external cotton-like subiculum. The spores and sporophores are 

 also larger and more robust than similar bodies of the other 

 species. 



It should be mentioned that the characters of the spores and 

 sporophores bear a certain resemblance to the analgous struc- 

 tures of Acremonium danysz Wize (1904), a parasite of Cleonus 

 punctiventris in Russia. 



4. Hirsutella citriformis sp. nov. 



Entomogenous. Synnemata usually long, flexible, arising 

 sometimes from a subiculum, sometimes directly from the body 

 of the host, brown in color, simple or branched. Branches often 

 short and stumpy, and easily detached. Sporophores simple, 

 sessile or subsessile, with rather short, delicate sterigmata (20- 

 30 microns). Spores fusoid, hyaline, 5.5-8.5X1-5-1.8 microns 

 in size, imbedded in gelatinous matrices. 



Hosts: Fulgoridae (adult), New Zealand. 

 Fulgoridae (adult), Porto Rico. 

 Ricania discalis, New Zealand. 

 Perkinsiella saccharicida, Hawaii. 

 Siphanta acuta, Hawaii. 



5. Hirsutella fusiformis sp. nov. 



Entomogenous. Synnemata erect, straight, unbranched, uni- 

 form in height, measuring 4-5 mm., nearly black in color, arising 

 from the leg joints and sutures of the host's body, singly. Sporo- 

 phores simple, sessile, the inflated basal portion tapering 

 gradually to rather short (25-35 microns) sterigmata. Spores 

 fusoid-cylindrical, measuring 9-10 X 2 microns in size, hyaline, 

 imbedded in gelatinous matrices. 



Host: Cricket (adult), Hawaii. 



It is quite impossible from the data at hand to determine 

 whether or not Isaria surinamensis Voss. is identical with any of 

 the above species. In the writer's opinion, however, it un- 

 doubtedly is closely related to them and should therefore be 

 placed in the genus Hirsutella, and if distinct it should be called 

 H. surinamensis (Voss). In a similar manner it is difficult to 

 ascertain the true nature of Isaria sphaecophila Ditm., and though
