Pale olivaceous dial), 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 submargiflal 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 brown. The 

 sub-basal spot on internal margin i.-. bordered ourwardly with white, and there are 

 olivaceous cloudings over the whole surface of the wing. The secondaries are pale 

 drab, with a brown dash on the abdominal margin, 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 ol 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 ba-e. Thorax, 

 antennae, legs and abdomen concolorous. y. In this sex, the whole of 'the. markings

. Primaries 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 indicated 

 by a pale streak, suddenly dentate on internal margin, and almost obsolete on the 

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

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

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

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

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

 teeth between the nervures. Fringe black, except at the nervures, 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!;^ bear a lunate 

 spot, open in the centi e, and showing ground color. 'I he abdomen is smoky above, 

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

 on costa, and posterior margin of primaries. Legs yellowish, ringed with black.

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

 the fringe marked w iih black. The underside also i- yellow ish white throughout, the 

 black marking* of primaries being faintly shown. In one specimen the ground 

 color is clear white with the markings all brownish black, giving the insect a very 

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