each cell. Fore wings with an interior, both wings with middle 

 and discal pale grey bands, all more or less outwardly dentated 

 with black points at the tips of the dentations; submarginal and 

 marginal similar bands without the black points, but there are 

 black points on the outer margins, and black points at the base of 

 the cilia opposite the centres of the interspaces. Under side 

 whitish, with the central and discal bands thin, like lines, and with 

 the black points to the discal baud, and marginal and cilia points 

 as above. Expanse of wings, 1/g in. 



Eleven specimens.

<? . Ochreous grey, irrorated with brown atoms, the irrorations 

 packed together in the upper centre of fore wings, forming a 

 suffused pale brown patch. Both wings crossed by an indistinct 

 and incomplete grey sinuous discal line, with dentations and black 

 points at their tips ; a more or less dentated submarginal line ; 

 marginal black points and black points, at the base of the cilia ; a 

 small black ringlet at end of each cell. Under side whitish, with 

 the cell-ringlets, discal and marginal points, and lines showing 

 through. Expanse of wings, If'j in. 



One specimen.

Streptopteron, Hampson MS., gen. nov. 

 J . Antennae heavily bipectinated ; palpi 

 with the third joint of moderate length and 

 porrect. Fore wing with the apex rather 

 pointed, the outer margin distorted and cut off, 

 so that the lower radial reaches the apparent 

 outer angle, and the three median veinlets 

 reach the margin of a lobe formed by the inner 

 half of the wing ; the five subcostals are given 

 off considerably beyond the cell, the fifth 

 nearest the angle, the first, second, and third 

 at intervals shortly before the apex ; the upper Steeptopteeon. 

 disco-cellular is given off from the upper radial, 

 the lower radial from above the middle of the disco-cellular, 

 the third median from the lower angle of the cell, the first and 

 second medians at intervals before the angle, and all throe rather
