16. Ptychopoda albiflava sp. nov. 



Fm'evnnfjs: white, with very sparse black atoms; the lines pale yellowish 

 ochreous ; the first curved at one-third ; the central and exterior both outcurved round 

 cell, and somewhat strongly inangulated opposite cell ; exterior line and marginal 

 area yellowish ; a row of minute black marginal dots ; fringe yellowish ; cell-spot 

 large, black. 



Hinchvings : similar. 



Face and palpi dark brown; head, thorax, and abdomen pale ochreous. Under- 

 side whitish ; the marginal spots of both wings only shown. 



Expanse of wings : 1 8 mm. 



One ? from the Khasias, April 1 894. 



Resembles P. complanata, but smaller, whiter, with the apex of forewings more 

 rounded. 



17. Ptychopoda complanata sp. nov. 



Foreivinga : white, with pale ochreous-brown markings ; the dark dusting very 

 minute and often obsolete, except along costa ; basal, inner, and central lines oblique, 

 rather thick, and curved only towards costa ; exterior line double, forming an oblique 

 fa.scia with wavy edges ; hindmargin ochreous brown like the lines, so that the sub- 

 marginal wavy space is distinctly pale ; fringe concolorous, with a row of exceedingly 

 minute dark dots along margin. 



Hindxvings : like forewings ; a minute black cell-spot in both. 



Face and palpi dark brown ; collar pale brown ; head, thorax, and abdomen 

 whitish ochreous. Underside with the outer lines of forewing expressed, the base and 

 disc suffused with fuscous ; hindwings wholly whitish. 



Expanse of wings : 24 mm. 



Abundant from the Khasias, April 1894 ; also from Darjiling. 



All the Darjiling examples are devoid of dark dusting, while most of the Khasia 

 specimens have it more or less developed. 



Allied to aspilataria Wlk., which, however, has no cell-spots. 



18. Ptychopoda consimilata sp. nov. 



Forewings : ochreous, dusted thickly with blackish or fuscous ; the lines pale 

 brown ; exterior line much nearer hindmargin than in P. inangulata, and marked by 

 black points on veins ; not inangulated, as in inangulata, beyond the cell ; sub- 

 marginal line indistinct ; a row of black marginal points between the veins ; fringe 

 ochreous, with a row of smaller dots opposite the veins. 



Hinchvings : the same. 



Face and palpi dark brown ; collar pale brown ; head, thorax, and abdomen 

 ochreous ; abdomen sometimes with dorsal black spots. Underside pale, with the 

 exterior lines strongly marked ; forewings suffused with grey. 



Expanse of wings : 24 mm. 



Numerous from the Khasias, January to April. 



Distinguished from inangulata by the different course and position of the outer 

 Unes. 



19. Ptychopoda grisescens sp. nov. 

 Foreivings: mouse-grey, with darker dusling; first lino black at one-fourth, 

 toothed outwards on subcostal, median, and submediau veins ; second line from middle
