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).
