Notes on Thymalus fulgidus Er., and Its 

 Fungus Hosts in New Jersey (Col.). 



By HARRY B. WEISS, New Brunswick, New Jersey. 



This species, described by Erichson in 1844 (Germar. 

 Zeits., bd. 5, p. 458), has long been known to breed in Poly- 

 porus betulinus (Bull.) Fr., a fungus which occurs only on 

 species of birch and which attacks weakened trees with great 

 rapidity. G. Dimmock (Direct. Collect. Coleop. 1872, pp. 19, 

 20) writes: 'The larvae feed upon a fungus (Polyporus 

 hcfn/ina) which is parasitic upon the trunks of white birch 

 trees." According to Packard (Fifth Kept. U. S. Ent. Com., 

 1890, p. 510) the beetle is common in New England and a 

 large number of larvae taken in Belmont, Massachusetts, 

 produced, beetles after a short period of pupation, on or 

 about June 27, 1878. Smith (Ins. N. J. in State Mus. Rept., 

 1909) states that it occurs throughout the state of New Jersey
