5. Larger, more ovate; convex beneath. 



Dimensions : $, 13 x 4-5; 9, 14-5x6 mm. 



Hab. — N.S.VV.: Wagga, Deniliquin, Mulwala - Vic: Birchip. 

 Type in Macleay Museum. Described from specimens in my 

 own collection. 



Specimens from Birchip, in my own collection, vary somewhat 

 from the above description. The male has the sides of the 

 median area slightly raised at base; and the median area slightly 

 depressed, and with a longitudinal, impressed line in the centre; 

 the third interstice is biseriately granulate in the middle. The 

 female has the sides of the median area more definitely raised, 

 the centre not being depressed; the elytra are tuberculate in 

 single series. I have grave doubts as to whether this species 

 should be allowed to remain in Sclerorinus; the median area is 

 not definitely carinate, though it appears through the clothing 

 as a laevigate line; the internal ridges are not traceable, unless 

 the feeble elevations, at the base of the median area, in the 

 Birchip specimens, represent such. The undersurface, moreover, 

 is not channelled at the apex, as in one Section of Sclerorinus; 

 nor does it possess a hirsute, median vitta, as in the other Section. 

 On the other hand, it appears related to no species of Talaurinus 

 known to me. For the present, I prefer to regard it as an 

 aberrant species of Sclerori^ius. S. alternus was founded on an 

 abraded specimen of the same species.
