DESCRIPTIONS OF SPECIES THE TYPES OF WHICH ARE LOST OK 
INACCESSIBLE. 
The types of the following" species have either been lost or are inacces- 
sible. The latter applies to the species described by William F. Kirby, 
the types of which are in the British Museum. It is probable that 
Eschscholtz's two species are not now obtainable. Of the other species, 
one each described by Say, Fitch, and Walsh, and the rest by Norton, 
the type specimens are lost and 1 have been either unable to recognize 
them from the rather inadequate descriptions or to secure additional 
specimens representing them. .V few of these species are so character- 
ized that it is possible with tolerable accuracy to refer them to genera, 
and in such cases 1 have indicated the probable genus to which they 
belong. Some of those referred to Pteronus may, however, belong to 
Atnauronemattts, and some of those referred to Pachynematus may 
belong elsewhere. The descriptions by Kirby are so inadequate that 
nothing can be determined of the position or relationship of his species, 
and to properly refer them will necessitate an examination of the types 
themselves. The species the genera of which can not be determined, 
are all given under the old term Nematus, though probably none of 
them belong in this genus as now restricted. The original descriptions 
are quoted without change, and, other than those of Kirby's species, 
are taken from Norton's Catalogue.
