_Puerto Rico._--In caladium, grass, weeds, coffee, and bananas; in flowers of _Ipomoea tiliasea_ (Rehn and Hebard, 1927). "... living in trees between leaves, or in 'butterfly-nests' of _Tetralopha scabridella_ in leaves of _Inga vera_, or of _Pilocrocis secernalis_ in the leaves of 'capá blanco' (_Petitia domingensis_) in the mountains. Along the coast they have been found under the bracts of cotton squares or bolls, and under the leaf-sheaths of sugar cane, in curled-up leaves of grapefruit, or in the dry flower clusters of 'espino rubial' (_Zanthoxylum caribaeum_)." These observations apply also to _Plectoptera infulata_ and _P. rhabdota_ (Wolcott, 1950). =Plectoptera floridana= _Florida._--On fringe of tall bushes at edge of mangrove swamp (Rehn and Hebard, 1914). Rehn and Hebard (1927) stated that on the Keys it frequented dry scrubby vegetation, particularly _Ilex cassine_. =Plectoptera infulata= _Puerto Rico._--See Wolcott's (1950) comments under _Plectoptera dorsalis_ above. =Plectoptera lacerna= _Cuba._--In grasses, sedges, etc., about a waterhole; on grass, pines and oak (Rehn and Hebard, 1927). =Plectoptera perscita= _Dominica._--On moss-covered lime trees (Rehn and Hebard, 1927). =Plectoptera porcellana= _Cuba._--Taken on flowers of "Júcaro" (Gundlach _in_ Rehn and Hebard, 1927). =Plectoptera pygmaea= _Jamaica._--In relatively dense forest foliage; in shrubbery (Rehn and Hebard, 1927). =Plectoptera rhabdota= _Puerto Rico._--In mixed vegetation; on grapefruit tree and guava (_Psidium guajava_); on bushes and shrubs (Rehn and Hebard, 1927). On coffee trees; on _Spondias_; on sugarcane; in caterpillar nests of _Tetralopha scabridella_ on _Inga vera_; in old cotton bolls; on grapefruit (Wolcott, 1936). See also Wolcott's (1950) comments under _Plectoptera dorsalis_. =Plectoptera vermiculata= _Cuba._--On pine in palmetto region (Rehn and Hebard, 1927). =Polyphaga aegyptiaca= _Algeria._--Nymphal females under decaying leaves at the end of November (Lucas, 1849). _Transcaucasia._--In burrows in argillaceous cliffs along ravines. Females often covered by attached clay particles, an indication, according to Bei-Bienko, that this species is ecologically connected to compact clay soils or at least does not avoid them (Bei-Bienko, 1950). See also the section on desert habitats (p. 29). =Polyphaga saussurei= _South-central Asia._--Occupies compact clay soils; distributed in drier regions than _P. aegyptiaca_; frequently found near dwellings, in yards, stables, and houses (Bei-Bienko, 1950). =Polyzosteria limbata= _Australia._--Common, usually "resting among the foliage or sunning itself on a fence or stumps, seldom or never hiding under bark or logs like most of the species" (Froggatt, 1906). =Poroblatta= spp. _Tropical America._--"The species of _Poroblatta_ apparently live as borers in stumps and logs in a manner similar to those of _Cryptocercus_ Scudder in the United States" (Gurney, 1937).
