in spite of this, I have described A. circnlans as a new 
species, it is because the flies differ considerably from one 
another, and A. burgundus appears a month 
later. Dr. Giraud informed me that he also 
had met with the species last described, and 
thought itnew. He thinks that each gall of 
A. burgundus is formed on an anther, and 
the union of several galls in an undeveloped 
flower-bud would produce such an impres- 
sion. It is certain that the galls of A. cir- 
culans are generally developed on leaf-buds, 
and further investigations will show whether 
the galls of A. circulans are on/y to be found , 
on leaf-buds, and those of A. burgundus 
only on flower-buds. The figure of the gall 
of A. burgundus is from typical specimens. ,

In the ‘Entomologische Zeitung’ (Stettin), BURGUNDUs (of the 
xxxi. 396, Von Schlechtendal, in his paper ae i = 
on gall-flies, describes the gall of another 3 
and new species as the Andricus burgundus, Gir. This is 
another Turkey oak species, and has not occurred in Britain.

41. Spathegaster Giraudi, Tschek.—This small oviform 
gall, varying in length from 2°7 to 4°5 millimetres, is deve- 
loped in the early spring from -the small 
axillar buds (which are scarcely larger than 
a pin’s head) of the weakest, one-year old, 
shoots of Quercus pubescens. When recent 
it is green, more or less reddish, and gene- 
rally thickly covered with soft, red, por- 
rected hairs. It only consists of a thin, 
moderately soft shell, which forms the larva- * 
cell; the small bud-scales are situated at the 
base of the gall. The gall-fly appears in the 
first fortnight in May. ‘This year, the spring 
being late, | did not obtain the fly till the Gaur or 
middle of May, from fresh galls kindly sent — 5. Graupr.

rather commonly near Piesting (Austria), by Tschek (1869,
