MONOMORIUM NITIDUM Sm. 



Described by Smith as a Tetramorium. Common at 

 Greymouth ; and, according to Forel, at Mount Cook, on 

 the Island of Timaru, at an elevation of 2,540 feet. 



HUBERTIA STRIATA Sm. 



This was also erroneously referred to Tetramorium. It

For an interesting description of the habits of the 

 above-mentioned ants, as observed at Ashburton, the 

 reader is referred to a paper " On the origin of Ants' 

 Nests," by Mr. W. W. Smith in Entom. Mon. Mag., March, 

 1892, pp. 60-65.* The nests are formed under stones 

 partly buried in the sandy soil, on the terraces of the river 

 and in stony places on the plains. 



In the nests of the ants are found sundry inquilines. 

 There are two species of Homoptera a species of Ripersia 

 and Dactylopius poce Maskell, both feeding on the roots 

 of the grasses among which the ants' nests are placed ; 

 a beetle, Diarthrocera formicoephiia Brown, an isopod, 

 Platyarthrus^ and some mites. It is noteworthy that the 

 coccid genus, Ripersia, and the crustacean, Platyarthrus, 

 are found inhabiting ants' nests in Europe. 



PONERA CASTANEA Sm. 



Several examples.
