60 MANDIBULATA.— COLEOPTERA, 



also occurs on the opposite shores of the Bristol Channel, having 

 been found in plenty at Barnstaple and Bideford by my friends 

 Mr. Raddon and Capt. Blomer; on the shores of the Taw, near 

 Braunton Burrows, North Devon, by Mr. Curtis ; and at Weston- 

 super-Mare, in Somersetshire. It is likewise found on the coast 

 of Lincolnshire. 



Sp. 3. livida. Niffra, ore, antennarum hasi, pedibus, thoracis medio, elytro- 



rumque margine anguste pallidis. (Long. corp. 7 — 8 lin.) 

 Ca. lividus. Linne.—'Ne. livida. Curtis, i. pi. 6.—Sieph. fatal. JVo. 83. 



Shining black ; the mouthj base of the antennse^ legSj and a narrow margin to 

 the elytra pale yellow : thorax the same, with a deep transverse impression 

 in front and behind, between which and the edge is black : elytra striated : 

 antennae externally fuscescent. 



Ne. livida was first discovered many years ago by Wm. Spence, 

 Esq. F. L. S., on the shores of the Humber, a short distance from 

 Hull, near which spot a second specimen was afterwards taken by 

 Mr. Wilkin ; those were the only specimens known, until last year, 

 when three were forwarded to London from Scarborough, one pair 

 of which came into my possession; and Mr. Backhouse informs 

 me that he has lately taken the insect in plenty beneath stones, &c. 

 on the coast near that place. 



Sp. 4. picicornis. Plate IV. f. 3. — Niger, ore antennis pedibusque piceo- 



ferrugineis, capite piceo-rufo, (Long. corp. 6^ — 7^ lin.) 

 Ca. picicornis. Fabricius. — Ne. picicornis. Steph. Catal, No. 84. 



Pitchy-black: head reddish, dusky behind: eyes dusky: thorax and elytra 

 deep black, the latter striated : mouth, antennae, and legs pitchy-ferruginous: 

 thorax with a strong impressed longitudinal line ; a deep fovea on each side 

 at the base, and a punctulated depression behind and in front. 



Of this insect most cabinets are deficient. The first indigenous 

 specimen which came under my notice was taken by Dr. Leach, 

 near Ashburton, in Devonshire, and is in the British Museum : it 

 was afterwards found by the Rev. F. W. Hope (who supplied me 

 with a pair), in Longmont Forest, Shropshire.

Palpi moderately long: labial with the two basal joints short, third long, pilose, 

 fourth longer, truncate: internal maxillary palpi with the joints nearly equal*; 

 external with the basal joint minute, second long, stout; third short, clavate; 



* In the tabular view, p 45, the characters of the genera Nebria and Helobia 

 are accidentally reversed.
