138 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I4I 



Experimental Jiosts. — Neostylopyga rhomhifoUa (Richards and 

 Smith, 1954) : A few plants matured. 



Pycnoscelns surinamciisis (Richards and Smith, 1954) : Some de- 

 velopment but no mature plants. 



The fungus (fig. i) is found on antennae (pi. 27, B, C), palpi, 

 cerci, and femurs. Thaxter (1931) believed H. stylo pygae to be 

 synonymous with H. periplanctae. However, Richards and Smith 

 (1954) concluded that H. stylopygae would not grow on P. americana 

 under their laboratory conditions although H. periplanetac would grow 

 on B. orientalis. This indicated a strain or species difference between 

 the two fungi. Gunn and Cosway (1938) reported a species of Stig- 

 matomyces on the antennae of B. orientalis; this fungus was probably 

 H. stylopygae (Richards and Smith, 1956). 



Herpomyces supellae (Thaxter) 



Natural host. — Supclla supellectiliiim, Trinidad (Thaxter, 1931J: 

 On antennal spines. 



Herpomyces tricuspidatus Thaxter 



Natural hosts. — Blahcrus craniifer, U.S.A., Key West (Richards 

 and Smith, 1955). 



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, Min- 

 danao (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. tri- 

 cuspidatus. 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. ectohiae, II. 

 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.
