MALTHODES, Kiesenwetter. 
This genus contains about a hundred and twenty species, of which 
about a hundred are found in Europe; a few have been described from 
North America and Ceylon ; in general appearance they closely resemble 
Malthinus, but are distinguished by having the mandibles without a 
tooth, the antennz inserted near eyes, and the head and thorax almost 
smooth or finely punctured; eleven species occur in Britain; they are 
hard to arrange in a table, as the externally evident differences are in 
many cases slight and misleading, and the chief distinctions are found 
in the sexual characters; the table given below must therefore be 
regarded as merely provisional, and must only be taken in conjunction 
with the detailed descriptions ; the species vary very much in size.
