this species. I coiild then remember seeing a single plant of the "Thale- 

 cress," Sisymbrium thalianum, J. Gay, and striking it with the net, the only other 

 Cx'uciferous plant seen near at hand being water-cress, growing on the margin 

 of the river at the foot of this bank, but this plant I had not tonohod. Upon 

 going to the bank the next morning I examined the plant of " Thale-cress " and 

 found four more C. atomus on the flowers, and a careful search along the bank 

 produced another small plant of " Thale-cress " and another pair of the 

 Ceuthorrhynchus. As the season for the plant was over, and these only two 

 belated examples, I was unable to again verify my captures, but write this note 

 in hopes that it will be searched for by other collectors earlier in the season 

 when the plant is in full flower. — H. Britten, Prospect House, Salkeld Dykes,

Tychius pohjlineatus, Germ., at Streatley, Berks. — On July 19th I took a 

 single example of this rare and handsome Tychius on the chalk downs near 

 Streatley by sweeping mixed Leguminovis flowers, Lotus corniculatus, Anthyllis 

 vulneraria and a species of Medicago predominating, but I am under the 

 impression that the weevil came off the first-named plant. Mr. N. H. Joy, 

 I believe, took a worn example of the species some years ago on the same range 

 of chalk-hills. My specimen is in fine fresh condition, but unfortunately both 

 the antenuEB are mutilated. — James J. Walker, Oxford : August 15th, 1910. 



Ca'pture of Trichonyx sulcicollis, Reich., and T. mcirkeli, Aube. — In June last 

 I was fortunate enough to take a small series of Trichonyx sulcicollis, Reich., in 

 the damp rotten wood and fungoid growth of a moribund beech tree in the 

 New Forest, near Brockenhurst ; and since my departure, further specimens 

 have been taken in the same tree by Mr. Donisthorpe and Dr. Sharp. As far as 

 I coiild ascertain at the time the tree was entirely free from ants of any kind. 

 T. mdrkeli, Aube, has been found rarely (and also imaccompanied by ants), by 

 Mr. J. Collins, in a sand-pit near Cumnor, Berks, at the end of Jime ; and 

 thanks to his kind indication of the locality, Mr. Donisthorpe and I have had 

 the pleasure of taking this interesting Pselaphid for the first time. — Id. :

New localities for Ptinus tectus, Boield. — This comparatively recent intro- 

 duction to oiir British list of Coleoptera is evidently on the increase in this 

 country, and indeed seems likely ere long to become one of the commonest 

 species of its genus with us. On August 3rd I found it in plenty among refuse 

 in a granary at Faversham Creek, Kent, and a few days later again came on it 

 in large niunbers in the " sack-heap " of the Sheppey Glue and Chemical "Works 

 at Queenborough. The size and fine development of the specimens from the 

 latter locality tend to show that grain is by no means a necessity for Ptinus 

 tectus, as I could find nothing whatever of a farinaceous nature among the very 

 miscellaneous contents of the condemned sacks.— Id. : August 15th, 1910.
