In addition to the forms above enumerated, which include one hundred and fifty -two species 
and twentj-eight jrencra, a certain number of undescrihcd forms arc known, inchiding several 
new genera. Of these, three species belong to f lie genus Laboulbonia, two of them Xortli Ameri- 
can, on Bledius and Anop]ithaImus,and one European, on Patrobus (IVyritsch) ; one to Cantharo- 
myces, on Ancyrophorus ; one to Chitonomyces, on an unknown host, together with a new jrcnus 
on Bledius, and a doubtful genus on Tachinus. The total number of forms known to exist' 
excluding certain doubtful species referred to by Peyritsch, is thus one huudrcd and fifty-ei^ht.^ 
Although this number may be assumed to illustrate the grouj> in a general way, it is certain ' 
that many important additions are inevitable, and from flie data available a rough estimate of 
Sistent 
thousand. 
The following descriptions, a majority of which first appeared in the "Proceedings" of the 
Academy, have been largely rewritten and revised with additional notes in (he light of more 
abundant material and a more complete knowledge of the group. As will be observed, a limited 
number are here described for the first time, and include some of the most im|.or(ant additions 
to the family.
