sand-hills, in gardens, and in clearings in woods. The moth and larva are figured at PI. 18, 

 Fig. 2, a, b. 



7. D. Dahlii (Geyer). — Much resembles Galii, but the pale band of the fore-wings is whitish- 

 grey, and suffused internally ; the pale hind margin is much better defined, and the green space 

 between them is generally slightly veined with whitish. The hind-wings are black, v>ith a central 

 flesh-coloured band, a narrow marginal one, and a white spot towards the anal angle. Fringes of 

 all the wings white. Expands from 2\ to 2\ inches. It is found in June and September in Corsica 

 and Sardinia. The larva is slaty-grey, dotted with white, with alternate red and yellow stripes on 

 the back, and a yellow streak on the sides. There are two large white spots and three smaller 

 ones, all surrounded with black, on the side of each segment. The horn, legs, and spiracles are red. 

 It feeds on Euphorbia. 



*8. D. Livornica (Esp.). — Fore -wings olive-brown, with white veins. The hind margin is 

 ashy, and a yellowish streak runs from near the base of the inner margin to the tip. Hind-wings 

 rose-colour, with the base black, and a rather broad black band very near the hind margin ; fringes 

 whitish. There is a white stripe on each side of the thorax, and two others in the middle. The 

 abdomen has a row of white dots in the middle, and the front segments are spotted with black 

 and white on the sides. Expands from 3 to 3i inches. This species is found in August and 

 September, and sometimes emerges from hybernated pupa; in May. It is very widely distributed, 

 occurring throughout Southern and Central Europe, including England and Ireland, as well as 

 throughout Africa, and over the whole of the southern half of Asia. Indian specimens are 

 generally smaller than European. In North America it is represented by the closely-allied 

 D. Lineata (Fabr.), which is distinguished by having two additional pale lines on the thorax. 

 D. Livornica is rare everywhere in Central Europe, and appears rather to be a regular visitor 

 during warm seasons than a permanent resident north of the Alps. It is generally captured in 

 gardens in the evening, in company with the much more abundant Sphinx Convolviili. The 

 larva has a rosy streak on the back and a yellow one on the sides, with an intermediate row of 

 black and rosy spots. It lives on a great variety of plants, among which we may mention 

 sorrel, toadflax, bed-straw, fuchsia, and vine, and may be looked for in June and July. 



GENUS IV. — CHCEROCAMPA (DUP.). 



The perfect insect resembles Deilephila, but the fore-wings are rather narrower and more 

 pointed, owing to the costa being more strongly arched, and the hind margin generally a little 

 concave. The abdomen is longer and more tapering. The larvjE are generally green or brown, 

 with the front segments tapering and retractile, and eye-like spots on the sides of the 4th, 5th, or 

 6th segments. The peculiar structure of the larvae has led to their being thought to resemble an 

 elephant's trunk or a hog's snout, whence the moths derive their name of Elephant Hawk-moths, or 

 Charocaiiipa, from ^oipoi;, a hog, and Ka/nn], a bending. This genus, which may be divided into 

 several sections, is very widely distributed, and has representatives in all parts of the world. 



* I. C. Celerio (Linn.), (Sharp-winged Haivk-viotii). — Fore-wings olive-brown, with short black 

 and silvery longitudinal lines, and a shining silvery wavy streak, divided by two fine brownish lines, 

 running from the base of the inner margin to the tip, below which are whitish longitudinal 

 lines running along the hind margin. A little below the middle of the costa is a black spot in a 

 pale ring. The hind-wings are rose-colour, with the hind margins and a central streak broadly 

 black. The intermediate rosy band is also divided by black veins. Expands about 3 inches. It is 

 found in May and June, and again in autumn, and its di=itribution is similar to that of Deilephila
