emitted before end of tlie cell; discocellulars long, slightly concave, radial from their 
middle; two upper median branches from end of the cell. 
Male with a tuft of long hairs on upperside of the hindwing , radiating from 
below the base of the subcostal vein, and overlapping a glandular patch of scales 
situated below the first subcostal branch, this branch being also slightly swollen 
beneath, all encompassed by the broad costal nacreous area. On the underside of 
th e forewing, surrounded by the posterior nacreous area, is a glandular patch of 
scales situated upon the middle of the submedian vein.

Seasonal Forms and Similarity oe the Species. —The species of Calysisme, as 
has been proved by the breeding of G. visala and G. persons by Mr. L. de Nice villa* 
have two forms of individuals in the annual broods that occur in each species, a 
wet-season form, and a dry-season form. Both these forms had previously been 
separately named and described, and considered hitherto to be distinct species, one 
^ die other. The two forms, as hereinafter described, much resemble each other 
on the upperside of the wings, but on the underside the two forms are very dis¬ 
similar, the wet-season form being marked with a transverse pale band, and pro¬ 
minent ocelli upon the outer border; these characteristic markings being, in the dry- 
season form, only represented by a more or less defined darker line bordering the 
basal area, and the ocelli are undeveloped, or represented only as small black spots 
with a white central dot, and these spots being generally more or less obsolescent. 
The wet-season forms of the various species, however, are much alike, both 
above and below, and the dry-season forms of the various species have a similar 
resemblance, one to that of the other; consequently, this similiarity of both the upper 
and underside makes it extremely difficult to discriminate one species from another, 
and it is mainly by the aid of the position, size, and colour of the glandular
