50. Dryophanta longiventris, 
Hart.—Up to this time I have 
only found this gall on the com- 
mon oak. It agrees with the 
last-described species in size, 
shape, substance, surface, at- 
tachment, and inner structure, 
but differs from it in colour, 
The gall of this species is red, 
and has rather broad, often a 
little raised (rarely projecting 
like papille), mostly circular, 
yellow stripes. Another small 
distinction is that it is flattened 
at the base. Should the gall 
be gathered in an unripe state 
it shrivels up between the rings, 
so that the rugose surface ex- 
hibits red furrows, with yellow 
tortuous borders; whilst the galls 
of D. folii would, in such cases, 
: exhibit irregular tubercles. The 
a pillar to Da, gall appears at the beginning of 
(and in section).  (andinsection). June. Herr von Schlechtendal 
states the flight time of the gall-fly as varying from the beginning 
of August to the end of October. I found great numbers of 
this species in the Leithagebirge mountains, but only bred a 
single fly in the winter, and extracted a living specimen from 
one of the galls in November.—G. L. Mayr.
