* [Dr. Speyer writes that this genus must give way to Daimia Murray, 1874.—L.]

* In a letter received from Dr. Speyer as this is passing through trre press, he desires to make the following correction in this diagnostic feature. The tibial tuft (see also foot of page 126) is not reliable for generic separation. A critical examination made by him of some of the species of Nisoniades, has shown its presence in Persius and, Icelus; in the latter, quite strong. Brizo, altholgh so closely related to Icelus, is without the tuft. The detection of this marked difference in these trvo allied species, establishes their specific value, which has been questioned, and also shows that the presence or absence of the tuft is only of specific importance.—L.
