22 MANDIBDLATA. ORTHOl'TERA. 



entomologists respecting it, that it was peculiar to Britain : it occurs 

 in marshy districts towards the middle of July, and is found in those 

 about Camberwell, Deptford, &c. near London, and in the vicinity 

 of Whittlesea Mere. " In the fens of Cambridgeshire.""—

Sp. 6. elegans. Capite valde declivi, thorace carinis tribus rectis ; mas thoracis 

 dorso rufescente, elytris non coJoratis margine antico dilntato, corpore paullo 

 longioribus ; foemina Unea air a thoracis, elytris ohlongis non dilatatis corpore 

 brevioribus, vittd alba ad jjiarginem anticum. (Long. corp. 8 — 10 lin.) 



Gry. elegans. Charpentier Horcs Ent. 153. — Lo. rubroviridatus. Steph. Catal. 

 302. No. 3325. 



Head very much deflexed; thorax with three straight elevated lines, the 

 central one lightest and acute ; colour rosy-red, with the sides greenish^ or 

 testaceous, sometimes with a black streak accompanying the carinje ; in the 

 male the elytra are horn-colour, and dilated in front ; in the female they 

 are oblong, green or testaceous, with a long white streak towards the 

 margin at the base, accompanied by a broad dark one ; legs testaceous, 

 with the hinder femora slightly greenish, and obscurely tipped with dusky. 



Variable in colour, and in some examples the elytra are very faintly spotted 



with a dusky tint. 



This appears to be a rare species ; I foimd it in the marshes near 

 Whittlesea in July 1833. 



Sp. 7. dorsata. Thorace carinis lateralibus subrectis / supra viridis, suhtus 

 lateribusque fuscis, pedibus pallidis, geniculis concoloribus. (Long. corp. 

 8—10 lin.) 



Gry. dorsatus. Zettersted Orih. Suec. 82. — Lo. dorsata. Steph. Nomen. 2d edit. 

 Appendix. — Lo. ochropa, Steph. Catal. 301. No. 3322. 



Thorax with its lateral ridges nearly straight ; head above greenish-testa- 

 ceous, forehead considerably deflexed ; thorax rather narrowed anteriorly^ 

 smooth, fuscous, green, between the carina, and on each of the lateral lobes 

 (during life) is a splendid golden, or greenish-gold spot ; elytra in the male 

 rather longer than the abdomen, in the female of the same length as it, the 

 irmer or dorsal portion green, varying in tint in different individuals, the 

 outer or costal edge dusky or brown ; legs dull testaceous, the hinder ones 

 with the knees concolorous, and the tibiae paler. 



Rather variable, some examples having a pale line edged with dusky at the 

 base of the elytra; in others the elytra are pale; the thorax has sometimes 

 a black line on each side, or the prominent colour is rosy : several of these 

 varieties arise from the different states of maturity. 



This insect occurs, but not abundantly, in meadows in the vicinity 

 of the metropolis in July.
