spiues ; spurs long, almost ecjiital, long terminal one of Iiindtibia nearly as long ad 

 the tibia, or longer. Lobe S(J'' of forewing more prominent; R- of hindwing in 

 or before centre of cell. Eighth sternite (c?) simply sinuate mesially ; fiiction- 

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



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

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

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

 SO^ 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 occupied by a dark olive-green patch. The first tergite of the abdomen 

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

 the frous white or grey like the terminal surface of tlie i)alpi. 



The seven species fall into two well-defined groups according to the tibiae 

 being spinose or not.
