This may be clistiDguished from other Australian species of 

 the Pisonitus group by the black abdomen and red legs, P. ig- 

 navum being wholly black, and the other species of the group 

 having the abdomen and antennae more or less red.

15. PisoN viROSUM Turn. 



Fison virosum Turn. Proc. Zool. Soc. London,, p. 513 (1908), 5 • 

 This is a larger and more robust species than rujicornis, and 

 may also be distinguished by the greater distance between the 

 eyes on the clypeus a.nd by the golden pubescence of the clypeus 

 a,nd front. The abdomen is ferruginous, except at the extreme 

 base.

The type has the abdomen largely shaded with black, but in 

 many specimens it is wholly ferruginous. In both this species 

 and virosum there is a rather indistinct impressed transverse 

 line behind the posterior ocelli, which seems to be characteristic 

 of the Pisonitus group.

17. PisoN PRiscuM Turn. 



Piswi insidare Sm. st. prisGiivi Turn. Proc. Zool. Soc. London, 

 p. 510 (1908), $ . 



The diffei"ence in the distance between the eyes on the vertex 

 in insidaris and priscum is quite distinct, though not very great ; 

 the sulcus on the median segment is much more distinct in 

 insidaris, and the second dorsal segment is more depressed at the 

 base. The clypeus is also slightly different. Until a long series 

 from different localities is available, it may be best to treat the 

 two forms as distinct species. In priscum the second ventral 

 segment is not as highly polished as in festivics smd fenestratus, but 

 there are no distinct punctures. The insect is entirely black, 

 except on the apical margins of the ventral segments, which are 

 brownish.
