Reported as a domiciliary pest in Madeira (Heer, 1864); Windward Islands (Marshall, 1878); Tropics and sub-Tropics (Rehn, 1937); Philippine Islands (Uichanco, 1953); New York City (Anonymous, 1953; Gurney, 1953); Trinidad (Princis and Kevan, 1955). This species is also established in coastal Brazil, Central America, all the Greater Antilles, several other tropical islands, and tropical Africa, where it probably originated (Rehn, 1945). =Leurolestes circumvagans= _Hispaniola, Grenada._--Largely domiciliary (Rehn and Hebard, 1927). =Leurolestes pallidus= _Cuba._--All over island, in houses, under lockers, etc. (Rehn, 1945; Gundlach, 1890-1891). _Florida._--Rehn and Hebard (1914). This species has been recorded from various islands in the West Indies, from Mexico, Guatemala, and Brazil (Rehn, 1945). =Methana marginalis= _Australia._--Reported entering houses (Pope, 1953a). =Nauphoeta cinerea= _Australia._--In hospital (Mackerras and Mackerras, 1948). In dwellings, grain stores, and fowl-feeding pens (Pope, 1953). _Sudan._--Domiciliary in huts of the Shilluk natives; fairly widely distributed in eastern Africa (Rehn, 1945). _Hawaii._--In feed rooms of poultry plants (Illingworth, 1942). _Florida._--Established in feed mills around Tampa (Gresham, 1952; Gurney, 1953). The wide distribution of this species from East Africa, where it originated, to the Orient and the New World was undoubtedly mediated by shipping (Rehn, 1945). =Neoblattella= sp. _Puerto Rico._--Observed [as _Blatta caraibea_, Rehn and Hebard (1927)] in houses (Gundlach, 1887). =Neostylopyga rhombifolia= Domiciliary in Indo-Malaya and New World Tropics (Rehn, 1945); Philippine Islands (Uichanco, 1953); and Hawaii (Hebard, 1922). =Oxyhaloa buprestoides= Presumably to some extent domiciliary, as it evidently spread from Africa to the New World via slave ships (Rehn and Hebard, 1927; Rehn, 1945). =Panchlora nivea= _Colombia._--A male and a female taken in a dwelling (Princis, 1946). This is primarily an outdoor species which is frequently taken indoors as an adventive on bananas (see p. 150 for references). =Parcoblatta fulvescens= _Florida._--Males found in laboratory and dormitory buildings, ostensibly attracted by lights (Friauf, 1953). =Parcoblatta lata= _Connecticut._--Domiciliary pest (Moore, 1957). Generally an outdoor species. =Parcoblatta notha= _Arizona._--It may occasionally be a nuisance in houses (Ball et al., 1942). =Parcoblatta pensylvanica= _U.S.A._--Country houses often badly infested, Indiana (Blatchley, 1920). Frequently taken in houses in wooded areas, Michigan (Hubbell, 1922). Infestation by males, females, and nymphs on fourth floor of building, South Dakota (Severin, 1952). Houses in wooded areas infested by nymphs and occasionally by adults (Gould and Deay, 1940). _Canada._--Pest in summer cottages in Ontario (Walker, 1912). =Periplaneta americana=
