subsequently in Gloucestershire, — at Withington, on the Cotswold 

 Hills, in 1852. It is unrepresented in the Stephensian cabinet.

This species may be recognized by its large size (it being the 

 longest of the British Atomarice, though not so large in general 

 bulk as the A. Hislopi) and subcylindrical form, by its densely 

 (though not very deeply) punctured surface, by its ample and 

 convex prothorax, and by its basally much approximated antennae. 

 Like the last species, it is apparently extremely rare, and unrepre- 

 sented in the Stephensian cabinet, — the only specimen which has 

 come under my observation having been captured by myself at 

 Danes Dyke, near Flamborougli, in Yorkshire, during July, 1853. 

 I possess examples, taken at Stettin and sent to me by Herr 

 Kraetz, which differ in no respect from the English one. 



Sp. 3. Atomaria linearis.

The exceedingly narrow, parallel, and subdepressed form of this 

 species, in conjunction with the extreme delicacy of the posterior 

 margin of its (subquadrate) prothorax, will at once distinguish it 

 from the remainder of the genus. It is generally distributed 

 throughout England, though not usually very abundant anywhere. 

 I have taken it at Cransley, in Northamptonshire; at Gravesend and 

 Plumpstead, in Kent ; at Bletchingley, in Surrey ; and at Farming- 

 ton (on the Cotswold Hills), in Gloucestershire ; and it has been 

 captured by Mr. Waterhouse at Gosport, Erith and Highgate, 

 and by Mr. Bates at Leicester. Mr. Haliday also reports its 

 occurrence in Ireland. There are ten specimens under the name 

 of linearis in the Stephensian cabinet, nine only of which how- 

 ever are the true species, — one of them being the A. nigriventris,

Allied to the A. fimetarii, from which, however, it may be readily 

 distinguished by its rather smaller size and more elongated, sub-
