The article on Diaspis amygdali Tryon, by Professor Webster, in the April issue of this magazine, has left me with the impression that the introduction of this insect to several widely separated sections of the United States has not aroused the apprehension among American entomologists that the advent of a pest of its importance justifies. The quotation from Mr. Tryon's letter to the effect that the insect is neither widely distribued nor destructive in Queensland is too reassuring. It constrains me to emphasize the fact that the species is a highly injurious one in Cape Colony. A brief account of its occurrence here may not be uninteresting.
