with A, inflator. Dr. Giraud tells me in a letter that he takes 
it fora modified form of the gall of Andricus curvator, A 
specimen which Professor Schenck gave me consists of a 
swelling, almost egg-shaped, of about 8 millimetres, by 5:5, 
full of blisters, thin-walled, the surface of which is uneven, 
covered with leaf-like scales, on one side leaving folds, the 
margin of which exhibits indistinct traces of leaves; at the 
bottom of the large cavity lies an oviform inner gall. This 
swelling is situated in the upper angle between the twig and 
the lateral bud; the latter, however, does not grow on the 
twig itself, but on a very short stumpy lateral. 
Note 1.—On May 19th of this year (1870?) I found two 
swollen galls on Q. sessiliflora which seemed to belong to the 
galls of C. axillaris, although when fresh they differed in 
appearance. At the beginning of June, I opened the 
larger of the two, the cavity in which resembled the 
gall of A. curvator, which species I extracted from it.—

38a. Andricus curvalor var. axillaris —From 
Mayr’s note, and a subsequent one under cur- 
vator, it will be seen that figure 38a is referable 
to Andricus curvator var. axillaris, and not to 
A. inflator. 
This gall is, I believe, tolerably well distributed 
in Britain: it has occurred, but never commonly, 
almost everywhere I have collected, and has been 
recorded from Scotland (Ballater) by Mr. Trail. 
Sapholytus connatus, H., is its inquiline, and 
Megastigmus dorsalis a parasite, both occurring, 
like the gall-maker, in the early summer. Ratze- A- cuRvaTor 
burg says, in his ‘Die Ichneumonen’ (ii. 151), yy tcprs. 
“T obtained one female from Herr Hartig, which 
he had determined as Siphouura variolosa, Nees. He had 
bred his specimens from Cynips disticha and Andricus 
noduli and inflator.” §. variolosa, Nees, is probably a 
synonym of Ormyrus punctiger, Westw., a species which 
occurs in several galls. In addition to M. dorsalis I have 
bred Syntomaspis caudata, Nees., Pteromalus sp.? and 
Psocus bipunctatus from these galls.—H. A. Fitch. 
39. Andricus circulans, Mayr.—In February and March 
of last year (1869) I found, in the neighbourhood of Vienna,
