spines ; spurs loiiji, almost c'i|iial, lung tcnniiial one of liiiicltibia nearly as long as 

 the tibia, or longer. Lobe SC'' of forewiug more prominent ; R- of bindwing in 

 or before centre of cell. Eighth steruite (<J) simply sinuate mesially ; fiiction- 

 patch of clasper large (PI. LVIII. f. 29) ; sternites without spinnles. 



Larva long and slender, head strongly triangular, horn very long, slightly 

 curved upwards ; granulose, a dorsal lateral and an interrupted ventro-Iateral 

 longitudinal line yellow ; seven white side-bands, bordered red in front ; white 

 dorsal nuirlcs on segments 4 to Hi. — Food-plant: not known, probably OreoddjilDif.

Seveu species. — The submarginal line of the forewing, if present, begins at 

 SC!'', not at the tip of the wing ; the discal lines of luniform bars are not obviously 

 curved costad in front. The posterior two-thirds of the mesothoracic tegula are 

 entirely occuj)ied by a dark olive-green patch. Tiie first tergite of the abdomen 

 is not concolorous with the rest of the abdomen. A lateral spot at the angles of 

 the frons white or grey like the terminal surface of tJie palpi.

 being spinose or not.
