Beetles of Special Concern

The following species have all been proposed for federal listing as threatened or endangered at one time or another. All were dropped from consideration due to insufficient data to make any listing decision. So they have no formal legal status at present. However, the California State Department of Fish and Game does track records of these 'species of special concern', and would welcome data on their occurrence.
