a 
346 Mr. A. G. Butler on the 
Menpa, Walker. 
To this genus the so-called ‘‘ Molybdophora”’ concinnu- 
laria of Herrich-Schiffer must be referred, as also the 
** Nadagara” nigripalparia of Walker. What Guenée 
associated M. concinnaria and the concinnularia of 
Herrich-Schiiffer together for, | cannot at all comprehend ; 
certainly not for any similarity either of form or colora- 
tion; and as for the hyphinoé of Cramer, I can second his 
remark, ‘‘Je ne suppose pas qu’ Hyphinoé, Cram., 357 
G,H, puisse se placer ici,” inasmuch as that species, of 
which Dr. Trail took no less than eighteen specimens, is 
a Deltoid referable to Walker’s genus Gaala, and nearly 
allied to his Rethma. 
It is a singular fact that M. Guenée’s remark did not 
deter Mr. Walker from placing the Phalena hyphinoé of 
Cramer under Molybdophora, nor from regarding Rethma 
as a genus of Geometrites.
