the base of the hfth segment, and apparently opening exter- 
nally. Further work has shown to me that this is always 
seated on the ganglionic enlargement of the nerve that 
supplies the appendage ; that it opens at the ring marking 
the insertion of the appendage ; that in the male it contains 
one or several irregular brightly refractive bodies, floating 
freely in its cavity. Hence I regard this organ as an ear, 
less developed in the female than the male. 
At p. 180, vol. 15, of the Proceedings of the Literary and 
Philosophical Society Mr. Plant described a “Beetle of 
good omen from Yucatan,” at which time he was unable to 
give the generic and specific name. This can now be sup- 
plied, as a similar specimen has been shown at a meeting of 
the Entomological Society of London, by Mr. Randolph 
Clay, from Mexico, and recognised as Zopherus Bremei.
