( 160 ) 



Antennae with basal segment long and erect, ending in a tnft, below which the 

 shaft leaves it at right angles and is depressed ; the same occurs, in a modified 

 degree in the ?; forehead with pointed scale-tuft below; palpi porrect, the 

 terminal segment depressed, much longer in ? than S \ hindtibiae of $ long, with 

 two spars, of which the inner is three times as long as the outer ; of ? with three 

 spurs as in Adeta and Aniserpetes. 



Type : Sillopkora albiviridis spec. nov. 



This genus partakes somewhat of the characters of Pycnoloma and Ptychotheea, 

 this latter exhibiting the development of the cell furrow in an extreme degree 

 while the former shows a similar unusual development in the base of cost a of 

 hiudwing. 



loo. Sillophora albiviridis spec. nov. and ab. completa nov. 



Forewing: whitish green ; crossed by nnmerons wavy dentate greenish lines ; 

 the central fascia and praesubmarginal shade always darker and mixed with 

 fuscous : the fascia is subobsolete below middle, and less marked in the hindwing ; 

 marginal lines finer, interrupted ; fringes mottled. 



Head, thorax, and abdomeu whitish ; the patagia and metathorax mixed with 

 "reeu aud grey ; the second dorsal segment with a grey belt, the rest of abdomen 



pale. 



In the aberration completa the interruption of central fascia of forewing below 

 middle is more entire, at the same time the upper part of I'aseia is much darker : 

 while in the hindwing the fascia is interrupted at costa and complete and blackish in 

 inner-marginal half ; and the middle segments, sometimes the whole, of dorsum are 

 blackish. 



Expanse of wings : 16— IT mm. 



3 $$, 8 ¥ ?, including U,-'??, of the aberrati 



tion. 



Stenista gen. nov. 



Forewing: triangular ; costa straight, curved shortly at base and apex ; outer 

 margin as long as inner, more oblique below vein 3. 



Hindwing : of S small aud narrow ; outer margin curved from apex to 4, 

 which is slightly prominent, crenulate from 4 to ■', and again from :( to 2, this last 

 crenulation being almost in line with the shortened inner margin, which immediately 

 follows vein 2, the submedian fold and vein 1 being absent ; vein 2 from near 



base of cell. 



On the underside the costal half of hindwing is clothed with rough semi-erect 

 scales, the costa itself being well curved ; hindwing of ? normal. 



The rest as in Tephroclystia. 



Type : Stenista commixtilinea spec. nov. 



156. Stenista commixtilinea spec. nov. 



The description given in Nov. Zool. xiii. p. 132 of the supposed ? of Tripteridia 

 albimixta really refers to the ? of this species; the 6 agrees witli it, in the 

 forewing, but the pale lines are greener, and the blurred space to margin between 

 veins '■'} and 4 is greenish ochreous aud not bntf. 



Hindwing: cream-colour, with patches of lilac-grey scales at outer margin 

 below middle.
