Species — i. Hopei, While, loc cit., p. 508, tab. 2, fig. 2, 9 ( Sitarida). 

 New Holland. 



Large species, black, head convex, strongly rounded in front, coarsely 

 sculptured, thorax subtrigonate, sides slightly rounded, coarsely punctured, 

 legs robust, tarsi short. 



2. flavicornis, Pasc, ioc cii., p. 48, tab. 2, fig. 5, <^ {Goetyines), Port 



. Stephens. 



Smaller than preceding, pale fulvous, head and thorax more finely 

 punctured, the latter with a cruciform impression on disk. 



3. pidipes, Blackburn, Trans. Roy. Soc. S. Austral, XXIII, 1899, p. 



69, (^ {Goetymes)^ Melbourne. 

 Half the length of Hopei, black, head and thorax closely and rather 

 strongly punctulate, the latter transverse, canaliculate, elytra light brown, 

 tibife and tarsi yellow. 



4. i]ii7i07\ Champion, Trans. Ent. Soc. Lond., 1895, p. 274, tab. 6, 



fig. II, 'i^ ( Sitarida), Hobart (Tasmania). 



Much smaller than preceding, head and thorax closely punctate (but 

 with vertex sparsely so, and occiput almost smooth), vertex broadly and 

 abruptly raised, subtruncate at summit, thorax strongly transverse, with 

 two smooth transverse tubercular elevations on disk \ legs very slender. 



The following artificial table, based on the thoracic characters, may 

 aid in separating the above forms : 



A. Thorax canaliculate. 



Thorax transverse, coarsely and rather strongly 



punctulate $ pidipes. 



AA. Thorax not canaliculate. 



a. Thorax subtrigonate, sides slightly rounded. 



a. Thorax coarsely punctured 9 Hapei. 



a.a. Thorax more finely punctured, and with cruciform 



impression on disk c^ flavicornis, 



aa. Thorax strongly transverse. 



Thorax closely punctate, and with two smooth transverse 

 tubercular elevations on disk % mi?ior. 



4. Champion gives his insect as a male, but judging- from his description 

 and figure (I have not seen his type), I think this must be a mistake. If his 

 determination of the sex should prove to be correct, it would necessitate the 

 erection of a new genus.
