508 STUDIES IN AUSTRALIAN ENTOMOLOGY, 



behind, in the 8th interstice being broader than the 9th, and in 

 the 8th stria not being thickly set with punctures. 



Length 1J:-15 ; breadth 5 mm. 



Hah. — South Australia. 



I have only had the opportunity of examining three specimens 

 of S. civilis ; of these two had the mesosternal espisterna distinctly 

 punctate, while the metasternal espisterna in none of them pre- 

 sented more than two punctures; judging from the latter feature 

 alone it would almost be better placed with group I. of my table. 



Sarticus rockhamptonensis. 



Feronia (^Steropus) rockhamptonensis^ Casteln., Trans. Roy. Soc. 

 Victoria, 1865, VIII. p. 223. 



This species has been united with S. ohesulus by de Chaudoir,"^ 

 but I have a female specimen from the Rockhampton district 

 which appears to me distinct from S. ohesulus, while it agrees 

 with de Castelnau's description of S. rockhamptonensis. 



In general appearance like S. obesula, but differing from it in 

 having the prothorax less transverse ; in the elytra of the female 

 being duller, with the strife shallow and very finely punctate, and 

 with the interstices flat ; in all the segments of the abdomen 

 being closely and rather roughly punctate ; and in the meso- 

 sternal and metasternal episterna being punctate. 



Length 16 ; breadth 6 mm. 



Hah. — Rockhampton district, Queensland, a single female 

 specimen in my collection. 



Sarticus habitans, sp.nov. 



Niger, nitidus ; prothorace antice posticeque truncate, cana- 

 liculato, ad angulos posticos utrinque impresso ; lateribus rotun- 

 datis marginatis ; elytris ovatis, tenue marginatis, fortiter 

 striate - punctulatis, interstitiis convexis, 3° tribus punctis 

 impresso, lateribus subparallelis ; abdominis segmentis ad latera 

 subtiliter punctulatis. 



Long. 13-15 mm. ; lat. 4J-5J mm.
