The head capsule with attached mouthparts was first removed from the body by a cut made with a fine forceps around the edges of the occipital foramen.The maxillae and labium as a unit were removed from the head capsule.The head was sketched under this condition from dorsal and ventral sides.Then the mandibles with attached tendons were removed from the head capsule. Mouthparts and skins were mounted on microscopic slides for detailed examinations(1 00×or 1 50×).
