Ohs. This is certainly Mr. Kirby’s Leptura ceramboides^ and 
perfectly agrees with the Fabrician description of the Ceramhyx 
abbreviatus, except that no mention is there made of its mouth being 
yellow. Mr. Kirby says of this insect, “ a habitu Lepturce omnino 
recedit Cerambycibus propior," and certainly were it allowable to 
judge entirely from habit, it would seem to connect those American 
Saperdce of Fabricius and Olivier which have bearded antennae, 
such as (S, plumigera, Oliv., barbicornis^ Fab.) with some other 
family, perhaps the (Edemeridce. But, however this may be, the 
genus Stenoderus differs from the CerambycidcBy and agrees with 
the Lepturidmt inasmuch as it has the antennse inserted between 
the eyes.
