Parcoblatta sp., U.S.A., Ohio (Edmunds, 1953a).
Periplaneta americana, Africa (Crawford, 1910; Nash, 1955): Nash's record was incorrectly attributed to Syntomosphyrum glossinae Wtstn., a parasite of tse-tse fly pupae (Jordan, 1956), Formosa (Takahashi, 1924; Sonan, 1924); Palestine (Bodenheimer, 1930); Puerto Rico (Seín, 1923; Plank, 1947, 1950; Wolcott, 1951); St. Croix, Virgin Islands (Beatty, 1944); Hawaii (Schmidt, 1937); U.S.A.: Missouri (Rau, 1940a); Ohio (Edmunds, 1955); Florida (parasitized oöthecae were collected near Orlando by members of the Orlando Laboratory, Entomology Research Branch, U.S. Department of Agriculture; the parasites were identified by Burks, personal communication, 1955). Fiji (Lever, 1943); India (Mani, 1936; Usman, 1949); Trinidad and Saudi Arabia (Cameron, 1955). Westwood (1839) stated that 70 parasites belonging to the genus Eulophus emerged from an oötheca of P. americana collected on shipboard. Burks (personal communication, 1955) stated that the wasp was probably T. hagenowii.
Periplaneta australasiae, Australia (Shaw, 1925); India (Usman, 1949); Saudi Arabia, Trinidad (Cameron, 1955); Formosa (Sonan, 1924).
Periplaneta brunnea, U.S.A., Florida (parasitized oöthecae were collected near Orlando, by members of the Orlando Laboratory, Entomology Research Branch, U.S. Department of Agriculture. The parasites were identified by Burks, p. c., 1955).
Cockroach eggs, Formosa (Maki, 1937); Ceylon (Waterston, 1914): Taken on an oötheca.
"Domestic cockroaches," U.S.A., Louisiana (Girault, 1917).
"Roach egg cases," Panama Canal Zone (Rau, 1933).
Evania sp., Hawaii (Ashmead, 1901; Perkins, 1913); Guam (Fullaway, 1912); Fiji (Lever, 1946); Europe, Cuba, Florida (Marlatt, 1902, 1915).
Experimental hosts.—Blatta orientalis, Eurycotis floridana, and Periplaneta americana, U.S.A. (Roth and Willis, 1954b): We have maintained T. hagenowii for over two years through more than 30 generations on eggs of both B. orientalis and P. americana.
