201. Polyptychus orthographus spec. nov. (I'l. I. f. '.», S). 



S. Smaller tiian tri.-<ecta, more buliisli in tint, liead and jironotum without 



dark brown mesial line ; palpus paler at tiie end than at the sides. Forewing, 



ahore, with a pale, short, subbasal line, parallel with tlie antemedian line, which 

 is more straight than in triaecta ; stigma prominent, lirown, with pale centre ; post- 

 discal line more curved ; a distinct line of lunules between discal and postdiscal 

 lines ; ape.x of wing much less produced and hinder angle more acute than in 



tri»ccta. Hindwing: fringe rather more extended white between the veins, 



disc paler. 



Undo-fiidr : instead of tlie entire, non-deutate, postdiscal line of //-/.scffa there 

 are iu orthoqvaphnti two dentate lines, the external one accentuated by dots upon 

 the veins and situated nearer margin than the line of trisecta, esjiecially in the 

 apical region of the hindwing ; the posterior veins of liotli wings dotted with white 

 outside the j)ostdiscal line. 



Palpus broader at end than in trm'cta, joint somewhat open. Si>urs long, 

 very unetpial, but decidedly shorter than in trisecta, the long terminal spur of the 

 hindtibia shorter than the tibia, the latter shorter than the first tarsal segment ; 

 abdomen without spines, except at the edges of the segments. R- of hindwing from 

 centre of cell. Tenth tergite (PI. XXV. f. 9) long, as in tr/si'cta, slightly dilated 

 at the end; sternite truncate, with the angles rounded. Clasper (PI. XXXlll. 

 f. 19) broadly sole-shaped ; outer surAxce not scaled dorsal ly, the naked area 

 densely covered with minute elongate granules ; eighth tergite with friction-scales 

 as in trisecta ; harpe witli three processes instead of two, the ventral one the 

 broadest, the inner surface of all covered with short bristles ; the upper basal process 

 homologous to the short tooth of the harpe of trisecta. Process of penis-sheath 

 (PI. XXX. f. 39) comparatively shorter than in trisecta, not dilated apically. 



$ and early stages not known. Length of forewing : 33 mm.
