ADDITIONAL FUNGOUS INSECTS AND THEIR HOSTS. 

 BY HARRY B. WEISS AND ERDMAN WEST. 



Since the publication of our former list (Proc. Biol. Soc. 

 Wash. vol. 33, pp. 1-20, 1920), the following records have 

 accumulated. Our thanks are due to Mr. Chas. Dury for 

 identifications in the Cisidae, to Mr. H. Notman for his help 

 with the Staphylinidae and to Mr. C. W. Leng and Mr. C. A. 

 Frost for miscellaneous determinations in the Coleoptera. 

 Records not specifically credited were obtained by the writers. 

 Of special interest is the record by Mr. W. A. Hoffman of 

 Plesiocis cribrum from Polyporus volvatus at Albany, N. Y., this 

 species having been previously described and recorded from 

 California.
