114 NIYLACTICT/S. 



Head short, depressed, very slightly elongated in front ; labrum and 

 anterior surface of a paler colour (almost cinereous) : eyes black, 

 slightly prominent, distant; between them, and extending longi- 

 tudinally as far as the insertion of the antennae, is a medial Y-shaped 

 fovea : surface finely and closely punctate. Thorax transverse (almost 

 quadrate) ; sides marginate, broad at the base, but considerably con- 

 stricted anteriorly; the margination (when viewed laterally) is abruptly 

 depressed from the humeral angle in the direction of the outer margin 

 of the eyes ; a very faint medial longitudinal line is indistinctly ap- 

 parent (when viewed in some lights), and the basal transverse de- 

 pression (so distinct in many of the allied species) is almost obsolete ; 

 surface finely punctate. Sciitellum triangular, fuscous. Elytra robust, 

 distinctly punctate-striate, with the humeral angles less prominent, 

 and more closely rounded off from the thorax than in other species 

 of this group. Antennas filiform, with the first joint dilated towards 

 the apex and inflected outwards ; the second short, ovate ; the third 

 longer than the first, flavo-ferrugineous ; the fifth and sixth joints 

 more distinctly fuscous. Legs pale ferrugineous ; suffused on the upper 

 surface of the anterior tarsi and tibiae, as well as at the apex of the 

 posterior femora, with fuscous. 



Of a dark-green colour in recently captured specimens ; this colour 

 would seem, however, to be evanescent ; one example before me has 

 almost entirely lost it, and is of a faint pale-green colour. 



This species is almost identical with the figure and description of 

 (Edlonychis viridis of Perty (Delectus Anim. Arctic, p. 110. tab. xxii. 

 fig. 6); it wants, however, the flavous marking on the head and 

 thorax. I subjoin Perty's description, which has reference, doubtless, 

 to an allied species of this genus*. Taken by Mr. Bates, in the 

 district of the Amazon. In the cabinets of Mr. Bates and the Rev. 

 H. Clark.
