produced into two broad processes : the ventral one slightly curved upwards, concave, 

 the upper one obliquely truncate, with a tooth at the dorsal edge, botli processes 

 covered with very short bristles on the inner surface. Penis-sheath (PI. XXX.

 Bruxelles, liere figured. 



■Jol. Polyptychus orthographus spec. nov. (PI. I. f. 9, c?). 



S. Smaller than tii.secta, more bufKsh in tint, liead and pronotum without 



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



abone, with a pale, short, subbasal line, parallel with the antemedian line, which 

 is more straight than in frisecta ; stigma prominent, brown, with pale centre ; post- 

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

 lines ; aj)ex of wing much less jiroduced and hinder augle more acute than in 



tn'gecfa. Hindwing: fringe rather more extended white between the veins, 



disc paler. 



Uiifh'r.tit/r : instead of the entire, non-dentate, postdiscal line oi trlxecta there 

 are in orthogvnphus two dentate lines, the external one accentuated by dots upon 

 the veins and situated nearer margin than the line of frisecta, es]iecially in the 

 apical region of the hindwing ; tlie posterior veins of both wiugs dotted with white 

 outside the postdiscal line. 



Palpus broader at end than in frisecta, joint somewhat open. Spurs long, 

 very une(pial, but decidedly shorter than in frisecta, 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. Tentli tergite (PI. XXV. f. '■)) long, as in frisecta, slightly dilated 

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

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

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

 as in frisecta ; harpe with three processes instead of two, the ventral one the 

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

 liomologous to the short tooth of the harpe of triseeta. Process of penis-sheath 

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