small, are acute and quite distinct to the naked eye. On one 

 specimen the base of the head (behind the eyes) is exposed, 

 and is seen to be densely covered with minute granules. A 

 specimen of this species was in the Blackburn collection as 

 ingens (see the following note). 



Helaeus ingens, Blackb. 



This species was described as from the McDonnell Ranges, 

 and there are two co-types in the Blackburn collection. In the 

 original description the elytra were noted as "obsoletissime 

 quadrieostato (costa externa quam ceterae paulo fortiori et 

 granulis conieis sat validis annata)." Subsequently, when 

 dealing with the beetles of the Horn expedition, Blackburn 

 identified three Tempe Downs specimens as belonging to 

 ingens; two of these are presumably in the National (Mel- 

 bourne) Museum, the third is before me and is not ingens (it 

 is entirely without the sublateral row of granules on each 

 elytron) but the species described above as waitei.
