It is very onrions that in tliis spocies and several otbcrs the variation in 

 size is eonsideralile, and esi)eeiall}- that the intermediate sizes seem to he rarer 

 than the more extreme individuals. We have here cases of imperfect dimorphism. 

 The name oi tmnintnica is based on a very small specimen.

(??. End-segment of antenna longer than th ■ three preceding segments 

 together. In colour similar to tiffictitia, forewing nearly as in yi;rans ; essentially 

 different from both in the abdomen being marked -viithfoiir pale cadmium-yellow 

 side-])atches which are separated from one another by brownish black basal 

 patches ; the second and third patch the largest ; seventh tergite as in affictitiri, 

 without the extended white base of (/i/rans ; abdomen below and wings rather more 

 tawny than in affictitia, the former with vestiges of pale mesial patches, side-tuft 

 of fourth segment buffish, not white. 



Wings, ahoce. Forewing : lines not prominent, two auteraedian ones almost 



straight, first twodiscal ones much less curved than in gi/rans. Hindwing russet- 



mnmmy-brown at base, an ill-defined distal border of the same colour, middle of 

 wing paler, especially between apex of cell and anal angle, where there is generally 

 a distinctly yellow shade if the long yellow hair-scales are not rubbed away ; in 

 fresh si)ecimens the whole median area is covered with snch yellow hair-scales. 



Undersidi' : basal area of forewing, especially at costal vein, shaded with 

 yellow hair-scales : abdominal area of hindwing more extended yellow than in 

 yi/runs. 



S. Tenth tergite obtusely pointed, not dilated laterally before end; sternite 

 black distally, narrow, sides jiarallel, end rounded, somewliat incrassate. Clasper 

 ivith friction-scales ; harpe short, acutely triangular, ventral edge denticulate 

 (I'l. L. f. 34). Process of penis-sheath (V\. JiVI. f. 10) ending in a long point, 

 distal edge with a few teeth in middle, jiroximal edge dentate at least in basal 

 half, base projecting distad. 



Jjength of forewing varying from lii to ~:) mm. 



lldl). Sarabawa, eastwards to Queensland.
