Now while believing in the unity of the Xeu-ropterous type, and that the so called false Neuroptera (especially the May-fliesand the dragon-flies) are really the most typical of the suborder, being the mostunlike other insects, do not we have many characters in these palaeozoic net-veined insects, which unite more intimately the so called false and true Neurop-ters ? We would not forget the analogies shown in these fossil net-veined insect*. 684 XEUROPTEEA. It is ti rather large insect, the head and mouth-parts measur-ing thirty-nine millimetres, the three thoracic rings twenty-eight millimetres, and the part preserved of the right upperwing forty-four millimetres, and of the right under wing fifty-one millimetres. The antenme are long and thread-like, as inPanorpa, and the venation of the wings are of the Nenropter-ous type, while the elongated mouth-parts are Ilemipterous inappearance, though the labial palpi (A e) are well developed,being usually absent in the Ilemiptera. It is the most puz-zling form j-et brought to light, and has been compared byDr. Dohrn to the fossil Archaeopteryx of the Solenhofen slates,referred by some naturalists to the birds, and by others to thereptiles.
