252 THE GENERA AND SPECIES OF AMYCTERID^, 



This fine species which I received from Mr. Waterhouse, 

 of Adelaide, differs from S. Adelaidce, and all the species hitherto 

 described, chiefly in the size of the strong obtusely conical 

 glossy tubercles on the elytra. It differs besides in having the 

 tubercles on the thorax ovate and large. The punctures on 

 the elytra also are each accompanied by a more prominent 

 granule than in the above-named species. The apex of the 

 elytra is not mucronate, and scarcely dehiscent. The scales 

 are not very thick on the upper surface, and, on the under 

 surface, are very thin. 



14. — SCLERORINUS InTERIORIS. 



Oblongo-ellipticus latus niger cinereo-squamosus, thorace crebre 

 tuberculato tuberculis nitidis ovatis, elytris seriatim granu- 

 latis rude punctatis interstitio 1""° quadrituberculato 2'"*° 

 remote seriatim tuberculato 3*'° unituberculato 4'° et 5"'° 

 crebre seriatim tuberculatis tuberculis omnibus validis 

 conicis nitidis setigeris apice dehiscentibus obtuse sub- 

 mucronatis. 



Long. 10 lin., lat. 4^ lin.

This species very much resembles the last. It is, however, 

 broader and flatter, and differs in having a tubercle on the 

 third interstice of the elytra, and in having the apex more 

 dehiscent and obtusely pointed. The scales also on the elytra 

 seem thicker, though they do not touch the tubercles, which 

 are very black and brilliant. 



I am indebted to Dr. Howitt, of Melbourne, for a specimen 

 of this very fine insect. 



15. — SCLERORINUS StEWARTII. 



Oblongo-ellipticus niger cinereo-squamosus, thorace subremote 

 tuberculato tuberculis parvis hemispha^ricis nitidis seti- 

 geris lateribus medio ampliato, elytris albido-vittatis se- 

 riatim punctatis granulatis interstitiis remote tuberculatis 

 tuberculis parvis subelongatis nitidis setigeris setis pallidis 

 apice rotundatis crenatis.
