A Brief Review of our Species of MAGDALIS, with 

 Notes and Descriptions of other North 

 American Rhynchophora. 



BY H. C. FALL. 

 MAGDALIS Germ. 



The following notes are the result of an attempt to sepa- 

 rate in my own collection the species of this genus having 

 simple claws. A small number of specimens have been con- 

 tributed or loaned for study by Dr. Van Dyke, Mr. Frederick 

 Blanchard, Mr. C. A. Frost and Mr. Percy G. Bolster, but 

 the conclusions reached have been based for the most part 

 solely on my own material. Some of these conclusions I 

 have held to be in a measure tentative, but in this connection 

 it is gratifying to add that an examination of upward of 500 

 specimens from the National Museum and Forestry Collec- 

 tions, which unexpectedly came to me shortly after the com- 

 pletion of this manuscript, has left the systematic conclusions 

 virtually unchanged. This large collection has furnished, 

 however, a considerable number of localities and some inter- 

 esting biological data. 



The group of forms in the vicinity of gentilis is particu- 

 larly puzzling and troublesome, owing perhaps to the greater 

 or less instability of many characters generally useful in 

 determining species. Certain individuals tend to bridge the 

 gap between this species {gentilis) and some of the assumed 

 varieties of lecontci, and a more thorough study of long series 

 from many localities, coupled with a knowledge of life his- 

 tories is needed here. 



In the following descriptions length of body is measured 

 from the base of the beak to the tip of the elytra ; the point 

 of antennal insertion is taken as the anterior basal extremity 

 of the scape at the point of junction with the ball and socket 

 joint. 



The types of all the new species described in this paper 

 are in my collection. 



Our species may be primarily grouped as follows :
