The two genera named are readily distinguished from other Drosophilidse by the shortness of the second longitudinal vein, which surpasses the first but slightly, as the accompanying sketches show. Asteia has been known from the time of Meigen as a European genus, of which four species are recorded in the Palse- arctic Catalogue; it has no posterior cross-vein, and the arista is plumose as in Drosophila. SigaloEssa was established by Loew for a Cuban species S. bicolor (Centuries, VI, 100, 1865); it has a pos- terior cross-vein, and the arista is only microscopically pubescent in most cases, although in frontalis described below it is short- plumose.
The wing figured by Williston, Manual, 1908, p. 300, fig. 7, as a doubtful member of Sigaloessa, belongs to a fly of another genus; his figure on page 311, fig. 7, is correctly named as a Sigaloessa. The Asteia tennis of Walker, Trans. Ent. Soc., n. ser., V, 331, must belong somewhere else; he mentions the posterior cross-vein, which being near the border would also exclude the fly from Siga- loessa. Walker himself gave the genus with a question, but Osten- Sacken dropped the interrogation point, perhaps only a clerical error.

A specimen of Sigaloessaflaveola Coq. is in the author's collection, taken at Lawrence, Kans.
The only other described species,
bicolor Loew, has not been seen.
Asteia is here recorded from North America for the first time. .

Length, 2.4 mm.; of wing, 2.8 mm.
A single female, Chester, Mass., August 6, 1914, collected by C. W. Johnson, to whom it has been returned. A label bears the note, "Eyes green."

face yellow immediately below the antennae, then with a narrow black band, below which is a wider pure-white band, below this again black, which extends to the bucca in less intensity; two small pairs of verticals; one of frontals, close to orbit and above middle of front; ocellars minute; vibrissse distinct. Mesonotum shining brownish-black; pleurae with wide white stripe on upper part, a black one below this, and the lowest part yellow; scutellum pure-white, somewhat swollen, with one pair of divergent, ascending bristles; the remainder of the thoracic chaetotaxy cannot be distinguished in the specimen, and the halteres are wanting.
Abdomen yellow with black bands, but not in condition to describe more fully. Legs yellow, slender.
Wings hyaline, venation as in beata.
