(??. Antenna shorter than in Meganoton, liook shorter, peiinltimate segment 

 about as long as high, the preceding ones shorter than high. Palpns differing from 

 tliat oi all the other sjiecies of the present subfamily in the second segment having 

 a nahed strijje over tlie inner surface (as prolongation of the naked stripe of the 

 first segment). Labrnra very little raised in middle. First segment of foretarsus 

 somewhat longer than segments 2 to 4 together ; comb of midtarsus well develoj)ed, 

 that of hindtarsns as in Meganoton ; long spur of midtibia about A, the long apical 

 one of hindtarsns nearly g, the length of the respective first tarsal segment. 

 Pulvillus and paronychinm present, the latter with one lobe on each side. 



cj. Clasper with patch of modified scales, the scales large, rounded, entire, 

 mnltistriate ; harpe vestigial (PI. XXXV. f. 20), represented merely by a thickly 

 scaled slight incrassation of the ventral margin of the clasper ; process of penis- 

 sheath short, forked. No friction-scales on the inner surface of eighth tergite. 



? . Antenna subcylindrical, ciliae not prolonged. 



Larva : thoracical tergites with small conical tubercles, arranged in transverse 

 rows ; head minutely grauulose all over, somewhat narrowing above ; horn and 

 anal segment very rough with conical tubercles, horn curving upwards, --shaped ; 

 dichromatic, one form green with white oblique stripes, the other with a broad 

 brown dorsal band, constricted on each segment, beginning on the third thoracical 

 segment, large lateral and ventral patches also brown. 



Chrysalis with a long free tongue-case which is not recurved. 



Ilah. Oriental Region. — Only one s[)ecies. 



The genus is a development of Meganoton, being more specialised in the palpi 

 and paronychinm. 



As will be seen from the above synonymy, the species has been treated under 

 seven generic names. The reference to Ps^^/r/os/^///wr— proposed by Burmeister 

 for a Sphingid belonging to another subfamily — is wild, to say the least.

(S ? . Variable in colour and size geograjihically and individually ; in most
