CHRYSALIS. A term in the hiftor/ of in- 
feds of fiinilar import with Aiirelia, for which it is 
indifcriminately ufed. 
The word Chryfalis, from Chrufos, Gold, feems 
to imply a peculiar yellow, or golden colour, ufu- 
ally found in the nymphre of fome fpecies of in- 
fers ; but this is merely accidental, as it is not 
perceptible in all nymphas. Some, however, con- 
fine the extent of the appellation Chryfalis to the 
hymphje of butterflies and moths, 
CHRYSOMELA. A genus of infeds fre- 
quently confounded with beetles, the antennx of 
which are formed like bracelets, or necklaces of 
beads, and are thickefl: towards their extremities. 
The body is of an oval figure ; and the thorax is ob- 
' long and rounded. This genus contains a variety 
of fpecies. 
Chrysomela, 'Blue-Green. This is one of the 
largeft fpecies of the kind, though far from being 
a confpicuous infeft. The head is fmall, the legs 
are flender, and the belly is fmooth. The back is 
roundifh, or convex and the colour is an admix- 
ture of blue and green, with a very fine tin6lure of 
gold-colour diffufed over the whole. The mar- 
gins of the cafes of the wings are fomewhat promi- 
nent, and marked with a few hollow fmall Ipots en- 
tirely furrounding them; and the feelers, legs, and 
belly, are green. It is commonly found in mea- 
dows during the months of May and June. 
Chrysomela, Red-Breasted. The cafes of 
the v/ings of this infedl are reddifh ; and the head is 
fmall and black, as well as the body, legs, and the 
lower part of the bread and feelers. It is feen on 
fome fpecies of willow-trees in June and July. 
Chrysomela, Blue- Green, with a red breaft 
and thighs. The head and cafes of the wings of 
this fmall animal are of a beaut'ful Ihining green, 
with a tinge of blue ; there arc a few hollow fpots 
on the head ; the breall is fmall, convex, and of a 
reddifh colour, with a caft of blue-green ; and the 
upper parts of the legs are reddifh, and the under 
black. It is common in moft parts of this king- 
dom. 
Chrysomela, Black. This pretty large in- 
feft is entirely black. The breafl and caf es of the 
wings are marked with fmall hollow points placed 
very near each other; the wings are flexible, foft, 
and blunt; and the feelers confift of twelve joints. 
It refides in quarries, and has a flow, creeping mo- 
tion. 
Chrysomela, Smooth Black. The bafes of 
the feelers of this infedl are yellowifh ; the joints of 
the wings are neither hollow nor ftriated ; but the 
black colour with which this animal is covered ex- 
hibits a blueifli caft. 
Chrysomela, Purplish Black. This infeft 
is found on the birch-tree, on the leaves of which 
It feeds. The colour is a blackifh blue inclining 
to purple, or rather to violet ; the belly, feet, and 
feelers, are black ; t^ head and breaft are marked 
with minute hollow, irregular points ; the cafes of 
the wings are flreaked ; and the eyes are fo fmall as 
to be hardly perceptible. 
Chrysomela, Purplish Black, fprinkled with 
hollow points. This fpecies nearly refembles the 
former, except that it is larger, and that the cafes of 
the wings are marked with hollow points irregu- 
larly difperfed, but not flreaked. It is found, dur- 
ing the vernal feafon, on alder-trees. 
Chrysomela., Purplish Black, with thebreaft

yellow. This infeft frequents the willow, and is 
entirely of the fame colour, fhape, and fize, of the 
former, except that tlie breail is yellow on the fides, 
round in the middle, and of a violet-colour, but 
fomewhat blacker on the centre. The head and 
lower belly are black; and in the middle of the red 
on the breaft there appears a black point. 
Chrysomela, Shining Green. Tlie breaft of 
diis infe6l is fmooth; and the cafes of the wings 
are marked with hollow points, which touch each ' 
other. Towards the vent, this animal becomes of 
an obtufe figure; and it feems to expand the cafes of 
it's wings with difficulty. The feet and feelers 
are black; and the breaft is very flightly marked 
with points. It is found on willows. 
Chrysomela, Shining Green, with the breaft 
hollow before. In this ipecies the breaft is only 
hollowed at the top ; and in other refpedls it refem- 
bles the preceding. 
Chrysomela, Shining Green, with a flat 
breaft. This fpecies differs from the former in 
being fomewhat lefs, and of a rounder figure. 
Chrysomela, Pale Green. This infc£t is 
found on willow-trees ; and is diftinguifhed from 
the other varieties by the palenefs of it's colour, and 
the nine rows of points placed lengthwife on each 
cafe of the wings. The eyes are black; and the 
bottoms of the feet are v/hite. 
Chrysomela, Red, with a cylindraceous breaft. 
The flower-de-luce afi-brds flielter to this variety. 
It is of the middle fize ; the breaft, the cafes of the 
wings, and the top of the head, are red; but the 
feelers, eyes, knees, belly, breaft-plate, and the un- 
der-part of the head, are black. The breaft-plate, 
which is confiderably narrower than the caies of the 
wings, is hollow on each fide; and the cafes of the 
wings themfelves are marked with hollow points of 
a moderate fize. 
Chrysomela, Copper-Coloured. This ani- 
mal is commonly found on willows, is of a middle 
fize, and appears like red copper higlily polilhed. 
Chrysomela, Blackish Blue, with red cafes 
to the v/ings. This infed is found on the poplar- 
tree in the beginning of fpring. It is a pretty large 
animal; it's red wings are marked with fmall points ; 
and the extremity of each cafe of the wings has a 
black fpot. The breaft is fmooth, and of a green- 
ifli-black colour; and the corfelet, belly, and feet, 
are of the fame colour; but the feelers are black. 
The cafes of the wings of this kind are not com- 
poled of plates, or leaves, but feem to be made up 
of eleven joints, the laft of which is the largeft. 
Chrysomela, Red, Cylindrical-Breasted, 
with red cafes to the wings. This fpecies is found 
on the branches of the afparagus, on the ftalks of 
which it fiibfifts. It is a fmall infe6t; the head is 
of a blackifli blue colour; the feelers are black; and 
the breaft, which is narrow and cylindrical, is marked 
behind witii two black points. The cafes of the 
wings are oblong, yellow, and very pale on their 
external edges; and on each of them there is a bluer 
fpot refembling a crofs. 
Chrysomela, Green-Breasted, with red cafes 
to the wings marked with a blue crofs. The co- 
lour of the head and breaft of this infcd is a cop- 
per green; die feelers and feet are black; and the 
tints over the whole body are elegant and at- 
traftive. 
Chrysomela, Oblong Black, widi red cafes 
to the wings marked with four black fpots. Tliis 
is a pretty large fpecies, and of a roundifli fhape. 
There are two large Ipots on each cafe of the wino-.s
