Synonyms and other taxonomic changes
Group B - an artificial group of Pachybrachis spp. called out by Fall (1915), the last person to revise Pachybrachis. (1)
Identification
This group includes those species which are--so far as Fall (1915) knew--normally almost entirely yellow or testaceous at least so far as the elytra are concerned. (1)
Remarks
Spp. recognized by Fall (1915) as members of Group B
(Starred species (*) are tabulated in more than one group though most of their elytral markings are usually quite small and inconspicuous)
