deigns not to alight, or toacli the margin of the chalu e ; 
but, poising itself in the air, stretches out its long tubular 
tongue, and quaffs the nectar at the bottom,” Unlike 
the last species, the Convolvulus Hawk-Moth is oftener 
seen in the perfect state than in the preparatory stages ; 
indeed, the caterpillar, which feeds on the bind weed and 
other plants, has very rarely been seen in Britain, though 
the moth is nob unfrequent throughout the country. It 
is, however, variable, like many others of the hawk-moths, 
appearing commonly one year, and then almost disappear¬ 
ing for several seasons. The year 1846 was a great year 
for this moth, many hundreds having been found through¬ 
out the country. At Perth it occurs almost every year, 
baviniz been found even in the centre of the town. 
4. The Madder Hawk-Moth (Deiliphila Galii) is about 
half the size of the last, but is much prettier. The fore- 
wings are olive brown, with a broad white stripe; the 
biudwings black, pink, and white. The caterpillar is 
very beautiful, being generally blue-green above and 
pinkish below, a yellow liue down the middle of the back, 
a row of ten eye-like yellow spots on each side, and the 
born red. The chrysalis is brown. This moth has only 
once been found near Perth, and that was in the autumn 
of 1859, when about two dozen caterpillars were found 
feeding on the yellow ladies-beJstraw. It has probably 
nob been found north of Perth in Britain, though occur¬ 
ring in ail the southern parts of the country, but not 
commonly, except t>erbaps at Beal. The caterpillar is 
said also to feed upon fuschias, and the moth to frequent 
flo wers in the early morning. The name Deiliphila signi¬ 
fies “ lover x)f twilight.” 
5. The Silver-striped Hawk-Moth (Cli(Brocampa Celerio) 
is decidedly the rarest of the hawk-moths of Perthshire, 
and is by some entomologists considered doubtfully 
Biitish. It is about the same size as the la^t, and has 
brown forewings, with a silver stripe running across the 
wing to the extreme tip. The hindwings are pink and 
pinkish brown, with two black bands. The body is long 
and sharp-pointed, with three rows of white spots. The 
caterpillar (which in this genus (Cli(£rocampa) has the 
bead small and the anterior segments retractile, is green 
or purplish brown ; on the fifth and sixth segments, two 
round black spots circled and dotted with yellow ; the 
horn brown, straight, and slender. It feeds on the vine 
and the yellow ladies-bedstraw, a plant which seems a 
favourite with many of the hawk luoLhs. Several speci-
