 Myodites is a Solidago visitor and parasitic on Epinomia. The 

 latter is only a visitor of Hcliaiithus. This fact indicates the 

 existence of an intermediate Host or carrier; hence there is a 

 necessity- for first ascertaining something concerning other Soli- 

 dago insects. 



SOLIDAGO INSECTS 



A list of bees frequenting the blossoms of Solidago, especially 

 rigida, has been carefully prepared for the author by Mr. J. C. 

 Crawford of West Point, Neb., and Mr. M. H. Swenk of the 

 State University. This list is large and by itself can give little 

 aid. Since Myodites appears with Solidago and disappears with 

 it, we may safely say that some one of these bees is probably 

 either a permanent or temporary host. 



The following is the list of the bees taken on Solidago rigida 

 at Lincoln and West Point, the two known homes of Myodites 

 solidaginis, by Mr. Crawford and Mr. Swenk.
