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 (Hub- 

 bell, 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 



This is a cosmopolitan domiciliary pest (Hebard, 1917; Rehn, 

 1945). It is common in restaurants, grocery stores, bakeries, and 

 where food is prepared or stored ; it was trapped regularly in the 

 basement and upper floors of store buildings, and it was also found 

 in all heated parts of an old meat-packing plant (Gould and Deay, 

 1938). P. americana was numerous in latrines in Iran (Bei-Bienko, 

 1950) and in privies in Texas (Dow, 1955) and Georgia (Haines 

 and Palmer, 1955). Large numbers of this species also occur in 

 sewers adjacent to human habitations (Roth and Willis, 1957a). 



Periplaneta australasiae 



Generally domiciliary, but also occurs outdoors in the West Indies 

 (Rehn and Hebard, 1927). It is a very abundant domiciliary pest in 

 tropical Africa and tropical America (Rehn, 1945) ; Ecuador (Cam- 

 pos R., 1926) ; Puerto Rico (Sein, 1923) ; Philippine Islands 

 (Uichanco, 1953) ; Australia (Pope, 1953). 



Also occurs as a pest in greenhouses in Pennsylvania (Thilow and 

 Riley, 1891) ; France (Giard, 1900) ; Italy (Boettger, 1930) ; Great 

 Britain (Laing, 1946; British Museum [Nat. Hist.], 1951). 



Periplaneta brunnea 



Circumtropical domiciliary pest which is apparently more nearly 

 peculiar to the Tropics and adjacent regions than P. americana 

 (Hebard, 1917). This species has been trapped in significant numbers 

 in privies and dwellings in Georgia (Haines and Palmer, 1955). It is 

 the species of Periplaneta present in homes in San Antonio, Texas 

 (MaUis, 1954).
