Scudder in theMemoirs of the Boston So-ciety of Natural History for1867, shows that the vena-tion of this genus recalls fea-tures of several other Neu-ropterous families, such as theTermitidce, the Hemero-biclce and Si alt dee. Mr. Scudder, who has given a restoration of this remark- --««^-==.—— able insect, states that the Ii- ••J head is somewhat like that of Perla, being oval, depressed, with long oval lateral eyes. These two authors disagree as to the fore legs (Dana), Mr. Scudder calling the parts so designated by Professor Dana, the head. Gerstaecker states his opinion that Miamia is without doubt a EPHEMERID^. 593 Mr. Scudder has more recently described in tlie Paleon-tology of the Illinois Geological Survey, iii, p. 5GG, two otherforms of this group. He remarks, the two specimens beforeme, with wings better preserved than in the individual of Mia-mia Bronsoni, prove-that my delineation of the conjecturalparts of the wing structure of the Paloiopterina was in parterroneous, and give evidence of a closer relationship of thePaloeopterina to the ancient Termitina than I had supposedpossible. A second species of Miamia from Morris, Illinois,he calls M. Danm (Fig. 574 ; all the specimens occurred inballs of iron stone). It is four-fifths smaller than M. Bron-soni. He also remarks, the other fossil which I would referto the Palmopterina is Chrestotes lapidea (Fig. 575). Thegenus differs from Miamia in the shortness and rotundity ofthe wings, a
