genus :— 
Scleroderma contracta. 
Westw., Trans. Ent. Soc., 11, 169. Plate XV., fig. 11. 
Hab. Carolina. In Mus. Berlin. 
This female insect is nearly a third of an inch long, 
its large size dissociating it from the legitimate Sclero- 
derme, its general form, especially of the thorax, and its 
tridentate mandibles (op. cit., Pl. XV., f. 11a), removing 
it to the Mpyrides, especially near Pristocera depressa. 
(See Plate VIL., fig. 6.) Possibly the female of Pristocera 
atra, Klug. 
Scleroderma modesta. 
Smith, Journ. Proc. Linn. Soe., vol. vii., p. 27.

Belongs to the new genus Apenesia. (See below.)
