A SYNOPTIC REVISION OF THE CUTEREBRID^, 

 WITH SYNONYMIC NOTES AND THE DE- 

 SCRIPTION OF ONE NEW SPECIES 



By CHARLES H. T. TOWNSEND 



The present paper deals only with those species represented 

 by adult material in the U. S. National Museum, totaling 108 

 specimens. A careful study of this material has disclosed many 

 errors which need correction. Certain species of the older 

 authors have been misidentified, certain valid species names 

 have been put in the synonymy, certain synonyms have been 

 used as valid names, and certain aberrant specimens of old 

 species have been described as new species. These errors are 

 corrected in the notes which follow the tables. The follov/ing 

 synopses will serve to separate the species treated.
