RENIA. 
Renia, Lewis, Ann. & Mag. Nat. Hist. 5th ser. xv. p. 467 (1885). 
Only two species of this genus have been as yet brought to light; one is from Parana, 
and the other from Mexico. The last named was found in ants’ nests, under stones.

This species is much smaller than &. meticulosa, Lewis, and differs in sculpture and

and has its anterior angles less produced, the sutural stria (which is tuberculous in 
R. meticulosa) is wholly wanting, and the four hinder tibize are angulate in the middle 
on the outer edge. ‘Two specimens.
