16 NOYITATES ZOOLOOICAE XXIII. 1916. 



36. Hemistola fuscimargo sp. nov. 



cJ ? , 38-43 mm. Extremely close to rubrimargo Warr., but larger, the <$ 

 antennal pectinations rather shorter and thicker, less in number,* face reddish 

 brown above, pale below (in rubrimargo more reddish, virtually unicolorous), wings 

 rather less blue, the well-expressed, deeply lunulate-dentate white lines accompanied 

 (the antemedian distally, the postmedian proximally) by very fine red-brown edging, 

 at least in the teeth, minute blackish dots placed on DC 3 at the cell-fold, terminal 

 line and dots in fringe fuscous, not red. Wing-shape virtually the same as in 

 rubrimargo, perhaps very slightly broader, apices sharp. In both the lines of the 

 forewing, the submediau lunule is particularly deep and conspicuous; on the hind- 

 wing the line projects very noticeably at R 3 and M l . 



Naga Hills, Assam, 2 $ 8, 1 ? , in coll. Tring Mus. (ex coll. Elwes). 



37. Pyrrhorachis (?) cosmetocraspeda sp. nov. 



? , 20-21 mm. Face reddish ? (abraded). Vertex white, mixed with rose-colour. 

 Antenna white above. Thorax and abdomen dorsally green, the latter with white, 

 rose-mai'gined spots, the first of which also contains an admixture of rose-colour. 



Forewing with costa slightly more arched and termen slightly more oblique 

 than in typical Pyrrhorachis ; cell less extremely short, DC 3 strongly incurved, M 1 

 not stalked ; green (nearly as in Comibaena, but not quite so bright), costal margin 

 white mixed with rose-colour; discal dot small, rose-colour ; lines indicated by rose- 

 coloured vein-dots, those at hind-margin the largest, especially the postmedian one, 

 which is placed a little beyond the middle of this margin ; postmediau row accom- 

 panied distally by white ones ; termen snow-white, edged proximally by a strongly 

 crenulate dark rose-coloured line (which almost touches termen between the veins) 

 and distally by a rose-coloured terminal line ; fringe proximally rose-pink, distally 



yellowish. Hindiving more elongate than in typical Pyrrhorachis, especially at 



inner margin, termen very slightly bent in middle; postmedian line of rosy and 

 white dots present, the rosy ones smaller than on forewing ; fringe as on forewing. 



Underside whitish green, unmarked. 



Digboi, Assam (L. Brunt), 2 ? ? in coll. Tring Mus. 



Both specimens have lost the hindlegs, but the species is so conspicuous that 

 it is safe to make it known. 



Subfam. STERRHINAE.f 

 38. Antitrygodes pirimacula sp. nov. 

 8, 33-34 mm. Smaller than divisaria Walk., antennal ciliation longer 

 (almost as in agrata Feld.), distal margins scarcely so deeply crenulate (approaching 

 agrata), coloration the same, but with the following differences in pattern : 



Forewinq with the dark green subbasal patch more oblique-edged, central patch 



* In rubrimargo over thirty joints may be called pectinate before they become mere rudiments, in 

 fuscimargo about twenty-two joints. The ? antenna, as in rubrimargo, is simple ; my grouping of the 

 genus in Oen. Ins., fasc. 129, pp. 226, 227, is not quite accurate, having been based in part on insufficient 

 material and erroneous information. 



f I have hitherto employed the older name of Acidaliinae for this subfamily, but as the generic 

 name Aeidalia proves unavailable in the (feomctridae (see infra), it is necessary to revert to Sterrhinae, 

 used by Meyrick (as Sterrhidae), Warren and Hülst. Idaeinae (Idaeidae Moore, Lep. Ceyl. iii. 447) 

 would be older, but is also founded on a name which does not correctly belong to the subfamily (see 

 Trans. City Lond. Ent. Soc. xx. 25). In my opinion Sterrha Hb. is merely a subgenus of Ptychopoda 

 Steph., published probably in the same year (1S26) ; it is not certain that it will not have to be given 

 priority, but in any case it is potentially valid in the subfamily.
