bronzy scales and long black backwardly-projecting chaetae, 
especially posteriorly and over the roots of the wings; pleurae 
pale brown with some grey reflections ; scutellum with small flat 
brown scales showing violet reflections, forming a large mass on 
the mid lobe, small areas on the lateral lobes, mid lobe with two 
long median border-bristles, then two shorter ones and a few still 
smaller; metanotum nude, deep brown. Abdomen brown,

the first sub-marginal slightly the narrower, its base slightly 
nearer the apex of the wing, its stem not quite twice the length 
of the cell ; stem of the second posterior cell about one and a
