tore wings broader and more ample, its groinid colour whiter, 

 and the white band outside the dark central band is broader, 

 much whiter, and only in the faintest degree intersected by 

 minute grey cloudy dots. In M. suhtridaia, with rather 

 laore narrow fore wings, this white stripe, also narrower, is 

 regularly divided lengthwise throughout by a delicate grey 

 dotted line. There is also a difference between them in the 

 form of the large outer angle of the second line, which is 

 sharper in the present species than in M. ■rini/d. The larv« 

 are also very similar, but the Eev. J. Hellins says that in 

 -)/. rivafa the colour is more delicately tinted, and the lines 

 more distinctly defined, while in jlJ. fuibfri^/iifn the dorsal 

 surface is clouded and the lines obscured, and the arrow-head, 

 or horse-shoe, markings between segments four and five, and 

 between nine and ten, are more distinctly formed. Mr. Prout 

 says that the stas'e at which the greatest distinction exists 

 is after the first change of skin, when the larva of 31. rir/ita 

 is bright green, almost apple-green, and its surface smooth ; 

 while at that stage the larva of M. suhtristata is of a more 

 dull, glaucous green, and that it is a little rugose laterally.
