MORE NOTES ON FUNGUS INSECTS AND THEIR HOSTS.^ 
By Harry B. Weiss. 
New Brunswick, N. J. 
Recently, Dr. George W. Martin sent me several species of 
beetles which he had collected on fungi in the neighborhood of 
Iowa City, Iowa, and they proved to be Bister lecontei Mars., on 
Mutinus elegans, August 11 (probably not feeding on the fungus); 
Mycetophagus punctatus Say feeding on Polyporus radicatiis, 
August 11; Mycotretus pulchra Say on Russula irrescens, July 4; 
Diaperis maculata Oliv., on Polyporus spraguei, July and Phe- 
nolia grossa Fab., on Polyporus sulphur eus, July 9. 
In the Pennsylvania Department of Forestry Bulletin No. 
12 (1915) Studhalter and Ruggles writing under the title, “In- 
sects as Carriers of the Chestnut Blight Fungus” review the 
more important publications dealing with insects which have 
been considered accountable for the spread of fungi or bacteria 
which are saprophytic or parasitic upon plants and from their 
own observations, found that nineteen out of fifty-two insects 
collected in the field were carrying spores of Endothia parasitica. 
They concluded that some insects carried a large number of 
spores of the chestnut blight especially the beetle Leptostylus 
macula. 
In the order Collembola, Folsom (Proc. U. S. Nat. Mus. voF 
50, p. 493) records Achorutes armatus Nic., as occuring commonly 
on agarics and on Boletus, Polyporus, Morchella, etc., and Xenylla 
welchi Folsom (Proc. U. S. Nat. Mus. vol. 50, p. 497) on mush- 
room beds in a greenhouse at Manhattan, Kansas. Alexander 
and McAtee (Proc. U. S. Nat. Mus. vol. 58, p. 413) state that 
Limnohia triocellata 0. S., (Diptera, Tipulidce) was reared from 
Clytocyhe sp., and Boletus felleus on Plummer’s Island. 
Upon looking into the European literature for records of 
fungus insects one finds as in American literature, a general
