BEMBIDIID^. — PHILOCHTHUS. 7 



each side between the eyes : thorax convex, with a faint dorsal line, and a 

 simple impunctate fovea on each side at the base : elytra with the suture and 

 apex slightly rufescent, faintly punctate-striated, the interstices impunctate : 

 legs entirely of a fulvous red : antennae dusky, with the base reddish. 



On the sand-hills, near Swansea, in Glamorganshire. 



Sp. 8. minutissimus. Ferrugineo-piceus, elytris pallidiorihus striis duabus obso- 

 letioribus dorsalibus. (Long. corp. | — 1 lin.) 



Ta. minutissimus. Leach MSS. — Steph. Catal. p. 36. No. 350. 



Of a pitchy ferruginous, somewhat opaque : head blackish, with a longitudinal 

 impression in front on each side : thorax with a very faint dorsal line, the 

 hinder angles slightly prominent; near each a subtrigonal simple fovea: 

 elytra rather slender, with two somewhat obsolete impunctate striae on each 

 near the suture ; the rest of the disc smooth : legs and mouth pale rufo- 

 fulvous : antennas pitchy, with the apex dusky. 



Unquestionably the smallest of the indigenous Geodephagous insects, at least so 

 far as I have hitherto observed : upon a casual glance somewhat resembling a 

 species of Hydraena. 



Found on the Glamorganshire coast. 



Genus LXVII. — Philochthus * mihi. 



Palpi as in Tachys : labrum transverse, entire : mandibles broad, short, bent, 

 not very acute : mentum emarginate anteriorly, with an acute central tooth. 

 Antenna? pubescent, the basal joint naked, the second joint shorter than the 

 fourth : head ovate : thorax transverse, slightly emarginate anteriorly, trun- 

 cate posteriorly ; the sides dilated, obtusely rounded, deeply notched at the 

 hinder angle : elytra oblong-ovate, subconvex : anterior tarsi of the males with 

 the basal joint dilated. 



The name Leia having been used by Meigen for a genus of 

 Diptera several years since, it became necessary to employ a new 

 term to designate the insects of the genus Leja of Megerle ; I have 

 therefore proposed the above, in allusion to the usual place of 

 resort which the species affect : the species may be distinguished 

 from Tachys by the thorax, which has a deep emargination at its 

 hinder angle; the second joint of the antennae is also considerably 

 shorter than the fourth. 



Sp. 1. aeneus. JEneus, elytris immaculatis, punctato-striatis, upice losvihusy 



plicatis,femoribus nigris, tibiis tarsisque piceis. (Long. corp. 2^ lin.)
