These figures represent feet or their appendages, in whole or in part, from different beetles ; similar 
letters are affixed to the parts as on the preceding plate.

of these still more enlarged ; a nr , extremity of one, flattened by pressure against the glass ;

Fig. 22. Amara communis, 6 : e", one of the appendages (tenent hairs), in profile: additional letters as 
with fig. 20. 
Fig. 2.3. Carabus granulatus, 8 : tenent hairs projecting from the third basal tarsal joint, at its anterior edge. 
Fig. 24. Ocypus olens: e, section lengthwise; i, portion of tarsus of another specimen, showing injury 
to the tenent hairs. 
Fig. 25. Small Staphyline beetle: hand. 
Fig. 26. Another small Staphyline {Tachyporus hypnorum). This has proportionately large tenent 
hairs on the hands; on the middle and hind legs these appendages are much smaller; a few 
bifurcate hairs are present with the latter, at the distal extremity of the third tarsal joint
