598 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



The female differs from the male in being larger, even more 

 obscurely coloured, without abdominal carinas, and with very short 

 spurs to posterior tibife, the elytral strife less distinct. Length: 

 ^ 3i-4|, width 2-2|; 9 5h and 2J mm. 



Hab. — Tamworth. 



The above species differs from S. maculatus, Blackb., in being 

 much more elongate, less convex, coloured in a different style, 

 the elytral strife more distinct, kc.

 of prothorax and scutellum; meso- and metasternum piceous, 

 femora dark reddish-piceous, tibiae and tarsi dark red, abdominal 

 segments reddish-testaceous, basal joints of antennae red. Clothed 

 with short ashen pubescence, much shorter and denser beneath.

At once distinguished from S. macidatvs and the preceding- 

 species by the total absence of elytral striation; in shape it is 

 intermediate between the two; from the following species {also 

 without striation) it is distinguished by its larger size, less convex 

 form, sparser puncturation, different colour, etc.
