This paper on the insects of the genus Trogus (family Ichneumonidae ) found in America, north of Mexico is the result of work done at the Massachusetts Agricultural College under the guidance of Dr. H. T. Fernald and forms a portion of a thesis for the degree of Master of Science. I have attempted to bring together and systematize the works previously published and have added the descriptions of four new species.
