A REVISION OF NORTH AMERICAN CHRYSOBOTHRINI

clypeus is more or less variable in depth, and in the female the emar- 

 gination at the apex of the last visible abdominal sternite is slightly 

 variable in shape. In some of the specimens examined the lateral 

 callosities on the abdominal sternites are barely indicated. The lecto- 

 type has the anterior margin of the prosternum truncate, without 

 any indications of a median lobe, but in other specimens the anterior 

 margin is arcuately rounded, with a broad, very short, median lobe. 



The length is from 10 to 13 mm. 



Horn (1886) states in his table that there is "a well marked trans- 

 verse ridge in front of the notch" at the apex of the last visible 

 abdominal sternite of the female. Fall (1910) describes this as 

 follows : 



This apical ridge or carina consists of the free edge of the terminal portion 

 of the submarginal serrate ridge, leaving the apical portion, where it cuts 

 across the bottom of the emargination, smoothly outlined and a little deflexed, 

 and is best seen when looked at from behind and nearly in the axial line of 

 the body.
