PREFACE 



/ *TT S HIS volume is a continuance of the work contained in 

 the first volume, published in 1905. Like the first vol- 

 ume, it is simply a reproduction from scientific publications of 

 the descriptions of new species which have fallen into my 

 hands, with the addition of colored plates which are a neces- 

 sary adjunct to satisfactory descriptive work of this nature. 



The first volume comprised species from Bolivia and a 

 few from other districts. This volume is confined to spe- 

 cies taken in the neighborhood of the Suapure River in 

 Venezuela.
