the d palpi are black or brown towards the end, and the antennae are 
brown ringed in the d ; in the $ antennae and palpi are brown; the 
yellowish proboscis is also brown at the tip, and the wings are yellowish, 
especially along the costa, with pale veins ; the tarsi are brown.”

Note. —I have a note on a specimen of this European species, 
but unfortunately the specimen has been attacked by mites and 
irreparably damaged. It was taken at Kingston-on-Thames in 
1885. Both Stephens and Walker also record it from England, 
Meigen and Schiner from Germany, Gimmerthal from Russia, 
Fabricius from Scandinavia.
