The palpi are rather long and porrected considerably in front of the head, the second joint is elongate- JeA.Ai'^ Cct^iM. 

 clavate, and the terminal joint is small, and not concealed ; the head is tufted in front, but the most distinctive 

 character of the group consists in the deep semicircular notch in the middle of the costa of the fore wings. 



Species 1. — Teras emargana^ — (Plate XCVII., Fig. I) — Measures 9 or 10 lines in expanse; fore wings 

 with the basal portion pale ochreous, waved with slender transverse brown streaks of variable length, and the 

 apical portion chestnut-brown, with pale ochreous spots towards the apex, which is arranged in transverse lines ; 

 the costal notch is deep and slightly sinuated ; hind wings buff-brown, slightly reticulated towards the costal 

 and apical parts. Taken in woods in July and August, but rare.
