SOME NORTH AMERICAN SPECIES OF 
CH^ETOPLEUROPHORA (DIPTERA, 
PHORIDiE) 
By Charles T. Brues

A collection of Phoridae recently sent to me from Cornell 
University for identification contains an interesting new species 
of Chaetopleurophora. To the description of this which is given 
below, I have added generic references for several other Ameri- 
can species. 
Choetopleurophora Schmitz. 
Chaetopleurophora rufithorax sp. nov. 
2 . Length, 2.0 mm. Black; the thorax above reddish brown, 
lighter at the extreme sides and indistinctly so as a streak on 
each side of the median line; pleurae also brownish; scutellum 
paler, except at the base; front and middle legs entirely pale 
yellowish; hind legs pale at the base, blackened beyond the 
basal third of the femora and again brown on the tarsi; palpi 
fuscous. Halteres whitish. Wings weakly, but distinctly in- 
fuscated; heavy veins brown. Front minutely roughened, not 
shining; quadrate, or slightly longer than wide. Frontal bristles 
long and stout; postantennals inserted very near together; 
lower frontal row equidistant, the lateral ones very close to the 
eye-margin and slightly higher than the median ones ; preocellar 
row of four forming a straight transverse line, equidistant from 
the lower row and the ocellar row. Median frontal line faintly 
indicated, ocellar tubercle distinct. Eyes pubescent. Antennae 
unusually small, rounded; with a long, sparsely pubescent 
arista. Palpi very small, with moderately long bristles at tip, 
but those along the lower margin are weakly developed. Meso- 
notum subshining, with conspicuous minute hairs; one pair of 
dorsocentral bristles set very near to the base of the scutellum; 
sides of the mesonotum bristly behind, but only a couple of 
these bristles are long and stout. Propleura with two small, 
but conspicuous bristles at the posterior margin next to the
