Maskell. — On Coccidas. 293 



I imagine that both these forms are new ; aiid, as 

 remarked above, the occurrence of members of this genus 

 seemingly only on birds in and around New Zealand is some- 

 what interesting.

The following paper contains, perhaps, fewer "novelties" 

 than some of my former ones, but such species as Lecanium 

 mirificum, Inglisia fossilis, or Splicsrococcus socialis are as in- 

 teresting as any yet known ; and I think that if my identifica- 

 tion of Monophlcbus huryneisteri is correct, as I believe it is, 

 we have here a valuable addition to our knowledge of Coccids. 

 I am greatly indebted to Messrs. Koebele, French, and 

 Lea for the numerous specimens which they have sent me. 

 Those from Mr. Koebele are especially interesting as showing 

 the wide range of many species already known — e.g., Asjndio- 

 tus ficiis and A. destructor, Parlatoria zizyphi, Eriochiton 

 cajani, Icerya seychellarum, &c. Some of these, such as E. 

 cajani, Geroplastes rubens, are doubtless indigenous in many 

 lands; others, such as A. ficiis or P. zizyphi, have probably 

 been introduced by the modern extension of traffic. Fifteen 

 ■of the species mentioned in this paper have been received from 

 Mr. Koebele, from China, Japan, and adjacent countries : of 

 these, I find that only three can be considered as new ; but, in 

 fact, the collection of Coccids in the extreme oriental region is
