exterior line sli-rhtly curvwl, but not denticulate ; tbe cellsjiot anil dots in the 

 fringe much smalloi- and fainter. 



Ilimlicim/s: witli antemcdian and iiostmcdian Xuw.a curved, but not crenulate. 



Underside with the two lines of both wings concise and not denticulate. 



The pencU of liair on the hind-tibiae of tlie S yellowish ochreous as in 

 Pt. actiosaria. 



Expanse of wings : IT mm. 



A pair from Sabathn, N.-W. India, August 1889, 



Agrees with P. semisericea Warr., from the Khasias, in being paler and 

 smaller than actiosaria ; but in xemisericea the tuft of the hind-tibiae is blackish 

 internally. 



26. Ptychopoda robusta sp. uov. 



Foreicings: pale ocbreous, overlaid with yellower ochreous scales; the costa 

 narrowly ochraceons ; cellspot large, brownish ; the lines yellowish ochreous ; 

 inner and median lines very obscure ; outer line at four-fifths, slightly curved and 

 parallel to hiudmargin, followed by a paler band ; beyond this the marginal area 

 is again yellower ochreous, traversed by a faintly discernible paler snbmargiual line ; 

 fringe ochreous, with faint brownish dots at base beyond the veins. 



J/iml/ciiiffs : the same. 



Underside paler ; the cellspots and outer lines discernible. Face and palpi 

 brownish above, ochreous below : vertex, thorax, and abdomen like wings ; collar 

 ocbraceous, like the costal edge ; antennae with the shaft pale, the cilia ochraceons. 

 Tuft of hair on hind-tibiae ochreous externally, dark fuscous internally. 



Expanse of wings : .'4 mm. 



One (J from Negros, Philippines, March and April isyij (.J. AVhitehead). 



The antennae are subserrate with very long curled cilia ; the whole insect has 

 a much more robust appearance than actiosaria Wlk. and its allies, to which it is 

 evidently most related. 



2'. Ptychopoda sextinotata sp. uov. 



Forewings : dingy ]iale grey, slightly tinged in parts with darker ; the lines 

 all parallel to each other and to tbe hindmargin which is oblique ; the inner at 

 one-third curved, marked with three blackish spots on veins ; median distinct, 

 from two-thirds of costa to middle of inner margin, denticulate and sinuate, 

 incurved below middle ; outer line from four-fifths of costa to three-fourths of 

 inner margin, denticulate, sinuate inwards beyond cell, the teeth with dark points 

 on the veins, that on vein (5 conspicuous ; the shade preceding the submarginal 

 line exactly parallel to tbe outer line, the outet' shade not sinnate beyond cell, 

 so that the submarginal pale line is broader and more distinct beyond cell : a 

 marginal series of distinct black dots ; fringe concolorous : cellspot blackish. 



llindwinys : similar, the median line becoming antemedian ; the tooth on 

 Vein of outer line prominent as in forevrings. 



Underside grey, without distinct markings except the marginal dots. Face 

 and palpi externally fuscous brown ; collar dark grey ; vertex and antennae 

 whitish ; thorax and abdomen like wings. 



Expanse of wings : 1 7 mm.
