GYNjECIA. 249 



Anterior Legs of the male with the tibia and tarsus fringed on eacli side with long hairs. Femur 

 nearly cylindric, a little stouter beyond the middle, not quite so long as the tibia. Tibia 

 cylindric, slightly curved, very obliquely truncate at the apex. Tarsus scarcely two thirds the 

 length of the tibia, subcylindric, tapering gradually towards the apex, which is pointed ; the 

 base obliquely truncate. Anterior Legs of the female rather slender. Femur not quite so long 

 as the tibia, slightly stoutest near the base. Tibia subcylindric, a little curved, narrowed 

 towards the base, truncate at the apex. Tarsus about three fourths the length of the tibia. 

 First joint nearly twice as long as the rest combined, subcylindric, unarmed ; second joint equal 

 to the third and fourth combined ; these three joints armed at the apex with a spine on each 

 side, the spines of the fourth joint longest, projecting beyond the end of the fifth joint ; fifth 

 joint short, very obliquely truncate at the apex, its upper surface not more than half the length 

 of the lower, furnished at the side with a tuft of seta?. 



Middle and Posterior Legs rather large, the femora of the former longer than the tibia?, those of the 

 latter equal to them in length. Tibia? spiny within ; the spines somewhat in two internodateral 

 series, especially those of the posterior tibia?, where they are also rather more numerous ; spurs 

 short. Tarsi of the middle pair equal in length to the tibia?, those of the posterior pair rather 

 longer than them ; all the joints, except the fifth, spring laterally below; the spines of the lower 

 surface somewhat in two series. First joint longer than the rest combined ; second joint scarcely 

 more than one fifth the length of the first ; third joint about two thirds the length of the second ; 

 fourth joint half the length of the second; fifth joint longer than the second, a little produced 

 above at the apex, with two scries of spines below, but without any lateral ones. Claws curved, 

 grooved below. Paronychia with the outer lacinia pointed, as long as the claw ; the inner much 

 shorter, strap-shaped. Pulvillus small, shorter than the claws. 

 Abdomen about two thirds the length of the inner margin of the wing. 



Larva nearly cylindric, rather smaller towards the head, which is armed with two long 

 verticillate spines ; the prothoracic segment armed with two simple spines, all the other 

 segments with several branching ones. 

 Pupa elongate, tuberculate; the head deeply bifid. 



Gynsecia may be known from the preceding genus by its more robust structure, the ditferent form of its wings, 

 especially of the posterior pair, and the different proportions of the joints of the palpi. 



Like the preceding genus, it consists of but one species, which is common throughout most of the tropical parts of 

 America. The lower surface of its wings bears much resemblance in its markings to those of Callizona Acesta, being 

 crossed by numerous brown bands on a pale ground ; the short tail has a black ocellus pupiled with blue. 



The Larva, figured by Stoll, is subcylindric, smaller towards the head, which bears two long verticillate spines, 

 and, according to Stoll's text, a simple one between them ; but from the figure it is quite clear that this spine is one of 

 a pair on the prothoracic segment. All the other segments have several branching spines. The Larva of the male is 

 fuscous, with a row of greenish spots down the side. The spines of the head, the three thoracic and the last abdominal 

 segments, are white, the rest of a dull yellow, inclining to red. The female has all the spines of this latter colour, and 

 has the back crossed by eight greenish yellow bands. Its food is the cassava. 



The Pupa is elongate, with the head bifid, and with three pairs of tubercles on the back of the abdominal segments.
