170 MANDIBULATA. COLEOPTERA. 



the margins paler ; a somewhat deep longitudinal dorsal line, a curved im- 

 pression, and a small fovea on each side at the angle : elytra very flat, smooth 

 glossy ehesnut, or ferruginous, with the edges paler ; each with four or five 

 faint impunctate striae towards the suture, the marginal ones being more 

 ohsolete, and not touching the apex ; the margin itself is striated, and has 

 one or two impressions at the base, and a few towards the tip : the legs and 

 palpi are' pale testaceous : the antennae ferruginous. It varies in colour. 



Found in damp places round London and Southend; also in 

 Suffolk, Norfolk, and Yorkshire, common. 



Sp. 10. fuscipennis. Piceus, nitidus, antennis fedibusque pallidi ferrugineis, 



elytris juscescentihus, striis dorsalibus profundis. (Long. corp. if lin.) 

 Tr. fuscipennis. Wilkins MSS.—Steph. Catal. p. 35. No. 330. 



Probably a mere variety of the foregoing : it differs in being of a deeper colour, 

 and in having the elytra more profoundly striated, the striae impunctate : the 

 head is pitchy : the thorax dusky-black : the elytra deep castaneous-brown, 

 the striae rather deep and impunctate : the legs and palpi are rusty-red, and 

 the antennae ferruginous. 



Found in Norfolk, and also near London. 



Sp. 11. tristis. Nigro-piceus, nitidus, antennis pedibusque ferrugineis, elijtris 

 subcastaneis, striis dorsalibus subpunctatis. (Long. corp. 1^ — If hn.) 



Ca. tristis. Faykul. — Tr. tristis. Steph. Catal. p. 35. No. 331. 



Very similar, and possibly not sufficiently distinct from the two last : deep sliining 

 pitchy-black: head as in the two preceding ; generally black : thorax rather 

 castaneous, with a moderate dorsal Kne, and a slightly punctate fovea on each 

 side at the base : elytra striated internally, the striae obsoletely punctate, the 

 outer ones nearly evanescent, and vanishing at the tip : legs pale testaceous : 

 antennae ferruginous, with the base palest. 



Frequently captured near London and Southend. 



b. Thorax rather elongate, attenuated posteriorly, the angles obsolete. 

 Sp. 12. meridianus. Niger, nitidus, thorace post ice attenuato, elytris striatis, 



hasi suturd pedibusque pallidis. (Long. corp. 1^ — If lin.) 

 Ca. meridianus. Linne. — Tr. meridianus. Steph. Catal. p. 34. No. 328. 



Deep glossy black : head smooth : thorax sUghtly attenuated posteriorly, deep 

 black or piceous, rather convex, with a faint dorsal line, and a large subpunc- 

 tate fovea on each side at the base, the margins sometimes testaceous : elytra 

 slightly convex, not very deeply striated, the striae impunctate; shining 

 black, the base with a large pale spot, more or less dilated externally, the 

 suture and the outer margin also pale, the former rather blackish at the base : 

 legs and antennae ferruginous, the former with the thighs sometimes dusky, 

 and the latter generally brownish at the tip. 



Common near London, and I believe pretty generally distributed.
