and Tschek succeeded in breeding some flies as early as 

 February and March, the greater number, however, not 

 appearing before the following October and November. — 

 G. L. Mayr. 



In a subsequent note Dr. Mayr has the following (second 

 half, p. 68) :—" On the 2nd October, 1870, I found, near 

 Gulenstein, in North Austria, the still green galls of this 

 species, in great numbers, on the ground under high trees of 

 Quercus sessiliflora, some of which were surrounded by the 

 bud-scales. From hundreds of these galls a single gall-fly 

 emerged on the 23rd March of this year (1871), so that I may 

 expect a great number in the autumn." Again, in the 

 ' Verhandlungen' for 1872 (vol. xxii.), he tells us that "from 

 the Gutenstein galls of this species I bred at the end of 

 February, and particularly in March (1872), a great number 

 of the gall-maker. On the 8th October, 1871, I also found 

 in an oak wood, near Vienna, some galls under large trees of 

 Quercus sessiliflora." Synergus raelanopus and S. vulgaris 

 were bred from the galls by Dr. Mayr. Curiously, the gall 

 from which the original description was taken by Giraud was 

 found under a tree by a very young person at Wiener- 

 Neustadt.— ^. A. Fitch.
