has a black spot at the base, and a white line and two spots at the side. The expansion of the fore wings is 2i 

 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 strii)e down the back, and several black or grey and yellow spots near the spiracles. The 

 sides of the fourth and fifth segments arc; 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 July, the moth appearing 

 in the following summer. It is widely distributed over our island, having been found in Devonshire, Cambridge- 

 shire, various i)arts of Scotland, ike. 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 ci)lour, 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 ]iur]ilisli 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 antennre 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 tlie same 

 plants as the larv;c of the preceding species. 



Although much rarer than the preceding, it appears to be as widely distributed, having been found in m.-iuy 

 parts of the country, and sometimes rather plentifully. It occurs in the winged state at the end of May and 

 beffinnins of June. 



MACRO(iLOSSA, Scopoii, Ochseniiei.mer. 



This genus is distinguished from all the preceding Sphingida; 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- 

 gidse). The antenna are clavate, with the tip hooked and scaly, and terminated by a few bristles. The 

 maxilla; and spiral tongue are very long, whence in fact the name of the genus ; it being derived from the Greek 

 jj-UKpos, long, and yXSxrcra, 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.
