 beneath but not contorted nor with irregularities, two-thirds as long 

 as the tarsus, the metatarsus two-thirds to four-fifths as long as the 

 remaining segments united, the fourth as long as wide ; hind tibia three- 

 quarters as long as the tarsus; the metatarsus straight, without an 

 apical lobe, as long as the following segments united ; the fourth seg- 

 ment longer than wide.
