Sphinginas 



A name commonly used for this genus is 

 Phlegethontius p roto p arce; caro li na (pl ate XXXIX) was 

 Carolina and 

 celeus called sexta because of the six orange-yellow 



spots on each side of the adult's abdomen, 

 and celeus was called quinque-maculatus because it has 

 five such spots. The general color of the adult Carolina is 

 grayish brown; celeus is much lighter and, among other 

 differences, the dark lines corresponding to the two outer 

 ones on the hind wings of Carolina are fused to form a 

 band and the three inner lines are distinctly zigzagged. 

 The mature larva of celeus may be distinguished from 

 that of Carolina by the fact that the lower ends of the light 

 markings on the side of the abdomen curve backward 

 below the spiracles (breathing holes). In the South 

 the pupae are sometimes called " hornblowers " because the 

 free tongue-case suggests a wind instrument. The larvae 

 are called Tobacco Worms or Tomato Worms, according 

 to the crop on which they are found. They also eat the 

 leaves of potato and other Solanaceas.

 tion. The shaded portions of the wings 

 (Plate XXXIX) are brown, tinged, on the hind wings, 

 with pink ; the dark spot near the angle of each hind wing is 

 purplish black. A western form, occidentalis, has whitish 

 front wings and largely pink hind wings. The larvae feed 

 on poplars and willows, pupating in the ground. Some 

 authors place this species in the Oriental genus Marumba. 



Holland explains the scientific name of 

 Sphinx the T w i n _ spot Sohinx as follows: "This 



jamaicensis . n j 



geminatus beautiful hawk moth was originally named 



and described in error by Drury as coming 

 from the Island of Jamaica. He also was so unfortunate 

 as to have had for his type an aberrant specimen in which 

 the ocellus of the hind wing had but one blue spot. Such
