SPHINX LUSCITIOSA 



GENUS, SPHINX. 



SPECIES, LUSCITIO'SA. 



We never had the eggs of this rare moth. We caught a 

 much-rubbed male flyiug over a fiehl of rape at whose 

 flowers it was feeding, and we could identify it very

 sphinx moths. Its fore wings were smoky brown, 

 blacker on the costa and outer margin, and the hind 

 wings were deej) ocher-yellow, almost orange, with a 

 wide black margin and a faint black band across each 

 wing. We found no female then, but later our one 

 caterpillar became a fine large female moth, larger 

 than the male and having the wings grayer. The yel- 

 low of her hind wings was very grayish yellow. 



It was near the rape-field that we found the cater- 

 pillar, a slender little one, only three quarters of an 

 inch long, feeding on a poplar by the roadside. Its 

 head was triangular, pale green, with pale yellow face- 

 lines. The body was green, densely covered with 

 white granules on the dorsum, but less so below the 

 subdorsal lines. There was a bright yellow lateral 

 line on the thoracic segments, extending faintly from 

 there to the caudal horn. The obliques were pale 

 yellow edged above with deep green, the last pair ex-
