482 ON carabidjE from west Australia, 



peduncle on each side of base; a curved linear impression on each 

 side of peduncle (outer basal impression obsolete). Elytra sub- 

 convex (4-2 X 2-7 mm.) ; sides lightly rounded, a little narrowed to 

 shoulders ; strife moderately impressed; interstices not convex, 

 second widest, 3-6 not differing greatly in width at base, lateral 

 interstice becoming convex towards base; basal border arcuate on 

 posterior margin, not dentate at humeral angles; lateral border 

 reflexed. 



Length 6-5-7, breadth 2 -4-2 -7 mm. 



ffab. — Swan River, Rottnest Island, Beverley, Bridgetown 

 (Lea). 



Jffote. — The specimens from Bridgetown are even in size (7 mm.), 

 while those from Swan River, Rottnest Island, and Beverley are 

 smaller, and appear narrower (especially the prothorax); they also 

 have the elytra less strongly striate, and with the external angles 

 of the basal border a little more marked, but I cannot regard 

 them as a different species, though West Australian collectors 

 may ultimately prove them to be so, or at least entitled to rank 

 as a variety. 



91. S. SEXFOVEATUS, Chaud.; I.e. Sp. 905. 



I believe the species described below to be S. ftex/oveatvsy 

 Chaud., and that the original description was founded on an old 

 specimen which had undergone a lengthened immersion in alcohol 

 (such a specimen is in my possession, given to me by Mr. Masters 

 as from King George's Sound). If I am right in my identification 

 of this species, the habitat " Queensland," given by Count de 

 Castelnau, who sent the original specimen to Baron Chaudoir, 

 must have been erroneous. Thinking the original description 

 faulty, as founded on an inferior specimen, I give the following 

 from fresh specimens: — 



Oval, subdepressed ; head small, smooth ; eyes prominent; 

 prothorax Isevigate, subquadrate, much wider across base than 

 apex, elytra striate, interstices depressed, third narrower than 

 fourth ; prosternum margined on base, mesosternal episterna 

 punctate, metasternal episterna elongate. Piceous-black, subiri-
