It must be remarked that the characters in the table are only 

 intended to apply to the British species, which are placed in paren- 

 theses. Ammoecius is, perhaps, really an ApJwdius, as much as some 

 of the other genera which I have omitted, but its place is somewhat 

 uncertain. JD. vulneratus resembles Oxyomus sylvestris, Scop, (por- 

 catus, F.), superficially, but may be distinguished by its differently 

 shaped head, and above all by the longer of the two spurs of the 

 intermediate and posterior tibia? being much longer than the first 

 joint of the tarsi in D. vulneratus, much shorter in O. sylvestris ; the 

 form of the body is also different.

Supplementary note on Diastictus vulneratus, Sturm. — While bicycling from 

 Brandon to Elvedon in the morning of June 14th, 1902, Mr. E. A. Elliott and I 

 alighted to do a little collecting on the heath not far from Mayday Earm, about 

 three miles south of the former town. We did not search for more than five 

 minutes when a heavy shower put a stop to our efforts. These were not wasted, 

 however. Beneath small Hints lying conspicuously on the heather and grasses we 

 discovered Byrrhus murinus, Eab. (of. Ent. Mo. Mag., 1900, p. 288), Harpalus j/ici- 

 pennis, Duft, (cf. Ent. Mo. Mag., 1897, p. 9), Trachyplilueus aristatus, Gryll., a species 

 not before noticed in Suffolk, and a Coprid which was at first thought to be the rare 

 Psammohius casus, Pane., but which Mr. Newbery has been so good as to name 

 Diastictus vulneratus, Sturm. As to the locality, I can do no better than quote the 

 words of the Rev. William Kirby's " Journal of an Entomological Excursion into 

 the Isle of Ely " with Thomas Marsham, in 1797 : — "The country here affords few 

 or no objects to relieve the mind from the tedium which its bleakness and sterility 

 p»oduce in it. It may be denominated an ocean of sand, producing little besides
