small galls growing out of the axillary buds on stubs of the 

 Turliey oak ; the producers of these belong to a new species. 

 These galls are of an elongale-oviforni shape, 

 similar to small ant-pupse, about 2 to 5 milli- 

 metres long ; from one to eight occur in a 

 bud, and are so surrounded by the interior 

 broad and short bud-scales, that only their 

 i^P^ upper part is visible. When the air is humid, 

 " ' the long linear outside scales stand out in 

 such a manner that the gall is easily seen, but 

 when the weather is dry they close over the 

 galls in such a manner that it is difficult to 

 see them. The galls are naked, of either a 

 brownish yellow, a dirty reddish brown, or a 

 beautiful light red colour, and show, when 

 examined through a strong magnifying-glass, 

 oval or elliptical cells. The walls of the 

 gall are very thin, and enclose the cavity in 

 which the gall-maker lives. If a large number 

 of galls occur in one bud, it sometimes 

 happens that one gall is in the centre, while 

 the others are arranged round it in a circle ; 

 when there are only four they resemble the 

 seeds of one of the Labiatai : the galls are 

 frequently so compressed that they are flattened at the points 

 of contact. Galls collected in February and kept in a hot 

 room, produced some males at the beginning of March, while 

 the females did not appear till eight or ten days later; from 

 those collected on March 21st the flies emerged in April, 

 and of those collected on April 15th many were already 

 pierced ; but from those that were entire the flies emerged 

 in the course of a few days. No Andricus appeared in May 

 — only a few Ceroptres and Pteromalidas. 1 have only met 

 with a few specimens this year. — G. L. Mayr. 



In a note Dr. Mayr gives a description of the imago. The 

 Ceroptres referred to is C. Cerri, Mayr. — E. A. Filch,
