11. Trach. spartodeta, n. Sp. 
Minor, alis ant. dilute griseo-ochreis, linea antica transversa rectangulata, 
altera postica sinuata, maculaque coste 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. Antenne 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 dise, 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 $ 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 7. galaxias it forms nearly a right angle, 
put 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.
