_Blaberus_ sp. and _Epilampra?_ sp., Panama (Thaxter, 1902, 1908). _Epilampra_ sp., Saint Kitts, B.W.I., and Haiti (Thaxter, 1902, 1908). _Leucophaea maderae_, Fernando Po (Spegazzini, 1915). _Nauphoeta cinerea_, Brazil (Thaxter, 1931). Cockroaches, China? (Thaxter, 1902); Philippine Islands, Mindanao (Thaxter, 1931). _Experimental hosts._--_Blaberus craniifer_, U.S.A. (Richards and Smith, 1955). Infections on the antennae. Richards and Smith (1954) were unable to secure experimental infections in _L. maderae_ with _H. tricuspidatus_. Experiments with _N. cinerea_ showed some development but no mature plants although identification of the growing fungus was uncertain because of simultaneous exposure to _H. ectobiae_, _H. stylopygae_, and _H. tricuspidatus_. =Herpomyces zanzibarinus= Thaxter _Natural hosts._--_Eurycotis manni_, Brazil (Thaxter, 1931): On antennae. _Gyna_ sp.?, Isle of Nias (Spegazzini, 1915): On antennae. Cockroach, Zanzibar (Thaxter, 1902): On antennae. =INCERTAE SEDIS= According to Dr. R. K. Benjamin (personal communication, 1957) and Dr. E. G. Simmons (personal communication, 1957), the phylogenetic position of the following genus is uncertain. =Amphoromorpha blattina= Thaxter _Natural hosts._--Cockroaches, Grenada, B.W.I. (Thaxter, 1920): On the axis of the antennae of a dark wingless and a pale winged blattid. =Amphoromorpha= sp. _Natural host._--Cockroach, Grenada, B.W.I. (Thaxter, 1920): On antennal setae. IX. HIGHER PLANTS The significance of many observed associations between cockroaches and the higher plants is still obscure. Undoubtedly many associations are ecological, but lack of adequate supporting evidence makes this conclusion somewhat tentative. The ecological aspects are covered in Section III (p. 14). Other associations may be accidental (e.g., certain unique observations that have never again been confirmed). In the absence of contrary evidence, most associations are presumed to be benign; exceptions to this conclusion are found among the cockroaches that feed on living plants (p. 162) and those allegedly captured as prey by the carnivorous pitcher plants (_Sarracenia_ and _Nepenthes_). In all the records cited below the cockroaches were stated to have been on, in, or feeding on the plant. The plants are listed below by family according to the taxonomic arrangement of Lawrence (1951). Botanical nomenclature follows Bailey (1925), Fernald (1950), or Dr. R. A. Howard (personal communications, 1958, 1959). We take full responsibility for referring to appropriate taxa certain plants that were reported by common name only in the cited literature. Division PTERIDOPHYTA Family CYATHEACEAE =Alsophila= sp. _Associate._--_Pycnoscelus surinamensis_, Louisiana (Anonymous, 1893): Feeding on heart of tree fern. Family POLYPODIACEAE =Asplenium nidus= Linnaeus _Associate._--_Comptolampra liturata_, Malaya (Karny, 1924): Often found between dry foliage of the beakers of this fern.
