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. Order SCOLOPENDROMORPHA Family SCOLOPENDRIDAE =Scolopendra cingulata= Latreille _Experimental prey._--Cockroaches, England (Cloudsley-Thompson, 1955): After capture in France, this specimen was kept for four weeks without food. She was then fed medium-sized nymphal cockroaches of which she ate an average of about one per week throughout the summer. Adult cockroaches were attacked only after they had been disabled. =Scolopendra morsitans= Linnaeus _Natural prey._--Cockroaches, Guadeloupe (Lherminier, 1837). _Experimental prey._--Cockroaches, India, Nagpur (Jangi, 1955): As soon as the centipede became aware of its prey, it rapidly embraced the cockroach within its legs and with its fangs gripped the insect's thorax. The predator continued to hold the prey with its fangs while its mouth parts prodded the victim's body. After feeding on an adult cockroach, the centipede is not inclined to kill another for 2-3 days. =Scolopendra subspinipes= Leach _Natural prey._--Cockroaches, Hawaii (Williams et al., 1931): This is a common species with a body length of 6 or more inches. It is reported to be a great enemy of cockroaches. =Scolopendra= sp. _Natural prey._--_Ectobius panzeri_, England (Lucas, 1911, 1920): When captured, the centipede was holding a live cockroach which it had apparently just caught. The insect was held beneath its captor's body, ventral surface upward, by several of the anterior legs while the centipede fed. Class INSECTA We have found representatives of only 10 orders that have preyed on or parasitized cockroaches: Beetles, flies, bugs, ants, wasps, stylops, and cockroaches occurred in nature; the others resulted from feeding cockroaches to captive insects or were laboratory observations. Order ODONATA Family AESHNIDAE =Anax strenuus= Hagen _Common name._--Giant Hawaiian dragonfly. _Experimental prey._--Cockroaches, Hawaii (Williams, 1936): The dragonfly nymph was fed with medium large cockroaches and other insects.
