11. Track, spartodeta, n. sp. 



Minor, alis ant. dilute griseo-ochreis, linea antica transversa rectangulata, 

 altera postica sinuata, maculaque costse media elongata saturate fuscis, 

 macula disci parva ferruginea ; post, dilute griseis. 



Female. — 15 mm. Head and palpi pale greyish-ochreous, terminal joint 

 of palpi with two obscure dark fuscous rings, second joint obscurely banded 

 with dark fuscous. Antennae fuscous. Thorax pale greyish-ochreous, mixed 

 with dark fuscous. Abdomen grey. Anterior and middle legs dark fuscous, 

 with pale greyish-ochreous rings at apex of joints ; posterior legs whitish- 

 ochreous, slightly infuscated. Forewings elongate, rather narrow, costa 

 moderately arched, apex nearly pointed, hindmargin hardly rounded, very 

 oblique ; greyish-ochreous, somewhat mixed with dark fuscous ; markings 

 cloudy dark fuscous ; a small spot at base of costa, and another on inner 

 margin near base ; a transverse line from ^ of costa to ^ of inner margin, 

 forming a right angle outwards in disc, where it is mixed with ferruginous, 

 and preceded near inner margin by a tuft of raised scales ; a narrow elongate 

 spot along central third of costa, connected with a raised ferruginous spot 

 in middle of disc, beneath which is a raised tuft and some irregular dark 

 fuscous spots ; a transverse line proceeding from costa at f obliquely 

 inwards, a little beneath costa sharply bent outwards, and thence curved to 

 anal angle; three or four small cloudy marginal spots round apex: cilia 

 pale greyish-ochreous, mixed with dark fuscous. Hindwings pale grey, 

 apex and hindmargin darker ; cilia grey- whitish, with two faint grey lines. 



This and the three following species are closely allied, and are most 

 easily distinguished from one another by the angulation of the anterior 

 transverse line ; in this species and T. galaxias it forms nearly a right angle, 

 but in this species the head and forewings are greyish-ochreous, whilst in 

 T. galaxias they are white ; the apex of the forewings is more pointed than 

 usual.

12. Track, nyctopis, n. sp. 



Minor, alis ant. griseis, striga antica transversa leviter flexa nigra, 

 interdum 'fascia lata pallidiori, macula costas media elongata lineaque postica 

 transversa sinuata saturate fuscis ; post, griseis. 



Male, female. — 13^-17 mm. Head and palpi whitish-grey, second joint 

 of palpi externally suffused with dark fuscous. Antennae grey. Thorax 

 whitish-grey, sometimes mixed with dark fuscous. Abdomen grey. Legs 

 dark fuscous-grey, middle tibiae with central and apical whitish rings, all 

 tarsi with whitish rings at apex of joints. Forewings elongate, rather 

 narrow, costa moderately arched, apex rounded, hindmargin very obliquely 

 rounded ; grey, coarsely irrorated with dark fuscous ; base of costa, and a
