MISS EMBLETON ON CERATAPHIS LATANIiE. 05 



' Gardeners' Chronicle,' where Westwood's figures are repro- 

 duced still under the name of Asterolecanium orcliidearum. 

 Mr. Lynch, of the Cambridge Botanic Garden, who is interested 

 in the insect as being an inhabitant of the orchid-bouse, brought 

 to my notice this article, which led to my finding Westwood's 

 original description. 



Thus it is seen that the creature has appeared under the names 

 of Coccus ? latanice, Boisd., Boisduvalia latani(S^ Sign., Asterole- 

 canium orcliidearum^ Weatw., Cerataphis latanice^ Licht., Cerato- 

 vacuna brasiliensis, Hemp. Of these the name of Cerataphis

In turning to the natural history of this interesting species it 

 is, perhaps, not out of place to briefly summarize the facts that 

 are known at present. The species occurs frequently in orchid- 

 houses in Britain, as the apterous parthenogenetic form; and for
