103. Pterostichus LiEviGATUs, n.sp. 



Oblong-ovate, depressed, black, nitid, elytra slightly iridescent. 

 Head as in the last species, antennse slender, piceous. Thorax 

 exactly as in P. crenulatus, the anterior angles being perhaps less 

 acute, and the basal impressions i-ather more linear. Elytra 

 wider than the thorax and nearly three times the length, striate, 

 the strias very minutely punctate, the interstices flat, no short 

 scutellar stria. Legs piceous, moderately stout. 



Long. 4 lines, lat. 1^ line. 



I have placed the last two species under the old sub-genus 

 Pterostichus, because I have been unable to ascertain under which of 

 the many sub-divisions of the genus Feronia, made by the late 

 Baron de Chaudoir, they would come. 



The Feronides of Australia are very numerous, and notwith- 

 standing all that has been done by Count Castelnau, and Baron 

 de Chaudoir, I know of no group more i-equiring careful revision. 



104. SiMODONTUS OCCIDENTALIS, n.sp. 



Oblong-ovate, subdepressed, black, very nitid, the elytra of a 

 bronzy-black. Head scarcely longer than wide, smooth, the 

 frontal impressions straight, linear, very slightly diverging behind 

 and reaching to past the middle of the eyes, the antennae short, 

 piceous. Thorax transverse, much wider than the head, a little 

 rounded on the sides, the base slightly wider than the apex, the 

 posterior angles nearly square, the median line lightly marked 

 except near the base, and the basal impressions short, deep, and 

 minutely and rather rugosely punctate. Elytra a little wider 

 than the thorax and more than twice the length, strongly striate, 

 the interstices convex, a short stria at the base of the second 

 interstice from the scutellum. Under surface and legs piceous, 

 the latter short and moderately stout. 



Long. 3 lines, lat. 1 line.
