submedian vein united by a short subbasal oblique vein- 

 let to an abbreviated curved longitudinal vein, which is 

 again attached before its extremity to the median vein 

 by means of a rudimentary interno-median veinlet ; 

 secondaries suboval, with nearly straight costal margin ; 

 costal vein fused with the subcostal to beyond the middle ; 

 subcostal four-branched, the first branch being fcu'ked

 exactly as in the primaries, and, excepting that there 

 are only three radials, so are the other veins, with the 

 exception of the submedian, which is simple, as is also 

 the internal vein ; body very long and rather narrow for 

 the family ; the thorax clothed with long matted hairs ; 

 antenna; short, distinctly segmented and ciliate ; palpi 

 long and slender ; legs rather short and thick.
