Dryophanta macroptera.—On the young twigs of the 
Turkish oak, Quercus Cerris, this species produces swellings, 
which vary considerably in size and form; sometimes they 
are small and of an elongate-oval form, and, like cocoons, 
contain a larva, and in this case they produce merely a slight 
incrassation of the twig. Sometimes the cells are densely 
crowded, and arranged in a radiating fashion under the rind, 
causing a manifest thickening of the twig. The perfect insect 
emerges in October of the same year.—G. L. Mayr. 
Dryophanta macroptera has four inquilines; one of them 
occurs also in the two preceding galls. (1) Synergus flavipes, 
Hart.: June; second year. (2)S. variabilis, Mayr: May toJuly; 
second year. (3) S. rotundiventris, Mayr: May ; second year. 
(4) Ceroptres Cerri, Mayr: May; second year.—F. Walker.
