 and elytra with greyish- white along lower border; sides of sternal 

 and abdominal segments clothed with greyish- white; median vitta 

 reddish-brown. 



Head and rostrum in same plane above; external, rostral ridges 

 subparailel, extending on to head; median carina narrow, little 

 raised, showing as a fine, l?evigate line through clothing; sub- 

 lateral sulci moderately broad, basal foveie concealed by clothing. 

 Prothorax (4 x 5 mm.) subdilatate on sides; ocular lobes moder- 

 ately prominent; subapical impression rather indefinite, median 

 line slightly impressed; granules small, slightly larger than in S. 

 sublineatus, and rather more closely set, but not contiguous; 

 sides with smaller granules. Elytra (12x7 mm.) broader and 

 more rounded on the sides than in S. sublineatus; base gently 

 emarginate, humeral angles noduliform; seriate punctures shallow, 

 indefinite, intrastrial granules moderately prominent, but con- 

 <*.ealed by clothing: interstices tuberculate, tubercles small, about 

 the same in size and arrangement as in S. sublineatus; second 

 with a few isolated tubercles; third with a continuous row of 

 about fifteen, becoming more spaced-out posteriorly, and extend- 

 ing down declivity; fourth with a few isolated tubercles; fifth 

 with humeral tubercle followed by three or four smaller ones, and 

 then by a row of granules; sixth with a moderately closely-set 

 row of tubercles, not reaching base. Sides with interstices set 

 with depressed, granuliform tubercles. Undersurface as in iS. 

 sublineatus. Anterior femora feebly ridged beneath; tibire not
