APHILOTHRIX ALBOPUNCTATA. 73 
known as those of Andricus noduli, from galls under 
the bark of twigs, and petioles also, oviposit below 
ground on roots and root-fibres and produce compound 
plurilocular galls which are not only totally different 
in shape, texture and colour, but are not gregarious, 
viz. Aphilothrix radicis. 
Aphilothrix albopunctata, Schlechtendal. 
(Plate XVII.) 
Cynips majalis, Giraud; C. albopunctata, Schlch.; Andricus 
albopunctata, Mayr; Aphilothriz albopunctata, Adler, Licht., Mayr, 
Fitch, Cameron, Mosley. 
English name of gall.—‘ The Spotted Bud Gall.” 
Position of gall.—In lateral and (occasionally) terminal buds. 
Manner of growth.—‘Solitary, sessile, glabrous, glossy, longi- 
tudinally grooved. 
Colours.—Green, greenish-yellow, pale brown. 
Average dimensions of a mature specimen.— Height, 
8 mm.; breadth, 4mm.; girth, 12 mm. 
May be sought during the months of May and June. 
Growth is complete by the end of June. 
The typical condition of the gall is unilocular and unilarval. 
The larva pupates in the gall. The imago emerges during the 
following spring. 
Parasites, Nos. 39, 49, 56, 66,181. Inquilines, Nos. 130, 136. 
I have found this gall, empty, but firmly attached 
to a twig as late as September 10th (1907). 
At C in Plate XVII is shown a young gall emerg- 
ing from among the leaf scales. It is rather difficult 
to obtain a specimen in that condition. It. will be 
seen that the apex is depressed, the smooth-pointed 
projection rising from the base of the concavity. The 
depression quickly fills up and elevates the projection. 
The sides of the young gall are longitudinally 
furrowed; these also disappear as the gall grows, 
but reappear when it has attaimed maturity. 
This gall is subject to considerable variation in size, 
shape, and manner of growth. Some illustrations are
