Art. XV. — Observations on the British Cynipites. 

 By Francis Walker. 



The Cynipites, like other tribes of insects, have some cha- 

 racters which are nearly constant, and some which vary much. 

 Among the former, are the head, the joints of the antennae, 

 and the nervures of the wings ; among the latter, the habits and 

 economy, the thorax, and, still more, the abdomen. The 

 greatest variation is between Anacharis and Ibalia. 



The whole tribe were formerly called gall-flies, and it was 

 supposed that they laid their eggs in plants, which their grubs 

 caused to swell around them, and to form excrescences, or galls. 

 It may be inferred, from the recent discoveries of Entomo- 

 logists, that only a very small portion of the British species 

 live thus ; the rest are parasitic upon other insects. The 

 external characters are sometimes very similar, although the 

 economy is different; e.g. the species of the 10th and 23d groups 

 in the following arrangement, move slowly, counterfeit death 

 when touched, have the abdomen compressed, and the fore- 

 wings very long and broad. Cynips aptera lives under ground, 

 forms galls on roots, and is infested by Callimome roboris ;
