from the margin of the cup, and bear leaves. From the 

 collected galls the gall-flies appeared in the middle of June, 

 and I found a gall as early as June 8th, which was already 

 empty : it is, therefore, very possible that the usual flight 

 time is still earlier, for the wet spring of this year retarded 

 the appearance of gall-flies generally. A. sinf/iilaris bites its 

 exit-hole through the upper apical end of the inner gall, so 

 that it is observable without separating the rudimentary 

 leaves. Soon after the emergence of the gall-fly these leaves 

 wither and become yellow, the globular gall shrivels con- 

 siderably and falls; at least it has done so in many cases, 

 according to my own observations. 1 at first took this gall 

 for a very small variety of that of Andricns ci/donice, to which 

 it bears a great resemblance, yet it is separable from that 

 species in that it is always much smaller, and because it 

 always contains but a single central inner gall. A comparison 

 of the imagos of the two species leaves no doubt but that 

 they are quite distinct. As may be seen in the figure of the 

 new species the leaf rosette is more or less unconnected with 

 the gall, still it must be placed amongst the bud-galls, for in 

 this case the axis of the bud itself becomes centred in the 

 inner gall. In anatomical structure this gall stands in nearest 

 relationship to that of Andricus injlalor, differing from 

 it that the inner gall takes up the whole of the small 

 cavity of the short cup, while in the gall of A. inflator the 

 inner gall only lies at the end of the large canal-like cavity 

 of the long cup. — G. L. Mayr. 



This recently discovered Turkey oak species is hardly 

 likely to occur in Britain. In addition to the gall-maker 

 Dr. Mayr bred Synergus thaumacera, Meyasligtiius dorsalis, 

 and Synlotiiaspis cerri, from these galls. This last new 

 species of Torytnidce has only been bred from tliis and 

 the S. polilus gall ; fourteen specimens were bred in March 

 of the second year. — E. A. FiTCH. 



96. SpatJieyasier Taschenbergi, Schl. — The typical galls 

 now before me agree both in form, size and structure with 

 the gall of Spathegaster Jlosciili, Gir. {Giraudi, Tschek.), 

 diff"ering only in pubescence. In Schlechtendal's species the 

 surface of the gall (in the dried state) is thickly covered with 

 dark violet hairs, which stand out perpendicularly : they are 

 straight, rather short, stiff' and rather pointed at the ends; 

 whilst in the gall of S. Jlosciili these (in the dried state) are 

 yellowish green, reddish, or brownish yellow in colour, more 

 or less curved, tolerably long, soft and shaggy ; the galls are
