K.— THE LEGS 



i. All black. A pair of sharp minute spines at the end of the tibia of each leg, and at the termination of each tarsus. 

 (All species.) 



ia. The measurements of the parts of the legs vary in the different species as they do in the Genera included in Vol. I. 

 lb. The ungues bifid and slightly bulbose at the base ; thickly clothed with minute spines, especially on the tibia 

 and tarsi ; the femur with a minute groove or depression. (All species). 



L. 



[The abdominal or interior margin of the male posterior wings with a fold or pouch, which conceals the androconia. 

 This fold varies in shape in the different genera, but is almost always present in the S S of the S. American 

 Ornithopterina, and always in the GeneraTrogonoptera and Pompeoptera. The margin of the wing is folded back over 

 a part of the submedian area to the submedian vein — sometimes a little beyond, and forms a sort of tube for the 

 contents ; a small portion of its basal part is sometimes again folded back in a short curve. The colour is always 

 brown or black, and as the submedian area is generally of the same colour, in a specimen newly emerged it is difficult 

 to detect the outline of this fold. The undersurface is generally lighter in colour — a nitid, rufous brown, and the 

 abdominal black or brown fringe of curved hairs is attached to the edge of the fold on this surface, so that when the 

 insect is resting, these hairs meet from the opposite wing, and serve as a hairy channel in which the subdorsum reposes.]
