Among the new genera lately separated by Theobald from Ædes and Uranotœnia, the differences seem at times puzzling, and without an opportunity to study the types, it is not always easy to feel sure of the position of a new insect. It is also to be noted that in some of these genera the male is unknown, and it may possibly happen that they belong to the class having long palpi in the male. This is very definitely suggested by a mosquito received recently from Bayamban, Pangasinan, P.I., which, while having long palpi in the male, flat scales (no curved ones) on the head, curved scales only on the scutellum, still has the wing characteristics of Uranotœnia.
