826 CARABIDiE FROM DORRIGO, N.S.W., 



inner lobe not hooked at apex. Labial palpi with penultimate- 

 joint bisetose in front. Prothorax much wider than head, a trifle 

 longer than broad (3'2 x 3-15 mm.); sides lightly rounded on 

 anterior three-fourths, strongly sinuate near base; anterior margin 

 truncate; anterior angles obtuse, but a little marked; base 

 truncate, angles sharply rectangular; lateral basal impressions- 

 shallow; spaces between each lateral basal impression and lateral 

 channel narrow, convex; two marginal setse on each side, anterior 

 at anterior third, posterior in lateral channel a little before basal 

 angle Elytra oval, convex, much wider than prothorax 

 (6'1 X 4-2 mm.); sides rounded; base truncate; humeral angles 

 subdentiform; apex lightly sinuate on each side; first stria very 

 lightly impressed, not reaching base; striae 2-4 fine but strongly 

 impressed, fifth strongly impressed on apical declivity, becoming 

 obsolete before reaching middle of elytra; first interstice 

 narrow, the others wider, equal, hardly at all convex; a 

 row of punctures along lateral channel. Length 9-12, breadth' 

 3-2-4-2mm. 



llab. — L)orrigo. 



This species is readily distinguished from the other three 

 described species of the genus, by having the prothorax less 

 strongl}-^ rounded on the sides, lateral basal impressions much 

 shallower; elytra with striae much shallower, interstices hardly 

 at all convex. Specimens of two distinct sizes occurred together 

 at Dorrigo, in the brush; the larger 12mm., the smaller 9mm. in 

 length. Four specimens are before me; of these two of the larger 

 size and one of the smaller are females, the other specimen being 

 a male, 9 mm. in length. 



Note. — Having specimens of the four species of Meonis before 

 me, it seems advisable to tabulate them as under : — 



Elytra with disc deeply 5-striate. (Prothorax broader 



than long, 3-25x3'5mm.) M. niger Cast. 



Elytra 4-striate on disc, 5-striate on apical declivity. 



Striag lightly impressed; prothorax lightly rounded 



on sides M. angusiicollisSL
