Agra sp. (unknown group)

(one specimen from Erwin’s site, Figs. 16–18 )

Size: Head width, 1.0 mm; body length, 8.0 mm. Mandibles markedly exceed in length maxillary and labial palpi, retinaculum markedly developed ( Fig. 13 ), lateral seta present, nasale prolonged and broadly produced, head capsule perfectly quadrate and arrangement of setae different from other larvae ( Figs. 13–14 ), and trochanters and coxae armed with numerous tubercle­like spines ( Fig. 19 ).

Note: This specimen is either a large second instar or small third instar. Its attributes, somewhat different than the other three species above, are described and illustrated here to demonstrate the variability to be expected in this very large and diverse genus of carabid beetles.
