edge and the tegulae rufo-testaceous; the greater part of the anterior femora, tibiae and tarsi 

 brownish ; wings clear hyaline, an irregular cloud across the transverse basai and transverse 

 médian nervures, broader behind than in front, one filling the basai three-fourths of the 

 radial cellule, the 2 n( l and yà cubitals (deeper coloured in the former in the middle) and 

 extending more lightly into the discoidals; the 2 nd and 3 rd abscissae of the radius almost 

 equal in length, the transverse médian nervure interstitial; the ist récurrent nervure received 

 shortly before the middle of the cellule, the 2nd at half the distance from the base ; accessory 

 nervure in hind wings received clearly behind the cubitus. Tegulae rufo-piceous. 9 an d cf-

Black, covered with silvery pubescence, the underside of the basai joint of the hind 

 tarsi densely covered with bright reddish golden pile; the apical 2 joints of the hinder tarsi rufo- 

 testaceous ; wings uniformly fuscous, tinged with violaceous, the nervures black, the ist abscissa 

 of the radius as long as the following 2 united, the 2^ about one quarter shorter than the 

 yd and a little shorter than the space bounded by the ist transverse cubital and the ist récurrent 

 nervures; the 2nd récurrent is received before the middle of the cellule. Eyes at the top separated 

 by hardly the length of the 3 rd antennal joint. A narrow, but distinct furrow runs down from 

 the ocelli to the antennae ; there is a distinct furrow on either side of the middle of the 

 front, deep and narrow in the centre, the sides obliquely sloped. Apical joints of palpi dark 

 fuscous. Basai part of metanotum finely, closely transversely striated; a longitudinal keel runs 

 from the base to shortly beyond the middle; the apical slope sparsely obliquely striated on 

 either side of the central furrow, which is narrow and clearly defined; it does not extend to 

 the apex. The abdominal segments are banded with depressed silvery pile, the pygidium with 

 a silvery pile; it is about one half longer than it is wide at the base; the apex is broadly 

 rounded and is about half the width of the base.
