I have, therefore, figured the remains found, which are all from the collection of Mr llartt, and which have been kindly described by Mr Scudder of Boston, one of our best authorities on questions of this kind. They were all Neuropterous insects, and allied to the Ephemeras. It is interesting, however, to observe that, like many other ancient animals, they show a remarkable union of characters now found in distinct orders of insects, or constitute synthetic types, as they have been named. Nothing of this kind is more curious than the apparent existence of a stridulating or musical like that of the cricket, in an insect otherwise allied to the Ncuroptera. This structure also, if rightly interpreted by Mr Scudder, introduces us to the sounds of the Devonian woods, bringing before our imagination the trill and hum of insect life that enlivened the solitudes of these strange old forests. Mr Scudder has kindly furnished descriptions of these insects as follows:â Fig. 181.âPlatepliemera nnti'qiia, Scntlder. ^z:/. *'The direction of the principal ncrvurcs in this insect convinces me that it belongs to the Ephemerina, though I have never seen in living Ephemerina so much reticulation in the anal area as exists hereâso, too, the mode in which the intercalary nervules arise is somewhat peculiar. It is a
