THE ENTOMOLOGIST. 93 
Goureaws Observations on Parastitism.—A few more 
extracts from Goureau’s observations on parasitism may be 
added as an indication of what is likely to be remarked in 
England with regard to the same insects. Platygaster scutel- 
laris, Nees (male = muticus, Nees fem.), is parasitic on 
Cecidomyia Tritici; also a species of Coleocentrus lays its 
eggs outside those of the Cecidomyia, and its larva devours 
twenty larve of the latter. From the three Micro-Lepi- 
doptera, Yponomeuta Padella, Y. Malinella, and Y. Evony- 
mella, Goureau obtained Pimpla_ scanica, Ichneumon 
brunnicornis, Campoplex sordidus, Anomalon tenuicorne, 
Mesochorus splendidulus, Encyrtus fuscicollis (which comes 
by hundreds out of a single caterpillar or pupa), and 
Eurygaster (Erythreus) pomariorum; the grub of the latter 
lives in the nest, and devours successively larve and pupz. 
He also mentions one specimen of Eulophus Cervus, which 
he does not describe.—Francis Walker. 
Acanthocinus Atdilis.—Acanthocinus Aldilis is the name 
of the beetle sent by Mr. Sclater, of Castle Eden. I am 
obliged for it.—Hdward Newman. 
Aphilothriz Sieboldit in England.—1 send for your 
acceptance a few galls, which I think you will find to be one 
of the species mentioned in the ‘ Entomologist’ for March,— 
most likely A. Sieboldii. I also enclose the three imagos 
that I reared from them. Early in January, 1873, I found the 
above on the small twigs of an oak, which had been repeat- 
edly cut down, and was growing in a hedge-bank. ‘They 
were near the bank, covered with dead leaves, but not under 
the mould. The galls were quite new to me, and most of them 
were empty ; but finding a few of them unbroken, I took them 
home, corked them up in a glass, and, I think, in May the 
three imagos emerged. The empty galls may have been old 
ones, but [ at the time thought that most of the flies had 
escaped during the autumn of 1872. You will observe that 
the galls are very sparingly distributed over the branch, and 
not clustered. If they turn out to be one of the species of 
Aphilothrix, I will hunt them up, and perhaps I may find 
better specimens.—Henry Moncreaff/; High Street, Ports- 
mouth, March 2, 1874. 
[There can be no doubt that these galls are those of 
Aphilothrix Sieboldii, and Mr. Moncreaff’s communication 
is particularly interesting as showing, first, that the range of
