_Madagascar._--Thought to have been introduced into the cave entrance by man (Chopard, 1945, 1949a). IN MINES _Great Britain._--In a coal mine at Pontewydd where they had been established for some years (Lucas, 1916). In the Pentre Pit mine where they were abundant (Lucas, 1918). Abundant in a Welch mine 2,166 feet below the surface (Lucas, 1925). This species was found quite commonly in a number of South Wales coal mines; in one deep mine a white-eyed mutant form comprised about 5 percent of the cockroach population for the preceding 11 years (Jefferson, 1958). _India, western Bengal._--Very numerous in coal mines where the sole food apparently was human faeces (Chandler, 1926). _South Africa._--Numerous in four deep-level gold mines on the Witwatersrand. _Sumatra._--Numerous males and females from Sawah Lunto "'from a coal mine where they lived in great numbers on the faeces of miners'" (Hanitsch, 1929). =Periplaneta australasiae= _Sarawak._--Found swarming on walls of caves and in soft bird guano in company with _Symploce cavernicola_ (Moulton, 1912). _Tonkin._--Chopard (1929a); Colani (1952). =Periplaneta cavernicola= _Malaya._--Taken on walls of inner caverns, where they were particularly abundant (Chopard, 1919). =Periplaneta lata= _Tonkin._--Chopard suggested that its presence in caves is probably linked with man (Chopard, 1929a; Colani, 1952). =Periplaneta= sp. _Malaya._--From a cave in Jalor (Annandale et al., 1913). =Perisphaerus= sp. _Malaya._--The wingless females and nymphs mined in bats' guano in a cavern of the Jalor caves (Annandale, 1900). =Polyphaga aegyptiaca= _Turkmen S.S.R._--Females found in front part of Bakharden bat cave on several occasions (Vlasov, 1929). _Turkey._--At Magharadjik and Arab Dede, found in caves with various other animals (Lindberg, 1954). =Polyphaga= sp. _Burma._--Hsin Dawng Cave, S. Shan States, 1 immature male under stone in complete darkness (Chopard, 1924b). =Pycnoscelus niger= _Tonkin._--Apparently not an accidental inhabitant as nymphs were present (Chopard, 1929a; Colani, 1952). =Pycnoscelus striatus= _Malaya._--Found burrowing in bats' guano at entrance to caves in Selangor, where it was very abundant 50 to 600 feet from entrance; also on walls of inner cavern (Chopard, 1919, 1929). In the absence of other evidence, the presence of _P. striatus_ in a cave indicates that bats also inhabit the cave (Chopard, 1929a). =Pycnoscelus surinamensis= _Assam._--Found 300 to 400 feet from entrance of Siju cave in the Garo Hills (Chopard, 1924b). _South Celebes._--Hanitsch (1932). =Spelaeoblatta gestroi= _Burma._--Chopard stated that this species shows marked characteristics of adaptation to a life in darkness (Bolívar, 1897; Annandale, 1913; Chopard, 1919). =Symploce breviramis= _South Celebes._--Hanitsch (1932). =Symploce cavernicola=
