distal than anteriorly ; two undulate lines from costal to inner margin, beginning 

 between cell .and S( '•' ; all these ver}' indistinct ; a more distinct, even, line from tip 

 of wing to lower angle of cell coutiuned along M to near base ; the line is thin and 

 has a pale hinder border, recalling the midrib of a leaf; the veins are faintly 

 streaked and bordered pale ; disc behind apex of cell more cinnamon ; stigma black, 



small lint consjiicnons ; inner margin with a darker basal triangular space. 



Hindwing of the dark colour of the tliorax, costal and abdominal margins and upper 

 part of distal margin cream-colour. 



Underaidi' dirty cream-colour. Forewing : middle of basal half fnscous ; a 



line from apex to R', wliicli it reaches mm. from cell, thence continued posticad 



to M-, which it reaches 6 mm. from end, forming a very obtuse angle at R-'. 



Hindwiug : abdominal area shaded with fnscons : a faint trace of a discal transverse 

 line, and a thin oblique apical line. 



Tenth tergite long (PI. XXV. f. 25, Xt) divided into two lobes ; the sternite 

 (A'») broadened aiiically, divided into two diverging lobes. Clasper (PI. XXXIV. 

 f. 12) narrowed towards end, much more elongate triangular than in the species of 

 Poli/pti/c/iux, with long narrow scales at the apex ; no friction-patch (the clasper 

 is much rubbed, like the eighth tergite, in the only specimen known to us) ; there 

 is no projecting harpe. Above the penis-fiumel there is a pair of curved ]irocesses 

 (?;) which bear setiferous tubercles. Penis-sheath withont external armature, but 

 from the interior projects a double blade of chitiii, notched, and beset with some 

 bristles (PI. XXXIV. f. 12).

cJ. Tongue very short and weak. Genal process small. Palpus smoothly 

 scaled, joint not quite open. Antenna (c?) thickest in basal fifth, distal segments 

 scarcely grooved, ventral outline of segments (side-view) straight, iienultimate 

 segment longer than high, last one three times as long as high. Abdomen long, 

 tergites without sjtines at the edges, the scales rejjresenting them hi- or tridentate, 

 rather tawny. Sjmrs short, not spinose, one pair to hiudtibia, longer spur as long 

 as the tibia is broad ; pulvillus and i)aronychium present. Clasper without friction- 

 pati'h, but eighth tergite internally with small erect scales at the inner edge. Apex 

 of forewing very strongly produced, hooked, apex of hindwing pointed at SC-, anal 

 angle produced, distal margin concave between R' and anal angle, D- more than 

 twice as long as D^, not strongly oblicpie, U' transverse, lower angle of cell obtii.ie.

Differs from PolypUjchus in the liindtibia having only one pair of spurs ; from 

 Marumba in the obtuse lower angle of the cell of the hindwing, from Luothonia in 

 the presence of the parouychium. Wiug-form peculiar.
