S. Tenth tergite l)riia(lcr in the iniiKllc tliaii in innarhi, the ajiieal sinus not so 

 deep, the lobes notched laterally, witli a tootli proxinially of the notch, nearly as in 

 sjierchiua ; sternite nearly as broad as in maacin, suddenly narrowed to a short hook, 

 the sides sometimes sharply angled. (Hasjjer as in mnacki, dorso-apical lobe rather 

 more pointed ; harpe sliorter ; processes above penis-sheath as in imificki, slightly 

 more slender.

 orifice, with a small smooth mesial tubercle pro.ximally of this incrassate ridge. 



Larva green, seldom cinnamon-brown, with red side-liands, which are inter-

c? ? . In contradistinction to AL dijras and most other species the external line 

 of the postdiscal pair is absent or vestigial, while the inner one is as distinct as 

 the exterior discal Hue. The apical area outside the postdiscal line of tiie under- 

 side of the forewing is not tawny as in c/i/ras. Antenna of c? very heavy, two-fifths 

 the length of the forewing, obviously longer and thicker than in d//ra.s ; that of 

 ? slightly compressed, very feebly grooved, seriated basal ciliae barely half the 

 length of the segment. Fringe of forewing //of wliite lictweon the veins. Month- 

 parts see PI. LXI. f. 11. 



c?. Tenth tergite (Fl. XXVI. f S) rounded at the sides, obviously broader 

 before the end than in the middle, tiie sinns narrow, the lobes notched, inner 

 angle acute ; sternite straight, not or very feebly bent upwards, narrow and long, 

 compressed, nijjierside rough with minute teeth. Dorso-apical lobe of clasjjer 

 (PI. XXXIV. f. 13) dagger-sJiaped ; the harjie irregularly notclicd and tubcrculated ; 

 processes above the penis-sheath very long and slender. 



?. Vaginal ridge convex in middle (PI. XVIII. f. K)), with a separate rounded 

 lobe (/) at eacli side of tlie orifice. 



Larva green ; oblique lines of pale prominent granules : head graunlose, a row 

 of granules from antenna upwards.
