species, witlioiit the trouble of a close examination, is to count 

 the punctures in the lateral margins of the elytra near the 

 humeral angles. In S. rotundijpennis there are eleven or twelve 

 close uninterrupted punctures, in 8. MacLeayi there are eight 

 or nine, while S. intermedius has but six, or at the most seven. 



In 8. Silenus and 8. latipennis, the only species from the 

 West Coast I have seen, the lateral margins of the elytra are 

 closely punctured all round. 



The genus Scarif.es is the next, and I find that I have made a 

 very great mistake in my first paper on the 8caritidce, in classing 

 this genus among those with toothed maxillae. 



I find, as far as the Australian species are concerned, that the 

 inner lobes of the maxillae, though not so broadly rounded as in 

 the genus Carenum, are still round at the apex and without a 

 terminal tooth ; and I find further, in page 82 of vol. I., of the 

 Arcana Entomologica, that Mr. Westwood states he has seen 

 Latreille's dissections of the Scaritidce, and that the maxilla of 

 all are obtuse at the tip. 



My mistake arose from my trusting too implicitly to the 

 description of Scarites given in Lacordaire's " Genera des Coleop- 

 teres," vol. I., page 195, where that author states : " Machoires 

 arquees et aigues au bout." 



I find I have five species to describe, 



1. — SCAEITBS APPROXIMATTJS. 



Niger nitidus, capite antice rugoso, thorace subquadrato medio 

 tenuiter canaliculate basi utrinque longitudinaliter im- 

 presso, corpore subcylindrico, elytris ad suturam subelevatis 

 apice utrinque bipunctatis.

 The head is marked in all the species I have seen with two 

 parallel longitudinal grooves, commencing about the middle 

 of the forehead, and extending nearly to the clypeus, where they 

 terminate in a transverse groove, which extends almost from 

 side to side. In the present species the transverse groove is 

 much corrugated towards each side. The thorax is rather longer
