ventral segment with a feeble linear impression. Dimensions: 

 ^19x7; 9 22x9 mm. 



Hab. — South Australia. Type in Macleay Museum. 



There are two specimens, sexes, under this label in the Macleay 

 Museum, but the female appears to have been the actual tvpe. 

 Apart from the larger size in the female, and the larger, more 

 conical, elytra] tubercles, I can find nothing to separate this 

 species from 6'. Adelaidce. It is convenient, however, to retain 

 this name for the larger form, though I much doubt if the species 

 are really distinct. S. interioris is certainh^ conspecific, as has 

 already been pointed out by Mr. Lea.

(J. Type, >S'. vittatus Macl. — Elongate subparallel, comparatively 

 broad. Densely clothed with brown, trivittate and variegate 

 with white, vittse distinct on prothorax, on elytra forming a 

 broad sublateral vitta, third interstice feebly maculate with 

 white; setae dark. 



Head continuous with rostrum, external ridges subparallel, 

 median carina distinct, extending up head, sublateral sulci 

 shallow, foveiform at base. Prothorax (5x6 mm.) widest in 

 front of middle, ocular lobes prominent; subapical constriction 

 indefinite except at sides, median line marked by vitta hardly 

 impressed ; disc with tubercles distinct, somewhat depressed, 

 elongate, irregular, at sides more rounded. Elytra (12x7 mm.) 

 little dilatate, almost parallel-sided to before declivity, base 

 arcuate, humeri marked. Disc with regular rows of small fovei- 

 form punctures, the intervening ridges setigerous, hardly granu- 

 late; tubercles small, subconical, larger nearer declivity, and 

 more, though not greatly prominent, partially concealed by 

 clothing; tubercular index 2, 14, 0, 23, 15; on third interstice, 

 more or less continuous, becoming progressively larger posteriorly; 

 on fifth and sixth, much smaller and with serrate appearance. 

 Fifth segment with median channel, tubercles moderately close
