GYNZCIA. 
Gynecia, Doubleday, Gen. Diurn. Lep. p. 248 (1850) (ex Boisduval MS.). 
A single species of wide range throughout Tropical America constitutes this genus. 
In some respects this insect has a general appearance not unlike that of Callizona: but 
the resemblance is superficial, though the habits of the two coincide in that they settle 
on trees in the same way with the wings perpendicular. 
The subcostal nervure of the primaries in Gynecia emits two branches before the 
end of the cell; the upper discocellular is very short, the middle nearly straight but 
slightly curved where it meets the lower radial. There is a rudimentary lower disco- 
cellular which meets the median nervure a little beyond the origin of the first branch. 
The front legs of the male have a stout coxa a little >+4 femur-+ trochanter; tibia 
slightly swollen towards its distal end=femur ; tarsus single-jointed==2 tibia *. 
Hyes smooth. Antenne with 40 to 42 joints, whereof the terminal 10 form a rather 
abrupt club. Palpi slightly hairy, terminal joint >4 middle joint, which is slender and 
of nearly uniform width. The male secondary sexual organs have a pointed tegumen ; 
the harpagones are broad lobes, hairy at the extremity and on the ventral surface ; 
there is a decurved dentate process at the distal end and a curved hook on the inner 
surface of each harpago. The penis is not straight, but is curved upwards in the 
middle. 
In the structure of these parts Gynecia differs widely from Callizona.
