The Modest Sphinx, Marumba modesta (Ma-rum'ba 

 nio-des'ta). — It was, probably, the quiet olive tints in which 

 the moth is chiefly clothed that suggested the name modesta 

 for it, but it is one of the most beautiful of our Hawk-moths. 

 The body and basal third of the fore wings are pale olive ; 

 the outer third of the fore wings is a darker shade of the 

 same color ; while the middle third is still darker (Fig. 409). 



FlG. 409 — Marumba modesta. 



The hind wings are dull carmine-red in the middle ; there 

 is a bluish-gray patch with a curved black streak over it 

 near the anal angle. The larva feeds on poplar and cotton- 

 wood. When full grown it is three inches long, of a pale 

 green color, and coarsely granulated, the granules studded 

 with fine white points, giving the skin a frosted appearance.

 rin'thus gem-i-na'- 

 tus). — This exquis-

 The thorax is gray
