 identity with the Xhwv ^^vwvrx eniunerated in the synonymy iri generally recognized, 

 though De Toni and a few others j>re.serve the sej)arate rank of rieurodesniium and 

 Ilydnjsera. In regajd to the former it is sufTicient to note that the only striking differ- 

 ence is its liner beading of the middle l>and (zonal view) and coarser beading of the 

 lateral I)ands, and we find in T. intermedia (irun.^ an otherwise typical T. musira^ the 

 beading of Vleurodesmvnn hrcbissonii Kutz., so that, as Grunow says,a- the two genera 

 are certainly the sain{\ Tlie genuis Tetragramma was made on such insufficient dis- 

 tinctions tliat Bailey himself afterwards abandoned it. b Ilydrosera even in its usual 

 triangular form shows tlu.^ nmsic notes and all the characteristics of Terpsinoe.
