large numbers. Its " head-quarters " was a space not twice as big as an ordinary 

 room, scarcely a straggler being seen at a distance of twenty yards. Most of the 

 examples were got by sweeping the grass, but it could easily be seen and picked off 

 the stems, and I caught several on the wing. The Heptaulacus had the place all to 

 itself, the only other beetles to be seen in the sweeping-net being Isomira murina 

 and an occasional Dascillus cervinus. 



We are at a loss to account for this extraordinary assemblage of so rare a beetle : 

 though Dr. Sharp's suggestion that it is attached to rabbit's dung (the runs of these 

 animals being numerous in the locality), seems at least feasible. 



Abdera 4^-fasciata again turned up, not rarely, among small Boleti on the old 

 hornbeam tree, where I took it in 1886, and the same tree now supports a thriving 

 colony of Melasis buprestoides. — James J. Walker, 23, Ranelagh Road, Sheerness :

Abrceus granulum, Er., at Cobham. — A few minutes before we fell in with the 

 Heptaulacus villosus, I found several Abrcei at the foot of an old ash tree, under a 

 hard woody fungus, on the spores of which they were apparently feeding. These I 

 handed to Dr. Sharp as A. globosus, a fairly common insect in the Park; but on 

 visiting him two or three days afterwards, he showed me one of them, noticed by 

 us at the time of capture as being very small, which he had determined to be the 

 very rare A. granulum, Er. I went to look for it again on June 29th, and found 

 three specimens in the very same spot as before, in company with A. globosus. 



The day being very hot, and favourable for collecting, some good beetles appeared 

 in the sweeping-net, among them being Homalota hepatica (two in one sweep), 

 Thalycra sericea (1), Saprinus virescens (1), and Conopalpus testaceas (2), all, except 

 the first-named, being new to the locality. Pocadius ferrugineus, also an addition 

 to the Chatham list, was found in toadstools, in company with Oxyporus rufus. —

A new locality for Potaminus substriatus.- — At Easter, I was staying for a day 

 or two at Bodle Street, a small village near Ashburnham, Sussex, and while there took 

 a few specimens of this rare beetle. I have not had a chance of re-visiting the 

 locality until last Monday, when I went prepared for a day's Potaminus hunting. 

 I reached the ground about 11 o'clock, and worked steadily on till nearly six. By 

 that time I had thoroughly hunted about a mile and a half of the stream, and had 

 secured some eighty specimens. I see that Rev. Canon Fowler says, it is found under 

 clods and stones, " but not apparently under submerged logs;" when I could find 

 the logs, they proved quite as productive as the clods. On one small piece I took 

 ten specimens of Potaminus, and saw quite a score of Orectochilus villosus skipping 

 about. 



I also took four specimens of Deronectes latus, a species which I have also taken 

 in numbers in a rapid stream at Gruestling during the last month. — W. H. Bennett, 

 11, George Street, Hastings : July, 1889. 



The black variety of Limenitis Sibylla. — On the 6th inst., at Lyndhurst, I had 

 the good fortune to capture a fine specimen of the black variety of Limenitis Sibylla.
