In each of the finger-like processes, the larva (pl. XXV, fig. 7) 
develops into that of the 2nd stage (pl. XXV, fig. 8), and the latter 
becomes later a wingless viviparous female (pl. XXV, fig. 9). This 
viviparous female reproduces parthenogenetically the young within 
the finger-like processes (pl. XXV, fig. 10 and pl. XXVI, fig. 11). 
In the last part of June, the finger-like processes grow in size, 
and form a nearly spindle-shaped sac. The central hollow disc 
becomes shallow, and the sacs are directed outwards, looking like 
a fully opened flower. In this case, a single gall is about 2 cm. in 
diameter, and of a light greenish color (pl. XXVI, fig. 17) although 
some (pl. XXVI, fig. 18) are much larger with a diameter of about 
4 cm. Each of the sacs lying around the central disc contains 
usually a single wingless viviparous female (pl. XXV. fig. 9) 
together with the numerous larva laid by it (pl. XXV, fig. 10 and 
Dl OVA sites 01): | 
In the middle of July, the galls attain their full growth, the dia- 
meter reaching about 6 cm. (pl. XXVI, fig. 19). Each spindle- 
shaped sac now assumes an elongated oval form and is of a light 
greenish yellow color. The larva contained in a single sac 
(pl: XV, fie. To ¡and pl: XXVI, figs"11) develop: into pupa 
(pl. XXVI, fig. 12) and when the winged Insects are ready to 
emerge, the free rounded end of the sac opens, and the Insects 
fly out in succession. These are all females and produce the young 
parthenogenetically (pl. XXVI, fig. 14) either in- or outside the 
galls. These larve after moulting once pass into the 2nd stage 
(pl. XXVI, fig. 15).
