R. grandis, Maskell. — Mask. S\Z. Trans , 1891, p. 29. 



Adult female dark-red : subglobular, convex ; in length 

 about i in. 



Larvae red : flattish : length £g in., a row of slender spines 

 runs round the margin. 



Hab : In Australia on Acacia longifolia. (Mask). 



A rather showy insect and the largest of the genus, and 

 being naked readily noticed by the collector. Mr. Maskell 

 gives Acacia longifolia as its food plant, his specimens having 

 been furnished to him by Mr. French on roots of that plant 

 in 1 89 1. I have now so often found this insect on Acacia 

 ■implexa and A. decurrens, and on one occasion on Eucalyptus 

 rostrata at Bacchus Marsh that the species is not so restricted 

 in its range of distribution or in its host-plants as is generally 

 supposed. 



In 1891 I sent a Rhizococcus to Mr. Maskell, which he 

 named R. grandis var. spinosicr, Maskell, (N Z. Trans. 1892, p. 

 230,^ and in his letter to me says, " I can only place this insect 

 as a "variety" of grandis at present, though at one time I had 

 almost made up my mind to rank it as specific " For several 

 years I was unable to do any collecting, and unfortunately no 

 further notice has been given of this variety. Early in the 

 present year I sent to Mr. Maskell many specimens, accom- 

 panied by notes, and my belief that it was clearly distinct from 

 R. grandis, Mask. Uufortunately his lamented death prevented 

 his replying to my letter ; however his executors, as I under- 

 stand, have some M S. Coccid notes which will soon be published, 

 and awaiting such I withhold any notes on the species at 

 present, but will deal with it in a future paper.
