Although the three an- terior hindwing ocelli occur in cells that, in terms of se- rial homology, correspond to the forewing cells that al- ways have border ocelli, tinlike the forewing, on the hindwing the ocelli are located far from the margin (Figs. 3,4). 5. ANDROCONIAL SYSTEM Alar androconial organs. According to MILLER (1968: 34), "there is a patch of mealy scales on the upper end of the cell along crossvein rs-ml, and a long hair tuft lies along ; As long ago and more accurately pointed out by MÜLLER (1877), the males of Bia possess a "tuft of long pale leather-brown hairs near the inner margin of the hind-wings, which can be erected or de- pressed at will, and when at rest, are enclosed in a long pocket, and also by a patch with long black silky hair.
