14 ADEPHAGA. [Leistus. 



A rare species, attached to mountainous districts. Lake district, Cumberland, &c. ; 

 Skiddaw ; Cheviots ; Scotland, Highlands, Tweed, Forth, Moray, Tay ; Ireland, 

 Croagh Patrick, Mangerton, &c. 



Xi. fulvibarbis, Dej. Dark blue, sometimes almost black ; thorax 

 short, very strongly rounded at sides and contracted towards base with 

 side margins narrow and but slightly raised ; elytra rather wide with 

 very deep and strongly punctured striae ; legs red, base of femora often 

 darker. L, 6|-7| mm. 



Very common in England ; Scotland, local. Lowlands ; Ireland, near Dublin and 

 Belfast. 



Ii. ferrug-ineus, L. {spmiJahris, Panz.). Upper side entirely 

 lighter or darker red-brown ; thorax short, very strongly rounded at sides 

 and contracted to base, with posterior angles sharp right angles ; elytra 

 long oval with deep and strongly punctured striae, which become shallower 

 at sides, but are always traceable ; legs testaceous. L. 6 mm. 



Rather common in England; Scotland, only recorded as Scotch by A. Murray, 

 "not uncommon at Pressmenan, Lammermuir Hills ;" Ireland, apparently very local. 



Xi. rufescens, F. {terminatus, Panz.). Eather darker than the 

 preceding ; sometimes with thorax and elytra entirely dark piceous ; 

 easily distinguished from L. ferruginens by its black head and the blunter 

 angles of the thorax ; the elytra are rather wider than in that species, 

 and the stria3 are feebler and almost obsolete at the sides ; legs testaceous. 

 L. 6 mm. 



This species seems more attached to damp places at the roots of grass than the 

 preceding, and is very often taken by sweeping ; it is local but not uncommon 

 throughout the country; Scotland, scarce, Lowlands ; Ireland, very local, Armagh, 

 Antrim. 



NEBRIA, Latreille. 



This genus comprises the old genus HeJohia, Curtis, and at one time 

 included Pelophila, Dej., as well ; the species are very numerous, and are 

 Avidely distributed throughout Europe, Asia, and North America. The 

 species of Nehria proper are for the most part inhabitants of the sea 

 coast, while the species of Helohia (represented in our fauna by N. hrevi- 

 collis and N. G ijUenTialii) are inland insects : this does not, however, 

 always hold good. They vary considerably in structure, but for the most 

 part are remarkable for their short thorax, which has the sides strongly 

 contracted towards base as in Leistus. 



As a rule the species belonging to the sub-genus Helohia are dark-coloured ; some, 

 however, e.g. N. catenulata and iV". metallica, are very brightly tinted with iridescent 

 metallic colours. 



The larva of N. hrevicoUis is figured by Schiodte (Part iii., PL xiv. 1), and it is 

 also described by Blisson (Ann. Fr. 1848, 73). It is dark brown or luteous above 

 and straw-coloured below; the head is somewhat orbicular, not as broad as prothorax, 

 to which it is joined by a rather long and distinct neck ; the prothorax is transverse, 

 and bears a large finely margined shield which nearly covers its whole surface ; the 

 dorsal abdominal shields are not margined; the ninth abdominal segment is very 

 short, almost hidden, and the anal appendage is long and cylindrical ; the ccrci are
