88 MANDIBULATA. COLEOPTERA. 



the marginal strise, which are placed closer together near the apex : body be- 

 neath shining black : legs pitchy^ slender : the hinder tibiae curved externally. 

 I have seen one specimen only of this insect (whieli is very- 

 distinct from any of the following). It was taken in the north of 

 England during the past season by Mr. Weaver, from whom I ob- 

 tained it. . 



Sp. 6. viduum. Ovatum nigj^um, supra obscure virescens, elytris profundius 

 striafis, punctis trihus disci impresses. (Long. corp. 3^ — 4 lin.) 



Ca. viduus. Illiger. — Ag= viduum. Steph. Catal. JVo. 127. 



Head black, smooth^ shining : palpi and antennse black : thorax convex above, 

 smooth glossy green-black, obsoletely strigose, with a slight central channel, 

 and a large fovea on each side at the base : elytra oblong-ovate, much broader 

 than the thorax : shoulders rounded, rather convex, blackish-brass or greenish, 

 rather deeply striated, the striae dehcately punctated ; between the second and 

 third striae from the suture three impressed dots, and an interrupted series on 

 the margin : body beneath glossy black, rather smooth : legs elongate, black. 



There is the greatest imaginable affinity between this species 

 and the four following; but the beautiful figures of Sturm point 

 out the distinctions of some of them, and others are discriminated 

 by characters that may be easier seen than expressed. This species 

 occurs near London, in Battersea and Copenhagen-fields, and in 

 Shropshire. 



Sp. 7. versutum. Nigrum, aid nigro-wneum, nitidum, thorace convexo, elytris 



. parum dilatatis, teniiA striato-punctatis. (Long. corp. 4 lin.) 



Ag. versutum. Sturm. — Steph. Catal. No. 128. 



AUied to the last, but somewhat less and narrower : glossy black, or tinged with 

 aeneous: thorax with the sides rounded: the disc convex anteriorly, very 

 smooth and shining, depressed posteriorly, with a large subpunctate fovea on 

 each side at the base, and a slight longitudinal channel ; elytra emarginate at 

 the base, a Httle convex, striated, the striae punctate, with two deep impres- 

 sions on the second stria, and one on the third, from the base, as in the last 

 described insect : body beneath and legs glossy black, the latter sometimes 

 piceous. 

 Occasionally found in the metropolitan district. 



Sp. 8. laeve. Nigrum, nitidum, thorace breviore, latitudine fere elytrorum, elytris 

 m,inus dilatatis. (Long. corp. 3^ — 4 lin.) 



Ag. laevis. De Jean. — Steph. Catal. No. 129. 



Similar to the next, but the elytra less broad ; deep glossy black : the thorax 

 very wide, with an impressed longitudinal channel, and an elongate fovea on 

 each side at the base : the elytra scarcely broader than the thorax, rather 

 convex, striated, the striae obsoletely punctate ; the base sUghtly emarginated ; 

 the disc with three deeper impressions. 

 Taken near London, and at Swansea.
