O ■ Pale olivaceous drab, with all the marks and lines rather indistinct. There 

 is on primaries an oblique line from near the base of costa to- near internal angle, 

 terminating on a sinuo-dentate submarginal line which runs from costa to internal 

 angle. Between these, there are on -costa two short dashes, an apical spot, and a 

 distinct spot near base of internal margin. These marks are all light Ijrown. The 

 sub-basal spot on internal margin is bordered outwardly with white, and there are 

 olivaceous cloudings over the whole surface of the wing. The secondaiics arc pale 

 drab, with a brown dash on the abdominal margni,. edged above and below with 

 white. Underside has the apex of primaries dark brown with a white streak, and a 

 pale submarginal line. The secondaries have the central portion much darker 

 olivaceous brown, shading in the centre to dark brown, in the form of a broad streak, 

 and limited by a broad and distinct submarginal pale line. Outside of this line the 

 border has a yellowish tint. The abdominal margin is pale at the base. Thorax, 

 antennce, legs and abdomen concolorous. O . In this sex, the whole of the markings 

 above and below, are more pronounced and vivid in color.

r; . Pruuaries very pale greenish yellow, with the black markings in very strong- 

 contrast. The base is pale, and contains a minute black dot. T. a. line nidicated 

 l)y a pale streak, suddenly dentate on internal margin, and almost obsolete on the 

 costa. In front of the line is a dark shade. The t. p. line is oblique from the middle 

 of internal margin, to about 5 mm. from apex, turning rather abruptly as it touches 

 the costa, and surmounted by 3 pale oblique streaks. The median space is thickly 

 clouded with black, leaving the orbicular mark very distinct. Submarginal lifie 

 slightly dentate behind and also shaded with black. The posterior margin has deep 

 teeth between the nervures. Fringe black, excej)t at the nervLires, where it is cut 

 by the ground color. Secondaries smoky, darkest along, abdominal margin. Fringe 

 flecked with white. Head yellowish. Thorax same as primaries, yellowish green, 

 with black markings, those of the disk transverse, while the tegu'ae bear a hinate 

 spot, open in the centre, and showing ground color. The abdomen is smoky above, 

 yellowish at the tip and beneath. Lower side of wings smoky, with yellowish marks 

 on co^ta, and posterior margin of primaries. Legs yellowish, ringed with black. 

 Eyts and anteniiK; jet black. O. The markings of the primaries are much less pro- 

 iiounced than in the other sex, and the secondaries and abdomen are clear white, 

 the fringe marked with black. The underside also is yellowish white throughout, the 

 black markings of primal ies being faintly shown. In one (^' specimen the ground 

 I. ulor is clear white with the markings all brownish black, giving the insect a very 

 c I liferent appearance. I cannot however regard it as other than a variety, which 

 may be known as D. /'o/iii.x: n. var. -No. 87. Exp. wings, q 44mm.; O 58 mm.
