possession, it will be useful to compare it with .S'. hahitans, 81., to 

 which it is more nearly allied than I formerly thought. 



Dorsal strife of elytra crenulate ; prosternum with apex 

 bordered; mesosternal episterna punctate, metasternal episterna 

 with a few punctures: legs long, femora narrow. Differs from S. 

 habiians {^)hy eyes less convex; prothorax narrower(3'3 x 3-8mm.), 

 widest a little before middle; evidently more narrowed to base 

 (2 'To mm. between posterior marginal punctures), border narrower; 

 el3''tral striae narrower and more finely crenulate; three apical 

 ventral segments w^ith a row of rather strong punctures extend- 

 ing across each of them near anterior margin; femora less stout. 

 Length 13-3, breadth 4*75 mm. 



Hab. — N.S. W. : Coonabarabran (Sloane). 



Sarticus cooki, n.sp. 



Oval, convex. Head large (2*4 mm. across eyes); prothorax 

 strongly rounded on sides; elytra oval, convex, striae crenulate, 

 interstices lightly convex on disc, depressed on apical and lateral 

 declivities, 3rd tripunctate, tarsi with 5th joint spinulose beneath. 

 Black; elytra bluish, nitid in ^J, opaque in 9. 



(J. Head convex; eyes large, prominent. Prothorax broader 

 than long (3-1 x 3-7 mm.), convex; sides strongly rounded; border 

 reflexed, moderately wide on anterior part of sides, becoming 

 wider backwards from anterior marginal puncture, explanate and 

 circumscribing the lateral basal fovete towards base, narrow and 

 entire on apex; middle of base not bordered; median line ending 

 in a punctiform impression at posterior extremity. Elytra oval 

 (7*2 X 4-6 mm.), convex; striae shallow, rather finely crenulate, 

 the crenulation almost obsolete on apical declivity, 7th stria 

 lightly impressed, 8th lightly impressed, interrupted by the 

 punctures of 9th interstice, hardly crenulate between these punc- 

 tures, 7th, 8th and 9th interstices dej)ressed (not at all convex) 

 on basal half; lateral apical sinuosities weak — short but distinct. 

 Prosternum bordered on apex ; mesosternum deeply concave 

 between coxae ; concavity of episterna finely punctate ; meta- 

 sternum with outer marginal border feebly developed or obso-
