The genitalia in the male (fig. 13) developed to the extreme of the higher 
tortricoid type : with a very broad tegumen and a complicate, often 
bilobed uncus; a large, hook-shaped gnathos; socii, not differentiated,

covered with very long bristly hairs, and with large, extremely dense

distinct, vinculum broad and strong; aedoeagus pistol-shaped; cornuti, a

'•) Often after copulation a tuft of these hairs remains between the valvae of 
the male.
