The rudiments of the legs may be traced in very young larvae as two 
hemispherical thickenings of the hypodermis on the under-surface of each 
of the three thoracic segments. These soon become dilferentiatod into an 
inner nucleus and an outer sheath, and in fully developed larvae the nucleus 
is conical and already presents a segmented appearance. During the pupa- 
state the legs become freed from the sheath, and grow rapidly. The wings 
appear in young larvae as two pairs of elliptical thickenings of the hypo- 
dermis on the sides of the 2nd and 3rd thoracic segments. These retract so 
as to form a case in which lie the flat heart-shaped rudiments of the
