446 COLEOPTERA OF NORTH AMERICA, 



have been removed and will constitute portions of tribes in Divi- 

 sion II. with wide metasternal side pieces. 



Our genera form four groups which may be distinguished as 

 follows : — 



Funicle 6-joiiited ; articular surface of hind tibiae inclosed, tips of hind 

 tibiae truncate with broad oval space. Ageaphi. 



Funicle 7-.iointed ; articular surface free, tips of hind tibiie witli a single 

 row of fimbria ; 

 CJaws free ; 



Antennae long ; outer joints of funicle long. Otioriiynchi. 



Antennae shorter ; outer joints short or moniliform. Tracuyphlcei. 

 Claws connate ; 



Antennae as in Otiorhjnchi. Periteli, 



The Periteli should follow the Otioriiynchi from their greater 

 similarity of form and structure, the only difterence between the 

 two groups is found in the form of the claws. 



Group I. — Agraphi. 



Antennffi moderate, scape longer than the funicle and club, 

 moderately arcuate; funicle 6-jointed; club broadly oval slightly 

 flattened, composed in great part of the first joint only, the other 

 joints retracted and very indistinct. Tarsi long, slender, third 

 joint very feebly emarginate and scarcely wider than the second. 

 Hind tibiiB truncate at tip with brond, oval smooth space, cotyloid 

 cavities internal. Anterior tibite with outer apical angle slightly 

 prolonged; anterior and middle tibiae with inner angle niucronate. 



The above characters appear to warrant the' separation of 

 Agraphus as a group by itself, as suggested by Lacordaire, who, 

 however, failed to notice the structure of the antennal club and 

 placed the genus in a group in which the cotyloid cavities of hind 

 tibiie are open. These latter are really very strongly cavernous, 

 more so in fact than in any other genus in our fauna. 



Acjraphus bellicus alone constitutes this group, and is found 

 in the Atlantic States. 



Group II. — Otiorhynchi. 



Antennas long, rather slender, scape passing slightly the ante- 

 rior margin of the thorax, funicle 7-jointed, first two joints longer 

 than the others, joints 3-7 obconical, moderately long, club oval, 

 acute at tip. Cotyloid cavities of hind tibiiB terminal. Tarsal 

 claws free.
