The April number of the Entomologist contains a commnunication from my esteemed friend Mr. S. H. Scudder, with reference to the yellow male variety of this species. In it he asks several questions which I shall endeavour to answer, adding some other particulars to make my notes as complete as possible.

I think that entomologists will agree with me in considering P. rapæas one of the most interesting insects existing on this continent, not only with refercnce to its destructive habits, but also on account of its recent introduction and rapid dissemination over the country.

Brush dark brown, apical joint pale yellowish. Head, thorax, and fore wings pale yellow, faintly tinged with pink, and minutely dusted with fuscous, ans with a fuscous streak on the base of the costa. Head and thorax slightly iridescent, wings scarcely so; posterior wings a little paler. Under surface and legs pale yellowish, sparsely dusted with fuscous. Alar ex. 5/8, inch. Names for Mr. C. V. Riley, State Entomologist of Missouri. Kentucky. Larva unknown. Also in the collection of Mr. Wm. Saunders, London, Ont.

I give here a list of those of the Entomological writings of my late esteemed friend, Mr. Coleman T. Robinson, that have been published under his sole signature.

These recommended themselves to the attention of the student by the conscientious statement and adequate illustration of the different species they discuss. The were all writtent subsequent to Mr. Robinson's return in 1868, from a journey to England and Continental Europe, during the prosecution of which a representative collection of European Lepidoptera was acquired, and especial attention was paid to the smaller moths.
