In a culture of flies sent to Dr. O. A. Johannsen by Dr. C. W. Metz of Johns Hopkins, there proves to be a new species of Sciara. This insect is being used in research in genetics and it was thought best to have the insect described as soon as possible. According to Doctor Metz, “The original female under No. 6986, was collected by Mr. J. P. Reynolds from Sykes' greenhouse at Guilford, North Carolina, December 5, 1933.”
