wards, thus bringing the beak close to the bases of the fore legs. The Heteroptera are almost 

 without metamorphosis, the newly-hatched young closely resembling the adult except for the 

 absence of wings, which are gradually developed as the insect approaches maturity. Among 

 the Homoptera, however, metamorphosis is more marked, the young frequently bearing little 

 resemblance to their parents. 



The great majority of the British Hemiptera are vegetable feeders, living on the juices of 

 plants ; a few of the Heteroptera, however, are blood-suckers. Some of the Homoptera have the 

 remarkable habit of enveloping themselves in their earlier stages in a mass of white froth, as in 

 the well-known ' cuckoo-spit ' frog-hoppers. 



The Heteroptera are sub-divided into two groups : (i) the Gymnocerata, comprising all the 

 terrestrial forms, and the ' pond-skaters,' which live on the surface of water, are characterized by 

 possessing large and conspicuous antennae ; (2) the Cryptocerata are truly aquatic insects with very 

 small antennae which are hidden beneath the head. To this group belong the water-scorpion 

 and the water-boatmen, the latter having the curious habit of swimming on their backs. 



Unless otherwise stated the species enumerated below have all been collected by the 

 Rev. Alfred Thornley, with the exception of a few species collected by myself. The Aphides 

 and Coccidae of Nottinghamshire are practically untouched, and no list of these can yet be 

 given. 



The arrangement and nomenclature adopted are those of the Catalogue of British Hemiptera, 

 by E. Saunders and J. Edwards.
