282 ON A NEW AUSTRALIAN COCCID. 



or the second stage. The former, in all probability, will not greatly 

 differ from those of other Monophlebids, except perhaps in colour. 

 No writer that I know of has described the second female state of 

 any foreign Monophlebid except Icerya and, doubtfully, Drosicha, 

 and yet this would be exceedingly interesting. In the case of the 

 New Zealand species of Ccelostoma, as far as they are known, 

 the second stage is found in thick, waxy cases or " tests," either 

 above or under ground. It is likely that the same would occur 

 with C. ausirale, though the variation of Coccids are so curious 

 that nothing can be predicated certainly on the point. As this is 

 the first species of the genus found outside New Zealand, I have 

 thought it best to attach to it the name australe more especially 

 as, from its active habit in the adult state and from the absence of 

 a rostrum, it would not be easy to ascribe to it any particular 

 food-plant.
