NOTES ON APHIDES [PDF]

open access: yesThe Canadian Entomologist, 1873
The following notes were suggested by “Observations,” &c" on Aphides in The Canadian Entomologist for July, 1873. The species noticed on Rumex crispus seems to have very much resemblance to A rumicis of Europe; some other species of N. America do not differ from those of Europe, but have been probably introduced by means of shipping. With regard to
