The ootheca of Lamproblatta albipalpus Hebard is described in detail. The seam is tall, thinly attached to the egg case, and forms a common aeration chamber. Aeration of the eggs occurs through spongy bodies which penetrate the arched midline of the seam floor. The outside walls are covered with small flanges which curve upward from the base. The chorion pattern is irregular and non-symmetrical; calcium oxalate crystals are not visible.
