1. In his Coleopterological Notices, V., p. 594, Mr. Casey described a new genus of Aleocharini under tire name of Myrmobiota (crassicornis, Cas., n. sp.) as allied to Homœusa, Kr. The only specimen was captured at Iowa City (Iowa) by Mr. H. F. Wickham. Some time afterwards I received three specimens of an insect very like our Homœusa, under the name of Myrmobiota crassicornis, Cas., one directly form Mr. Wickham (captured at Iowa City, June 6, 1896), two through the kindness of Rev. P. J. Schmitt (captured by Wickham at Iowa City, bearing Wickham's number, 9561). After having compared this species attentively with our Homœusa acuminata, I could not doubt that it belonged to the same genus as the latter. I publisherd a note on this subject in the Tijdschrift voor Entomologie, XLI., 1898, p. 11, declaring Myrmobiota to be the same genus as Homœusa.
