ment. Then comes a small slightly flattened filament, with 
tip somewhat broader than the insertion. 
Arising from a separate point of insertion in the outer 
lobe, and most dorsal in position, is a heavily sclerotized 
appendage, nearly as long as the mesial hooked filament. 
This appendage is bent upwards from the point of insertion 
to about one-third its length, then downwards to two-thirds j

its length, and then is produced in line with its insertion. 
The tip of this appendage is flattened dorso-ventrally, thick, 
and bluntly pointed. A thin membranous expansion arises 
from a point near the insertion of this appendage, and is 
attached all along the dorsal edge, to a point about two- 
thirds the length of the appendage. This flattened mem- 
brane is somewhat incurved. The outer border of the mem- 
brane is sinuous, the edge arising abruptly from the point 
of attachment at the proximal end of the appendage, to its 
greatest elevation about one-third of the length, then curv-
