; the median fascia on the underside 



is also narrower and usually tinged with purplish. The ocellation of the forewing on the
