hvalinc, the apex of the snbmarg'inal vein blackened and with 

 a faint trace of infnscation below on the basal side of this dark 

 line, stigmal vein (except its apical i)rolongation) mostly in- 

 fnscate, the infnscation being continned narrowly downwards, 

 the whole forming a curvate dark marking, reaching the middle 

 of the width of the wing. Antennae 7-jointed, with a distinct 

 ring joint; the single funicle joint is elongate, and when seen 

 in its widest aspect is not mnch less than twice as long as wide, 

 the jK'dicel is very elongate, being mnch longer than the ring 

 joint and fnnicle together, bnt not twice as long as the fnnicle 

 joint alone. The clnb is snbeqnal to the pedicel, ring joint and 

 fnnicle together, its basal joint at its widest is nearly as wide 

 as long, and is abont eqnal in length to the following joint, 

 the apical joint is pointed and has a spinose apical jirolongation 

 on each side; the clnb is mnch wider than the fnnicle joint. 

 The front wings are narrow, abont three and a half times as 

 long as their greatest width, the longest cilia abont two-thirds 

 as long as this width, the discal ciliation is irregular and not 

 dense, terminating beneath the stigmal vein, basal of which the 

 wing is almost free of hairs. The marginal vein is very long, 

 fnlly as long as the snbmarg'inal, the stigmal is moderately long 

 and is excised at the apex, so as to form two processes, one di- 

 rected transversely to the wing, the other directed apically. The 

 hind wings are covered with microscopic ronndish infnscations 

 of the membrane, rendering them notably darker than the front 

 ones ; they bear a single row of npright setae placed well within 

 the costal margin, but mnch nearer this than the dorsal, in ad- 

 dition to the longer hairs on or close to the costa ; the spine 

 bearing the hooks, bf which the wings are united for flight, is 

 elongate and very strong. Abdomen stout, not elongate. Length 

 .75 mm.
