iShining ferruginous; thorax with three chestnut longitudinal 

 stripes; a spot on each pleuron and the metanotum more or less 

 brown; the scutellum yellow. The abdomen green, in dried speci- 

 mens brownish aibove, the anal segments flattened, the forceps 

 short and sublanceolate, the arms incurved, and hairy. Palpi and 

 antennae brown, the hairs of the latter lighter at the tip. Legs 

 ])a]e yellow, the tarsal joints usually darkened; sometimes the ex- 

 treme tips of the tibiae are also darkened; fore tarsus of the male 

 delicately but distinctly haired, its metatarsus an eighth longer or 

 at least as long as its tibia. Wings white, the costal veins of the 

 female ferruginous, the crossvein not darkened. Halteres pale. 

 Length 5 to 6 mm. A specimen from New Jersey is doubtfully 

 identified as this species by Johnson (1899). 



I have a purchased specimen, collector unknown, bearing the 



label C. albipennis, Riverton, N. J., but which in reality 

 is not albipennis, but is C. nigricans n. sp.
