SPHINGID^. 275 



The species are said to fly heavily and only in the night. The 

 head of the larva is semi-oval or i)yrauudal, acute above, and 

 the thoracic rings are obliquely banded on each side. The 

 pupa is smooth, c^diudrical and somewhat conical in form. jS. 

 modestas Harris is a very large species, expanding nearly six 

 inches. It feeds on the Lombardy poplar. S. exccecatus Smith 

 has the hind wings rosy on the inner angle. The "ocellus" or 

 eye-like spot is black, with a large, pale blue pupil. The 

 larva is apple green, with seven oblique, yellowish white lines 

 on the sides, and a bluish caudal horn. It feeds on the apple 

 and the Rosa Carolina. >S'. geminatus Saj^ (Fig. 202, venation 

 of the hind wing) is so called from the two sky-blue pupils in 

 the black ocellus on the roseate hind wings. 

 The pupa has been found at the roots of 

 willows. 



In the genus Philmnpelus, or lover of the vine, ^^ 

 as its name indicates, the tongue is again as long ^'o- '^^• 

 as the body. The antenna? haA'e a long hook tapering to 

 the end, bearing cilite in the male. The abdomen is large and 

 thick, and the wings are deeply concave on the inner border. 

 The larva has a tubercle in place of a caudal horn. The 

 tongue-case of the pupa is not free. P. vitis Harris is olive 

 green, with pale green hind wings, which are rose-red towards 

 the inner margin. The larva is flesh-colored mixed with yel- 

 low, and with short, transverse, black lines, and lateral, semi- 

 oval, yellowish white bands, edged with black. 



In Deilephila the abdomen tapers suddenty at the tip and 

 the fusiform antennne end in a minute hook. The gaily colored 

 larva has a straight and rather short caudal horn. There are no 

 oblique bands on the sides of the body, but a row of subdorsal 

 spots on each side. Clemens states that the anterior segments 

 are much attenuated, and are capable of being withdrawn or 

 shortened, or much extended. " When disturbed they fall from 

 their food-plants, shorten the anterior segments and bend the 

 head inwards." They transform in a cell excavated from the 

 surface. The tongue-case of the pupa is net free. D. lineata 

 Fabr. is olive green, with six white lines on the thorax. The hind 

 wings are black with a rose colored central band. The larva is 

 yellowish green ; the subdorsal spots consisting of two curved,
