SalOnOodse. 2... You are, no doubt, aware that among our sub-apterons species 
none but females are found. Is this the case among European species? If so, 
“is not the presumption strong, that they are dimorphic forms of winged bisexual 
“species ? I do not despair of yet being able to settle this question, for a very 
“large proportion of North American species yet described are found more or less 
“abundantly on the twelve or fourteen species of oak that grow in this vicinity.” 
The questions raised by my correspondent apply to some extent equally well 
to the British Cynipide. 
By far the greater part of the latter have been described by the Rev. T. A. 
Marshall, in the pages of this Journal, yet much remains to be done concerning 
the history and appearance of successive broods of even our commonest species ; 
and it is to be desired that some observer, living in the country and with plenty 
of leisure at his command, would take the trouble of carrying out a series of closely 
watched experiments on a large scale, and extending over various seasons, as such 
continued experiments can alone give us “ more light”? about dimorphism, and the 
role the seldom occurring male element playsin the propagation of hymenopterous 
gall-flies—AtBert Mutier, South Norwood, 8.E., May, 1870. 
On the occurrence of Andricus curvator, Hartig, in Britain.—To my knowledge, 
the credit of first breeding British specimens of this Andricus is due to my friend 
Mr. H. W. Kidd, of Godalming, who sent me specimens of it a year ago. Shortly 
afterwards I bred it myself from what Mr. Kidd terms the “ kidney-shaped gall” of 
the oakleaf. This gall consists of a thick swelling of any one of the ribs of the 
oakleaf, projecting above and beneath and forming a large cell, to the interior of 
which one or two reniform, first whitish and aiterwards chestnut-brown, thin small 
papery cases are found loosely attached by one end. In this reniform case the 
larva is hatched and passes its whole metamorphosis, the imago making its escape 
by piercing first the case and subsequently the outer green shell of the gall.

antennis fuscis, basi pallidioribus ; pedibus testaceis, cowis, femoribus posticis latere 
interiore plus minus nigris.—Long. lin. 1.3.9. 
I may add that some of my specimens have had the benefit of bemg examined 
by the Rev. T. A. Marshall. —Ib. 
Synonymic notes on some species of Cecidomyia.—I think it best to bring for- 
ward the following synonymical notes separately, so as not to have to introduce the 
matter into the projected list of British galls. 
Cecidomyia veronice, Bremi. 
Bremi, Beitriige, etc., 1847, p. 49, 6. 
Loew, Die Gallmucken, Pr. d. Pos. Gymn., 1850, p. 37, 41. 
Winnertz, Beitrag, etc., Linnea Ent., 1853, p. 237, 24. 
=Cec. chamedrys, Inchbald. Ent. W. Intelligencer, 1860, Vol. 8, p. 196. 
The larvee form the tufts of woolly leaves on Veronica chameedrys. 
Cecidomyia millefolii, Loew. 
Loew, ut swpra, 1850, No. 46. 
=Cec. achillew, Inchbald, ut supra, 1860, Vol. 8, p. 195. 
The larve inhabit calyx-shaped galls in the axils of the leaves of Achillea 
maillefoliwm.
