_Sarawak, Borneo._--Swarming on walls of caves and in soft bird guano on the cave floor (Moulton, 1912). Hanitsch (1931) noted that this species was first recorded by Shelford from a cave in Sarawak and that there is a series from a cave in the Oxford University Museum, taken by Banks in 1928. _Malaya._--On the walls of the inner cavern of a cave at Biserat; the insects covered the walls in places (Chopard, 1919). _Sumatra._--From Baso cavern, on the west coast (Hebard, 1929). =Symploce curta= _South Celebes._--Hanitsch (1932). =Symploce remyi= _Tonkin._--This seems to be a true cavernicolous species (Chopard, 1929a; Colani, 1952). =Tivia macracantha= _Belgian Congo._--A troglophile without well-marked adaptive characters (Chopard, 1950a). At Haut-Katanga, troglophile and guanophile (Leleup, 1956). =Tivia= sp. _Madagascar._--Last-stage nymphs captured in guano in Antsinomy grotto (Chopard, 1949a). =Typhloblatta caeca= _India, Assam._--An eyeless species with noticeably elongated appendages (Chopard, 1945). =Typhloblattodes madecassus= _Madagascar._--Unpigmented integument and reduced eyes (Chopard, 1945). =Xestoblatta immaculata= _Panama._--Found under rocks on guano-covered floor of the Chilibrillo bat caves (Caudell, 1924). =Unidentified cockroaches= _Malaya._--The walls of a cave were covered by dense groups of a species of "_Blatta_" (Annandale, 1900). _England._--"The chief insect pests of the mines are cockroaches, which often swarm in hot mines and those with pit pony stables...."

(Hebard, 1917). =Arenivaga bolliana= _Texas._--In the nests of wood rats, _Neotoma_ sp. (Hebard, 1917; 1943a). =Arenivaga erratica= _Arizona._--The wingless females were commonly found in burrows of _Dipodomys spectabilis spectabilis_ Merriam, the kangaroo rat. The winged males were never found in the burrows (Vorhies and Taylor, 1922). Found most commonly in wood-rat and ground-squirrel dens in the desert regions (Ball et al., 1942). =Arenivaga floridensis= _Florida._--Found in a burrow of _Peromyscus polionotus rhoadsi_ (Bangs), the white-footed mouse (Young, 1949). =Arenivaga roseni= _Turkmen S.S.R._--Occasionally found in burrows of _Rhombomys opimus_ Lichtenstein; in the burrows of the desert turtle, _Testudo horsfieldi_ Gray; and frequently in burrows of the ground squirrel, _Spermophilopsis leptodactylus_ Lichtenstein (Vlasov, 1933; Vlasov and Miram, 1937). =Arenivaga tonkawa= _Texas._--An immature specimen was found in a prairie-dog hole (Hebard, 1943a). =Cariblatta lutea= _Florida._--It has been taken in burrows of the pocket gopher, _Geomys_ sp. (Hubbell and Goff, 1940). =Euthlastoblatta abortiva= _Texas._--In the nests of wood rats, _Neotoma_ sp. (Hebard, 1917). =Parcoblatta fulvescens= _Texas._--In the nests of wood rats, _Neotoma_ sp. (Hebard, 1917).
