THE yOUNG NATUEALIST 



CARABUS. 



C. intricatus. — Deep violet ; elytra much 

 wrinkled longitudinally; legs black. Very 

 rare. Has occurred in Devonshire. 



C. auratus. — Hdad and thorax green ; 

 elytra with three raised longitudinal rihs of a 

 green colour, the spaces between being 

 bronze ; legs red. Rare, a doubtful native. 



C. nitens. — Head and) thorax cojppery: 

 elytra rcith three ribs which are black ; 

 whilst the intervals are bronze-green ; outer 

 margin of the elytra bright coppery ; legs 

 hlach. Not uncommon in swampy places. 

 I have collected the species on Strensall 

 Common, near York. 



C. clatlwatus. — Dark greenish bronze ; 

 elytra with three ribs, between each two of 

 which is a row of large round depressions. 

 Occurs in Scotland and the north of Ireland. 



C. granulatus. — Bronze. Elytra with three 

 ribs, between each two of which is a ro?v of 

 elevations (granules.) Common. 



O. cancellatus. — Similar to granulatus, 

 but with the basal joint of the antennae 

 and the femora, red. Rare, questionably 

 British. 



C. monilis — Variable. Bronze, green, or 

 black. Each elytron with three rows of 

 granules, between each two of which are 

 three raised lines. The var. consitus has 

 the central raised line more prominent than 

 the lateral ones. Tolerably common, es- 

 pecially in the south. 



0. arvensis. Resembles monilis in colour 

 and sculpture, but is much smaller ; the 

 thorax is narrower; and it has a flatter 

 appearance. We took this species last 

 spring, on the mountains near Llangollen. 

 It never occurs except at a considerable 

 elevation. 



G. catenulatus. Black, with a violet mar- 

 gin to the thorax and elytra. Sculpture of 

 elytra somewhat like monilis, but less dis- 

 tinct. Common in healthy situations. 



C. molaceus. Black, with a violet margin 

 to the thorax and elytra — the latter witlwut 



any ribs or rows of elevations, but rather 

 rough in appearance. Common. 



C glabratus. — Blach, without a violet mar- 

 gin ; the elytra almost smooth. A mountain 

 species, not rare in Scotland. 



C. nemoralis. — Head and thorax black, 

 the latter with violet margins ; elytra bronze 

 or greenish, with three rows of depressions. 

 Common. 



C. convexus. — Head and thorax black, the 

 latter with bluish margins ; elytra blach, 

 with three rows of somewhat indistinct de- 

 pressions. A small species. Rare. 



The individuals of this genus vary con- 

 siderably in size, nitens, convexus, and arven- 

 sis being about | inch, whilst intricatus, viO' 

 laceus, catenulatus, and monilis are among 

 the largest, measuring from lo to 14 lines 

 (12 lines ^ I inch.) The males of this genus 

 have the first four joints of the anterior 

 tarsi widely dilated ; in the female these 

 joints are not broader than those of the other 

 feet ; the latter are also usually more rounded 

 at the sides, and also larger than the males. 



NEBRIA. 



1. Size, over half-an-inch. 



Elytra yellow, with dark markings. . . , 



Complanata 



Elytra pitchy black, with pale yellow 

 margins lAvida. 



2. Size, under half-an-inch. .. .^remcoZZis 



and Gylle 'iluilli. 



Gyllenhalli differs from brevicollis in being 

 narrower, with the legs and antennae gen- 

 erally darker ; and the elytra, which in the 

 latter are crenate striate, in OyllenhalU 

 are very finely punctured. 



Convplanata is very local, but abundant 

 where it does occur, viz. on shores of the 

 West of England and Wales, as Swansea, 

 &c. Livida occurs abundantly in crevices 

 of the clay cliffs at Scarborough ; brevicollis 

 is one of the most abundant beetles every- 

 where ; whilst Gryllenhalli occurs only on 

 the Welsh and Scotch mountains at a con- 

 siderable elevation.
