new genus. In this particular, however, the species placed under 

 the new uame are certainly united with A. Forttmmi, Bostochii, 

 and Odeivahnii, and in a less decided way with A. Curvicornis. I 

 prefer, therefore, for the present, to place the first of the species 

 which I am about to describe under the old genus ; although from 

 its singular resemblance to A. Braziliensis, it may eventually find 

 itself under the new genus Fustiger. 



These insects are rare in New South Wales. But their 

 small size, and particularly the ferocity of the ants, under whose 

 protection they live, may in some measure account for the 

 infrequency of their capture. I have been able, however, to add 

 four species to our Colonial Fauna. A. angusticollis occurs in 

 ants' nests, at Paramatta, and in the Liverpool Plains. A. 

 setipes was captured by my son, Mr. R. King, at Goono Goono, 

 in the Liverpool Plains district — hardly differing from specimens 

 in my cabinet from Gawler, South Australia. A. curvicornis is 

 frequently captured at Liverpool, in the nest of the small black 

 ant — and differs only in its somewhat smaller size from the 

 description given by Westwood, (Loc. cit.) of Melbourne speci- 

 mens. The fourth species, A. regius (niihi) is as far as is yet 

 known peculiar to Liverpool. Mr. Masters has also captured a 

 species in debris, after a flood, at Rope's Creek, near Penrith, 

 which I have described as A. hrevicejps. 



ArTICERUS REGIUS.
