702 REVISION OF THE AMYCTERIDES, iv., 



the anterior tarsi are simple. Dimensions: ^, 19 x 7; prothorax 

 5x6; elytra 10x7 mm. 



Bab. — South Australia. 



The species presents considerable variation in size, and in the 

 number and position of the elytral tubercles. On the third 

 interstice, the tubercles are sometimes fairly closely set, and 

 sometimes rather widely separated and fewer in number; the two 

 sides of the elytra sometimes differ in this respect. S. nodulosus 

 and S. divaricatiis have already been sunk as Synonyms by Mr. 

 Lea, and I can see nothing in the types to warrant their separa- 

 tion. 



ScLERORiNUS Waterhousei Macl. 



Macleay, loc. cit.. p.251; S. interioris Macl., loc. cit., p. 252; 

 Lea, loc. cit., p. 11 2. 



^. Large, elongate, relatively broad, subparallel. Black ; 

 densely clothed with brownish subpubescence, the tubercles 

 nitid, not clothed; ventral maculse small. 



Head and rostrum as in S. Adelaide. Prothorax (5 x 6- 25mm.) 

 widest in front of middle, much as in S. Adelaides, tubercles, if 

 anything, slightly larger, less elongate, with larger ones along 

 the subapical impression. Elytra (12x7 mm.) broad, apex not 

 produced, base deepl}^ emarginate, humeri prominent; seriate 

 punctures small, open, intrastrial granules rather more pro- 

 minent; tubercles larger, the apical and lateral ones more conical; 

 second with four; third with a subcontinuous row of eleven from 

 base almost to apex; fourth with none; fifth with a continuous 

 row of sixteen, slightly smaller, closely placed, almost imbricate, 

 conical tubercles; sixth with a continuous row of eleven, slightly 

 larger than on the fifth, conical, outwardly directed. Apical 

 ventral channel rather narrow, in type obscured by dirt. Inter- 

 mediate tibiae slightly emarginate; anterior tarsi simple. 



^. Larger, more ovate, the apex more produced. Prothorax 

 (6x7 mm.) with tubercles larger than in S. Adelaides, elongate 

 near middle, rounded towards the sides. Elytra (14 x 9 mm.) 

 broad, apex moderately produced; tubercles noticeably larger 

 than in S. Adelaides, tubercle-index 2-3, 9-12, 0, 17, 15. Apical
