Mr* Grant Allen has advocated tlie view of a correlation between tlie colours of animals 

 and the food on which they feed, " Where bright blossoms are common insects are brilliant, 

 while where most blossoms are inconspicuous most insects are dingy."* "In short, the 

 immense majority of animals which do not feed on bright- coloured food are of plain hues, &c." j 

 Mr. Allen has greatly relied on the brilliancy of flower-frequenting butterflies in support of his 

 theory, which might also have been assisted by a reference to the generally sombre-hued 

 Snttfri.nn, whose hume and sustenance are the wind -fertilised grasses, with their obscure anil 

 degenerate Mowers. J 



Seven genera only can at present be included in this fauna, which is doubtless an insufficient 

 enumeration,

$ I here use the term u ocelli" for brevity, preferriujr that of "ocellateil spots." as elsewhere applied in the text. 

 Although tin lirst term is used by many excellent kpblopterists, still it bus an earlier aod distinct entomological definition, 

 especially in Ithynrhota.
