110 THE INSECTS OF GAYNDAH, 



broad and lightly but distinctly striated, with the abbreviated 

 stria near the scutellara two lines long. The interstices are 

 broad and very flat. 



This species differs from G. prolixus Erichs., upon which the 

 genus is founded by Baron de Chaudoir, in several particulars, 

 the most evident being the much finer striation of the elytra and 

 greater flatness of the interstices. 



123. — PiEClLUS SDBIRIDESCENS. n. Sp. 



Length 4| lines. 

 Black, nitid. Head with two short impressions in front. 

 Thorax longer than the breadth, rounded at the sides, rather 

 narrowed behind, truncate at the base, and with the posterior 

 angles obtuse and rounded, the median line lightly marked, and 

 the basal impressions deep and rather long. Elytra iridescent 

 and strongly striated, with no abbreviated sutural stri^, and with 

 the interstices convex. The legs and antennae are of a reddish 

 brown. 



124. — P.a:ciLus ateonitens. n. sp. 

 Length 4 lines. 

 In form and general appearance very much resembling P. 

 subiridescens. It differs in having the frontal impressions 

 smaller and more lightly marked, and in having the spaces be- 

 tween the strijB on the elytra more flat. It is also a much smaller 

 insect, and with only a trace of iridescence on the elytra. 



125. — Argutok fovetpennis. n. sp. 

 Length 3|^ lines. 

 Black, nitid. Head with the frontal impressions long and 

 well marked. Thorax transversal, rounded behind the anterior 

 angles and square at the base with the median line well marked, 

 the inner basal impression broad and deep, and the outer very small. 

 Elytra duller than the thorax, — of a brownish tinge, with an 

 indistinct dull red margin, — and striated, with the abbreviated 

 ptria long and joining the first stria from the suture, and with the 

 interstices flat ; the third with three shallow fovese, the first above
