This extensive genus contains some of the most brilliant 

 exotic insects, and of the most extraordinary forms. Their 

 economy is remarkable, and may be investigated by any one 

 who will take the trouble to search the common thistles or 

 horse-mint, upon which the two first species in our list feed in 

 their larva state, and they will be amused and greatly assisted 

 in their researches by consulting the 3rd vol. of Reaumur, the 

 Linnean Transactions, and the Introduction to Entomology. 

 Our British species, as is frequently the case, cannot vie 

 with the extra-European in brilliancy, although we possess a 

 considerable number, most of them being either green or 

 brown, with the exception of two or three, which when alive 

 exhibit a most beautiful metallic appearance, which we regret 

 cannot be done justice to in a coloured engraving.

The most striking character in C. Salicornice, which holds 

 in both sexes, is the totally pale thighs, which are black at 

 the base in C. nobilis^ and a much broader pale margin round 

 the abdomen of the male than in that species as described by 

 Gyllenhal, who has given the C. splendidula of Marsh, as a 

 variety of C. nobilis, varying in the colour and form of the 

 metallic stripe. It may be here remarked, that after death 

 these beautiful stripes disappear, but it is stated that they may 

 be restored by immersion in hot water; with regard to our 

 species also, the antennae become fuscous towards the extre- 

 mity, as well as the tarsi and apex of the tibiae. 



The species we have called C. anglica is small, orbicular, 

 and after death retains the pretty green colour it is possessed 

 of when alive : under a lens it is reticulated, which gave rise 

 to the name it has been known by hitherto in the London 

 and Norfolk collections, but which cannot be retained, having 

 been already employed by Fabricius for a very different species. 



The Rev. T. Skrimshire kindly communicated the sexes of 

 this beautiful insect, which died before I received them; and 

 as I despaired of ever obtaining living specimens, the plant 

 upon which they were found in May and June, and intended 

 to accompany them, was published in the 1 19th plate; that now 

 introduced is Cochlearia Danica (Danish Scurvy-grass) which 

 I gathered this spring at Southwold, on the coast of Suffolk.
