A REVISION OF THE OEIENTAL HESPEEIID^. 191 



$ . Differs from the male in wanting the sex-mark and in having the pale spots 

 proper to the underside more strongly developed, and consequently the postmedian 

 series appears faintly on the costal portion of the upperside of the fore wing. 



Expanse 21-21J mm. 



Hab. Palnai hills (Castets) ; Peermaad, Travancore. 



Described from four males and one female. Of the species known to us this 

 comes nearest to A. jhora, de Nicev., from which, however, it differs in the form 

 of the tegumen as well as in the spotting of the wings.

6 . Upperside pale umber-brown without markings, a few greyish-yellow scales 

 near the base of the fore wing towards the costa ; on the hind wing a line of long 

 grey hairs along the basal two-thirds of vein 1 b ; sex-mark on the fore wing a 

 small inconspicuous fold of raised scales in cell 1 a next vein 1 a near the middle. 

 Underside : fore wing pale umber-brown ; the apical region similar to the hind 

 wing, and I aving the usual postmedian series of pale spots indicated by very indistinct 

 pale spots in cells 5-7 or 5-8 ; a pale anteciliary line : hind wing grey-brown, with 

 a very faint greenish tinge by reason of the close sprinkling of yellowish-grey 

 scales on the pale brown ground ; a pale anteciliary line ; the usual postmedian 

 and subterminal series of pale spots are only indicated by a few very indistinct pale 

 spots. Fringes pale grey, the shorter scales grey-brown. Antennae above black, 

 minutely spotted with yellowish ; beneath greyish yellow, the shaft spotted with 

 black. Second joint of palpi clothed with whitish-grey and black hairs intermixed. 

 Body above concolorous with the wings, beneath with yellowish-grey pubescence. 

 Legs with yelloAvish-grey scaling. 



Tegumen as in A. discreta and A. jhora. 



Expanse 21 mm. 



Hab. West Java. 



Described from a single male kindly sent to us by Herr P. C. T. Snellen with 

 the name Apaustus discreta, Plotz. In general appearance it comes nearest to 

 the insect from the Khasia hills and Burmah, which we identify as discreta, Plotz, 

 originally described from India; but the latter species, in all the specimens which 

 we have seen, has the pale pattern on the underside well marked and constant.
