A new Genus of Gyrtidae from South America (Dip.).* 



By FRANK R. COLE, 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 from Chile, South America, collected by C. E. Reed. 

 One specimen labeled Lasia diniidiata 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 

 eyes. 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). Occiput 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
