A new Genus of Cyrtidae from South America (Dip.).* 
By FRANK R. CoLg, Scientific Assistant, United States 
Bureau of Entomology. 
In preparing a monograph of the Cyrtidae of North Amer- 
ica, the writer has had access to the collection in the National 
Museum. In this collection of Cyrtidae there are a few speci- 
mens frcm Chile, South America, collected by C. E. Reed. 
One specimen labeled Lasia dimidiata seemed to be so entirely 
different in general appearance from any known species of 
that genus that I took the trouble to examine it more closely. 
This specimen is of an undescribed genus, quite far from Lasia, 
and belongs in another subfamily—the Oncodinae. The ab- 
domen has evidently been broken off and is glued on to the 
thorax at an impossible angle. One of the front legs is broken 
off in the middle of the femur and the last four joints of the 
tarsi are broken off from the other front leg. 
VILLALUS new genus. 
Head hemispherical and composed almost entirely of the 
eves. Eyes touching from vertex to antennae and from small 
space at antennae to the tiny mouth parts. The mouth parts 
are rudimentary and the facial triangle much reduced and on 
the under side of the head. There is no proboscis. The eyes 
are thickly covered with very short pile. Antennae small and 
apparently two-jointed (see Fig. 3), the first joint being sunken 
in the head; second joint cylindrical and not much longer than 
broad ; the third joint radish-shaped and with a slender style 
which is enlarged slightly at the tip and ends in a microscopic 
bristle. Ocellar tubercle rather small, with three ocelli, form- 
ing an equilateral triangle (see Fig. 4). Odcciput slightly 
swollen and with short hairs. 
Thorax large and swollen in appearance with rather short 
recumbent hair. Upper pleurae swollen and covered with 
hair. Humeral callosities quite large but widely separated. 
Post-alar callosities of medium size. Scutellum rounded and 
about as long proportionately as in Oncodes. Legs including
