The fifth, sixth, and seventh segmentsgradually decrease in length. The epimera of all the segments are ex-tremely narrow; those of the second and third segments extend but halfthe length of the segment; those of the fourth and fifth segments extendthree fourths the length of the segment; those of the last two segmentsextend the entire length of the segment. *The female is figured.
