112 THE INSECTS OF GAYNDAH, 



strongly striated, with the interstices convex, and without an 

 abbreviated stria near the scutellum. 



This may not be properly one of the Anchomenidce, it much 

 resembles some of the Feronidce. The palpi, however, and the 

 elongate antennae and legs induce me to place it in this genus. 



129.— Platynus planipennis. n. sp. 

 Length 5j lines. 



Of a brilliant bronzy black above, and of a pitchy black below, 

 with the margin of the thorax, and the extreme lateral edge of 

 the elytra red. Head smooth with the frontal impressions not 

 deep. Thorax nearly square, rounded on the sides, a little nar- 

 rowed posteriorly, truncate at the base, with the posterior angles 

 obtuse and the margin reflexed ; the median line is distinctly 

 marked from the anterior transverse impression to the posterior, 

 and the basal impression on each side is very broad and shallow. 

 The elytra are finely striated, with perfectly flat interstices ; the 

 third interstice has on or near it three large punctures, — the 

 first a little distance from the base in the third stria, the second 

 near the middle in the second stria, and the third nearer the 

 apex in the same stria ; the abbreviated stria near the scutellum 

 is long.

 Length 5 lines. 

 Head more deeply marked than in the last described species. 

 Thorax the same. Elytra narrower and of a greenish hue, with 

 the reddish border larger, and the strise closely punctured ; the 

 interstices between the sti'i^ also appear less flat and broad, and 

 have a shagreen appearance. The legs are yellow. In other 

 respects like P. planipennis.
