In such cases where the British Flora does not possess the identical 
species on which the gall occurs abroad, we have mentioned the generic 
name only as a hint to examine all the indigenous members of the genus. 
P.S.— The insertion of the genus Circcea in our last list was 
founded in error. We know of no galls on any of the species. 
On Gyrinus wneus, Steph.—In the " Entomologist's Annual " for 1869, p. 23, 
Mr. Eye has noticed Gyrinus mneus, Steph., stating that it is quoted and the' 
name adopted by Aube, in the Iconographie, &c. This is perfectly correct, but 
I think that Aube's support of Stephens' species must be shelved altogether, 
for Aube's mieus is certainly not Stephens' mneus, as a glance at the two 
descriptions renders indubitable. In short, Aube committed an error inciting 
G. ceneus, Steph., as identical with the insect he himself described under the same 
name. How Aube came to make so curious a mistake, it would be useless to 
speculate on here. G. ceneus, Aube, as noticed in the " Annual," is recognized 
generally as Dejeanii, Brulle, a species confined to the south of Europe. It remains 
then to ascertain what Stephens' ceneus is, and I fear that we shall only find that 
this is one of tho numerous cases in which Stephens' work must be considered as 
non-existent. 
Stephens, in 111. Mandib., ii, 95, quotes G?. ceneus of Leach, M.S.S., 1842. Suffrian, 
in the best paper which has yet been produced on the European Gyrini, informs us 
that he has received from Dr. Leach an example of G. ceneus, Leach, M.S., and that 
it is a specimen of G. oimcus, Sahl. Bearing iu mind this, then we refer to Stephens, 
expecting to find a corroboration of this ; but no, his descriptions indicate un- 
doubtedly (as far as they indicate anything) that Gyrinus cvneus, Stoph.=(?. marinus, 
Gyll., while G. rnarinus, Steph. == G. opacus, Sahl., and this, tliough he not only 
quotes without doubt Dr. Leach's ceneus as his own ceneus, but gives localities 
where Dr. Leach captured the species. Hence it is better not to notice Stephens' 
ceneus at all, or we shall introduce to our continental friends a discrepancy in 
Stephens' work not at all likely to increase his prestige with them.-D, Siiakp,
