142 MANDIBULATA. — COLEOPTERA. 



I shall subdivide it into sections, in order to render the study of 

 the species less difficult. 



A. With the hinder angles of the thorax obtuse. 

 a. The elytra simiato-truncate at the tip. 

 1. Thorax not attenuated behind. 

 * With the body short, convex. 



Sp. 1. serripes. Ater, thorace subquadrato postice utrinque striold obsolete, pedibtis 



nigris, tibiis valde spinosis. (Long. corp. 6\ lin.) 

 Ca. serripes. Schonher. — Ha. serripes. Steph. Catal. p. 29. No. 248. 



Deep opaque black : head smooth : antennae dull brown, pitchy at the base : 

 thorax subquadrate, obsoletely strigose transversely; the margins slightly 

 rounded, with a slender dorsal channel, and a somewhat obsolete punctulated 

 fovea on each side at the base, reaching to the hinder margin : elytra dull 

 black, sHghtly striated, the strias impunctate, with a minute impression on 

 the second interstice from the suture towards the apex of the elytra, and an 

 interrupted series on the margin : body beneath glossy piceous, the base of 

 the abdomen and the breast subpunctate : legs black, tibise with strong black 

 spines : tips of the palpi rufo-testaceous. 



Schonher introduces the minute impression on the disc of the elytra into the 

 specific character, but that mark is common to most of the Harpali. 



I have one specimen, which was taken on the shores of the 

 Thames beyond Gravesend; and others from Southend and the 

 Isle of Widit. 



Sp. 2. tardus. Niger, nitidus, thorace Iceve postice utrinque foveold impressu, 



elytris striatis, antennis fulvis nigro annulatis. (Long. corp. 4^ — 5 lin.) 

 Ca. tardus, //%-e/^'f'— Ha. tardus. Steph. Catal. p. 29. N'o. 2i9. 



AUied to the last, but smaller, and more oblong: thorax smooth, with an 

 impressed fovea on each side posteriorly, not reaching to the hinder margin ; 

 the dorsal channel rather strong: elytra less dilated on the sides than in 

 H. serripes ; simply striated, the second stria with a minute impression towards 

 the tip of the elytra, and the margin of the latter with an interrupted row of 

 impressions: legs pitchy-testaceous, with the cilia on the tibise rufescent: 

 antennje fulvous, with the base of several joints black ; palpi fidvous, with 

 the base of the joints black. 



" Frequently taken near Southend." — Rev. F. W. Hope. 



Sp. 3. stygius. Convexior, niger, suhopacus, antennis riifo-piceis nigro macvlntis, 



thorace postice utrinque fovea simplici prqfund/i. (Long. corp. 4^ lin.) 

 Ha. stygius. Wilkin MSS. — Steph. Catal. p. 29. A^o. 251. 



Distinguished by its great convexity: entirely deep opaque black: thorax Avith 

 a deep impunctate fovea on each side at the base, remote from the hinder 

 margin, and a very faint dorsal channel : elytra simply striated, with a series
