62 MANDIBULATA. — COLEOPTERA. 



ably broader and more depressed, and by having the strise on the elytra 

 more punctated. My friend J. Marshall, Esq. took this insect some 

 years back in the north of England, and recently forwarded to me 

 a series of varieties. It was also taken by Messrs. Curtis, Dale, 

 and Weaver, during the past season, I believe on the summit of 

 Skiddaw,, in Cumberland. It is probably the Ne. arctica of De 

 Jean, v. ii. p. 235. 



Sp. 3. Gyllenhalii. Nigra, suhdepressa, antennarum apice tarsisque rufo-piceis, 



elytris striatis,striis suhlcevihus. (Long. corp. 4|^ lin.) 

 Ca. Gyllenhalii. Schonher.—Re. Gyllenhalii. Curtis. — Steph. Catal. No. 87. 



Slightly depressed : black : tips of the palpi and antennse piceous : tarsi and 

 sometimes the tibiae rufous : elytra striated, the striae subpunctate, with two 

 or'three foveae near the third stria from the sutiire ; the margin of the elytra 

 with remote impressed dots. 



f Var. B. Pitchy-black : trochanters and legs ferruginous, apex of the thighs 

 and the tibiae fuscous. Curtis, iii. pi. 103. 



Rare in England, a few specimens only having been recently 

 found in the mountainous districts of Westmoreland, but very 

 abundant in several parts of Scotland in the spring : in the latter 

 country it was first taken in 1810, by the late R. Rawlins, Esq. near 

 Edinburgh, and shortly afterwards by Dr. Leach on Ben Lomond: 

 the Rev. F. W. Hope also took it in plenty in Lanarkshire ; and 

 two years since it was found by Messrs. Curtis and Dale. It also 

 occurs in the mountainous districts of Ireland. 



Genus XXII. — Alp^eus, Bonelli. 



Palpi moderately long : their proportions similar to those of Helobia, but the 

 terminal joint less truncate at the apex : Idbrum transverse : mandibles small, 

 denticulated at the base : labium a Uttle rounded anteriorly, with a small spine 

 in the centre. Antennoe linear : body depressed, elongated : thorax cordate, 

 longer than broad, shghtly margined, straight behind : body sub-depressed, 

 elongate : wings none : legs slender : anterior tibiae with a slight emargina- 

 tion ; anterior tarsi of males a little dilated. 



Distinguished from the two preceding genera by being apterous, 

 by the rotundity of the terminal joints of the palpi, the form of 

 the labium, and of the thorax, which is rather longer than broad, 

 which characters I have drawn out from an injured Helvetic spe- 

 cimen of Al. castaneus ; the antennse and legs are rather more 

 slender and longer than in Helobia. It is an alpine genus, and 

 De Jean considers that its characters are not sufficiently distinct to 

 detach it from Nebria.
