154 MANDIBULATA. — COLEOPTERA. 



with the margin punctate ; elytra punctate, opaque, each with the shoulders, 

 apex, and margin, with two discoidal spots, one large, suboval, placed 

 towards the suture, the other shorter, small, external, and towards the base 

 very smooth and very shining; abdomen punctate; legs piceous, punctate. 

 Known by its aeneous tinge, with the disc of the thorax, a large patch on the 

 anterior part of the elytra, and another smaller one adjoining externally, 

 being very glossy and smooth. 



Rare : it has occurred on the Welsh coast. " South Wales, near 

 Swansea, by Mr. Millard." — Dr. Leach.

Hi. quadristriatus. Paykul. — Steph. Catal. 102. No. 1070. 



Ovate, convex, bluish-black, very thickly rugose-punctate : thorax with the an- 

 terior and lateral margin ruggedly-strigose, the hinder margin punctate, leaving 

 a narrow smooth space behind the middle : elytra with an oval space on the 

 disc towards the scutellum, very smooth and glossy, the rest of the surface 

 extremely, and deeply, rugose-punctate, with four very obsolete abbreviated 

 striae at the base, and a single entire one on the suture, recurved at the 

 scutellum, bounding the smooth discoidal spot, and terminating on its outer 

 edge: legs black, with the anterior tibiae strongly quadridentate. 



The very rugose-punctate surface of the elytra, with the obsolete abbreviated 

 striae thereon, combined with the bluish hue, and the strongly denticulated 

 anterior tibiae, characterize this insect. 



Decidedly uncommon : it lias, however, been captured on several 

 parts of the coast. " Barmouth." — Rev. F. W. Hope, and C- 

 Darw'm, Esq. 



Sp> 25. aeneus. Ovatus, wneus, creberrime punctatus, thoracis disco, elytro- 

 rumque macula baseos duplicatd IcBvissimis nitidis, tibiis anticis serratis. (Long, 

 corp. 1—1^ lin.) 



Hi. aeneus. Fabric/us.— Steph. Catal. 102. No. 1071. 



Ovate, aeneous, or blackish, shining : forehead thickly punctured : thorax with 

 the disc smooth, the lateral margins broadly, and the anterior and posterior 

 narrowly, but thickly punctate : elytra broad, with the posterior half and 

 margin very thickly punctate, the humeral callous smooth, and a large very 

 smooth glossy space near the scutellum ; parallel with the suture is an entire 

 simple stria, which is recurved at the base, and continued obliquely over the 

 smooth space on the disc, which it divides in two, the outer division being 

 smallest, having a very short rudimentary stria at the base, and bounded by 

 another stria nearly half the length of the elytra, and in the punctate space 

 beyond is an obsolete fourth one, the part adjoining which is singularly 

 strigose-punctate : legs piceous, with the anterior tibiae serrate.
