DESCKIPTIVE NOTICES OF CONSPICUOUS SPECIES 131 



grows profusely. Sometimes it is found in gardens 

 feeding on the leaves of fuchsias. 



The perfect insect emerges from the pupa between 

 the middle of July and the middle of August. It is 

 sometimes met with hovering over flowers at dusk. 



There are two closely allied species, the Spurge Hawk- 

 moth (Deilephila euphorbias), and the Striped Hawk- 

 moth (D. Livornico) ; the former used to occur on the 

 sand-hills at Braunton Burrows, near Bideford, but has 

 not been met with for many years. The perfect insect 

 closely resembles Deilephila galii, but the dark streak 

 from the apex to the middle of the inner margin meets 

 the inner margin much further from the base of the 

 wing ; the larva feeds on the sea spurges (Euphorbia 

 Ciiparissias and Euphorbia Par alias), which grow on 

 sand-hills near the coast. 



D. Livornica can be easily recognized by the veins of 

 the fore-wings being distinctly whitish ; it is a scarce 

 species, but occasionally occurs in various parts of the 

 country in May, August, and September. 



FAMILY II. SPHINGID.E. 



CHJEROCAHPA ELPENOR. THE ELEPHANT 

 HAWK-MOTH. 



This pretty species is very common throughout the 

 southern and midland counties, but becomes scarcer as 

 we advance further towards the north. 



The expansion of the wings is about 2 J inches. The 

 fore-wings are dull yellowish-green, with the costa, the 

 hind-margin, and two oblique bands of a delicate rosy 

 hue; the hind-wings are rosy, with the basal half 

 blackish.
