tlie seventh stria, at irregular distances apart, and closest towards 

 the apex, and three or four also near the apex, about the line of 

 the third stria ; the three teeth on the fore tibiae are blunt ; the 

 tooth on the intermediate tibise is large, flattened laterally, and 

 rounded at the apex. 



Genus Scarites, Fab. (Syst. El. 1, p. 24i).) 



This genus, the most numerous of the family in other parts of 

 the world, (upwards of one hundred species having been de- 

 scribed,) has not, I believe, until now, been clearly proved to be an 

 Australian genus, Mr. Westwood, certainly, (Arc. Ent. 1, p. 88), 

 describes an Insect from Van Diemen's Land, as 8c. sculptilis ; but 

 as the head of his specimen was wanting, it is difficult to deter- 

 mine on what grounds he could have jiidged it to be a true 

 Scarites. 



This is the only one of the five genera mentioned in this 

 Paper, which is not exclusively Australian. It may be readily 

 distinguished from the two genera last described, by its pointed 

 maxilliB, large size of basal joint of antennae and winged body ; 

 and from the two following genera, by its strongly toothed trans- 

 versely striated mandibles, and general form.

 The whole body is black and shining, with the exception of 

 the antennge, palpi and tarsi, which- are pitchy ; the mandibles are 

 coarsely striated : the head is smooth, the frontal impressions do 

 not reach the occiput. The thorax is slightly broader than the 

 head and about as broad as long ; the apex is almost truncate, the 

 basal angles are round, the base itself is slightl}- emarginated ;
