FUNGOUS INSECTS AND THEIR HOSTS. 

 BY HARRY B. WEISS AND ERDMAN WEST. 



This paper is an attempt to list in a definite manner, the 

 various fungous hosts of certain insects. In most entomo- 

 logical papers dealing with fungous insects, the host is recorded 

 simply as a "fungus." This is very indefinite and almost as 

 unsatisfactory as using the term "evergreen" when a definite 

 tree such as Pinus sylvestris is meant. In 1908 1 Schwarz called 

 attention to the opportunity of working with fungous insects in 

 view of the many mycologists in the field. At the present 

 time with more mycologists in the field certainly some attempt 

 should be made to list the fungous hosts by at least their 

 generic if not specific names. 



The present paper deals almost entirely with the Coleoptera 

 although some insects in other orders are included and the 

 records are the results of observations made for the most 

 part in New Jersey during the past year. No attempt was 

 made to breed out the various fungous gnats whose larvae 

 are so common in gill fungi. The few records copied from pub- 

 lished data are followed by the references. The records from 

 States other than New Jersey are due to the kind cooperation 

 of the entomologists whose names appear after such records. 



We are greatly indebted to Mr. Chas. Leng for identifica- 

 tions in the Coleoptera and for references to the literature. 

 It is hoped that in a later paper it will be possible to include 

 a bibliography of all publications in which the generic or spe- 

 cific name of the fungus is given, although such references are
