The figure of the head of EpicereUa {Dipt. Exot., Suppl. Tab. xxvii.) might perhaps justify the supposition that the genus belongs to the Orlalida^; n(!V(!rtheless I think it more probable either that the frontal bristles, characteristic of the Trypetidse, were broken off in Macquart's specimen, or that they have been omitted in the drawing. Thus I do not dare to express any opinion as to the correctness of the position assigned by Mac- quart to this genus. Gephalia, in the Dipleres Exotiqucs, is likewise put among the Sepaidse instead of among the Ortalidie. Omaluccphala (better Ilomalocephala, at all events, a preoc- cupied name) seems to belong in the vicinity of Selellia, Cado- metopia, etc., that is, in the family Ortalidse. The genus Conopsidca, as Macquart informs us, is founded upon Gephalia femoralis Wied.; in the Suites d Buffon, this same and two more species gave him occasion to establish the genus Michogaater. If these two data be correct, as we have every reason to supnose, Conopt^idea would be a synonym of Michogader; the emendation of the incorrectly formed name Conopaidea thus becomes useless. The erroneous location of Setellia at the end of the Leptopo- ditae is preserved. Ulidia is transferred to the family Lauxan
