who was somewhat doubtful as to its being the producer of

the leaves of young oaks. It is a green, 

 sappy, smooth ball, of from five to seven 

 millimetres in diameter, and attached to the 

 leaf in one spot only. In section it exhibits 

 a central larva-cell, surrounded by a thin Biokhiza synaspis 

 inner gall bordering the sappy reticulation. (fi"^i ^ section). 

 In June the gall (alls, and assumes a red 

 colour ; and towards the end of the month, or in July, it is 

 pierced by the wingless gall-fly. The specimen figured 1 

 obtained many years ago from Dr. Giraud (never having 

 found the gall myself). It is of a brownish yellow colour, 

 covered with numerous red spots. — G. L. Maijr. 



This insect belongs to the Hartigian genus Apophyllus, 

 which is separated from Biorhiza, Westw., through having 

 one less joint in the antenna than that genus. Harlig him- 

 self included this species and Biorhiza aptera both in 

 Apophyllus. Since the publication of his ' Mitteleurop. 

 Eichengallen,' &c., Dr. Mayr has met with the galls of this 

 species in some numbers on Quercus sessiliflora, and more 

 rarely on Q. pubescens in September, thus differing from 

 Hartig's time of appearance, who says " the gall falls in 

 June." He also bred from them at the beginning of October 

 several specimens of Synergus albipes, H., and S. physo- 

 ceras, iy. ; the latter occurs in no other gall but this, Hartig's 

 specimens, received from Kollar, being bred from " small 

 round galls on the leaves of Quercus pubescens." This gall 

 has not been recorded as British, but it is doubtful whether 

 it does not occur here. — E. A. Fitch.
