The insects found in these beds are of the very greatest geological interest, as being the oldest known representatives of that type. They occur in the same shales with tlie phints, and arc thus proved, both by stratigraphical and palivontological evidence, to be older than the Carboniferous perio( . 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:/.
