THE ENTOMOLOGIST. 



pierced b}- the perfect insect in the ensuing spring. How- 

 ever, I am not quite certain about this matter. — G. L. May?: 

 Synergus melanopus, S. palUcornis, and Ceroptres arator, 

 are mentioned by Dr. Mayr as the inquilines of this gall ; 

 they all appear in May, the second year. — Francis IValker. 

 17. Ci/nips ilncloria. — This species 

 Fig. 17. furnishes the Levantine ink-galls of com- 



merce, but the galls we receive from 

 Turkey differ in size and colour from 

 those which grow in Central Europe. 

 The gall in this neighbourhood is very 

 much like small specimens of the last- 

 described gall. It is from ten to fifteen 

 niillemelres in diameter, of a reddish brown 

 colour, bare, and beset with subglobular, 

 wart-like excrescences. It consists of a 

 dense reddish brown reticulation, and 

 grows together with the inner gall, which 

 is woody, of a light yellowish colour, and 

 well defined. It grows out of the axils of 

 a shrubby form of Quercus subsessiliflora 

 Cynips TiNCToniA ^"^ Q- pu^escens. In the latter end of 

 and in section). autumn it is no longer firmly attached to 

 the branch ; therefore a great number are 

 detached by the winter winds; nevertheless, some remain 

 on the twigs until the spring. The perfect insect emerges in 

 the spring. — G. L. Mayr. 



Six species of Synergus are enumerated by Dr. Mayr as 

 the associates of Cynips tinctoria, S. melanopus, Reinhardti, 

 pallidipennis, Hayneanus, palUcornis, and vulgaris. The 

 three following appear in the second year: — S. Reinhardti in 

 June, S. palUcornis in May, S. vulgaris in March. Dr. 

 Mayr mentions Callimome regius as the parasite of Cynips 

 tinctoria. — Francis Walker. 



Sphin.v Convolvidi at Maidenhead. — It may interest some 

 of your readers to learn that I took a fine male S. Convolvuli, 

 on the morning of the 9th of September, at Maidenhead. I 

 have never heard of one being caught here before. — JV. 

 Harper ; Norfolk Road, Maidenhead, Berks, Sept. 12, 1874.
