THE ENTOMOLOGIST. 93 



Goureaii's Observations on Parasitism. — 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 sciitel- 

 laris, Nees (male = miiticiis, 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 larvae 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 (Erythraeus) pomariorum ; the grub of the latter 

 lives in the nest, and devours successively larvae and pupaj. 

 He also mentions one specimen of Eulophus Cervus, which 

 he does not describe. — Francis Walker. 



AcuntJtocinus j^dilis. — Acanthocinus -^Edilis is the name 

 of the beetle sent by Mr. Sclater, of Castle Eden. I am 

 obliged for it. — Edtvard Netvnian. 



ApJiilolhrix Sieboldii in England. — I 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. 1 also enclose the three images 

 that I reared from theu). 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 Hgw 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 I 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 

 Aphilolhrix, T 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 

 Aphilolhrix Sieboldii, and Mr. Moncreafl's communication 

 is particularly interesting as showing, first, that the range of
