[1505] Latreille speaks of Phasma as having no stemmata; but it should seem that he examined only the apterous ones, all the winged individuals, at least so far as I have examined them, having three very visible ones. It may, I think, be laid down as a rule, that the larvæ and pupæ of Orthoptera have not these organs. Probably their use is principally in flying?
[1506] Flata phalænoides F. and affinities have no stemmata, while Flata reticulata and affinities have them: a proof that these tribes are distinct genera.

[1508] Reaum. iv. 243. He refers for this insect to plate xiv. without adding any number for the figure; but no such is in that plate.
