454 ON CARABID.-E FROM WEST AUSTRALIA, 



with head larger, postocular prominences more developed, pro- 

 thorax less dilatate on sides, metasternal episterna and epimera 

 shorter. It shows an evident natural affinity to /'. ovipennis, 

 SI., therefore I expect the ^ will prove to have the basal joints 

 of the four anterior tarsi without spongiose tissue beneath. The 

 sjDecimen before me shows evidence of a lengthened immersion in 

 alcohol, and for this reason I believe the elytra are naturally 

 Isevigate. 



32. P. ANGULicEPS, n.sp. 



9. Elliptic-oval, subcylindrical, laevigate; head with posterior 

 angle of outer margin of buccal fissure prominent, obtuse (sub- 

 rectangular) ; prothorax convex, strongly angustate posteriori}^, 

 bordered on base; elytra oval, convex (7"5x5mm.); posterior 

 trochanters pointed at apex. Shining, upper surface bronzed- 

 black — tending to greenish-black in middle; under surface rather 

 piceous with bronzy metallic reflections on posterior ventral 

 segments ; legs piceous-black with metallic tinge on femora ; 

 antennae, tarsi and palpi reddish-brown. 



Head ordinary ; A^ertex convex, not transversely impressed ; 

 eyes round, convex, prominent ; orbits lightly swollen behind 

 eyes. Prothorax nearly as long as broad (3'8 x 3'85 mm.), convex, 

 declivous to base; sides strongly rounded; anterior margin widely 

 emarginate in middle; anterior angles obtuse, not marked, pro- 

 jecting considerably from head ; base truncate ; basal angles 

 almost rectangular; border narrow, not sinuate before base, entire 

 on base; median line strongly impressed. Episterna of meta- 

 sternum almost square; epimera short, about twice as broad as 

 long. Ventral segments 3-6 roundly foveate on each side. 



Length 13, breadth 5 mm.

Closely allied to and almost exactly resembling P. ambiguus, 

 SI. The chief points of diiference seem to be the postocular 

 prominences smaller and the elytra more shortly and strongly 

 rounded at the shoulders, which gives them a more evenly 

 rounded appearance. P. ambiguus has the outer margin of the
