Natural prey.—Cockroaches, U.S.A. (Felt, 1909; Back, 1947; Auerbach, 1951; Crabill, 1952; and others): This predator-prey relationship seems to be based on good circumstantial evidence (Crabill, personal communication, 1953).
Experimental prey.—Blattella germanica, newly hatched nymphs and adult female, U.S.A. (Snodgrass, 1930; Roth and Willis, unpublished data, 1953).
Periplaneta americana, U.S.A. (Roth and Willis, unpublished data, 1953).
Supella supellectilium, U.S.A. (Roth and Willis, unpublished data, 1953): See plate 31.
Our specimen caught a small American cockroach nymph that we placed in its jar. Before it had finished its meal, it caught and held two other nymphs with its legs while it continued to feed on the first. The body of this centipede reaches a maximum length of 27 mm. and it is usually found in basements, dark corners, or in spaces in the walls (Auerbach, 1951). Introduced from Europe, this species is now widespread in the United States (Crabill, 1952).
Allothereua maculata (Newport)
Synonymy.—Scutigera maculata [Crabill, personal communication, 1957].
Natural prey.—Cockroaches, Malay peninsula, Batu caves (Ridley in Annandale et al., 1913): This is a presumptive host record.
