18 MADEIRAN COLEOPTERA. 
49. Bradycellus excultus. 
Bradycellus excultus, Woll., Ins. Mad. 61. tab. ii. f. 4 (1854). 
Inhabits the mountains of Madeira proper, assuming two distinct 
forms,—one in which the prothorax is pale (or nearly so), and 
another in which it is dark. Very rare. 
Genus 23. TRECHUS. 
Clairville, Ent. Helv. ii. 23 (1806). 
50. Trechus fimicola. 
Trechus fimicola [script., per errorem, fimicolus], Woll., Ins. Mad. 63 
(1854). 
Inhabits Madeira proper, generally at low elevations. I have 
taken it hitherto only in the gardens of Funchal, and at Santa Anna. 
Rare. 
51. Trechus nigrocruciatus. 
Trechus nigrocruciatus, Woll., Ins. Mad. 64. tab. ii. f. 1 (1854). 
Inhabits the mountains of Madeira proper, attaining its maximum 
towards the upper limits of the sylvan districts. It does however, 
in some localities, descend considerably lower, as I have captured it 
at S. Antonio da Serra, and Mr. Mason in the Boa Ventura, at about 
2500 feet above the sea. Rare. 
52. Trechus levis, n. sp. 
7’. subovatus nitidissimus depressus nigro-piceus, prothorace sub- 
quadrato basi leviter angustato angulis ipsis posticis acuminatis, 
elytris latiusculis levissime striatis, striis exterioribus evanescen- 
tibus, limbo lete flavo-testaceo, antennis subrobustis infuscatis, 
pedibus pallidis. 
Long. corp. lin. 13-14. 
7’. subovate, depressed, exceedingly shining, and piceous-black. 
Prothorax subquadrate, but more evidently narrowed behind than 
in the 7. flavomarginatus, and with its extreme posterior angles, 
moreover, more distinctly thickened and prominent. Hlytra rather 
wider, a little more rounded at the sides, and much less deeply 
striated, than in that species,—the outer striz indeed being 
evanescent: also, more brightly and broadly margined with pale- 
testaceous. Antenne and legs as in that insect,—the former, 
however, being just perceptibly longer and more robust. 
In the Insecta Maderensia I recorded this insect as a variety of 
the following one, but a further acquaintance with it (resulting from
