has a black spot at the base, and a white line and two spots at the side, The expansion of the fore wings is 23 
inches or rather more. 
The caterpillar is at first green; but after the second moulting, it becomes of a brown colour or varied with 
yellow, with a dark stripe down the back, and several black or grey and yellow spots near the spiracles. The 
sides of the fourth and fifth segments are also ornamented with a large eye-like spot. It feeds on the yellow 
lady’s-bedstraw, willow herbs, the common vine, &c., and is full-fed in the month of J uly, the moth appearing 
in the following summer. It is widely distributed over our island, having been found in Devonshire, Cambridge- 
shire, various parts of Scotland, &c. It is far from uncommon in Hackney and Battersea marshes. The 
caterpillar is very subject to the attacks of a large black Ichneumon.

This species is considerably like the preceding, but much smaller, the expansion of the fore wings being 
generally about two inches. They are of an ochraceous olive colour, with the fore margin varied with rosy 
patches, and a rosy-coloured, irregular, broad, apical margin, and two dark oblique bars running across the 
wings. The hind wings blackish at the base, with a broad purplish hind margin. The head, thorax, and 
abdomen rosy or yellowish on the back ; the sides of the thorax with a tuft of whitish scales. The antenne and 
fringe of the wings are white. 
The caterpillar has the tail almost obliterated, and is of a blackish-brown or dirty-green colour, with a large 
blue eye-like spot at the sides of the fourth and following segment of the body. It feeds upon the same 
plants as the larve of the preceding species. 
Although much rarer than the preceding, it appears to be as widely distributed, having been found in many 
parts of the country, and sometimes rather plentifully. It occurs in the winged state at the end of May and 
beginning of June.

This genus is distinguished from all the preceding Sphingide by its diurnal flight and tufted tail; and from 
the following by its wings not being fenestrated. The palpi are porrected in front of the head, forming a short 
beak, having the second joint very large and rounded, and the terminal joint very minute (as in the true Sphin- 
gide). The antennz are clavate, with the tip hooked and scaly, and terminated by a few bristles. The 
maxillz and spiral tongue are very long, whence in fact the name of the genus; it being derived from the Greek 
sakpos, long, and yAdooa, the tongue. The larva, as in most of the preceding genera, is furnished with a caudal . 
horn ; and the pupa is concealed in a cocoon placed on the surface of the ground.
