A REVISION OF THE APION SUBGENUS TRICHAPION 

 WAGNER IN THE NEW WORLD (COLEOPTERA : CURCU- 

 LIONIDAE) 



By David G. Kissinger 



This paper ^ is one of a series in which the species of Apion occurring 

 in the New World will be revised. Acknowledgments, explanation of 

 measurements, and explanation of abbreviations used to designate 

 deposition of specimens are given in the first paper in the series 

 (Kissinger, 1957a). 



Ninety-two species are treated; of these 17 are new, 11 were not 

 seen by the autlior, and four are known to the author only from the 

 female. Of the 1 1 species not seen, eight were originally included in 

 the subgenus by Wagner, the other three species, laminatum Sharp, 

 peninsulare Fall, and tabogense Sharp, were adequately described or 

 figured so that it has been possible to place them in this subgenus. 



A key to the males of the Nev/ World species of subgenus Trichapion 

 is presented. The species either unknown to the author or repre- 

 sented by females only are not included in the key. The species 

 treated are arranged in groups as shown in table 1. The structural 

 characters of these groups are summarized in tables 2 and 3 and are 

 discussed after the definition of the subgenus. 



« Based on a thesis submitted In ]957 to the Graduate School of the University of Maryland hi partial 

 fulfillment of the requirements for the degree of Doctor of Philosophy. The research was aided by a grant 

 from the Sigma Xi-RESA Research Fund.
