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. I9, 
20) writes: ‘The larvae feed upon a fungus (Polyporus 
betulina) which is parasitic upon the trunks of white birch 
trees.’’ According to re (Fifth Rept. 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
