The following is an illustrated discussion of pupal abdominal characters observed in British Columbia species of Dioryctria, a genus containing some of the most economically important cone-feeding and wood-boring Lepidoptera. Species examined and referred to herein are: cambiicola (Dyar), zimmermani (Grote), abietivorella (Grote), auranticella (Grote), rossi Munroe, reniculella (Grote), and pseudotsugella Munroe. Dioryctria reniculella and pseudotsugella are defoliators, but they may occasionally feed on cones.
