blLEPIIILA. 3t 



Stripe on each side, which broadens towards the base of tlie 

 fore-wings. The abdomen is also oHve-green, with a white 

 hne down the centre, and two black spots on each side, fol- 

 lowed by a white one below each. The other segments are 

 also bordered behind with white on the sides. 



The full-grown larva is of a lighter or darker shade of olive- 

 green, or may be almost black, with a yellow dorsal line, and 

 a row of large, round, pale yellow spots, bordered with black, 

 on the sides. The horn is red, and the belly and legs reddioh- 

 yellow. 



It is found from July to September on bedstraw {Gah'i/>n 

 veruni, and G. niollugo), on Riibia tincforu/n, and on fuchsias 

 in gardens. 



The pupa is reddish-brov/n. 



This species is widely distributed in the southern part of 

 the Palcearctic Region, but does not extend very far north. 

 It is more frequently met with in England than others of the 

 genus, and though the moth is rarely taken, the larvae are 

 sometimes found, not uncommonly on sandhills on the south 

 coast, feeding chiefly on bedstraw. Yet it is doubtful whether 

 it is truly indigenous in the sense of being thoroughly accli- 

 matised, for Dr. Knaggs states that, although the pupai can 

 be reared by forcing, with the greatest success, yet if not 

 forced, they almost invariably die during the winter. This 

 appears to indicate that the larv^ found in England are 

 the produce of the eggs of moths which have crossed the 

 Channel, but that something in our climate is so unfavourable 

 to them that comparatively few British-hatched specimens ever 

 succeed in reaching the perfect state. 



There is a North American species closely allied to £>. 

 gain, from which some authors, indeed, consider it hardly 

 distinct. It is called VilcpJiila inUr/ncdia (Ivirby) {D. 

 chamcenerii^ Harris).
