Rostrum hardly excavate; the median carina narrow, raised, 

 running on to head; lateral ridges subparallel; sublateral sulci 

 broad, slightly depressed at base only. Head and rostrum in 

 the same plane above. Prothorax (4x5-5 mm.) subtruncate 

 above, with moderately prominent ocular lobes; disc with elongate, 

 semi-obliterated granules, irregularly arranged in longitudinal 

 lines, the setae arising from the posterior end of each granule. 

 Elytra (12x7-5 mm.) gently narrowed to apex, which is much 

 produced and bimucronate; seriate punctures small, obscured by 

 clothing, set in irregular wavy lines, subtended by small granuJes. 

 Interstices with small tubercles or granules, elongate, narrow, 

 forming rather obsolete costse at base; beyond the middle, the 

 tubercles small, rounded, isolated; fourth with one or two only, 

 about middle; sixth with tubercles closer, giving interstice a 

 serrate appearance. Beneath, gently convex; the apical segment 

 somewhat flattened, with a faint, median, impresssd line, deeper 

 at extreme apex, the apical margin, as viewed on edge, strongly 

 bisinuate. Dimensions: <^, 18x7-5 mm. 



ffab. — Victoria. 



The above description was drawn up from the type in the 

 Macleay Museum. Though in general appearance close to S. 

 tristis, I have no doubt that it is distinct on account of the 

 difference in the ventral apical segment in the female. In *S^. 

 tristis, this shows a small tubercle on either side of the median 

 impression near the apex; in S. ohliteratus, these are not present; 

 moreover, in *S'. tristis, the apical margin is straight, not strongly 

 bisinuate as in S, ohliteratus Macl. 



Unfortunately, I have never been able to obtain a pair, of 

 which the female was absolutely identical with S. ohliteratus. 

 Two species approach it closely, however; one is S. inornatus, 

 which has an even more obliterate- sculpture; the other is from 

 the Victorian Alps, and is more strongly sculptured, but is 

 variable in this respect. Provisionally, I would regard this 

 latter species as *S^. ohliteratus. The male may be readily dis- 

 tinguished from S. tristis, S. sordidus, and S. inornatus by the 

 anterior tarsal joints, not asymmetrically dilatate on the inner 

 side.
