473 THE INSECTS OF KING'S SOUND AND ITS VICINITY, 



101. Rhytisternus limbatus, n.sp. 



Of more robust form than the last, black or reddish- brown, 

 nitid. Head as wide as long (labrura excluded), impressed as 

 in the last, the antennae and palpi piceous. Thoiax wider than 

 the head and nearly square, slightly rounded on the sides, the 

 anterior angles subacute, the posterior nearly rectangular, the 

 l>ase and apex of equal width, the median line only impressed 

 distinctly at the base, about the same length as the basal impres- 

 sions, which are deep, the outer basal impressions strong and 

 punctiform. Elytra a little wider than the thorax and more than 

 twice the length, strongly striate on the first four and the 

 lateral striie, the others obsolete, the interstices slightly convex, 

 no sutural stria, a wide more or less distinct yellowish border to 

 the sides and apex of the elytra. Under surface piceous red, legs 

 yellow, short and stout as in the last species. 



Long. 4 linev,^ lat. 1^ line. 



102. Ptkrostichus crenulatus, n.sp. 



Elongate-ovate, black, nitid. Head much longer than wide, 

 smooth, the frontal impressions short not deep, formed of two 

 impressions on each side scarcely united — one on the cly|)eus, the 

 other immediately behind the clypeal suture; the antennae piceous, 

 filiform, the first four joints smooth, the rest pubescent, the last 

 «longate-ovate. Thorax wider than the head, longer than wide, 

 very nitid, the anterior angles slightly produced and sub-acute, 

 the sides slightly rounded and distinctly margined, the base a little 

 wider than the apex, with the posterior angles rounded, the 

 median line lightly marked and the basal impressions broad, deep 

 and punctate at the base. Elytra not wider than the thorax at its 

 widest part, and three times the length, deeply striate, the striae 

 deei)]y punctuied and narrow, the interstices raised and narrow, 

 having a crenulated appearance from the small sharp punctures of 

 the striae, no short scutellar stria. TJrtder surface and legs 

 piceous, very nitid, the latter rather slender, the prosternum with- 

 out margin, smooth. 



Long. 4^ lines, lat. 1^ line.
