Although this genus had been placed by Latreille and other 

 writers with the Tetramera, I always considered that it was 

 allied to Hypophla;us (pi. 430.), and it was consequently placed 

 before that genus in the Guide; it was therefore very satisfac- 

 tory to find on examination that Khyzophagus is really an 

 Heteromerous group, as stated by Gyllenhal. The trophi, as 

 might be expected from their similar ceconomy, are consider- 

 ably like those of Hypophlaeus, with the exception of the ex- 

 ternal lobe, which is dissimilar to any I am acquainted with ; 

 and the antenna? resemble some of the Nitidulae.
