A seemingly common species with little variation. Although no 

 comparison has been made with European specimens, I have no 

 doul)t as to the determination. 



cf, 9. Dark, blackish; anterior frons, face, cheeks, antennae, except third 

 joint above, palpi, halteres, fore coxae, middle and hind legs, except apical 

 bands on femora and tibiae, pale. Wings as figured (fig. 18). Opaque to 

 subopaque. Frontal stripe not extending beyond middle of frons. Thorax 

 and abdomen more or less cinereous. Mesonotum more or less narrowly 

 vittate; pleural stripe distinct. Fore legs except coxae and last tarsal joint, 

 black. Mesopleura entirely bare. Length. — 2.5 to 3 mm. 



Originall}^ described from Europe, and apparently truly repre- 

 sented in our fauna. It is easily recognized by the wing design.
