LINNEAN SYSTEM. 
Genus 13. Cassida. 
Anlcnn/r. moniliform : thorax and elytra marginated: head conceale 1 * 
under the thorax : body above gibbous, beneath flat and margined- 
Of this genus we have several species, some of which are very brfl' 
liant in colours, wliich disappear when the insect dies, but are sak 
revive when put in warm water. 
The larva 1 of these insects are found under the leaves of the piano 
on which they feed: by means of the lateral spines and bristle at th 
end of the tail they form a kind of parasol with their own cxcremen 
to shelter themselves from the sun and rain, and probably to scree 
themselves from their enemies. 
Sp. 1. Cass, maculata. The elytra vary in colour, the young state ofth*- 
insect: being green, and as it advances in age gradually approachidy 
to red spotted with black: black on the under side. C. murraa 0 
Marsham is only a variety of this. (Pl. 2- Jig- 10.) 
Genus 11. Coccinelea. 
Antenna clavated : the club solid : maxillary palpi terminated by a larg® 
securiform joint: body hemispherical : thorax and elytra margined- 
abdomen flat. w 
The insects of this genus are commonly called in England Lady 
cows, or Lady-birds. The larva: feed chiefly on the Aphides or plaid' 
lice, and are very serviceable in clearing vegetables of the myriads wit 
which they are often infested. Mr. Marsham in his Entomologia B"' 
tannica has described 50 species, two-thirds of which only are genuin* 
So great is the variety in the species of this genus, that by a close e*' 
animation scarcely two specimens will be found alike: this shows 
necessity of collecting varieties, for by this means species may be d«' 
cidcd upon ; I should therefore strongly recommend the young end 1 ' 
mologist never to disregard them, as they tend greatly to the advau<^ 
meat of the. science, and certainly enrich a collection. Mr. Stephe' 
(the author of the continuation to the ornithological part of Sha' v - 
Zoology, and a most excellent entomologist,) for some years past b 9 ' 
paid great attention to this genus of insects; and it his intention to L*- 
his observations before the Lirmean Society. 
Sp. 1. Cocc. {4-guttata. Llyt.ra red: with fourteen white dots: an ten 119 
and eyes black : the spots on the elytra form four lines ; the first h 11 
contains two spots, the second six, the third four, and the last t"'°' 
Inhabits willows. (PL 2.)fg. 11.) 
Genus 15. Ciirysomet.a. 
Antenna; moniliform : palpi six, thickest at their extremity: thorax 
gined, but not the elytra: body for the most part ovate. j 
The insects of this genus are in general adorned with shining 9 , 
splendid colours. They live on leaves, but do not eat the nervo 1
