The article consists of an historical introduction (chap, i.) ; the 
descriptions of species already referred to (chap, ii.); a chapter on 
the formation of galls (chap, iii.) ; and another giving full anatomical 
details respecting the structure of the ovipositor, and the process of 
oviposition (chap. iv.). The latter is summed up as follows : (1.) The 
tunnel is bored, first by passing the ovipositor under the scaly cover- 
ing at the base, and then driving it to the centre of the axis of the 
bud. (2.) The egg passes from the ovary to the base of the ovipositor ; 
its stalk is grasped between the bristles of the latter, and the egg is 
pushed down to the ovipositor. ( 3.) The tip of the ovipositor is with- 
drawn from the channel, into which the egg passes, when it is pushed 
forward by the ovipositor, till it reaches the extremity. Chapters v. & 
vi. contain a comparison of the alternate generations of the Cynipidce 
according to their structure ; a discussion on the relations which the 
sexual and asexual forms bear to each other, and general concluding 
remarks. The first two plates are coloured, and represent galls and 
gallflies ; the third represents details of the ovipositor and eggs.
