Walton, although he has remarked some of the differences between the two 

 insects, considered specimens of squamulatus, sent to him on two occasions by 

 Chevrolat, to be small immature varieties of a/ristatus, and has accordingly adopted 

 Olivicr's najne (which is the oldest), being persuaded that Gyllenhal was misled by 

 a want of varieties. 



T. squamulatus, apparently found most commonly on the south coast, is usually 

 smaller than T, aristatus, and of a lighter colour ; its thorax is not so transverse, 

 being much less expanded at the sides, its legs and antennas are rather shorter, the 

 basal joint of the latter being somewhat abruptly contracted in the middle, and 

 the setas on its elytra are much shorter, and more slender and uniform ; whilst in 

 T. aristatus they are erect, long, stout, and individually very decidedly thickest at 

 the tip. My specimens of the latter were taken at Wickham and Mickleham. — Id. 



Note on the occurrence of a species of Omaluitn new to Britain. 



Omalium pineti, Thomson, Skand. Col., iii., 209, 2. I took one example of 

 this species under the bark of a fir stump at Rannoch, in June last. 



It is alhed to 0. jy^anum ; differing in being smaller, especially narrower, with 

 fuscous elytra, of which the punctuation is finer and more sparing, and having no 

 impressions on the anterior margin of the thorax. — D. Sharp, 12, St. Vincent 

 Street, Edinburgh, November, 1865. 



Note on the occurrence of a species of Leptura new to Britain. 



Leptura RUi^'A, Brulle, Mulsant, 269. — Mr. Thorncrofl; captured a single male 

 example of this fine species (now in my collection) at Holme Bush, Sussex, during 

 the past summer. It appears to be rare, and found in the south of Fi'ance, Spain, 

 Turkey, and Greece. 



It is next to L. scutellata, and about the same size, vdth the head, thorax, and 

 antennae black (the first joint of the latter sometimes red), and elytra brownish- 

 red, punctured coarsely at the base, and finely at the apex. The under-side is 

 covered with ashy pubescence, the abdomen being more or less red towai-ds the 

 tip. — Id. 



Note on the capture of cm Atomaria new to Britain. 



Atomaria impressa, Erichson, Ins. Deutschl., iii., 389, 19. — I found a single 

 example of this species at the bottom of a hay -rick, Lee, Kent. 



Of our species it is in the same section as, and nearest to, munda (having tho 

 thorax abruptly depressed in the middle behind), but is larger than that insect, 

 with unicolorous (brown) elytra and thorax, thinner antenna, and punctuation not 

 so strong and close. — Id. 



Note on Tachyphorus ruficollis, Qrav. — I think that tke name of tliis species must 

 be removed from the British Catalogue ; for all its exponents, seen by me in col- 

 lections (including the specimens taken by Mr. WoUaston), in nowise agree with 

 the descriptions of T. ruficollis, but are tho T. nitidicollis of Stephens. 



There is, also, much confusion about tho latter insect. Mr. Wollaston, in a 

 note published in tho Zoologist for 1855, informs us of its capture in Ireland, 

 adding that specimens of it, sent by him to Drs. Schaum and Kraatz, had been 

 returned as belonging to a species unknown to them ; and I see that it ranks as a
