3Jmm.), a little wider than the prothorax, rather flat, the sides 

 sloping gently from the 6th stria ; striee shallow, finely punc- 

 tate, the abbreviated stria longer and less oblique than usual in 

 the genus ; interstices equal, not convex, 9th punctate as usual. 

 Segments of the abdomen smooth. Metasternal episterna with a 

 few line punctures. 



Long. 10, lat. 3| mm. 



Hah. — South Australia. 



I have six specimens, all of which T believe to be females j the 

 anterior tarsi are as in tlie females of all other species of Sarticus 

 I have seen, not being dilatate, but I cannot discern more than 

 one setigerous puncture on each side of the anus in any of my 

 specimens ; in every other species I know the female has two 

 anal punctures on each side. 



The synonymy given above is on the authority of de Chaudoir."^ 



Sarticus ischnus. 



Feronia {Sferopus) eleyantala, Casteln., Trans. E-oy. Soc. Vic- 

 toria, 1867, VIIL p. 224. 



The name Feronia (Sai^ticus) ischna was proposed by de Chaudoir 

 (Bull. Mosc. 1878, LTII. p. 68) for Feronia {Ster opus) elegantula, 

 Casteln., de Castelnau's name having been previously used in the 

 genus Feronia. 



This species is allied to S. cydoderus, Chaud., but is of much 

 more elougate form, and has the prothorax hardly transverse. 

 The following is de Castelnau's original description: "Length, 

 4 lines; very much like Waterhousei [cydoderus, Chaud.], but of 

 a still more slender and elegant form ; thorax much narrower 

 behind ; elytra more elongated and oval ; three punctiform im- 

 pressions on the interval between the second and third striae." 



To this I would add the following measurements taken from 

 specimens in the Australian Museum, Sydney. 



Length 8 mm. ; breadth 2| mm. Prothorax, length 2 mm. ; 

 breadth 2 J mm. Elytra, length 5 mm. ; breadth 2 J mm.
