_Virginia._--In decaying chestnut and pine logs; taken six times in chestnut and once in pine (Hebard, 1917). In rotten logs in deep ravines of moist woods (Davis, 1926). _Appalachian Mountains, U.S._--In southern Virginia and eastern Tennessee, it is usually quite abundant in well-forested areas at elevations from 3,000 to 5,000 feet; "sometimes even a majority of the dead logs on a mountain side have roaches in them" (Cleveland et al., 1934). This cockroach not only lives in rotten, dead logs but also in sound logs that have been down only a few years. In Virginia it is found more often in chestnut and hemlock. "It occurs fairly often in oak, and has been found in pine, spruce, and arbor vitae.... There is little evidence that they ever leave the log and enter the ground" (Cleveland et al., 1934). =Cryptocercus relictus= _Eastern Manchuria._--In great numbers under rotting fallen trees and in rotten dead wood (Bei-Bienko, 1950). =Cutilia soror= _Marquesas Islands._--Males under stones and dead log (Hebard, 1933a). _Hawaii._--In soil about roots of pineapple (Illingworth, 1927). Often found about roots of grasses and weeds and other debris (Williams et al., 1931). Under stones and pineapple mulching paper (Fullaway and Krauss, 1945). _Wake Island._--Numerous, some from rotten logs. Found in bunch grass on Ocean Island (Bryan, 1926). =Cutilia= spp. _Australia._--Frequent woods where they leave shelter soon after sunset and run actively on ground or ascend shrubs and trees in quest of prey (Tepper, 1893). =Dendroblatta sobrina= _Panama._--Colony on tree trunk; on surface of trunk of fallen tree (Hebard, 1920). =Diploptera punctata= _Hawaii._--"Crowds of these insects in various stages of development sometimes gather in cypress trees, in suitable chinks, in old flowerhead sheaths of palms, etc., and even more or less openly on leafy twigs, in bunch grass, and the species is at times locally abundant behind the older leaf bases of sugar cane" (Williams et al., 1931). Williams also lists the following as food plants: _Cryptomeria_, algaroba, lime trees, ripening mangoes, papayas, and oranges. However, Bianchi (personal communication, 1954) doubted that any of the above are the main dietary, because the largest populations he had seen "were found in the fairly dry litter of Star Jasmine (_Jasminum pubescens_ Willd.), well removed from any of the plants mentioned by Williams." _Raiatea, Society Islands._--Beaten out of bracken (Cheesman, 1927). _Uahuka, Marquesas Islands._--Under bark (Hebard, 1933a). =Dryadoblatta scotti= _Trinidad._--Very common in water-filled, epiphytic bromeliads in the rain forest (see p. 31) (Princis and Kevan, 1955). =Ectobius africanus= _Belgian Congo._--Females in forest margin and in forest undergrowth (Rehn, 1931). =Ectobius albicinctus= _South France._--Females and young beneath stones (Blair, 1922). =Ectobius duskei=
