ceous band, probably covered with grey scales ; the last four 
segments have clear white basal lateral spots; venter with 
numerous white scales.

more or less yellow spot at the apex of the tibiae; venter of the 
femora and coxae pale ochraceous; hind metatarsi the same length 
as the hind tibiae ; ungues rather small, equal and simple. 
Wings clear, with brown-scaled veins, scales similarly disposed 
to those of C. pipiens, the second long vein being entirely clothed 
with long lateral scales, also the third and a greater part of the 
fourth, except at its base, and a few occur on the upper branch 
of the fifth ; the first sub-marginal cell longer and narrower than 
the second posterior cell, its base a little nearer the base of the 
wing than that of the second posterior cell; its stem about one- 
fourth the length of the cell, shorter than the stem of the second 
posterior, w T hich is equal to a little more than half the length of 
the cell; posterior cross-vein not quite its own length distant 
from the mid cross-vein; halteres with ochraceous stem and 
slightly fuscous knob.
