punctured striae moderately strong, interstices flat, rather shining, almost smooth ; 

 anterior femora armed with a long sharp triangular tooth ; anterior tibise very 

 strongly sinuate on their inner margin, the margin being almost angled in the centre. 



Length, 2 — 2j mm. 

 By beating hedges (probably on CratcBgus), Eepton, Burton-on- 

 Trent, and Bircham Newton, Norfolk ; I believe tbat the species is by 

 no means uncommon, and will be found in most collections.

HYMENOPTEEOLOGICAL NOTES. 



BY P. CAMERON, F.E.S. 



I.— NOTES ON BEITISH CYNIPIDJE. 



SnpJiolytiis connatus, Hartig, Germ. Zeit., ii, 198. — This species 

 is British ; I have reared it from the galls of Andricus noduli in 

 Clydesdale. Sapholytus merely differs from Synergus in having an 

 open radial cellule. 



Xestophanes. — We have two species of this genus in Britain — 

 potentillcB, Lin., = splendens, Htg., = alhreviatus, Thoms., Opusc. 

 Ent., 1877, 805, and brevitnrsis, Thoms., I. c, = tormentillce, Schlecb- 

 tendal, Ent. Nacht., 1880, 176. The latter species is readily separated 

 from potentilJce by the third antennal joint being perceptibly longer 

 than the fourth, by the parapsidal furrows being complete, and by the 

 fourth joint of the hinder tarsi being hardly longer than broad. Po- 

 tentillcs ioYxn^ gaW^ on Potentilla reptans ; hrevitarsis on Potentilla 

 tormentilla. 



Aidnx graminis, Cam. — 1 ca,T\T\ot distinguish this species by any 

 characters, structural or in coloration, from A. hierncii, and am in- 

 clined to think the two are identical, notwithstanding that they are 

 found on such different plants. This conclusion seems the more likely 

 from A. hieracit having been bred from galls on Linaria vulgaris and 

 Cytisus capitatus ; cf. Mayr, Cynip. Grallen, p. 9. 



Aulax m«??or, Htg. — I should say that this species is only a variety 

 of A. papaveris. According to Hartig and Mayr, it differs from 

 papaveris in the antennae being " brown," often yellowish or reddish 

 at the base, the scutellum without a furrow, and the abdomen in ^ 

 more or less yellowish or castaneous-brown beneath. I find, however 

 so much variation in all these points, as also in size, among specimens 

 reared from poppy capsules collected in the same field and at the same 

 time, that I cannot quite look upon minor as a good species.
