 of the forewing is also not marked. A ]ieav3--bodied insect with comparatively 

 short wings, which is easily recognised by tlie very broad brown-black border of the 

 rosy red hindwing and the olive-yellow stigma of tlie forewing. 



c?. The tenth tergite smooth, rounded at the end, which is turned downwards, 

 longitudinally grooved ; the ninth tergite (proxinial ])art of the supra-anal process) 

 not liairy ; tenth sternite mesially ]irodnced into a triangular, apically rounded lobe. 

 CUasper obliquely rounded at apex (PI. XXXIV. f. 22), this apical lobe smaller than 

 tlie harpe, wliich is concave, spoon-shaped, with the apex produced into a pointed 

 hook, which is directed dorsad ; the dorsal edge of the clasper is widened internad 

 near the end of the harpe and densely beset with stiff hairs ; the dense tuft of hair- 

 scales near the apex of the harpe is about twice as long as the clasper is broad 

 before the end. Penis-sheath dorsally longer than ventrally, being obliquely 

 truncate, without external armature ; within the sheath tiiere is a membranaceous 

 flap densely covered witii pointed tubercles.

 flaps in front of tiie vaginal orifice, separated from one another by a deep sinus.
