1 . Very similar to the galls on Quercus spp. made by Neuvotevus laeviuscuhis and 

 N. fumipennis, so similar that they might be galls of one of the genus. They are very 

 like Meschinelli's fungi, e.g. his Sphaerites Cavyae; but to me they do not suggest the 

 structure of a collapsed perithecium. The small raised point in the centre above (see 

 PL XX, fig. 16, 17) is much like what one finds in galls of Neuvotevus. 



2, 3. Miniatures of galls of some Cynipidae in form and slender attachment (e.g. 

 galls of Rhodites Eglanteviae on various roses, and Dvyophanta divisa on Quevcus ; in 

 thickness of wall they more resemble the latter). 



4, 5. These resemble galls formed by some mites (Eviophyidae) in numbers on 

 the upper surface of leaves (e.g. on Pvunus Padus and other trees); but somewhat similar 

 galls are formed by galbmidges also (e.g. on Nepeta Glechoma among herbs, and by 

 Oligotvophus annulipes on beech*leaves). It is difficult to be certain of the maker, therefore, 

 from the empty galls. 



6. Little cups (PL XX, figs. 2, 3) which I find it difficult to compare with any 

 gall known to m e, though probably enough they are galls."
