' Melissodes Is asually credited to Latreille, but it was defined, and species assigned to it, by 

 F. Smith in 18.54. Lepelatier described wliat was understood to be Latrellle's insect as Melissoda 

 latreillii; this is Acanthopus goryi Remand. Mr. J. C. Crawford writes in a letter that Romand in 1841 

 included a spcci&s iu Melissodes: I have not had access to this worlc.
