Genus Notiobiella Banks. (Plate xvi., figs. 22, 2o). 



Banks (1; p..^0). 



Small insects, with well rounded wing-tips, forewing much 

 ongerand wider than hindwing. Forewim/ with onl}' two radial 

 sectors, hoth hranched, and connected by a cross-vein running 

 from the fork of the basal one to near the base of the distal one. 

 llindwiny with false origin of Rs strongly formed, very oblique; 

 Cu., absent. Outer gradate .'^eries completely absent in both 

 wings; the inner series represented by three oi' four cross-veins 

 in forewing, only one in hindwing (connecting Mj to basal branch 

 of lis). Costal space of forewing moi'o or less widened, with the 

 recurrent veinlet present. 



G e n o t y p e, N. nnifa Banks. 



This genus is a highly specialised reduction from a type re- 

 sembling Psychitbiella, by the elimination of the long, outer 

 gradate series, and the loss of one of the two radial sectors arising 

 from near the middle of R in the forewing. 



N. Banks has described five species, N. extrema, K. stigmatica, 

 X. II II ltd, N. ohliqita, and JV. pvetiosa, the last from Fiji, the 

 others from Middle Queensland. None of these species is known 

 to me. Two species from S. Queensland appear to be very dis- 

 tinct from any described by Banks. 



1:5. Notiobiella viridis, n.sp. (Plate xvi., fig. 22). 



Total lenyth :i,/orfiwiny 6-5, hiudtving 3-8, pxpaiistp 13-5 mm. 



Head yellow ; pi/es black ; antennce yellowish shading to 

 brown distally. T h o r a x and A b d o m e n binght yellow. 

 Leys testaceous. W i n g s hyaline, with pale green venation. 

 Forewiny with costal space only of moderate width, but all the 

 cross-veins densely branched along costa; distal radial sector 

 branched only once. All the veins approaching the distal border 

 of the wing divide into two once only, and each branch divides 

 into minute forkings at the margin. Some of the veins near the 

 base are much thickened, particularly M in forewing; Cuj in 

 forewing arches up after leaving cuf.
