(9) The writer (abbreviated P. P.C.). The Mexican material possessed by Mr. Adams 
and myself is, in large part, the result of recent collections by Mr. O. W. Barrett, 
of Clarendon, Vermont, to whose liberality and interest it is a pleasure to testify. 
It is also proper to include in this list (10) the collections from Mexico in the 
possession of the California Academy of Sciences at San Francisco, which, although 
already reported upon {, must be frequently quoted in the following pages. 
When no mention is made of the collection in which a given species is represented, 
that of Mr. Godman is to be understood.
