﻿The broken antennae composed of only four joints, will readily 

 separate the genus Coreus from the Pentatomidtr^ whilst the 

 dilated abdomens with elevated margins will distinguish it 

 from other groups of the Corciche. 



The different species exhibit many variations of form in the 

 antenna?, especially of the basal joint, in the process between 

 them which in some is Ijifid, in the outline of the thorax and 

 abdomen, as well as in the number of lobes or teeth at the 

 apex. 



We are now able to enumerate five perfectly distinct British 

 species; the first of which only is common. 



1. C. marginatus Limu, U'oljf. tab. 3./. 20. 



Found in May and September in gardens and hedges upon 

 the dock. This insect has such rigid elytra and wiugs, that 

 when flying they create a very harsh sound. 



2. C. Scapha Fab. Nub. 



Amongst other characters which this insect possesses that 

 will distinguish it from the foregoing one, is the simple spuie 

 between the anteima>, which in that species Is cleft. The end 

 of last August I ibund the larva and two specimens at the base 

 of the ClilTnear Dover, and in September another in the Isle 

 of Wight. 



3. C. (juadratus Fab.^ Jfol/f. t. l-f. (J7. — veiuitor Don? 

 11. 375. 



Found in June and August in hedges. 



^. C. scabricornis Panz. 99. 21. 



5. C. denticulatus Scop.^ J^^^lfT- ^' '•■./• ^'^^- — hirticornis Fab.^ 

 Panz. 92. 1 7. 



Inhabits sandy places in June. 



The plant figured is Crithmum maritimum (Rock Samphire), 

 and was obtained from the celebrated Shaksjieare Cliff* near 

 Dover; it was also growing above the spot where the insects 

 were found.
