In the ? nil the red tints are replaced by dark purple, except the face and spot 

 on vertex, which remain as in the c? ; the lustrous scales more conspicuous. 



Expanse of wings : <S, 22 mm. ; ?, 20 mm. 



A good series of both sexes. 



The antennae of the S are beset with long thin fascicles of cilia. In forewing 

 the outer margin is vertical to below vein 4, then iubent. 



Subfamily TRICHOPTEUYGINAE. 



162. Sauris? bigriseata spec. nov. 



Forewing : pale green, with deeper green cross-lines ; four in basal area, broad, 

 the outermost dentate, the second marked with blackish ; the narrow bands preceding 

 and following central fascia pale green with an angnlated darker green line through

 dark green before the margin ; marginal black spots large, followed by pale spots in 

 the fringe, which is pale green in the yellower green example, and grey in the other. 

 Along the two folds, beyond middle of wing, the lines are marked with black and 

 the intervals partially rilled in with grey scales ; several of the lines are also marked 

 with black along the subcostal vein. 



Hiudwing : dingy pale grey, darker at base and along outer margin. 



Underside of forewing pale olive-green with indistinct streaks of brown-red

 inner margin beyond middle ; at two-fifths of costa an outwardly oblique brownish 

 triangle with dark margins ending in the oblique linear cell-mark ; beyond middle 

 a band of four dark lines, forming the outer band of central fascia, irregularly 

 twisted and angled, the outermost acutely below veins 6 and 4 ; above the middle 

 this baud is darkened with grey ; the pale band beyond with a grey thread in the 

 costal half only ; submarginal line double, dark, irregularly crennlate ; a nearly 

 marginal black line, thickened above between veins and paling below; fringe white, 

 with distinct square black spots beyond veins in the basal half, connected at base 

 above middle of wiug by a fine dark line ; on each side of vein 5 the submarginal 

 line is traversed by a black dash, and above vein 6 the marginal area is pale 

 brownish. 



In the ? the centre of the outer band and the submarginal line are brown-
