Helophoetjs platj^icollts, Thoma. 



Allied to S. ceneipennis, but rather narrower, with the sides more parallel, and 

 the thorax (as its name implies) flatter ; the punctures in the strise on the elytra are 

 finer and closer, and the interstices are flatter, and a little nan'ower. Taken in the 

 mountainous districts of Scotland and Ireland, and also in the Shetland Isles (Ent, 

 Mo. Mag., xi, 39). 



Helophoktjs laticollis, Thorns. 



Also belonging to the ceneipennis group, but distinguished by its broad thorax, 

 which is as wide as the elytra, by its elytra being not dilated behind the middle, but 

 thence narrowed towards the apex, with very strong, almost crenate, strise, with 

 narrow interstices, and by the long, and sometimes entirely black, apical joint of its 

 maxillary palpi. This very distinct species has been taken in some numbers at 

 Woking, by Dr. Power (Ent. Mo. Mag., li, 40). 



Helophorus stbigifeons, Thorns. 



A well-marked species, incapable of being confused with any other except S. 

 ceneipennis and H. planicollis, from both of which it differs in being a little larger, 

 in having the sides of the thorax more regularly rounded,- in the broad reflexed 

 margin of the elytra, and in having the longitudinal fovea on the base 

 of the head uniformly narrow. It is probably common (Ent. Mo. Mag., xi, 40). 



Spliceridium marginatum, F. 



The characters assigned to this species hardly suffice to separate it from S. bi- 

 pustulatum, F., of which it appears to be a variety. 



STAPHTLINIDiE. 



Leptusa testacea, Bris. 



This species rests as British on a single example taken by Mr. Champion out of 

 sea-weed at Whitstable, Kent. It is described as being long, linear, flattened, tes- 

 taceous in colour, with dark abdomen, very short elytra, and long antennae. When 

 alive, it has much the general appearance of Fhytosus balticus (Ent. Mo. Mag., ix, 5). 



Aleochara tillosa, Mann. 



This insect very much resembles A. grisea^ Kraatz, in general appearance ; it 

 appears, however, to come nearer to A. lanuginosa, Gr., than to this last mentioned 

 species : it differs in having the 2nd and 3rd joints of the antennas equal in length ; 

 in being flatter, more parallel, and much less shining ; and also in the punctuation 

 of the abdomen. Taken in several localities, Newcastle, Braemar, &c. (Ent. Mo. 

 Mag., vii, 275). 



Aleochara hibernica, Rye. 



This species rests entirely on a single specimen found by Mr. Champion on the 

 top of Slieve Donard (a mountain 2800 feet high, in Co. Down, Ireland). It is of 

 the size and somewhat of the build of Homalota camhrica, Woll., but darker, more 

 convex, elongate, and shining, less closely punctured, with shorter antennae, &c. Its 

 general appearance is not that of an Aleochara at all, but it has its anterior tarsi 5- 

 jointcd (Ent. Mo. Mag., xii, 175).
