c? ?. Thorax yelhiw iibove in both sexes, except a black, ill-detined, transverse 

 band anteriorly on mesonotum ; sometimes the centre of thora.x more or less black. 

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

 specimen figured by Boisdnval as inferimlis is what Butler named tinifonnis. 

 There occur individuals in whicli the yellow scaling is vestigial, others in 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 tijiped 

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

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

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

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

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