HETEROPTERA,. — COREID. 483 
These insects are generally diversified in their colours, and are found 
upon plants or trees, upon the juices of which they appear to subsist. 
They run and fly well, especially in the heat of the day; Coreus 
marginatus in flight makes a humming noise as loud as the hive bee. 
In many of the exotic species the hind legs are singularly enlarged, 
especially in the males, the femora in many being greatly thickened, 
curved, and spined; whilst in others the legs are very long, the 
femora thin, and the tibiee furnished on each side with a broad and 
flat membrane, with the edges notched; the use of these singular 
appendages is involved in obscurity, the species not being saltatorial ; 
in some, again, the femora are thickened, and the tibiz curved and 
hooked at the tip, fitting to the femora like the fore legs of a Mantis ; 
the antennz also exhibit some curious modifications, the intermediate 
joints, or one of them, being occasionally dilated into a broad plate. 
M. V. Audouin has observed the eggs of Coreus marginatus to be 
of a splendid golden appearance. 
Some larvae and pupe which I possess of several of the species 
of Coreus (C. hirticornis, marginatus, and Scapha) differ from the 
imago in wanting ocelli, possessing only two joints in the tarsi 
(although there is a slight indication of an articulation in the middle 
of the terminal joint) ; their antennz also are much thicker, especially 
the intermediate joint; the pupa of C. Scapha differs also from the 
imago in having the margins of the abdomen notched (fig. 121. 14.). 
Some of the species of this family are of a very slender form; these 
belong to Latreille’s exotic genus Leptocoris (not of Burmeister) and 
the British genus Neiedes (fig. 121.16. N. tipularius), remarkable 
for the elbowed form of the antennz at the end of the long basal joint. 
I have found N. elegans in great profusion in all its states about the 
roots and young stems of a small plant of Ononis arvensis, at the back 
of the Isle of Wight. Its motions are very slow, and I did not 
observe it to make use of its wings. The larve and pupz were also 
found in company with the imago, and it appeared evident that it was 
from the plant that the insects derived their nutriment. 
The genus Chorosoma Curé. (Myrmus Hahn, Rhopalus Sch.) 
comprises species of an elongated form, one of which, C. miriforme, 
(Lyg. micropterus Burrell, in Trans. Ent. Soc. vol.i. p. 74. 1807.), 
ordinarily occurs, and is described as possessing only short hemelytra: 
such is indeed the common appearance of the insect, and I have re- 
peatedly captured such specimens tz copuld, although, at the same
