490 ON CARABIDjE from west AUSTRALIA, 



Head lightly biimpressed between antennte; eyes convex, pro- 

 minent, enclosed behind. Prothorax transverse (2-6 x 3-2 mm.), 

 much wider across base than apex; sides rounded; apex bordered, 

 emarginate; anterior angles rounded, not marked; basal angles 

 widely rounded ; lateral margins explanate, slightly rugose- 

 punctate ; median line lightly marked ; a wide depression on 

 each side of base. Elytra nearly twice as wide as prothorax 

 (8-2 X 6 mm.), widest rather behind middle; shoulders rounded; 

 apex wide; strite strongly impressed, seventh not lighter than 

 others ; interstices lightly convex, eighth wider than seventh, 

 ninth narrow on sides, wide towards apex, seriate-punctate, the 

 punctures wide apart in middle; border reflexed; marginal channel 

 wide. 



Length 13, breadth 6 mm. 



Hah. — Mount Barker (Lea, one specimen). 



Genus Platylytron. 



98. P. AMPLlPENNE, Macl.; I.e. Sp. 540. Hah. — Mount Barker 

 (Lea). 



Genus Microferonia. 



I would refer to this genus Lacordairia ancJiomenoides, Casteln. , 

 L. argutoroides, Casteln., L. marginata, Casteln., and Badister 

 anchomenoides, Macl. The episterna of the metasternum vary 

 slightly in length in different species, but are always longer than 

 broad. It may be noted that here the apical joint of the max- 

 illary palps is inserted rather obliquely on the penultimate, 

 suggesting a remote affinity to the Panagfeini ; this is well seen 

 in M. marginata, Casteln. 



99. M. ADELAIDE, Blkb.; I.e. Supp. Sp. 7551. FaJ.— Bridge- 

 town (Lea). 



I have submitted the single example of this species sent by Mr. 

 Lea to Mr. Blackburn's inspection, and he has identified it as 

 M. adelaidce, 



100. M. ciNCTiPENNis, n.sp. 



Subconvex, very finely shagreened ; head small, mandibles 

 widely bifid at apex; labrum triangularly excised, quadrisetose
