Excerpt from A Study in Insect Parasitism: A Consideration of the Parasites of the White-Marked Tussock Moth, With an Account of Their Habits and Interrelations, and With Descriptions of New Species Many observations are recorded which show the prominent part which parasites take in the reduction of an insect which under favor able conditions has exceeded its normal bounds in respect to numbers.
