33. Colussa strigata inconstans, subsp. nov. 

 (Plate LXII, fig. 2, ^, fig. 3, ?.) 



c^. Very similar to strigata, B.-B.,* but differs especially in the 

 absence of all costal black from hindwings. Upperside. The 

 two cell-spots on forewing are paler than the ground-colour and 

 thinly ringed with black. The post-discal stripe on both wings is 

 not so heavily marked, and the scalloped line next it on both wings 

 is emphasised by black dots on the veins. The pale area proximally 

 of the submarginal line on both wings is suffused with lavender- 

 grey scaling spread thinly over the yellowish ground-colour. Hind- 

 wing with costal area pale yellow to vein 5. 



Underside pale yellowish sprinkled with black. The second 

 submarginal line on hindwing only indicated by vein dots. 



$. Pale yellowish-brown, thinly scaled. Upperside. Forewing 

 dotted over with purplish scales. An indistinct purplish sub-basal 

 line, a second discal line irregularly curved and crossing cell at 

 vein 3. Beyond cell but nearer to it than to margin, a well-defined 

 deep purplish line slightly convex to vein 2 and then straight to 

 the margin. Parallel to this line a row of dark dots on the veins. 

 A narrow marginal border darker than the ground-colour. A dark 

 spot in middle of cell, a larger round one on discocellulars. Hind- 

 wing with a discocellular spot at upper angle of cell. A faint curved 

 discal line crossing cell at vein 3; a post-discal heavily marked 

 dark purplish line, becoming ill-defined towards costa; a row of 

 dark vein dots placed nearly half-way to margin and narrowly 

 separated from a marginal border of purplish scaling. 



Underside with post-discal lines and vein dots showing through, 

 discocellular spots with a dark ring. 



Head, thorax, and abdomen yellowish-brown, antennae and legs 

 dark bro\\Ti. 



Length of forewing : 37 mm. 



2 c^ c^ and 1 $ obtained. The (^ co-type is a much darker 

 specimen. 



34, Colussa aroa angiana, subsp. nov, 

 (Plate LXII, fig. 4.) 



$. Differs especially from aroa, B.-B.,f in the two transverse 

 lines on hindwing being closer together. General colour pale rufous 

 but the CO -type is much redder. Costa and base paler than rest of
