326 Notice of Dr. Mayr's Essay 



and assigns the second class to the Torymidce; in the second 

 part the Torymidm take the precedence, and the plants are 

 transferred to the second class. Lochites and Syntomaspis 

 seem to have been needlessly separated from Callimome, and 

 may be again combined with it. Of the three species 

 which are included in Diomorus, the first and second differ 

 much from the third and may form, one genus with Crypto- 

 priskis caliginosus. The third species, D. armatvs, is the 

 type of the genus Diomorus, which was perhaps unadvis- 

 ably separated by me from Callimome, the dentate hind 

 femora being the only character which distinguishes it. 

 The genus Podagi'ion, as I think, should continue in this 

 family, but Dr. Mayr excludes it. I formerly thought that 

 the comparative length of the oviduct was a good specific 

 character in the genus Callimorne, but Dr. Mayr has a con- 

 trary opinion, and he is most qualified to judge, having been 

 enabled to examine numerous specimens of the family from 

 many kinds of galls. It might be supposed that the length 

 of the oviduct would correspond with the size of the gall 

 in which the Callivioine seeks to find a maintenance for its 

 offspring, but Dr. Mayr observes that the long oviduct of 

 Syntomaspis caudata is inserted both into the oak apple and 

 into the oak spangle. Oak apples are the chief resort of 

 Callimome ; at the end of June and in the beginning of 

 July thousands of Andricus terminalis may be seen coming 

 out of these galls, and they are soon followed by hundreds 

 of Synergus fcocialis and of Callimome anratus.
