c? ?. Thorax yellow above in both sexes, exrejit a black, ill-deliiied, transverse 

 band anteriorly on mesonotnm ; sometimes the centre of thorax more or less black. 

 The yellow band of abdomen occasionally reduced, seldom altogether absent. The 

 sjiecimen figured by Boisduval as infenidUs is what Butler named uni/ormis. 

 There occur individuals in which the yellow scaling is vestigial, others iu which it 

 is more apparent ; a Sikhim specimen in the Tring Museum has yellow hair-scales 

 on the upperside of several segments, and the posterior side-tufts are also ti]>ped 

 with yellow, but there is no band. All these individuals agree iu the structure of the 

 sexual armature, and are doubtless individual forms of the same species. An example 

 from Borneo in the Paris Museum differs remarkably in the bases of the wings 

 being white below, and in other characters; it represents perhaps a subspecies. For 

 convenience we treat the three principal types of colour as individual forms.
