prominent. The proboscis is well developed. The larv?e have 

 the fifth segment broader than the anterior segments, which 

 are narrowed in front, and more or less retractile ; the fifth, 

 at least, and sometimes all the segments, marked with an 

 ocellated spot on each side ; the horn is slender, long 01 

 short, and sometimes obsolete ; the head is larger than in the 

 Macroglossiuce. They feed on low plants and shrubs, such as 

 bedstraw, spurge, willow-herb, oleander, and especially vine. 

 The pupa is formed among leaves, on the surface of the 

 ground. 



The attenuated and retractile front segments of the larvD3 

 give them a fancied resemblance to a hog's snout (whence the 

 name Chocrocampa^ or Hog-caterpillar ; not C/ucroaimpa, as 

 it is frequently written), or to an elephant's trunk, whence their 

 name of Elephant Hawk-moths. The moths fiy over flowers 

 in the evening, but their flight is less rapid than that of 

 Macroglossa. They are of moderate size, measuring from two 

 to five inches in expanse ; the majority of the species, however, 

 expand about three inches.

In this genus the head is conical, and the body stout and 



xather pointed at the end. The fore-wings are moderately 



long, narrow at the base, and widening outwards, the costa and 



inner margin being nearly straight for most of their length ;
